Harrington Hoists and Cranes (N)ERCC Hoist - ((N)ER2) - Manual (Page 7)

3.3 Mounting Location
3.3.1
WARNING
Prior to mounting the hoist ensure that the suspension and its supporting
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.
3.3.2
NOTICE
See Section 6.8 of the ER2OM for outdoor installation considerations.
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.
CAUTION
Mount the hoist at a height that will allow the operator to maintain a clearance of at
least 4 inches (101.6mm) between the Cushion Rubber and the hoist body during operation.
3.4.4
WARNING
Ensure that the fixed suspension point rests on the center of the hook’s saddle and
that the hook’s latch is engaged.
3.4.5
3.5 Electrical Connections
CAUTION
3.5.1 Ensure that the voltage of the electric power supply is proper for the hoist.
DANGER
Before proceeding, ensure that the electrical supply for the hoist has been de-
energized (disconnected). Lock out and tag out in accordance with ANSI Z244.1 “Personnel Protection
-Lockout/Tagout of Energy Sources”.
3.5.2
3.5.3 Coiled Control Cable - The Coiled Control Cable connects to the hoist via an 8-pin (8P) Plug and
Socket. Make this connection as follows:
ƒ Refer to Figure 3-3.
ƒ Insert the 8P Plug into the 8P Socket on the hoist and hand tighten the Screw Coupling.
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:
ƒ Refer to Figure 3-3 .
ƒ Insert the 4P plug of the Power Supply Cable into the 4P Socket on the hoist and hand tighten the
screw coupling.
ƒ 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:
ƒ Install a guide wire system parallel to the beam.
ƒ For a manual trolley the guide wire should be positioned slightly outside the hoist's Cable
Support as shown in Figure 3-3 .
ƒ 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 (1.5 meters).
