WARNING! Federal law (49 cfr part 571) requires that the Final Stage Manufacturer of
a vehicle certify that the vehicle complies with all applicable federal regulations. Any
modifications performed on the vehicle prior to the final stage are also considered
intermediate stage manufacturing and must be certified as to compliance. The installer of
this crane and body is considered one of the manufacturers of the vehicle. As such a
manufacturer, the installer is responsible for compliance with all applicable federal and
state regulations, and is required to certify that the vehicle is in compliance.
WARNING! It is the further responsibility of the installer to comply with the OSHA
Truck Crane Stability Requirements as specified by 29 CFR part 1910.180 (C) (1).

Auto Crane products are designed to provide many years
of safe, trouble-free, dependable service when properly used
and maintained.
To assist you in obtaining the best service from your
crane and to avoid untimely crane and/or vehicle failure, this
manual provides the following operating and service
instructions. It is specifically recommended that all
operating and service personnel consider this manual as
mandatory material for reading and study before operating or
servicing Auto Crane products. It is highly recommended
that crane owners, equipment managers and supervisors also
read this manual.
Auto Crane has incorporated several safety features in
the 3203P/PR/PRX Series cranes for your protection. The
choice of materials and the design of the electrical system
minimizes weight and lengthens durability. The hydraulic
components meet or exceed a 3.5:1 safety factor. Holding
valves prevent the load from dropping if a hose should fail.
The reservoir has a 40uair filter in the filler cap. The pump
has a 100 mesh strainer in the suction line.
For your convenience the overall dimensions of the
3203P/PR/PRX Series cranes are on the General Dimension
Drawing. Maximum turning radius is shown at the outside
edge of the guard (PR/PRX models) and the outside point of
the hoist actuator (P model).
Remember, the crane adds weight to the vehicle.
Adding weight may change the driving and riding
characteristics of the vehicle unless the appropriate overload
spring(s) are installed on the truck. The payload of the
vehicle is reduced by the weight of the crane. The operator
should exercise care when loading the vehicle. Distributing
the payload on the vehicle evenly will greatly improve the
driving and riding characteristics of the vehicle. A minimum
G.V.W. of 8,000 lbs. with two rear jacklegs (or outriggers)
is recommended for mounting the 3203P/PR/PRX crane.
The 3203P/PR/PRX crane is attached directly to your
12 volt truck electrical system. The performance of your new
crane depends on the truck electrical system. The use of the
low maintenance battery is not recommended for use on any
Auto Crane product. The recommended alternator and battery
that will give the longest life with the most useful duty cycle
is a 60 amp. alternator with a 120 minute reserve capacity,
deep cycle battery. These specifications should be considered
minimum.
Auto Crane Company issues a limited
warranty certificate with each unit sold.
See last page for warranty policy.
It has always been Auto Crane Company policy to handle
all warranty claims we receive as promptly as possible. If a
warranty claim involves discrepant material or workmanship,
Auto Crane will take immediate corrective action. It is
understandable that Auto Crane company cannot assume
responsibility of liability when it is obvious that our products
have been abused, mis-used, overloaded or otherwise
damaged by inexperienced persons trying to operate the
equipment without reading the manual.
Auto Crane will not assume responsibility or
liability for any modifications or changes made to
unit, or installation of component parts done without
authorization.
Auto Crane maintains a strong distributor network and a
knowledgeable Customer Service Department. In most cases,
an equipment problem is solved via phone conversation with
our customer service department. The customer service
department also has the ability to bring a local distributor, a
regional sales manager, or a factory serviceman into the
solution of an equipment problem. If, through no fault of
Auto crane company, it is necessary to send an experienced
factory serviceman on a field service call, the rates stated in
the Auto Crane Distributor's Flat Rate Manual will apply.
Auto Crane Company's extensive Research and
Development Program allow our customers to use the best
equipment on the market. Our Engineering Staff and our
knowledgeable sales people, are always available to our
customers in solving crane and winch-type application
problems. When in doubt, call the Auto Crane factory.
DISTRIBUTOR ASSISTANCE:
Should you require any assistance not given in this
manual, we recommend that you consult your nearest Auto
Crane Distributor. Our distributors sell authorized parts and
have service departments that can solve almost any needed
repair.
NOTE: THIS MANUAL SHOULD
REMAIN WITH THE CRANE AT ALL
TIMES.
This manual does not cover all maintenance, operating,
or repair instructions pertinent to all possible situations. If
you require additional information, please contact the Auto
Crane Company at the following telephone number: (918)
836-0463. The information contained in the manual is in

HANDLING THE LOAD
18 Size of load
A.No crane shall be loaded beyond the rated load
except for test purposes.
B.The load to be lifted is to be within the rated load of
the crane and its existing configuration.
C.When loads which are not accurately known are to
be lifted, the person responsible for the job shall
ascertain that the weight of the load does not exceed
the crane rated load at the radius at which the load
is to be lifted.
19 Attaching the load
A.The load shall be attached to the hook by means of
slings or other devices of sufficient capacity.
B.Hoist rope shall not be wrapped around the load.
20 Moving the load
A.The operator shall determine that:
B.The crane is level and, where necessary, the
vehicle/carrier is blocked properly.
C.The load is well secured and balanced in the sling or
lifting device before it is lifted more than a few
inches.
D.Means are provided to hold the vehicle stationary
while operating the crane.
E.Before starting to lift, the hook shall brought over
the load in such a manner as to minimize swinging.
F.During lifting care shall be taken that:
1.there is no sudden acceleration or
deceleration of the moving load.
2.load, boom or other parts of the crane do
not contact any obstruction.
G.Cranes shall not be used for dragging loads
sideways.
H.This standard recognizes that articulating boom
cranes are designed and intended for handling
materials. They do not meet personnel lift or
elevator requirements. Therefore, no lifting,
lowering, swinging or traveling shall be done while
a person is on the hook or load. Hook attached
suspended work platforms (baskets) shall not be
used with cranes covered by this standard. Work
platforms attached to the boom must be approved by
crane manufacturer.
I.The operator should avoid carrying loads over
people.
J.When the crane is so equipped, the stabilizers shall
be fully extended and set. Blocking under stabilizers
shall meet the requirements as follows:
1.strong enough to prevent crushing.
2.of such thickness, width and length as to
completely support the stabilizer pad.
K.Firm footing under all tires, or individual stabilizer
pads should be level. Where such a footing is not
otherwise supplied, it should be provided by
timbers, cribbing, or other structural members to
distribute the load so as to not exceed allowable
bearing capacity or the underlying material.
L.In transit, the boom shall be carried in stowed
position.
M.When rotating the crane, sudden starts and stops
shall be avoided. rotational speed shall be such that
the load does not swing out beyond the radius at
which it can be controlled.
N.The crane shall not be transported with a load on
the hook unless recommended by the manufacturer.
O.No person should be permitted to stand or pass
under a suspended load.
21 Stowing procedure. Follow the manufacturer's
procedure and sequence when stowing and
un-stowing the crane.

MISCELLANEOUS
OPERATING NEAR ELECTRICAL POWER
LINES
22 Cranes shall be operated so that no part of the crane
or load enters into the danger zone shown above.
EXCEPTIONS
A.The danger zone may be entered after confirmation
by an appointed person that the electrical
distribution and transmission lines have been
de-energized and visibly grounded at the point of
work; or
B.The danger zone may be entered if insulating
barriers (not a part of nor an attachment to the
crane) have been erected to prevent physical contact
with the lines.
23 For lines rated 50 kV or below, minimum clearance
between the lines and any part of the crane or load
(including handling appendages) shall be 10 ft. (3m).
For higher voltages, see Table 1.
24 Caution shall be excercised when working near
overhead lines, because they can move horizontally or
vertically due to wind, moving the danger zone to new
positions.
25 In transit with no load and boom lowered the
clearance shall be specified in Table 1.
26 A qualified signalperson shall be assigned to observe
the clearance and give warning before approaching
the above limits.
A.Any overhead wire shall be considered to be an
energized line unless and until the person owning
such line or the electrical utility authorities verify
that it is not an energized line.
B.Exceptions to this procedure, if approved by the
administrative or regulatory authority if the
alternate procedure provides equivalent protection
and set forth in writing.
C.Durable signs shall be installed at the operator's
station and on the outside of the crane, warning that
electrocution or serious bodily injury may occur
unless a minimum clearance of 10 ft. (3.0m)
between the crane or the load being handled and
energized power lines. Greater clearances are
required because of higher voltage as stated above.
These signs shall be revised but not removed when
local jurisdiction requires greater clearances.

with proper operation - daily, when used
B.control mechanisms for excessive wear of compo-
nents and contamination by lubricants or other
foreign matter
C.safety devices for malfunction
D.all hydraulic hoses, particularly those which flex in
normal operation of crane functions, should be
visually inspected once every working day, when
used
E.hooks and latches for deformation, chemical
damage, cracks, and wear. Refer to ANSI/ASME
B30.10
F.rope reeving for compliance with crane manufac-
turer's specifications, if optional winch is used

lubrication is specified, should be regularly
lubricated per the manufacturer's
recommendations and procedures.
ROPE INSPECTION
57 Frequent Inspection
A.All running ropes in service should be visually
inspected once each working day. A visual inspec-
tion shall consist of observation of all rope which
can be in use during the days operations. These
visual observations should be considered with
discovering gross damage such as listed below,
which may be an immediate hazard.
1.distortion of the rope such as kinking,
crushing, un-stranding, birdcaging, main
strand displacement, or core protrusion.
Loss of rope diameter in a short length or
unevenness of outer strands should be
replaced
2.general corrosion

3.broken or cut strands;
4.number, distribution and type of visible
broken wires. When such damage is
discovered, the rope shall either be
removed from service or given as
inspection.
B.Care shall be taken when inspecting sections of
rapid deterioration such as flange points, crossover
points, and repetitive pickup points on drums.
58 Periodic inspection
A.The inspection frequency shall be determined by a
qualified person and shall be based on such factors
as:
1.expected rope life as determined by
experience on the particular installation or
similar installations
2.severity of environment
3.percentage of capacity lifts
4.frequency rates of operation
5.exposure to shock loads
Inspection need not be at equal calendar
intervals and should be more frequent as the
rope approaches the end of it's service life.
This inspection shall be made at least
annually.
B.Periodic inspection shall be performed by a desig-
nated person. This inspection shall cover the entire
length of the rope. Only the surface wires need be
inspected. No attempt should be made to open the
rope. Any deterioration results in appreciable loss of
original strength, such as described below, shall be
noted and determination made as to whether use of
the rope would constitute a hazard: points listed
above reduction of rope diameter below nominal
diameter due to loss of core support, internal or
external corrosion, or wear of outside wires;
severely corroded, cracked, bent, worn or improp-
erly applied connections;
C.Care shall be taken when inspecting sections subject
to rapid deterioration such as the following:
1.sections in contact with saddles, equalizer
sheaves, or other sheaves where rope travel
is limited
2.sections of the rope at or near terminal ends
where corroded or broken wires may
protrude
ROPE REPLACEMENT
59 No precise rules can be given for determination of the
exact time for replacement of rope, since many
variable factors are involved.
Continued use in this respect depends upon
good judgement by a designated person in
evaluating remaining strength in a used rope
after allowance for deterioration disclosed by
inspection. Continued rope operation depends
upon this remaining strength.
60 Conditions such as the following shall be reason for
questioning continued use of the rope or increasing
the frequency of inspection:
A.in running ropes, six randomly distributed broken
wires in one lay or three broken wires in one strand
in one lay
B.one outer wire broken at the contact point with the
core of the rope structure and protrudes or loops out
of the rope structure. Additional inspection of this
section is required
C.wear of one third of the original diameter of the
outside individual wire
D.kinking, crushing, birdcaging, or any other damage
resulting in distortion of the rope structure
E.evidence of any heat damage from any cause
F.reduction from nominal diameter of more than 1/64
in. (0.4mm) for diameters up to and including 5/16
in. (8 mm), 1/32 in. (0.8 mm) for diameter 3/8 in.
(9.5 mm) to and including 1/2 in. (13 mm), 3/64 in.
(1.2 mm) for diameter 9/16 in. (14.5 mm) to and
including 3/4 in. (19 mm). 1/16 in. (1.6 mm) for
diameter 7/8 in. (22 mm) to and including 11/8 in.
(29 mm), 3/32 in. (2.4 mm) for diameters 11/4 in.
(32 mm) to and including 11/2 in. (38 mm)

G.In standing ropes, more than two broken wires in
one lay in sections beyond end connections or more
than one broken wire at an end connection.
H.Replacement rope shall have a strength rating at
least as great as the original rope furnished or
recommended by the crane manufacturer. Any
deviation from the original size, grade, or construc-
tion shall be specified by a rope manufacturer, or a
qualified person.
61 Rope not in regular use: all rope which has been idle
for a period of a month or more due to shutdown or
storage of a crane on which it is installed, shall be
given and inspection in accordance with above infor-
mation before it is placed in service. This inspection
shall be for all types of deterioration and shall be
performed by a qualified person.
62 Inspection records
A.frequent inspection- no records required
B.periodic inspections- in order to establish data as a
basis for judging the proper time for replacement, a
dated report condition at each periodic inspection
should be kept on file. This report shall cover
points of deterioration listed above.
ROPE MAINTENANCE
63 Rope should be stored to prevent damage or
deterioration.
64 Unreeling or uncoiling of rope shall be done as
recommended by the rope manufacturer and with
care to avoid kinking or inducing twist.
65 Before cutting a rope, seizing shall be placed on each
side of the place where the rope is to be cut to prevent
unlaying of the strands. On pre-formed rope, one
seizing on each side of the cut is required. On
non-preformed ropes of 7/8 in. (22 mm) diameter or
smaller, two seizings on each side of the cut are
required, and for non-preformed rope 1 in. (25 mm)
diameter or larger, three seizings on each side of the
cut are required.
66 During installation care should be exercised to avoid
dragging of the rope in the dirt or around objects
which will scrape, nick crush or induce sharp bends
in it.
67 Rope should be maintained in a well-lubricated
condition. It is important that lubricant applied as a
part of a maintenance program shall be compatible
with the original lubricant and to this end the rope
manufacturer should be consulted. Lubricant applied
shall be the type which does not hinder visual inspec-
tion. Those sections of rope which are located over
sheaves or otherwise hidden during inspection and
maintenance procedures require special attention
when lubricating rope. The object of rope lubrication
is to reduce internal friction and to prevent corrosion.
68 When an operating rope shows greater wear or well
defined localized areas than on the remainder of the
rope, rope life can be extended in cases where a
section at the worn end, and thus shifting the wear to
different areas of the rope.

So many variable factors can cause the
deterioration of wire line cable that it is not
possible to determine a definite life expectancy.
Some of these factors are:
1.Load being handled.
2.Corrosive conditions.
3.Maintenance of the unit.
A.Keep the sheaves turning freely
B.Maintain tension on cable to insure
proper spooling
C.Avoid kinks in cable
D.Avoid abrasive action and contact with
sharp corners
4. Frequency of use.
Auto Crane units, up to 2,400 pound ratings, use
3/16 inch diameter galvanized pre-formed 7 x 19
aircraft cable. This cable has a working strength,
when new, of 4,200 pounds. It is recommended
when 1,200 pound loads are exceeded to use a two
part line with a traveling block. This will ensure a
3.5 to 1 safety factor when the cable is new.
Keeping the above factor of safety in mind and
knowing the kind of loads that will be handled, the
user can determine by inspection of the cable as to
when it should be replaced.
Items to look for while inspecting the cables
are:
1.Broken strands.
2.Kinks and flattened sections.
3.Corrosion and abrasion.
LIFE OF WIRE LINE
WIRELIF 10/98
1-6.0.0
WIRE LINE LUBRICATION
Lubrication of the wire line serves two
important purposes: (1) helps to prevent
corrosion; (2) lubricates the cable strands to
reduce wear due to flexing and abrasion caused
by contact with the sheaves, rollers, and cable on
the drum.
PREPARATION:
Remove rust and foreign matter with a wire brush
and wipe clean. Be sure cable is dry.
APPLICATION:
Method 1: A light weight motor oil may be used
by dipping a brush into the lubricant and applying.
In some cases, a rag or piece of sheepskin is
dipped in the lubricant and used to swab the
lubricant on to the rope.
Method 2: A heavier lubricant such as a grease
gun lubricant may be used by applying with hands
while wearing leather gloves. (Leather gloves are
preferred to canvas because of greater protection
and less penetration of the grease)

Maintenance of Auto Crane unit batteries differs very
little from the generally prescribed maintenance of any
lead acid battery. All batteries must be kept properly
charged, properly filled with water, and relatively
clean.
Keep Properly Charged
Many things affect the proper charge to a battery, such
as:
1 Regulator settings
2Proper tightness of belts on the alternator
or generator
3Good, clean connections of all cables
and wires at the following places:
A. Battery
B. Regulator
C. Starting motor
D. Alternator or generator
E. Ground connections (most important)
It is of extreme importance to keep the battery as fully
charged as possible without overcharging, especially
when vehicles are left outside for extended periods in
extremely cold climates. A battery can freeze.
Freezing points for various specific gravities of acid are
as follows:
Specific Gravity Freezing Temp.
(Corrected to 80ºF) Degrees F.
1.280 -90ºF
1.250 -62ºF
1.200 -16ºF
1.150 5ºF
1.100 19ºF
As shown, a half-charged battery (about 1.200 specific
gravity) cannot stand for any length of time at 20ºF or it
will freeze.
The main reason for keeping the battery as fully
charged as possible without over-charging is to ensure
that power is available even though the vehicle has been
standing for some time.
Keep Properly Filled with Water
The battery should always be properly filled with water.
If the electrolyte level is allowed to fall below the top of
the plates, the results become threefold:
1 The exposed portion of the plate will become
sulfated.
2The portion of the plate exposed is not usable.
3That portion of the acid remaining becomes more
concentrated and may cause more rapid
deterioration of the remaining parts of the battery.
Keep A Relatively Clean Battery
The battery should be kept clean. Batteries filled with
acid and which are not in use self-discharge to a limited
degree because of the nature of the materials within the
battery. If dirt is allowed to collect on the top of the
battery (and this dirt absorbs moisture) and electrical
path can be set up between the various terminals of the
battery and the ground. Once such a path has been
established, the self-discharge of the battery is
accelerated. This also accelerates corrosion of the
battery cables at the terminals.
Periodic Maintenance is Needed
A definite program of periodic maintenance of all
batteries should be conducted on a regular basis.
Periodic maintenance includes:
1 Checking belts for tightness on the charging
equipment
2Checking battery electrolyte levels
3Checking cables for good connections
4Cleaning where corrosion is apparent
When corrosion is cleaned off, the cable terminals and
battery terminals should be coated with a light coating
of petroleum jelly before they are replaced. When
terminals are cleaned, the top of the battery should be
cleaned with a mild solution of soda water.

Low Maintenance Batteries
(Maintenance Free)
Low maintenance batteries should not be used on
Auto Cranes or trucks equipped with Auto Cranes.
The batteries are not designed for "deep" discharge.
Testing Your Battery
If the condition of the battery is in question, it should be
removed from the vehicle, taken to the shop, and
allowed to reach room temperature. It should then be
recharged until specific gravity readings taken at
one-half hour intervals. If the specific gravity readings
are fairly uniform, the battery should be checked with a
high rate tester. Use the tester in accordance with the
manufacturer's instructions. The high rate tester is the
best method to test a questionable battery.
If, after charging, it is noted that the specific gravity
reading of one cell is 30 points less than any of the
other cells, it may be assumed that the cell is bad and
that the battery should be replaced. If all cells are
uniform but not up to full charge, a low rate of charge
should be attempted for an extended time. This usually
will recover a badly sulfated battery.
Replacing a Battery
If it is necessary to replace a battery, and a dry charge
battery is used, the following procedure applies:
1 Fill the battery with electrolyte of the proper
specific gravity.
2Place the battery on charge according to the
manufacturer's instructions.
It is essential that the second step above be followed to
ensure that the battery going on the vehicle is fully
charged.
It is also very important that the battery hold-downs be
checked periodically to ensure that the batteries are
properly positioned to avoid vibration problems,
breakage of cables or terminals. Care must be taken to
avoid cracking or breaking containers or covers by
tightening hold-down fixtures excessively. They also
must not be so loose that breakage results from a
hold-down that is too loose.
