To serve the process of using and maintaining the crane, the brake is one of the parts that are always concerned because it directly affects the operating process and safety during operation. So what types of crane brakes are there? And when do you need to replace the crane brake? Let's refer to offline!
Currently, on the market, many types of crane brakes are put into use to replace maintenance for cranes.
When you need to replace the crane brake?
- According to the principle of operation, crane brake is divided into 2 types, that is closed brake and open brake:
A closed brake is a type of brake that is always working.
+ Open brake is a type of brake that only works when there is an external force.
- By structure: Crane brake is divided into cheek brake, belt brake, disc brake, and clutch brake. In there:
+ Brake pads: this is the most used type of brake in crane machines
+ Belt brake: simple structure, braking torque is generated by the friction force between the brake belt and the brake wheel, so the level of braking is low.
The crane brake is a very important detail in the safe operation of the crane. The brake keeps the load from drifting when the crane is not in operation. A safety brake system is a system that opens and closes rhythmically and accurately at the right time, short and accurate opening and closing time will make the crane lifting motor not overloaded and the brake pads at the same time. , the crane brake wheel also reduces unnecessary wear and tear. However, in some cases, it is necessary to replace and maintain the brakes so that the whole crane system can be operated safely, such as:
- The first case: the brake pads are worn unevenly, worn to the screw holding the brake pads, and need to be replaced to ensure safety.
- The second case: when there is a gap on the brake belt, the clearance between the brake belt and the brake wheel is less than 2mm or more than 4mm, and when the brake wheel is worn more than 30% of the original thickness of the brake wheel. When the brake belt is worn more than 50% of the original thickness, then the brake only works the brake belt only contacts the brake wheel and the brake wheel wears unevenly.
When do you need to replace the crane brake?
After using the crane, regularly clean the brake system as well as other parts to ensure the machine is always clean, apply the right lubricant to limit the corrosion taking place with the brake system, and regularly maintain and maintain the crane to ensure the machine is more durable.
Above is some information about the crane brake and the case of replacing the brake to ensure the safety of the operation process that we want to send to you. Hope this information is useful for your work. Wishing you a productive day!
