What are the standards for the operation process of bridge cranes

What are the regulations during the operation of bridge cranes? For specific regulatory issues, let the editor from the bridge crane manufacturer take you to understand together.

Start up and trial lifting

Ring the bell or flash a warning before starting, confirm that there are no abnormalities, and then push the power switch.

Before lifting, run the equipment with no load and check if the braking system, limit switch, etc. are normal.

When lifting heavy objects, first lift them 100-200mm off the ground to confirm the stability of the brake, wire rope, and lifted object.

load control

Overloading is strictly prohibited. When approaching the rated load, a trial lifting test is required to verify stability.

When lifting liquid metal, explosive and dangerous goods, it is necessary to slowly lift and test the reliability of the brake.

The main and auxiliary hooks of the double hook crane are prohibited from lifting and lowering simultaneously, and only a single mechanism is allowed to operate when exceeding the rated load by 50%.

operational requirements

The height of the suspended object above the ground should be ≥ 2m, and an additional 0.5m should be raised when crossing obstacles.

Operate the control lever and buttons smoothly during operation, avoid violent movements, and prevent damage to equipment and personnel.

It is prohibited to use diagonal braces, lift objects over human heads, or directly process hanging heavy objects.

Strictly implement the "Ten No Lifting" principle, including situations where the command signal is unclear, overloaded, and the binding is not secure, and lifting is not allowed.

Signals and Communication

Command personnel must hold certificates and use unified gestures or walkie talkies for instructions.

The operator needs to maintain good communication with the commander to ensure the accuracy and safety of the operation.
