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.

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

LUBRICATION
To make sure continued satisfactory operation of the hoist, all points requiring lubrication must
be serviced with the correct lubricant at the proper time interval as indicated for each assembly.
Correct lubrication is one of the most important factors in maintaining ecient operation.
The lubrication intervals recommended in this manual are based on intermittent operation of
the hoist eight hours each day, ve days per week. If the hoist is operated almost continuously
or more than the eight hours each day, more frequent lubrication will be required. The lubricant
types are based on operation in an environment relatively free of dust, moisture, and corrosive
fumes. Use only those lubricants recommended. Other lubricants may aect the performance of
the hoist. Approval for the use of other lubricants must be obtained from your Ingersoll Rand
Technical Support Department or distributor. Failure to provide proper lubrication may result in
damage to the hoist and/or its associated components.

AVISO
Consulte el manual de información sobre las piezas del producto para obtener detalles
sobre los componentes y las piezas que se indican a continuación.
Carcasa
La carcasa y la cubierta están hechas de aluminio fundido de gran resistencia, y las aletas disipadoras
en la zona del motor permiten un enfriamiento eciente. El contenedor de la cadena se puede unir a
la carcasa compacta. Se proporcionan oricios para la conexión del cable de alimentación y el cable
de control. El sistema de suspensión con argolla o gancho se conecta a la brida superior.
Motor y freno
Los polipastos eléctricos de cadena ELK son impulsados por motores asíncronos. Se dispone
de modelos de una y dos velocidades. Los motores están especícamente diseñados para las
exigencias de los polipastos y son aptos para izar equipos. Los arrollamientos del motor tienen
aislamiento clase F. El sistema de frenado consiste en un freno de discos múltiples alimentado
por CC. En el estado desenergizado, un tornillo de compresión provee el torque de frenado.
Embrague deslizante
El embrague deslizante está instalado en una ubicación funcional aguas abajo del sistema de
frenado. Este embrague protege al polipasto contra sobrecargas y, adicionalmente, funciona
como tope de emergencia en las posiciones mínima y máxima del gancho. El embrague deslizante
cumple con las exigencias de los estándares industriales y no requiere mantenimiento.
Fin de carrera
El sistema cuenta con un n de carrera mecánico para controlar las alturas máxima y mínima de
la cadena. Como complemento adicional, se pueden instalar posteriormente contactos de n de
carrera intermedios con desconexión automática.
