The overload control is set in the factory according to the regulations; it is possible to adjust it later from
outside (see repair and maintenance section).
The slipping clutch prevents the lifting of a load that is too heavy by slipping through. In the standard design
with direct control the slipping clutch also takes on the function of an emergency final limit when the load is at
the highest and lowest position.
As an option the device can be supplied with an electronic overload control combined with a low voltage
control.
WARNING!
Never exceed the nominal load!
It is prohibited to use the emergency stop as operational limit switch.
NOTICE!
If it is necessary to approach the end stops during operation operating limit switches can be supplied (as an
option). These can, however, only be used with low voltage control.
Load
chain
Special quality load chain. As the individual components of the chain drive are matched precisely to each
other, only original chains may be used.
Load
hook
The load hook, which is made of highly stable forged steel, has a ball bearing. This facilitates attaching the
load and avoids the chain turning. The safety catch on the hook prevents the load from slipping out of the
hook unintentionally. The safety catch of the load hook must be able to move freely and be self-closing.
Chain
container
The chain container is made of unbreakable plastic, plastic-coated fabric or sheet steel. It will supply different
sizes for different chain lengths.
Control
The electrical chain hoists are controlled as standard as follows:
By direct control
By low voltage control, optionally.
A remote control is available as an option.
Control
switch
▫
Control switch suitable for single hand use.
▫
The control switch housing is made of shock- and fracture-proof plastic.
▫
The control cable is fitted with a stress-relief rope (not applicable for radio control).
▫
Plug-in connection for the control switch
Phase sequence- phase failure monitoring relay
All devices with low voltage control are equipped with a phase sequence and phase failure monitoring relay
as a standard. This will prevent incorrect phase sequence when connecting to the mains supply and will
switch off the device if phase failure occurs. In addition, all devices with low voltage control are equipped
with thermal sensors to protect the lifting motor and end switches for lifting/lowering as a standard.
