Friction to slow or stop the speed of machinery and movement
- Apr 12, 2018 -

The brakes work by using friction to reduce or stop the speed of mechanical and moving masses.

The brake can be mounted on either shaft of the crane drive, but to reduce its size, it is best to fit as much as possible on the first drive shaft of the drive that is subject to minimum torque. We firmly mount a brake disc on the shaft that can rotate with the shaft at the same time, and the parts where the base is fixedly connected are pressed against it with a certain force due to the relative movement between the two. The frictional force that causes the brake to act, change the magnitude of this friction force, can obtain the required braking effect.

The hoisting mechanism of all double beam cranes must be equipped with closed brakes. With the exception of friction clutches or dog clutches and mechanisms with friction drives, exceptions can be tolerated. Open brakes can be used, so items can be lowered in the braking state.

All electric double-girder cranes and operating mechanisms with electric cabs for operating cabs or double-girder cranes as well as the operating mechanism of electric double-girder cranes must be equipped with closed brakes that act on their own when the current is switched off. .

When double-girder cranes are driven by a prime mover to drive several sets of mechanisms, each set of mechanisms must be individually equipped with its own brakes.

The mechanism used to lift and move the molten metal must have two brakes on each group. In operating electric blocks, a load-bearing brake can be installed as a second brake.
