Nexen TSE spring engaged safe brake for emergency braking

TSE spring engaged brake is a kind of safe air friction brake. Handong made HABB model spring applied air release brake can well replaced it. 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. 

HABB HDBB model normal braking brake, its cylinder and installation frame is separated. Installation frame is fixed on flange plate stably. 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.

There is one important point that as installation frame is fixed on flange plate, so when supplying air source, this air cylinder will be back to flange plate direction, so it needs to save a safe certain distance for it, in case of cylinder crashes to flange plate and damaged.

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, HAB--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.
