electric control box, and inspect if handle switch, universal switch and motor is
normal.

Checking electromagnetic brake:
a. The spacing between the armature
and the electromagnetic disk should
be within 0.8-1.0 mm (see figure 10).
First, loose inner hexagon screw (1),
then adjust
the spacing by turning
hollow screw (4).
Finally, tighten
inner hexagon screw (1).
b. Power on to check the operation
of electromagnetic armature, the
armature must separate
with
friction
disc
completely
after
being
absorbed,
and no clog after power is off. The
armature
should press the
spring
disc completely under the
force of
spring.

Checking
safety lock: move the suspended platform upward about 1-2 m and
make its one end inclined about 3
°～

, the safety lock should be actuated to lock
the safety steel rope.
5.1.5
Make the suspended platform upward and downward 3-5 times for about 3-5 m
travel and check:
a.
The noise of the hoist should be normal and the electromagnetic brake will be
actuated reliably.
b.
Press emergency stop button or pull the limit switch, the suspended platform will
stop moving immediately.
c.
Make the suspended platform horizontal, if necessary.
5.1.6
Checking manually descending: move the suspended platform upward for about
3-5 m and stop it. Pull the manual descending device, the suspended platform can
move downward smoothly.
5.1.7
Adjustment of the upper limit stopper: move the suspended platform upward to
the highest position. Fix the limit stopper and adjust the location of the limit switch
and make sure that the limit switch will be actuated normally.
5.1.8
Rated load testing: The rated load should be evenly distributed on the working
platform. In the operating process no abnormal sound, and when stopping no sliding
movement. The safety lock should lock the safety steel rope flexibly and reliably
when the platform is in tilting.
