Braking Device Of Bridge Crane

Braking device of bridge crane

In order to adapt to the working needs of various bridge cranes and ensure driving safety, reliable mechanical brakes should be installed on all bridge cranes. Among the various mechanisms of the crane, the main functions of the brake are as follows:

Reducer: Stop the reducer of the running mechanism.

Operating brakes: Brakes allow the mechanism to operate at the required speed.

Maintenance braking: Braking can prevent the mechanism from losing its transmission device under the action of external forces such as load, gravity, wind, etc.

The selection of bridge crane brakes should follow three principles:

Standard principle: The braking device is a universal component product, and the product has been specified in accordance with the standard. Brakes should be selected according to my country's current standards. If domestic standard products do not meet the requirements, internationally advanced national product standards can be used. If domestic and foreign standard products cannot meet the requirements, try to choose products determined by domestic and foreign brake manufacturers. If the requirements are still not met, the person or professional organization will design according to regulations.

Mechanical matching principle: When selecting a brake, you must fully consider whether the brake specification (center height) is consistent or similar to the center height of the mechanical brake (motor center height when high-speed shaft braking, drum center height when low-speed shaft braking) .

Safety principle: When selecting braking and braking methods, the safety of various bridge-type hoisting mechanisms should be fully considered and matched with their safety requirements. If the quality of the bridge crane brake is not up to standard, it is easy to malfunction. When encountering problems, understand the reasons for crane brake failure and propose targeted solutions.

It is crucial to choose reliable 10 ton overhead crane protection devices. We have emphasized this repeatedly. For example, if the overload limiter fails and an operation error occurs, the entire overhead crane will be crushed, causing catastrophic consequences.
