Checking the limit switch
If the load hook is moved against the hoist, the limit switch must stop the lifting operation immediately and shut down the motor. The
load hook can only be lowered then.
The lowering movement must also be automatically stopped exactly the same way as soon as the load hook reaches the lowest
possible position allowed by the load hook length. The load hook can then be raised.
Inspect the traverse (for trolleys)
Inspect the traverse for correct assembly and visually check for external defects, deformations, superficial cracks, wear or signs of
corrosion.
Especially make sure that the roll pins are properly fitted to the centre traverse.
Check adjustment of trolley width
On hoists with trolley check that the clearance between the trolley wheel flange and the beam outer edge is equal on both sides and
within the tolerances given (see page XX, Fig. XX).
Enlarging the clearances, e. g. to enable the trolley to negotiate tighter curves, is forbidden.
Traversing the hoist
Plain trolley:
Push the hoist or attached load.
Reel trolley:
Geared trolley:
By operating the trolley hand chain.
Electric trolley:
By operating the ► resp. ◄ button.
For trolleys with two speeds: The first stage of button depression activates the slow speed., further depression activates the fast speed.
Use the slow speed for short periods only.
Attention: Never pull on the pendant control cable. Suspended loads may only be pushed.
Operation of the locking device (optional for models with an integrated manual trolley)
The locking device is used for easily locking the unloaded trolley (parking position in the shipping sector, for example). The brake shoe
is pressed against the beam flange by pulling on the appropriate hand chain fall so that the chain wheel turns clockwise. Only tighten
the chain by hand for this process. The locking device is released again by pulling on the other chain fall.
Attaching the load
Attach the load to the hoist using only approved and certified slings or lashing devices. Never use the load chain as sling chain. The
load must always be seated in the saddle of the hook. Never attach the load to the tip of the hook. Do not remove the safety latch from
the load hook.
Lifting/lowering the load
The load is lifted by depressing the ▲-button, it is lowered by depressing the ▼-button. For hoists with two speeds: The first stage of
button depression activates the slow speed, further depression activates the faster speed. The slow speed may only be used for short
distances.
In order to raise the load, always use the lowest available lifting speed. The chain must be loaded at this speed and may not lie slack on
the floor.
The chain end stop may not be used as operational limit switch.
Limit Switches
The unit has two limit switches for the lowest and highest load hook positions. The limit switches provide safety and should not be
reached operationally.
Emergency stop
All movement can be immediately halted by depressing the red, mushroom shaped button on the pendant control.
ATTENTION: The device is not free of tension!
To release the unit, turn the buttons in the clockwise direction.
