

HAZARDOUS VOLTAGES ARE PRESENT IN THE HOIST CONTROL BOX, IN THE SUPPLY OF ELECTRICAL
POWER TO THE HOIST MOTOR.

Before performing ANY mechanical or electrical maintenance on the equipment, de-energize (disconnect) the main
switch supplying power to the equipment; and lock and tag the main switch in the de-energized position. Refer to ANSI
Z244.1, “Personnel Protection – Lockout/Tagout of Energy Sources”.



Never attempt to hook mount an Electric chain hoist directly to the Suspension Shaft on

trolleys up to and including 3 Ton. These trolleys are designed to be used with a suspender only and do not
have the vertical clearance required for a hook to fit between the Suspension Shaft and trolley beam.

3.2.2

When the TS2 trolley is combined with a hoist, follow and complete all pre-operational procedures provided with
the hoist. For Harrington SH, ES and NES model hoists, follow the pre-operational procedures in the SH,
ES/NES Owner's Manual in conjunction with all information provided in this section for mounting and electrical
connections.

3.2.3

In addition to the information and procedures provided in this section for the TS2 trolley, there are specific
details for using SH, ES and NES hoists with TS2 trolleys. Special mounting and wiring considerations must be
taken if the trolley is used with a hoist other than an SH, ES or NES model.

3.2.4

Preparing SH, ES and NER hoists for use with TS2 trolley.

1) These instructions pertain to the mechanical coupling of the hoist to the trolley. Refer to the hoists owner’s

manual for the Electrical connections.

2) SH & ES Series Hoists couple directly to the trolley with suspender “E”, as shown in Figure 3-9 and Figure
