Why Emergency Disc Brakes?
Purpose: the purpose of Emergency Braking System is an abortion of load movement (i.e. ladle with molten metal) during lowering after a failure or interruption of kinematic chain between a respective drive
Lifting in hoist applications is carried out by electric motors through the clutches and gearboxes to winding drum. These motors are decelerated by the brakes but the clutches and gearboxes have no brakes installed. After clutch or gearbox failure a lifting drum can get loose and free fall will occur. It is necessary to install emergency braking system to preclude a free fall from occurring and avoiding a catastrophic failure.
How it Works:
Operation of Emergency Braking system is based on the principle of continuous monitoring of instantaneous revolutions of winding drum and other major components. It provides an early recognition of hazardous conditions of monitored monitored components and subsequent prevention of emergency situation occurrence by engagement of Emergency braking system brakes. Ultimately, a load suspended on lifting cables is stopped.
