Description and functions
The EBRA20 guide rail brake is used as an ascend-
ing car over speed protection safety device.
EBRA20 is used when the motor-brake effects not
direct to the traction sheave or to the axle of the
traction sheave quite near of this. It acts onto the
car guide rail an reduces the car speed according
to the regulations (EN81-1:1998 9.10.4). The brake
operates with two spring loaded brake shoes an is
opened by an electro magnetic coil. The max.
retardation is 1.0 g.
The brake is installed above the overhead beams of
the sling and it replaces the sliding guide shoe of
the car (the guide shoe of the car is integrated to
the brake body - to be used with sliding guide
shoes only).
EBRA20 is a stand alone braking system which only
needs the tripping information (over speed gover-
nor switch) from the elevator.
The EBRA20 may be used for electrical operated
passenger an goods lifts according EN81-1. The
system does not substitute the safety gear for
down direction.
The settings are carried out in the factory (accord-
ing to the elevator data) an sealed.
