Intended Use
Quantum Series Electric Chain Hoists are designed to efficiently raise and lower
loads. These hoists are designed for general industrial material handling operations,
with freely suspended loads.
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
QCH 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.
Rotor Shaft with Integrated Slip Clutch
The slip clutch is installed in a functional location downstream of the brake system
and is integrated in the rotor shaft. 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.
Chaindrive
The hoist is equipped with a 5 pocket liftwheel and uses case carborized highly heat
treated load chain for long life. Chain guides are easily removed for inspection. All
hooks are equipped with a safety latch.
Gearbox
The two-stage, closed spur gearing is designed for lifting gear requirements. The
gear wheels are mounted on ball bearings and have continuous lubrication. The
helical gearing reduces running noise to a minimum.
Control Switch
The standard equipment of the electric chain hoist includes a control switch (raise/
lower with emergency stop). The automatically disconnecting emergency stop
contact of the control switch directly opens the power circuit which powers the
contactors. A 4-button or 6-button control switch is attached to the motorized trolley
as required for additional movement directions.
