5.5 Inspection
In principle we recommend one inspection every year, and a minimum of one before usage is
resumed. All of the following checks must be performed and documented by authorized
persons:
• Check the cabling (in particular for crushing, wear, cuts, visible parts of the insulation of
the inner wires, visible metal wire cores, kinks, bulges, colour changes of the outer sleeve,
brittle spots, and safe positioning so that mechanical effects such as being cut or crushed
are not probable).
• Visual inspection of the frame parts to check for plastic deformation and/or wear and tear
(frame, motor suspension, cantilever arm, spreader bar).
• Visually check for damage to the paintwork (danger of corrosion).
• Visual inspection of all casings for damage; screws must be tight.
• Verify the amount of grease on the metal joints of movable parts
• Visually check all plastic parts for cracks and brittle spots
• Review the control box + included charger residual discharge current (A) based on
VDE 0702
• Review the control box + included charger insulation resistance (MO) based on VDE 0702
• Functional test of the cantilever arm (lubrication of the joint parts, range of adjustability,
deformation, wear and tear)
• Check the functioning of the hoist drives (during a test drive → noises, speed, free running,
etc.), if necessary: Measure the performance, first with no load and then with the nominal
load ("SWL"), to investigate the wear and tear of the motors by comparing the values for
the electric current against the values when it was delivered.
• Functional test of the emergency stop
• Functional test of the emergency lowering
• Completeness of the delivery condition, instruction manual available?
Checking measurements may only be carried out by skilled persons trained on the patient hoist
at least and at least under the supervision of an electrician who knows the checking instruments
and processes. Only an electrician can release the patient hoist for use after making the
measurements and carrying out the servicing.
The service must only be signed off in the maintenance plan if a minimum of all the above-
mentioned aspects have been checked.
5.6 Expected lifespan
The average lifespan of the patient hoist is 8 years. Depending on the frequency of use, storage,
maintenance, servicing and cleaning, the lifespan of the patient hoist will increase or decrease.
5.7 Reuse
Before each reuse, have the patient hoist disinfected, inspected and serviced according to the
instructions in this chapter.
5.8 End of use
At end of life, you need to dispose of the patient hoist according to the local environmental
legislation. The best way to do so, is to disassemble the patient hoist to facilitate the transport of
recyclable parts.
