High quality safe spring locking brake for entertainment equipment

HABB model spring applied air release brake is with high quality, it is normal braking, so it is also called safe brake. Its working is reverse of NAB air positive brake. In normal status, the brake is braked by springs, after supplying air pressire, brake is released. It is suitable for preventing accident and emergency braking. 

If air is intercepted, it stops by braking springs. If air is supplied, it is released. If supply air pressure from flow control valve, cylinder will be move, pan head screw and piston rack rotating together, compressing braking springs, friction plate and bushing disc separated, brake released. If exhausting air pressure, springs compress piston rack, friction plate touched with bushing disc, brake linked.

This normal braking brake is also can produce high braking force from 59N.m to 451N.m. Details of it as below:

From above technical data sheet, we can acknowledge that this brake is also bore shaft brake, its bore diameter is 25-75mm. Different model brake, its braking force is different, too. There are four models of this HABB spring engagement brake, including HABB-5, HABB-10, HABB-20 and HABB-40.

This HABB model brake is also a kind of friction type brake, so it can be rotating in fast speed, from 1800r/min to 3600r/min. On the other hand, because its friction plate is non-asbestos, so it is suitable for fast connecting and fast rotating.
