FOREWORD
Crysteel’s LoBoy hoists have been designed for use on single-axle trucks with cab-to-axle dimensions of
60 to 150 inches for use with bodies of 8 through 18 feet in length and on tandem axle trucks with cab-to-
tandem center dimensions of 102 to 126 inches for use with bodies from 14 to 18 feet in length. Bodies
normally used with these hoists are grain bodies and platforms. This manual contains the information
needed for the proper installation and operation of these hoists.
These instructions are for installing and maintaining all models of LoBoy hoists. With proper installation,
use, and regular maintenance, Crysteel’s LoBoy truck hoists will give many years of trouble free service.
When ordering parts, be sure to give serial number of hoist and cylinder. The serial number of the hoist
is stamped into the hoist frame near the base end of the cylinder. The serial number of the cylinder is
stamped on the barrel of the cylinder near the base. For future reference, copy these numbers NOW in the
space provided above. Order parts by number and description as given in the parts listing in this manual.
1. Engage PTO from cab and adjust engine speed to fast idle.
OPERATIONANDUSE
SOMEDO’SANDDON’TSFORSAFEANDLONGSERVICE
1. Usetheproperhydraulicuid.KEEPITCLEAN.Remembertochangeitregularly.
2. ALWAYS operate the hoist from inside the cab of the truck.
3. If the hydraulic hose connections are correct, the hoist should raise when the hoist control
lever is pulled back, hold when the lever is in the center detent, and lower when the lever
is pushed forward.
4. To raise the hoist, pull the control lever back. To hold the body in a raised position, place
the control lever in its center detent position. To lower the hoist, push the control lever
forward.
5. ALWAYS return the hoist control lever to its center detent position after each use.
6. Whenthehoistcylinderreachestheendofthestroke,oilwillowthroughtheautomatic
bypass valve built into the piston inside the cylinder and return to the reservoir.
7. It is advisable to run the PTO to “power down” or lower the hoist because this will act as
an hydraulic lock to hold the hoist in the lowered position. It is not necessary to do this,
however,becausethereservoirhassucientcapacitywhetherornotthehoistispowered
down.Youwillbenetfromtheadvantagesofthedoubleactinghoistonlyifyoupower
down.
8. To make use of the hydraulic lock feature, place the hoist control lever in the center hold
position after the hoist is powered down. This places the pressure on the valve, where it
belongs, not on the pump.
9. DO NOT LEAVE THE PTO IN GEAR WHILE TRANSPORTING. THIS CAN CAUSE
SEVERE DAMAGE TO THE PTO OR HYDRAULIC PUMP.
10.Thehydraulicsystemshouldbedrained,ushedandrelledwithproperhydraulicuid
atregularintervals.CAUTION:NEVERusehydraulicBRAKEFLUIDinthehydraulic
system.
11.Afteraddingorreplacingthehydraulicuid,cyclethehoistseveraltimestoremoveair
from the cylinders and hydraulic hoses.
2. Lubricateallgreasettingsevery100cyclesoreverytwomonths.Infrequentorinsu-
cient lubrication will cause hoist failure and possibly injury or death.
3. ALWAYS carefully block up the body, using the body prop, before working under it.
4. Do not “race” the engine when unloading.
5. Do not load the hoist beyond its capacity.
6. DO NOT tamper with the hydraulic relief valve. This will void the warranty. It can cause
severe damage to the hoist and cylinder.
7. Never leave the PTO in gear while transporting. It could ruin the hydraulic pump, the PTO
or the transmission.
8. Checkallboltsandttingsregularly.Keepthemtight.Seetableonpage4fortorqueval-
ues.
9. Alwaysoperatehoistonarmandlevelsurface.
10. Always make sure area around truck is clear and safe for hoist operation and dumping.

LOCATE AND INSTALL REAR HINGE
On single-axle trucks, the rear hinge must be located as close as possible behind the rear spring hanger.
This will be 32 to 36 inches behind the center of the rear axle. On tandem axle trucks the center of the rear
hinge should be located 42 to 50 inches behind the center of the rear tandems. Mark the rear of the truck
frame for notching as shown in Figure 1. Notch the truck frame as marked. Make sure the rear hinge is
squarewiththetruckframeandatthecorrectheight.Thetopsurfaceoftherearhingebracketshouldbe
ushwiththetopoftheanglemountingbracketsofthehoistframeasshowninFigure1.Securelyweld
the rear hinge to the truck frame. Cap the ends of the truck frame under the rear hinge. Weld the capping
plates to the ends of the truck frame and to the bottom side of the rear hinge angle.

LOCATEHOIST
Determine where to mount the hoist on the truck. Please refer to the chart in Fig. 4 for the relationship
between dump angle and “D” dimension. Measure forward from the center of the rear hinge pin and mark,
on the truck frame, the location of the front crosstube of the hoist frame. Place the hoist on the truck frame
and clamp the hoist pivot pads to the truck frame. The back end of the hoist must be supported by a cross-
member in the truck frame. The top of this crossmember may be up to 1” below the top of the truck frame.
The “CM” dimension shows the location for this crossmember. Make sure the hoist frame is centered on
andsquarewiththetruckframe.
Ifdesired,thehoistcanbeturnedendforendfora‘Reverse’mount.Thisdoesnotaecttheliftingcapac-
ity.
WARNING! LOCATING THE REAR HINGE FARTHER BACK THAN
RECOMMENDED MAY CAUSE UNDUE STRESS IN THE TRUCK FRAME,
AND MAY CAUSE INSTABILITY DURING THE LIFTING CYCLE!

MOUNT HOIST FRAME
Thehoistpivotpadsmustrestatonthetruckframe.Ifthehoistpivotpadssitonrivetheadsinthetruck
frame, either move the hoist or drill holes in the pivot pads to clear the rivets. On the driver’s side, clamp
the hoist mount/prop pivot the lower hoist pivot pad and to the outside of the truck frame. On the passen-
ger side, clamp a hoist mounting angle to the lower hoist pivot pad and to the outside of the truck frame.
Mark the truck frame for drilling. See Figure 5.
CAUTION: BE CAREFUL OF BRAKELINES, WIRING, ETC. INSIDE THE
TRUCK FRAME WHEN DRILLING THE TRUCK FRAME.
Drill 21/32 diameter holes in the truck frame using the hoist mounting angles as guides. Bolt the prop
pivot and mounting angle to the truck frame using 5/8 x 2 hex bolts and hex lock nuts, tightening to 180 to
190 lb-ft. Securely weld the lower hoist pivot pads to the mounting angles. DO NOT WELD THE HOIST
PIVOTPADSTOTHETRUCKFRAME!Removetheclamps.

reservoir mounting angles to the reservoir/valve assembly so the exposed end of the valve spool is toward
the cab (See Fig. 7). This makes it much easier to connect the valve control cable to the valve. Place this
assembly against the outside of the truck frame on the same side as the pump. Mark the truck frame for
drilling using the mounting angles as guides. Make sure there is enough clearance for hot exhaust pipes.
THE ENGINE EXHAUST MUST NEVER BLOW DIRECTLY ONTO THE RESERVOIR/VALVE AS-
SEMBLY.

The reservoir/valve assembly should be mounted on the same side of the truck as the pump with the ex-
posed end of the valve spool toward the front. Bolt the mounting angles to the reservoir/valve assembly
using3/8x1capscrews,atwashersandhexlocknuts,tighteningto24to26lb-ft.Placethereservoir/
valve assembly inside the truck frame and raise it as high as possible. See Figure 5. (There is no drive line
to align and the reservoir should be higher than the pump for reliable performance.) Make sure there is
enough clearance for the truck drive line and hot exhaust pipes. THE ENGINE EXHAUST MUST NEV-
ER BLOW DIRECTLY ONTO THE RESERVOIR/VALVE ASSEMBLY. Clamp the mounting angles to
the truck frame and mark the truck frame for drilling using the pump mounting angles as guides.
INSTALL HOIST CONTROL
Mount the Hoist Control decal on the pedestal taking care to align the holes for the PTO cable and indicator
light. Temporarily assemble the valve control head to the pedestal using 5/16 x 2 1/2 machine screws and
hexnuts.Placethisassemblyontheoorofthecab.Thepedestalandvalvecontrolshouldangleforward.
This makes it convenient for the operator to pull the hoist control lever back to raise the hoist. Make sure
there is enough room to operate the valve control and gear shift lever and to adjust the seat. Check below
theoorforobstructionsandcablerouting.Relocatethevalvecontrolifnecessary.Marktheoorusing
the pedestal as a template and drill 11/32” holes for the mounting screws and a 3/4” hole for the control
cable. Assemble the control cable to the valve control head and assemble the valve control head and cover
to the pedestal using 5/16 x 2 1/2 machine screws and hex lock nuts. Insert the control cable through the
holeintheoorandmountthepedestaltotheoorusing5/16x1/2hexheadcapscrews,clampingplate
(undertheoor)andhexlocknuts.Makesurethevalvecontrolleverisinitscenterdetentposition.Keep
the control cable away from hot exhaust pipes and rotating drive shafts. The control cable should not have
any sharp bends or kinks in it (these will make the control harder to operate).
Install the 3/4” hex jam nut onto the valve end of the control cable and turn it past the threads. Insert the
end of the cable through the bonnet clamp. Install the bonnet onto the control cable and turn it past the
threads also. Install the 1/4” hex jam nut and terminal eye on the core rod of the cable; lock the terminal
eye to the core rod of the cable using the hex jam nut. Place the terminal eye in the slot of the valve spool;
insert the short pin through the valve spool and terminal eye and secure it in place with the `E’ ring. Thread
thebonnetontotheendofthecablesoitrmlytouchestheendofthevalve.(Donotover-orunder-tighten
the bonnet as either would move the valve spool out of its neutral position.) Remove two cap screws from
opposite corners of the seal retainer plate. Slide the bonnet clamp onto the bonnet and secure it to the valve
usingthe1/4x11/4capscrews,lockwashersandatwashers.Lockthebonnettothecableusingthe

NOTE: If the pump does not pump oil, pressurize the reservoir and engage the pump with the engine at
slow idle. Once the pump is working, release the pressure and install the breather cap.
For the B-5 (Bert) model hoist, fully raise and lower the hoist several times to remove air from the cylinder
and hoses. For C-8 (Charlie), D-9 (Daniel), D-10 (David), E-15 (Ernie), F-18 (Floyd) and H-25 (Henry)
hoist models, fully raise the hoist and hold the hoist control in the `RAISE’ position for 20 to 30 seconds.
Thiswillremovetheairthatisinsidethecylinder(s).Lowerthehoistandchecktheuidlevelintheres-
ervoir; the reservoir should be 2/3 full with the body down.
With normal use and working conditions the hydraulic oil should be changed annually. The breather cap
should be cleaned every time the hydraulic oil is changed. With heavy use or very dusty working condi-
tions the hydraulic oil should be changed more often.
ELECTRIC POWER UNIT MOUNTING - GENERAL
The electric power unit should be mounted close behind the cab, either inside or outside the truck frame.
After determining where to mount the power unit, bolt one mounting angle to the power unit using the
3/8 x 1 hex head cap screws, tightening to 24 to 26 lb-ft. (See Fig. 11.) Clamp the mounting bracket to the
truck frame. Clamp the second mounting angle to the truck frame so it supports the far end of the reservoir.
Insert a rubber pad between the mounting angle and the reservoir; and secure it in place with a tie strap.
Mark the truck frame for drilling using the pump mounting angles as guides.
CAUTION: BE CAREFUL OF BRAKELINES, WIRING, ETC. INSIDE THE
TRUCK FRAME WHEN DRILLING THE TRUCK FRAME.
Drill 17/32” holes in the truck frame and bolt the reservoir/valve assembly in place using 1/2 x 2 cap
screws and hex lock nuts, tightening to 90 to 100 lb-ft.
For rated performance, the voltage at the power unit must be a minimum of 12VDC. This should be mea-
sured between the large terminal of the start solenoid (where the battery cable is connected) and the power
unit base. NOTE: Grounding of the power unit is just as important as the installation of the positive battery
cable. It is easier to get a good ground by using a second battery cable.
Connect the large terminal on the motor start solenoid to the positive terminal on the battery with a #0
gauge battery cable. Connect the negative terminal on the battery to the grounding hole on the power unit
with a #0 gauge battery cable. See Figure 12. Check the voltage between the large terminal on the start
solenoid and the power unit base.

INSTALLBODYPROP
The body prop is designed and intended to support an EMPTY truck body in the raised position. Use of
the body prop permits service to be performed safely beneath a raised body. It is mounted on the outside
of the truck frame on the drivers side.
1. Raise the body half way up and brace it securely before beginning installation.
2. Install the prop arm on the hoist mount / prop pivot with a 1/4 x 3 roll pin. Raise the body
prop arm to the vertical, free standing position. Place the body prop bracket in the prop
arm saddle. Lower the body so the bottom of the longbeam body prop bracket is between
1/2” and 1 1/2” up from the bottom of the body longbeam. For bodies with angled long-
beams, keep the longbeam body prop bracket as low as possible. Securely weld the bracket
to the longbeam.
3. Tooperatethebodyprop,raisethebodytothedesiredheight,shutoallpower,raisethe
prop arm to a free standing position. Lower the body slowly until the body prop bracket
contacts the prop arm saddle.
4. To place the body prop in the storage position, raise the body to clear the body prop saddle,
lower the body prop to the storage position and lower the body.
5. When mounting the passenger’s side prop, replace the hoist mounting angle with the hoist
mount/prop pivot. Prop the body in the raised position using the driver’s side prop. This
will ensure that both props are supporting the empty body.
An optional passenger’s side prop kit is available.

CAPACITY FORMULA
The capacity of the LoBoy truck hoists can be calculated using the following steps.
1. Measure the distance, in inches, from the center of the rear hinge to the center of the body. Call
this “A”.
2. Measure the distance, in inches from the center of the rear hinge to the forward crosstube on the
hoist. Call this “D”. (See Figures 2, 3 & 4 for “D” dimensions for the various models.)
3. For Model B-5 (BERT), multiply “D” by 3.87.
For Model C-8 (CHARLIE), multiply “D” by 6.05.
For Model D-9 (DANIEL), multiply “D” by 7.32.
For Model D-10 (DAVID), multiply “D” by 6.16.
For Model E-15 (ERNIE), multiply “D” by 8.87.
For Model F-18 (FLOYD), multiply “D” by 8.75.
4. Divide the result of Step 3 by “A”. This is the capacity in tons for an evenly distributed load
(over the whole length of the body) and includes the weight of the body.
