NOTICE
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 ns in the motor area
provide ecient 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 ange.
Motor and Brake
ELK electric chain hoists are driven by asynchronous motors. Models are available in single and
dual speed. The motors are specically 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 retrotted.
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 three stage, closed spur gearing is designed for lifting gear requirements. The gear wheels
are mounted on roller 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.

INSTALLATION
Prior to installing the hoist, carefully inspect components for possible shipping damage.
Hoists are supplied fully lubricated from the factory. Refer to“Lubrication,”section for
recommended oils and lubrication intervals. Lubrication of the load chain is recommended
before initial hoist operation.
WARNING
●A falling load can cause injury or death. Before installing, read Product Safety
Information Manual.
●Owners and users are advised to examine specic, local or other regulations, including
American National Standards Institute and/or OSHA Regulations which may apply to a
particular type of use of this product before installing or putting hoist to use.
●The strength of the hoist, chain and hooks can be aected by chemically active environments,
such as caustic or acid substance fumes. A qualied person should be consulted before
hoists are used in chemically active environments.
Mounting
Always make certain the supporting member from which the hoist is suspended is strong
enough to support the weight of the hoist plus the weight of the maximum rated load plus a
safety factor (consult a structural engineer).
If the hoist is suspended by a top hook, the supporting member should rest completely within
the saddle of the hook and be centered directly above the hook shank. Do not use a supporting
member that tilts the hoist.
Hook Mounted Hoist
Place hook over mounting structure. Make sure hook latch is engaged.
Trolley Mounted Hoist
When installing a trolley on a beam, measure beam ange and temporarily install trolley on
hoist to determine the exact distribution and arrangement of the spacers. Adjust spacers in
accordance with trolley manufacturer’s literature to provide the correct distance between the
wheel ange and the beam. The number of spacers between the trolley side plate and mounting
lug on hoist must be the same in all four locations in order to keep the hoist centered under the
I-beam. The remaining spacers must be equally distributed on the outside of the side plates.
WARNING
At least one mounting spacer must be used between the head of each trolley bracket bolt
and the trolley bracket and between each trolley bolt nut and the trolley bracket. Failure to
do this could cause the hoist to fall when used improperly.
Make sure trolley bolts or nuts are torqued in accordance with manufacturer’s specications.
For installation of hoist and trolley on beam, make certain the side plates are parallel and vertical.
After installation make sure beam stops are in place, operate trolley over entire length of beam
with a capacity load suspended 4 to 6 inches (10 to 15 cm) o the oor.

Form 47584686001 Edition 5 9
EN
CAUTION
To avoid an unbalanced load which may damage the trolley, the hoist must be centered
under the trolley.
NOTICE
Trolley wheels ride on the top of the lower ange of the beam.
Power Connection
DANGER
Electrical connection adjustments should only be performed by authorized specialists.
The main connection cable, fuse and the switch must be installed by the customer before connecting
the electric chain hoist to the mains power supply.
A 4-wire cable with a ground protective conductor is needed to provide the power supply for three-
phase models. A 3-wire cable with a protective conductor is adequate for single-phase models. The
length and the gage must be determined to support the power consumption of the electric chain hoist.
DANGER
The ground conductor must not carry any power. With motorized trolley operation, the
power supply is enclosed in a terminal box on the drive motor. With the installation of a
motor protector, the load plate voltage of the electric chain hoist must be noted.
CAUTION
Checking direction of rotation: If the direction of rotation does not correspond with the
button symbols on the control switch, power supply wires L1 and L2 must be swapped
around.
WARNING
Electrical Connections if not tight and secure, will cause a re. During installation the
electrician must make sure that all electrical connections including the ground connection
are secure. Make sure all junction boxes and switch enclosures are adequately sealed and
protected for the environmental conditions to be encountered.
NOTICE
