Overhead cranes are crucial lifting devices in the manufacturing and construction industries. Operating overhead cranes requires strict adherence to safety and technical procedures to ensure work efficiency and safety for workers. Below is the basic operating procedure for overhead cranes.
Crane Inspection Before Operation
Step 1: Visually inspect the equipment and drive units under the ground and within the crane’s working range to ensure there are no abnormalities or obstructions.
Step 2: Open panel 1E1 -> Close the Aptomat to power supply the crane.
Step 3: Check all button EM.Stop (remote, pendant, panel 1JB1, panel 1JB2) to make sure it hasn’t been affected.
