4.2

Dynamic functions test

Nobody should be in the lift car, on the car
roof or in the lift shaft when carrying out
test runs or functions tests!

General notes:

Each  gripping  test  has  to  be  documented  and  a
copy of the test report should remain in the eleva-
tor book.

After each test or activation of the safety
gear check that there are no defects that
can impair the normal run of the elevator.

Change the safety gear if there is a damage
on it. A visual check is sufficient.

It  is  recommended  to  do  the  test  near  a
door,  to  unload  the  weights  and  make  it
easier to lift up the elevator after testing
the safety gears.

4.2.1

Gripping test for car safety gear

Method A - Gripping test with overload

-

125% of the rated load in the car

-

gripping speed = nominal speed or lower

•

Secure the counterweight safety gear (if any)
by tying the safety gear lever up. This prevents
unintended  gripping  of  the  counterweight
safety  gear  due  to  jumping  of  the    counter-
weight.

•

Place test weights (equal to 125% of the
rated load) inside the car. Distribute the
weights evenly.

•

Drive the car down with nominal or lower
speed, keep the machine brake manually
open. After reaching the test speed activate
the tripping function of the overspeed gover-
nor at the door zone.

•

If the car does not stop after 1-2 seconds close
the brake immediately.

•

Try  to  drive  the  car  down  to  check  that  the
safety  gear  has  engaged  (suspension  ropes
should slide on the traction sheave).

Method B - Gripping test with rated load

-

100% of the rated load in the car

-

gripping speed = tripping speed of the over-
speed governor

Always ensure that the travelling height is
high enough to keep the car from running
onto the buffer.

Three persons are required for the test. The first-
person keeps the machine brake open. The second
person monitors the speed of the elevator with a
manual tachometer. The third person observes the
distance to the pit. His task is to notify when the
machine brake must be closed if the safety gear-
does not grip within safe distance to the pit. After
switching the power OFF, if the safety gear does-
not grip within the value of nominal speed +2 sec-
onds close the machine brake. For example, if the
nominal  speed  is  3m/s  the  safety  gear  must  grip
within 5 seconds.

•

Secure the counterweight safety gear (if any)
by tying the safety gear lever up. This prevents
unintended  gripping  of  the  counterweight
safety  gear  due  to  jumping  of  the  counter-
weight.

•

Place test weights (equal to 100% of the rated
load)  inside  the  car.  Distribute  the  weights
evenly.
