Heavy-Duty Telescopic Crane Owner’s Manual
Unstowing the Crane:
To unstow the crane and prepare it for a lift:
• Winch down slightly.
• Raise the boom high enough to clear the boom rest and any other obstructions from the chassis.
• Rotate the crane until it clears the side of the truck body.
• Lower the crane boom down far enough so that the snatch block is within comfortable reach.
• Winch down to create slack in the wire rope and unhook the snatch block.
Attaching the load:
• Position the crane with the hook centered directly over the load avoid side loading.
• Attach the load to the hook by means of slings or other approved devices.
•
Never use a sling bar or anything larger than the hook throat that could
prevent the hook latch from closing. This would negate the safety feature.
• Maintain a minimum of 3 full wraps of wire rope on the winch drum at all times.
•
Do not wrap the wire rope around the load.
Lifting the load:
Lift the load slightly off the ground to check the safety of the cargo. Consider the following:
• Make certain that the stabilizers are positioned on flat, stable ground.
•
Never exceed manufacturer’s load charts and ratings. These ratings are
based on the machine’s hydraulic, mechanical, and structural design rather
than stability.
• Never perform a lift that can induce a dynamic force greater than the capacity of the crane.
• It is the responsibility of the operator to know the weight of both the rigging and the handled
load to avoid overloading the crane. Do not rely on the overload device to determine maximum
rated loads. If the crane is picking more than the maximum rated load, the overload protection
device may be malfunctioning. Discontinue use immediately and contact Stellar
