CAUTION
Safety limit switch (4) is designed for overload mechanism supervision, not for
overload protection. Safety limit switch (4) does not measure load and it is no
substitute for load sensor (3).
7.2.8.1 Maintenance of overload device
1
2
Check the condition of the overload protection mechanism
and the mechanical limit switch. Clean if needed. Test the
safety limit switch (4) operation by pressing the switch
manually.
Lubricate the pivot joint of the lever mechanism, the
suspension support of the rope anchorage and the rocker
bushings of the support beam with suitable thin oil.
CAUTION
Safety limit switch is not adjustable.
Note: 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:
7.2.8.2 Operation test of overload device
1
2
Prepare a test load that is 10 % heavier than the operating
point for overload protection that is stated in the written
records for the test drive of the hoist. Raise the test load a
little and only once.
W = 110 % of Operating point of overload protection.
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 readjusted.
CAUTION
Only a service agent that is authorized by the manufacturer may adjust the
overload protection.
CAUTION
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.
