4. Installation instructions before connecting
A.
Before first use
– Chain hoists with travelling trolley underlie the accident prevention regulation (UVV)
(Federal cooperative society regulations of Germany - DGUV Regulation 52).
Before the first initiation a quality inspection by a technical expert for cranes has to
be carried out. Please contact PLANETA for it. We will kindly advise you!
– Never use the hoist below -20 degrees Celsius or above + 60 degrees Celsius.
B. Installation and testing prior to each use
– Hang hoist with the clamp into the load carrying system and turn once.
– Hand chain and load chain must hang free and be without breaks or twists.
– Chain block: Pull through hand chain one time completely without load.
– Inspection of load brake: Lift up lightly the load and hold it. If load is safe, go on lifting.
When lowering, the load shall not slide after hand chain shutdown or stop of the lever.
– If everything is performed properly, operation can be started.
– Important for devices of multiple lines: Lower block shall not be snapped through the
chain loop. This can be recognised by a twisted chain. Each second chain link is in
one row not steadily in alignment. If the welded seams of the chain links are not in
same direction the lower block must be struck back through the chain loop.
– The last chain link must be fastened on the hoist body.
5. Operation
– Brake closes independently when hanging on the minimal load
(appr. 10% of nominal load).
– Chain block is only suitable for vertical lifting and lowering.
– To move the load the hand chain is pulled up or down.
6. Maintenance and inspection
Chains and Hooks
– The chains and clamps have to be inspected continuously! Clean chain before
inspection. Lubricate load chain from time to time! Never lubricate or grease the
brake!
– Retracted chain shall not click under load.
– Check chain for tension! The internal length
(t)
of a worn chain link, smallest
diameter of wire
(D)
and length of 11 chain links
(a)
are measured by a slide gauge
where the chain must be tightened firmly.
– Dimensions: If the deviations of measurement exceed the values
(a)
in the
following table substitute chain immediately. Measure of diameter
(D)
shall not be
under-run and the pitch
(t)
of the single link not be exceeded.
