Classification of brake types of crane

Crane brake is a part with the function of adjusting speed is the height of the steering wheel while lifting machinery and equipment. The brake brake has a role to ensure safety and support the operation of the crane, so what kind of crane is there? What are their characteristics? The following article will answer those questions to help you.

Brakes of crane

Classification according to the operating principle

Brakes have two types: closed brake and open brake. Closed brakes only work when the devices are opened and operating. Open brakes are the type of brakes used under the influence of external forces.

Assign brake type according to the structure

There are 4 types of brakes used for crane including brake pads, brake brakes, brake and belt brake.

Most of the current lifters are mainly used as brake pads, the didemr feature of this brake is to have two brake pads symmetrically with the brake wheel, which helps to brake the two torque in two directions. rotate the same, do not change the shaft shape.

The torque from the cheek brake is in the form of friction of brake wheels and brake pads, similar to cheek brake on bicycle wheels. The driving force of the cheek brake is transmitted by motor, either by electric or pneumatic ...

The brake pads themselves work on frictional forces so the brake pads work long and stable, need to choose a brake with a high coefficient of friction, withstand good abrasion and heat resistance. To secure the brake pads, people use brass or aluminum rivets to close half the thickness of the brake pads to make sure the brake pads are firm.

Belt brake is also a type of brake that is used a lot because the structure is very simple. But often only for rotary movement because safety is not high because they suffer very poor friction generated from brake belts and brake wheels.

When to replace the brake of crane

• When the brake pads are worn out, worn to the part of the screw used to secure the brake pads, or one of the brake pads wears unevenly, the brake pads must be replaced. There are also cases where the brakes are cracked, the brake pads are not 100% exposed.
• For belt brakes, if the gap between the brake belt and the brake wheel is more than 2mm or the brake has an open track, replace the other brake belt. When the brake belt is worn out too much, up to 50% must be changed immediately.
