Regulations in certain countries require that the operating point of overload protection is checked
annually by conducting an overload test. If local requirements necessitate an overload test, conduct
the annual inspection as follows:
• Prepare a test load that is 10 % heavier than the operating point for overload protection stated in the
written records for the test drive of the hoist. Raise the test load a little and only once. If the overload
protection halts the hoisting of the test load, it is operating correctly. If the overload protection does
not prevent hoisting of the test load, the overload protection must be re-adjusted.
!
Only a service agent authorised by the manufacturer may adjust the overload protection.
!
Do not repeat the overload test unnecessarily. The overload test is an actual overload. The
test can only be conducted in carefully prepared and properly supervised conditions.
5.32 Condition monitoring unit
The electrical cubicle on the hoist contains the condition-monitoring unit that supervises the safe
operation of the hoist. The unit collects data on functions that affect safety and calculates the remaining
time in the Safe Working Period (SWP) during which the hoist can operate safely. Separate operating
and servicing instructions for the condition-monitoring unit are delivered with the hoist.
!
Only qualified personnel authorized by the manufacturer of the hoist may do the
programming of the condition-monitoring unit.
