CAUTION

The trolley must have at least the same lifting capacity as the electric chain hoist.

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.

EN

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

● Excessive impact or lifting of guided loads.

Excessive inching operations, ground mooring and running against limit switches, should be avoided.

Operating temperature is -15° to 50° C ( 5° F to 122° F).

Hoists are rated at H4 Duty Class in accordance with ASME HST-1-2012.

The manufacturer accepts no responsibility for any damage to this equipment, resulting from

abnormal operating practices.

START-UP

DANGER

Mechanical adjustments should be performed by authorized designated personnel.

CAUTION

The operating sta must carefully read the operating instructions of the electric chain hoists

before its initial operation and carry out all checks. Only when a safe operation has been

established may the device be put into operation. Unauthorized persons may not operate the

device or perform any work with the help of the same.

Transport and Assembly

For the transport and assembly of the electric chain hoists, the safety direction for handling with

loads are to be followed. Refer to Product Safety Information Manual.

The electric chain hoists must be assembled by qualied sta, always bearing in mind the accident

prevention directions. Before assembly the electric chain hoist must be stored in an enclosed

room or covered area. Should the electric chain hoist be destined for operation outdoors, then it

is recommended that a protection roof is erected to shield it from the inuences of the weather.

Whenever possible, the electric chain hoist should be transported in its original packaging. It is

recommended that the assembly and connection of the electric chain hoist is conducted on-site

by qualied personnel.

EN

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.

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.
