Braking System EBRA20
Operating instruction
6.1.3
Returning tests
Periodical examinations and tests shall not be
more stringent than those required before the ele-
vator was first put to service. Thus if the tests are
made they shall be carried out using reduced
speed to avoid causing exessive wear or impose
stresses likely to to reduce the safety of the eleva-
tor.
The operation of the EBRA20 brake can be tested
following the instructions in chapter 5 Function
testing.
And the static force produced by the brake just by
opening the motor brake when EBRA20 is braking
and checking that the car does not move.
The reset of the braking system must be
done by an expert person.
Each test has to be documented and a copy of the
test report should remain in the elevator book.
6.2
Maintenance and inspection
check list
To indicate when wearing parts of EBRA20 should
be changed use following list:
•
Brake shoes
are nominally
12mm thick and can be used to
thickness of 11.8mm.
Thickness should be checked
after every five emergency
braking (refer to chapter 6.2.1).
•
Sliding elements
are nominally
8.5mm thick and can wear to
7.5mm. If the thicknes is less
then 7,5 mm brake shoe touches
the rail and makes noise (refer to
chapter 6.2.2).
The burrs coming from the rail in braking
may stuck to the sliding element thus they
have to be cleared after a braking if the
brake makes noise.
•
Car sliding shoes
should be
changed as normal guide shoes
after the clearance between the
rail and shoe is above 2mm (refer
to chapter 6.2.3).
•
Battery
(optional) is changed every 2.5 years
or if U < 10V (refer to chapter 6.2.4).
•
Check state of EBRA20 brake and neighboring
components for damage, deformation or
heavy oxidation (rust)
•
Check brake switch for function
•
Clean system if dirt has built
