(a) Automatic Safety Brake
Some Bloom Speed Reducers are equipped with an automatic hydraulic brakes to hold suspended loads. If your
Speed Reducer is not equipped with one, it is intended for pulling loads only. If you wish to lift and suspend loads with
your Speed Reducer, it can be retrofitted with a brake. Please consult the factory for details. The safety brake is an
important feature of your Speed Reducer and must be maintained properly There are two types of brakes used on
important feature of your Speed Reducer and must be maintained properly. There are two types of brakes used on
Bloom Speed Reducers:
Adjustable Automatic Safety Brake (Drag)
An oil cooled automatic safety brake disengages when a load is lifted or moved forward and automatically engages
when power is removed or the load is lowered or if the load tries to roll backward. IT IS EFFECTIVE IN ONLY ONE
DIRECTION. Make sure the braking action is taking place in the correct rotation. See instruction for; “Assembly
Instructions Oil Cooled Adjustable Automatic Safety Brake”
Instructions, Oil Cooled Adjustable Automatic Safety Brake .
Automatic Hydraulic Fail-Safe Brake (Spring applied hydraulic release)
Spring applied hydraulic release brake automatically holds load when hydraulic pressure is released. Double counter
balance valve adds additional load holding capability by locking hydraulic oil in motor.
