4. FUNCTIONAL CHECK AFTER ASSEMBLY

Prior to operating the hoist, grease the trolley pinions (manual
and motor trolleys) and lubricate the load chain when it is not
under load (see page 8).
Before the hoist is put into regular service, following inspec-
tions must be made:
• Are all screwed connections on the hoist and trolley tight and
are all locking devices in place and secure?
• Are the end stops on the trolley runway in place and secure?
• Is the hoist correctly reeved?
• Is the chain stop correctly fitted to the loose end of the load
chain (see fig. 1).
• All units equipped with two or more chain strands should be
inspected before initial operation for twisted or kinked chains.
The chains of two fall hoists may become twisted if the bottom
block is rolled over.
• Perform an operating cycle without load. The chain should
move in a steady, smooth way. Check the function of the over-
load device (max. 5 sec.) by raising the bottom block against
the hoist body.
• Check the brake function when lifting and lowering. The brak-
ing distance must not be more than 50 mm.
• Traverse the trolley the complete length of the trolley runway
ensuring that the 2 - 4 mm clearance between the trolley wheel
flange and the beam edge is maintained at all times. Check
that the beam end stops are positioned correctly and secure.

Traversing the trolley
Hand trolleys: Pull on the load chain.
Attention: never pull on the air hoses
Geared trolleys: By operating the hand chain
Motor trolleys: By operating the "left" button or "right" button
on the LH side of the pendant control.
Consider the braking distance of the trolley. Do not use the
beam end stops as operational limit devices.
Attaching the load
Attach the load to the hoist using only approved and certified
slings / lifting gear. The load must always be seated in the
saddle of the hook. Never attach the load to the tip of the
hook. Never remove the safety latch from suspension or load
hooks.
Lifting the load
The load is lifting by depressing the "up" button, it is lowered
by depressing the "down" button on the RH side of the pen-
dant control. Do not use the chain stop as an operational limit
device (see fig. 1).
Emergency stop
All movement can be immediately halted by depressing the
red, mushroom shaped button on the pendent control.
Attention: The hoist is still filled with air. To release the
emergency stop, pull the button out again.
