Suggestions for Safe Operation

DO the following:

Read and comply with the guidelines set forth in this Owner’s Manual. Keep 

this manual, and all labels attached to the crane, readable and with the 

equipment at all times. Contact Thern, Inc. for replacements.
Check lubrication before use.

Install the wire rope securely to the winch drum.

Keep at least 4 wraps of wire rope wound on the drum at all times, to serve as 

anchor wraps. With less than 4 wraps on the drum the wire rope could come 

loose, causing the load to escape.
Keep hands away from sheaves, gears, wire rope, and other moving parts.
Disconnect electric power before servicing the equipment.
Keep all unnecessary personnel away from crane while in operation.
Keep out of the path of the load, and out of the path of a broken wire rope 

that might snap back and cause injury.

DO NOT do the following:

Do not lift people, or things over people. Do not walk or work under a load or 

in the line of force of any load.
Do not exceed the load rating of the crane or any other component in the 

system. To do so could result in failure of the equipment.
Do not use more than one crane to move a load that exceeds the load rating of 

a single crane. A shift in load weight could overload the equipment.
Do not use damaged or malfunctioning equipment. To do so could result in 

failure of the equipment.
Do not modify the equipment in any way. To do so could cause equipment failure. 
Do not wrap the wire rope around the load. This damages the wire rope and 

could cause the load to escape. Use a sling or other approved lifting device.
Do not operate the crane with guards removed or improperly installed.
Do not divert your attention from the operation. Stay alert to the possibility of 

accidents, and try to prevent them from happening. 
Do not jerk or swing the load. Avoid shock loads by starting and stopping the 

load smoothly. Shock loads overload the equipment and may cause damage.
Do not use the crane and winch components for any use other than for their 

original intended function.
Do not use the crane to drag or pull loads. This will create side pulls, which 

could damage the equipment or cause the load to tip.

Do not leave a suspended load unattended. Place the load on the ground if it 

must be left unattended.

Do not adjust the winch brake with the load suspended.
Do not operate or apply loads without all pins securely in place.
Do not adjust the sheave position or boom angle while the crane is loaded.
