Hoist brakes are an essential safety feature of overhead
cranes. Designed to hold a load when the hoist motor is not running, these
brakes reduce the risk of falling loads that could result in injury and
property damage.
This section specifies the performance requirements of
hoist, or holding, brakes. It also calls for an additional control braking
mechanism to prevent overspeeding – that is, to prevent hoists from exceeding a
predetermined operating speed.
The Excel Clutch technical team can help you in your efforts
to maintain a safe, productive operation by inspecting your equipment and
performing needed service.
Brakes for hoists.
Each independent hoisting unit of a crane shall be equipped
with at least one self-setting brake, hereafter referred to as a holding brake,
applied directly to the motor shaft or some part of the gear train.
Each independent hoisting unit of a crane, except
worm-geared hoists, the angle of whose worm is such as to prevent the load from
accelerating in the lowering direction shall, in addition to a holding brake,
be equipped with control braking means to prevent overspeeding.
Holding brakes.
1. Holding brakes for hoist motors shall have not less than
the following percentage of the full load hoisting torque at the point where
the brake is applied.
125 percent when used with a control braking means other
than mechanical.
100 percent when used in conjunction with a mechanical
control braking means.
100 percent each if two holding brakes are provided.
2. Holding brakes on hoists shall have ample thermal capacity
for the frequency of operation required by the service.
3. Holding brakes on hoists shall be applied automatically
when power is removed.
4. Where necessary holding brakes shall be provided with
adjustment means to compensate for wear.
5. The wearing surface of all holding-brake drums or discs
shall be smooth.
6. Each independent hoisting unit of a crane handling hot
metal and having power control braking means shall be equipped with at least
two holding brakes.

and productivity of your operation.
Excel clutch is provides many Product in India just like - DC brake motors , AC fail safe brakes , bearing
mounted clutch , Spring loaded fail
safe brake , Geared brake motors , brake motors , Brake Rectifiers ,
hoist
brake motors. Electromagnetic brake motors India and gear motors couple a
standard AC motor with a power-off activated electromagnetic brake to hold the
load in position when the power is cut off.
