All control elements of the controls must always be
free-moving.
왘
Unload the JDN Air Hoist.
왘
Briefly actuate and release all control elements of the
controls one after another. The control elements must
return to their initial positions immediately. The
switching on and off function must operate correctly.
왘
PRESS the EMERGENCY STOP button. Each movement
of the hoist must stop. Actuation of the control
elements must not cause a lifting or lowering
movement.
왘
RELEASE the EMERGENCY STOP button by turning.
DA N G E R !
If a control element is stiff or remains in the
actuated position, do not use the hoist. The
controls must be repaired.
The main air emergency-stop valve is opened with each
actuation of the controls. It closes when the controls
are released.
With each check, the working order of the valve must
be examined as follows:
왘
Shut off the compressed air supply and unload
the line.
왘
Remove retaining ring 1 .
왘
Pull out cover 2 .
왘
Press plunger 3 inwards against the force of spring 4 .
It must return again due to the spring force.
왘
If the plunger does not move, the valve must be
repaired.
왘
Check that the direction of movement of the load
hook corresponds to the direction indicated by the
arrows on the control elements.
Independent of the stipulated inspection intervals,
the silencer must be checked for permeability if the
hoist does not achieve the specified lifting speed
(see
Technical data section, page 64 and 66).
The test is performed by comparing the lifting speeds
under nominal load, with and without the silencer.
The speed with standard silencer or filter silencer must
be at least 80 % of the lifting speed without a silencer
element. In the event of lower values, the silencer
elements must be cleaned or replaced.
