Overview

Seawater-protected spring-operated brake IP67
The solenoid double-disk spring-operated brake of type 4BZFM
(Stromag) brakes the motor if the supply is disconnected or in
the event of power failure. Motors with built-on brakes are mainly
used in cranes to drive traversing, trolley and hoisting gear, but
also in marine winch drives. The size of the brake depends on
the external moment of inertia, brake speed and the required
braking time.
Further characteristics of the solenoid double-disk
spring-operated brake of type 4BZFM
•
Seawater-protected solenoid double-disk spring-operated
brake
•
Torque range: 100 to 1600 Nm (static torque)
•
For use in cranes and offshore
•
A cast-iron cover ensures IP67 degree of protection, so
it can be used under the most difficult climatic conditions
•
All surfaces finished
•
When the cover is removed, the braking function is maintained
•
Minimal wear, brake pads are easy to replace
•
Emergency release
•
IEC – mounting flange
•
As an option: switching status indication, terminal box,
anti-condensation heater, prepared for tachometer mounting
•
Type approval: Germanisch Lloyd, Lloyds Register of
Shipping, American Bureau of Shipping
