6.9 Overload cut-off
6.9.1 Description of system
The SLE21 / Multicontroller SMC21 load monitor with its electronic sensor is set in
the factory. Corrections are only permitted in special cases, see page 57.
The factory settings are shown under the front cover of the SLE 21 load monitor
(sketch).
6.9.2 Testing overload cut-off
If an overload is detected, the wire rope hoist is switched off in the upwards
direction. Only lowering is then possible. Lifting is not possible until the wire rope
hoist has been unloaded.
• Attach rated load +10% overload and take load up slowly. After the rope has been
tautened the overload cut-off must disconnect the hoist.
6.9.3 Maintenance of LET overload cut-off
After off-loading hoist, check all moving parts for ease of movement. Clean without
dismantling and grease from the outside with a thin-bodied lubricant.
See page 22 for a description of the system.
6.9.4 Maintenance of LEI overload cut-off
• Check thickness of plate (min. 1.5 mm). If necessary, replace plate after removing
screw (D).
