Stellar® EC Series Crane Owner’s Manual
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.
• 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 Customer Service for support.
• Do not use a crane to lift personnel.
• Do not attempt to lift fixed loads.
Moving the load:
Ensure that the load is secure and balanced within the sling before moving. Consider the
following:
• Be sure that the crane is level and stable before moving the load.
• Always look for any changes to the surroundings since the job site setup. Be aware of
any new or missed overhead obstructions (branches, power lines, etc) and bystanders.
Use a signal person if necessary.
• Never operate the crane with personnel under any part the boom or
load. Do not extend or rotate a load over anyone. Never allow personnel to place
themselves under any part of the boom or load.
• Never leave a crane load suspended or unattended.
