Transport And Storage; Examination And Maintenance - Pfeifer Rhino 250 Original Instructions Manual

12. Transport and storage

After use, secure against unauthorized and impermis­
sible use.
After use and before storage, remove any foreign matter
or dirt from the chain and hoist. Check the chain, hooks
and safety latches to be sure the hoist can be reused.
Store the lever hoist in an unloaded condition in a dry
and clean room.
A pulley block that shows signs of wear and/or damage
(e. g. defective safety latch with impaired safety function)
must not be put into operation.

13. Examination and Maintenance

Lever hoists are exposed to conditions during use that
can influence their safety.
Examination before every use
The user should visually check the safe state of use of the
lever hoist prior to each use. Look for obvious damage or
signs of wear and tear. In cases of doubt or in the case
of one or more defects/cases of damage, the lever hoist
must be decommissioned and inspected by a qualified
person.
General examination
Check the brake both in the loaded and unloaded state.
Before each lifting operation, the proper function of the
load brake must be checked by lifting the load slightly
and then stopping to ensure that the brake can hold the
load before the load is lifted. Position the lever hoist
between the load to be lifted and the suspension point.
Make sure that the hook is hooked in correctly and that
the safety flaps are engaged.
The chain links of the load chain are to be checked for
bending, cracks in the welded area or in the shoulders,
transverse cracks and notches, corrosion pits, streaking
(tiny parallel lines) and chain wear. The support surfa­
ces between the chain links must also be inspected.
The chain must be replaced if it does not fulfil one of
the checkpoints. Pay attention to lubrication and lubricate
as needed. Chain failure may result if the load chain is
not always clean and lubricated.
Examinations after exceptional events
Unusual events – e. g. accidents, sudden loading,
overheating, overloading, collision, exposure to acids
and chemicals – impair the operational safety of the
lever hoist. After such cases, take the lever hoist out of
service immediately and have it checked by a qualified
person.
Examination by a qualified person
At regular intervals, a qualified person has to perform
an examination in compliance with national legal regula­
tions. Unless otherwise specified, examination must take
place at intervals no longer than 12 months. With fre­
quent use near the maximum working load limit, under
conditions with limits of use, with increased wear and
tear or corrosion, this period must be shortened so that
the suitability for operation is ensured. Examination
includes a visual inspection and functional check. Exa­
mination must be documented and stored by the opera­
ting company. After long storage, when the regular term
has been exceeded or when the chain was not properly
stored, the chain sling should be checked by a qualified
person before the first commissioning.
After a lengthy period of storage, the lever hoist should
also be checked by a qualified person prior to initial
commissioning if the regular date has been exceeded
or if the lever hoist was not stored properly.
Discarding criteria
In case of the following defects, the lever hoist must be
immediately decommissioned for repair:
• the type plate of the lever hoist is illegible or missing
• Deformations on suspension, chain or other
attachment elements
• Impermissible wear and tear or elongation on a chain
link e. g. when the rated dimension of the inner length
is exceeded by 5 %. This corresponds to an outer
elongation of 3 % (Fig. 10)
• Average thickness loss of the chain link anywhere
in the device by >10 % (Fig. 11)
