Humidity:
Protection Class:
Solenoid Compatibility:
The trolley must have at least the same lifting capacity as the electric chain hoist.
Refer to the Product Parts Information manual for components/parts listed below.
Housing
The housing and cover are made from robust cast aluminium, and cooling fins in the motor area
provide efficient cooling. The chain container can be attached to the compact housing. Holes
are provided for the chain screw connection of the power supply connecting cable and control
cable. The eye or hook suspension system is attached to the top flange.
Motor and Brake
ELK electric chain hoists are driven by asynchronous motors. Models are available in single and
dual speed. The motors are specifically designed for hoist duty requirements and are rated
for lifting equipment. The windings of the motor correspond with insulation class F. The brake
system consists of a DC-powered multiple disk brake. In the de-energized state the braking
torque is provided by the compression spring.
Slip Clutch
The slip clutch is installed in a functional location downstream of the brake system. It protects
the chain hoist from overloading and provides additional function of an emergency limit stop
for the highest and lowest hook positions. The slip clutch complies with requirements of industry
standard, and is maintenance free.
Limit Switch
A geared limit switch is installed to control the highest and lowest chain positions. Intermediate
limit switch contacts with automatic disconnection can be optionally retrofitted.
Electrical Controller
The electric chain hoists are equipped with a 42 V pendant controller as standard. The emergency
stop contactor disconnects all three main power legs from the power source when the
Emergency-Stop button is pressed.
