If the grab crane is close to the winch brake and the trolley is close to the terminal, the speed will slow down if it encounters the adjacent vehicle. The reverse brake cannot be used to replace the brake, the parking switch cannot be used to replace the brake, and the emergency switch cannot be used to replace the normal switch. Walk up and down the designated safe passage, special way or escalator. The rail ends of large vehicles cannot be operated except for inspection. Stop walking on the tracks of cars. It is not allowed to cross from one grab crane to another.


When the grab crane operates intermittently, it is not allowed to hang heavy objects in the air. When driving, there are still people on the ground. When the lifting load drops, please ring the bell to announce the warning. Don't hang it around your neck. The progressive load should not be too far from the ground. When lifting things together, the two bridges follow the instructions and adhere to the same speed. During operation, a certain distance should be maintained between the bridge cranes. The repair bridge crane should be placed in a safe place, cut off the power supply, and hang a warning sign of "stop braking". Fence shall be set up on the ground and the sign of "stop passing" shall be hung.
