3.0 Preoperational Procedures

3.2 Chain

3.2.1 Chain Components – Refer Figure 3-1 and ensure that stoppers and cushion rubbers are in the
correct location and properly installed. Never operate the hoist with incorrect, missing or
damaged chain components.

Figure 3-1 Chain Component Location

3.2.2 Chain Container – Install the chain container on the hoist body as shown in Figure 3-2. To place the
chain into the chain container, feed the chain into the chain container beginning with the free end. Take
care to avoid twisting or tangling the chain. NEVER put all the chain into the container at once. Lumped
or twisted chain may jam against the hoist body activating the friction clutch and potentially damaging
the chain.

structure are adequate to support the hoist and its loads. If necessary consult a professional that
is qualified to evaluate the adequacy of the suspension location and its supporting structure.

NOTICE

3.4 Mounting the Hoist

3.4.1 Manual Trolley - Follow instructions in Owner’s Manual provided with the trolley.

3.4.2 Motorized Trolley – Cylinder control model hoists are NOT intented to be used with motorized trolleys.

3.4.3 Hook Mounted to a Fixed Location - Attach the hoist’s top hook to the fixed suspension point.

energized (disconnected). Lock out and tag out in accordance with ANSI Z244.1 “Personnel Protection

-Lockout/Tagout of Energy Sources”.

Prior to mounting the hoist ensure that the suspension and it supporting

See Section 6.7 of the EROM for outdoor installation considerations.

Ensure that the fixed suspension point rests on the center of the hook’s saddle and

Ensure that the voltage of the electric power supply is proper for the hoist.

Before proceeding, ensure that the electrical supply for the hoist has been de-

3.5.3 Coiled Control Cable - The Coiled Control Cable connects to the hoist via a 5-pin (5P) or 8-pin (8P)

Plug and Socket. Make this connection as follows:

§ Refer to Figure 3-3.

§ Insert the 5P/8P Plug into the 5P/8P Socket on the hoist and hand tighten the Screw Coupling.

7

3.5.4 Power Supply Cable Hoist Connection – The Power Supply Cable connects to the hoist via a 4-pin
(4P) plug and socket. Make this connection as follows:

§ Refer to Figure 3-3.

§ Insert the 4P plug of the Power Supply Cable into the 4P Socket on the hoist and hand tighten the

screw coupling.

§ Install the Cable Support Arm (pre-installed on the Power Supply Cable) on to the Socket Holder

using the pre-installed Machine Screws and Lock Washers.

Use care to avoid twisting or kinking the Power Supply Cable.

3.5.5 Power Supply Cable Installation – If the hoist is hook mounted to a fixed support ensure that the
Power Supply Cable is properly installed and supported between the hoist and the electrical
power supply.

If the host is installed on a manual trolley, then the Power Supply Cable must be installed along the
beam that the trolley runs on. For curved beams a special cable suspension system will be
needed, and this instruction does not apply. For straight beams install the Power Supply Cable as
follows:

§ Install a guide wire system parallel to the beam.

§ For a manual trolley the guide wire should be positioned slightly outside the hoist's Cable

Support as shown in Figure 3-3.

§ Use the Cable Trolleys supplied with the hoist to suspend the Power Supply Cable from the
guide wire. Space the Cable Trolleys every 5 feet.

Figure 3-3 Coiled Control Cable and Power Supply Cable Connections

3.5.6 Connection to Electrical Power Source - The red, white, and black wires of the Power Supply Cable
should be connected to an Electric Power Disconnect Switch or Circuit Breaker. This connection
should be made so that the hoist is phased properly. Refer to Section 3.6.11 of the EROM for
instructions on how to check for correct power supply phase connection.

3.5.7 Fuse/Breaker Capacity -The hoist's power supply should be equipped with overcurrent protection such
as fuses, which should be selected for 110% to 120% of total listed full load amperage, and should be
dual element time-delay fuses. Refer to the motor nameplate for the full load amperage draw.

DANGER

shock hazard when touching any part of the hoist or trolley. In the Power Supply Cable the ground wire
will be either Green with Yellow stripe or solid Green. It should always be connected to a suitable
ground connection. Do not paint the trolley wheel running surfaces of the beam as this can affect
grounding.

Grounding - An improper or insufficient ground connection creates an electrical

4.3 Hoist Controls

4.3.1 Single Speed Hoists – Firmly hold the black Grip on the cylinder control. Slide the Up/Down Switch

Operator up to raise the load or down to lower the load as shown in Figure 4-1. To stop the hoist slide
the Up/Down Switch Operator back to the middle position.

4.3.2 Dual Speed Hoists – Select high or low speed using the Speed Selector Switch. Lights ajacecnt to the

Speed Selector Switch indicate if low or high speed is selected. Slide the Up/Down Switch Operator up
to raise the load or down to lower the load Figure 4-1. To stop the hoist slide the Up/Down Switch
Operator back to the middle position.
