Do not overload the crane.
-
When operating along obstacle-free paths, the hook, lifting device, or bottom surface of the load must remain at least 2 meters above ground level. When crossing obstacles, the load must clear the obstacle by at least 0.5 meters
-
For loads under 50% of rated capacity, both lifting mechanisms may operate simultaneously. For loads exceeding 50% of rated capacity, only one mechanism may operate.
-
.For bridge cranes equipped with main and auxiliary hooks, do not simultaneously raise or lower both hooks (except under special circumstances).
-
Welding or hammering on suspended loads, or working beneath suspended loads, is prohibited (except when properly supported).
-
Inspection or maintenance work may only be performed after power has been disconnected and a “Do Not Operate” sign is displayed on the power switch. If live work is unavoidable, implement safety measures and assign dedicated supervision.
-
Do not throw objects from the vehicle indiscriminately.
-
Regularly inspect limit switches and interlock protection devices.
-
Do not use limit switch impact as a stopping method.
-
Do not lift or lower loads when hoist brakes malfunction.
-
Do not operate the hoist above personnel or equipment.
-
When welding any part of the crane, use a dedicated ground wire; do not use the crane body as a ground.

-
Cranes must not collide with each other; using one crane to push another into operation is strictly prohibited.
-
When lifting heavy objects, molten metal, explosives, or hazardous materials, first slowly raise the load 100–200 mm off the ground to test brake reliability.
-
Maintenance and inspection lighting must operate at voltages below 36V.
-
All electrical equipment enclosures on bridge cranes must be grounded. If trolley rails are not welded to the main girder, grounding measures must be implemented.
