Active Brakes
- hydraulic pressure applied
Active brakes are hydraulic pressure
applied and used for a range of different purposes, such as
stopping and holding. With a minimum air gap the response time can
be very short allowing for fast braking. The large brake pad area
reduces wear and lowers the brake disc temperatures and stress,
hereby extending the overall lifetime on the brake pads. Few moving
parts and easy maintenance mean reduced operation costs. In case of
leaking seals the drain ports collect the leaking oil and minimise
the risk of oil getting onto the brake disc hereby improving
safety.
A range of indicators are available as accessories and can be
fitted to the brake to detect and monitor the status of the brake
functions, such as: brake pad wear (when to replace) and brake
lining temperature.
There are two variations of the Fail-Safe brakes:
Dual-Action and Mono-Action.
Dual-Action
The Dual-Action brake consists of two caliper halves designed for
mounting on a bracket. As the only moving parts are the brake
pistons the Dual-Action brake is a very simple and reliable
brake.
Mono-Action
The Mono-Action brake is a combination of a three parts:
an active calliper half and a passive calliper mounted on a base
plate suitable for side mounting. The brake caliper assembly is
free floating on guide shafts allowing for a certain degree of
axial disc movement.
