Users are to be specifically nominated by the company and
must be familiar with all relevant safety regulations.
Traversing the trolley
Plain trolleys: Pull on the load chain of the hoist.
Attention: Never pull on the pendant control cable.
Geared trolleys: By operating the trolley hand chain.
Electric trolleys: By operating the
4
- resp.
3
-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.
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 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.
Never remove the safety latch from suspension or load
hooks.
Lifting / lowering the load
The load is lifted by depressing the 5 -button, it is lowered
by depressing the 6 -button. For hoists with two speeds:
The first stage of button depression activates the slow
speed, further depression activates the faster speed. Use
the slow speed for short periods only. Do not use the chain
end stop as operational limit device.
Emergency stop
All movement can be immediately halted by depressing
the red, mushroom shaped button on the pendant control.
Attention:
Operating the red emergency button does NOT
automatically disconnect the mains supply to hoist or trolley .
To release the emergency stop, rotate the button in an anti-
clockwise direction.
4. FUNCTIONAL CHECK AFTER ASSEMBLY
Prior to operating the hoist, grease the trolley pinions (manual
geared and electric trolleys) and lubricate the load chain when
it is not under load (see page 8).
Before the hoist is put into regular service, following
additional inspections must be made:
• Are all screwed connections on 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 chain drive correctly reeved?
• Is the chain end stop correctly fitted to the loose end of
the load chain?
• All units equipped with two or more chain strands
should be inspected before initial operation for twisted or
kinked chains. The chains of 2-strand hoists may be twisted
if the bottom block is rolled over .
• Perform an operation cycle without load. The chain
should move in a steady , smooth way. Check the function
of the overload device by raising the bottom block against
the hoist body (max. 5 sec.).
• Check the brake function when lifting and lowering. The
braking distance must not be more than 50 mm.
• Traverse the trolley (if available) the complete length of
the trolley runway ensuring that the 2 - 4 mm lateral
clearance between the trolley wheel flange and the beam
outer edge is maintained at all times. Check that beam
end stops are positioned correctly and secure.
5. OPERATION
In addition to the recommendation in section 1, following
rules must be strictly maintained to ensure the safe
operation of the hoist:
Installation, service, operation
Users delegated to install, service or independently
operate the hoist must have had suitable training and be
competent.
