The principle of the brake is to cut off the inertia kinetic energy of the moving parts through the friction pair, to produce friction heat energy consumption, to achieve the purpose of braking.
Its structural characteristics are that one part of the friction pair is connected with the fixed member and the other part is connected with the rotating shaft of the braking mechanism.
When the friction pair is separated, the braking action is released and the mechanism can work normally.
Crane brake mainly has the following three functions:
(1) support: in the lifting mechanism, keep the lifting weight static in the air;
In the luffing mechanism, the arm is kept in a certain position and remains stationary.
It has the function of windproof and anti-skid to outdoor track crane.
(2) stop action: make the movement of the body quickly in a certain time or a certain journey to stop.
(3) drop weight effect: the braking force and gravity balance, so that the movement of the body with a stable speed down.
Because the crane is an important lifting equipment, during the lifting process, whether the brake can work normally, to protect the crane brake safety, it is particularly important, so we hope that the majority of customers to buy a large factory brake, feel at ease.
