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.
It is the further responsibility of the installer to comply with the OSHA

(C) (1). In applications, where the rotation of the load is hazardous, a tag or
restraint line should be used, (ref. OSHA 1910.180(h)(3)(xvi)). To reduce the potential for the load
to rotate or rope twist, operate at minimal boom angles and extension.
Do not attempt to lift or drag a load from the side! The boom can fail far
below its rated capacity.
Do not weld, modify, or use unauthorized components on any Auto Crane
unit! This will void any warranty or liability. Also, failure of the crane may
result.
Failure to correctly plumb and wire crane can cause inadvertent operation
and damage to crane and/or personnel!
Auto Crane Company remote controlled cranes are not designed or intended
for use for any applications involving the lifting or moving of personnel. Any
such use is considered to be improper and the seller shall not be responsible
for any claims arising from such use. There is no implied warranty or responsibility for such uses.

Safety Tips and Precautions 1

4 HC-10 NEXSTAR III
Keep this manual with the crane at all times.
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
specically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 crane owners, equipment managers, and supervisors also read this manual.
Auto Crane has incorporated several safety features in the crane for your protection.
For your convenience the overall dimensions of the crane are included on the General
Dimension Drawing. Rotation and turning radius are also listed on that drawing.
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.
AutoCraneCompanyissuesalimitedwarrantycerticatewitheachunitsold.Seelastpagefor
warranty.
The cranes are attached to your 12-volt truck electrical system. The crane is another highly
efcientAutoCraneproduct.Theuseofamaintenance-freebatteryisnotrecommended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 500 cold cranking amp battery. These
specicationsshouldbeconsideredminimum.
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, misused,
overloaded or otherwise damaged by inexperienced persons trying to operate the equipment
without reading the manual.

Load Chart 4
All load ratings are based on crane capacity, not the vehicle stability. When
lifting a heavy load, the weight can create enough tipping moment to
overturn the vehicle. DO NOT USE the overload shutdown device to
determine maximum rated loads, if the crane is equipped with this type of
device.
Always comply with load chart capacities.

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
conguration.
C. Know the weight of the rigging and deduct from the load rating to prevent overloading
the crane.
D. When loads that are not accurately known are to be lifted, the person responsible for the
job shall determine the weight of the load does not exceed the crane rated load at the
radius at which the load is to be lifted.
2. Attaching the load.
A. Ensure the load is properly attached to the hook by means of slings or other devices of
sufcientcapacity.
B. Ensure the vehicle is in a level position when loading or unloading.
C. Hoist rope shall not be wrapped around the load.

A. The crane is level and, where necessary, the vehicle/carrier is blocked properly.
B. The load is well secured and balanced in the sling or lifting device before it is lifted more
than a few inches.
C. Means are provided to hold the vehicle stationary while operating the crane.
D. Before starting to lift, the hook shall be positioned over the load in such a manner as to
minimize swinging.
CAUTION

10 HC-10 NEXSTAR III
4. During lifting care shall be taken that:
A. There is no sudden acceleration or deceleration of the moving load.
B. 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.
C. Load, boom or other parts of the crane do not contact any obstruction.
D. Cranes shall not be used for dragging loads sideways.
E. This standard recognizes that telescopic 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.
F. The operator should avoid carrying loads over people.
5. When the crane is so equipped, the stabilizers shall be fully extended and set. Blocking under
stabilizers shall meet the requirements as follows:
A. Strong enough to prevent crushing.
B. Of such thickness, width and length as to completely support the stabilizer pad.
C. Firm footing under all tires, or individual stabilizer pads should be level. Where such a
footing is not otherwise supplied, timbers, cribbing, or other structural members to
distribute the load so as to not exceed allowable bearing capacity or the underlying
material should provide it.
