PRODUCT DESCRIPTION
(Figure 1)
„ Housing (Item 1 in figure 1)
The housing and the 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 the
control cable. The eye or hook suspension system is
attached to the top flange.
„ Motor and Brake (Item 2 in figure 1)
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 the lifting equipment. The windings of the
motor correspond with insulation class F. The brake system
consists of an AC-powered multiple disk brake. In the de-
energized state the braking torque is provided by the
compression spring.
„ Rotor Shaft with Integrated Slip Clutch
(Item 3 in figure 1)
The slip clutch is installed in a functional location upstream
of the brake system and is integrated in the rotor shaft. It
protects the chain hoist from overloading and provides the
additional function of an emergency limit stop for the highest
and lowest hook positions. The slip clutch complies with the
requirements of industry standard and is maintenance free.
„ Limit Switch (Item 4 in figure 1)
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 (Item 5 in figure 1)
The electric chain hoists are equipped with a 42V contactor
controller as standard. The emergency stop contactor
disconnects all three main power phases from the mains
when the E-Stop button is pressed.
„ Chaindrive (Item 6 in figure 1)
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 (Item 7 in figure 1)
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.
