Brake designs of boom lift platform

Support brake is also named work brake, it is the kind of brake used in all types of boom lift platform designs.In the lifting operations, starting and braking frequencies are very high, that makes brake an indispensable part.

Under normal circumstances, it helps holding the load; when accident occurs, it is one high level safety insurance part. In most applications, boom lift platforms are designed with one single support brake, its safety factor is enough for most work requirements, but safety risk still exists: once the brake is down, the lift equipment would not be able to stop normally, and the safty insurance is lost; the safety insurance is limited, when transmission chain jams or breaks, although the brake is good, the boom lift platform would be out of control. In the lifting work of molten metal, dangerous and other special goods, safety is a hidden risk for lifting equipment with one brake.

As a working device, support brake has the functions of stopping and decelerating (when speed adjusting system is at zero speed braking state, decelerating is proper operation). Support brake is used to make the load in the floating state when lifted up. As the safety insurance device, when electronic safety switch is on, support brake effect in both slowing down the speed and support braking.
