For installations where the trolley can not be slid onto the
end of a beam, leave the load pin nuts loose enough to get
the wheels around the beam flange. Check the flange width
setting before tightening the nuts to 125 ft-lbs. Be sure to
have end stops on your beam.
3. Before operating the hoist, be sure to observe the following:
a. ALWAYS DISCONNECT HOIST FROM POWER SUPPLY
before removing electrical cover or when making any
electrical connection in the hoist or pushbutton station.
b. The ground wire (green colored) of the power cable
should always be connected to a suitable ground by
means of a screw or clamp. An alligator clip does not
make a safe ground connection.
c. When installing a three-phase hoist, make only temporary
connections at the power source. Push the “UP” button
and observe the direction of the load block. If it raises, the
phasing is correct and permanent connections may be
made at the power source. If the load block lowers when
the “UP” button is pushed, release the button immediately
since the limit switches will not operate to protect the hoist
from over-travel. Reverse any two wires (except the green
ground wire) at the power source to correct the load hook
direction (phasing). Do not change connections in the
hoist or pushbutton assembly.
d. Make sure load chain is not twisted as it travels into the
hoist.
e. Operate hoist in a hanging position only. Hoist should be
permitted to align itself for a straight line pull. Do not
attempt to pull around corners.
f. Read ASME-B30.16 Safety Code for Hoists.
4. Lubricate the chain if necessary, see LUBRICATION,
page 9.
5. Check the function of the limit switches. Before placing hoist
in operation, check limit switch settings. Operate pushbutton
until near stop point and inch into stop limit, both top and
bottom. If either switch is not correct, adjust according to
LIMIT SWITCH ADJUSTMENT, page 8.
CHAIN CONTAINER
(Optional Accessary)
Refer to Table 4.
For installations where the slack chain hanging from the hoist
may be objectionable or hazardous, the use of a chain
container is recommended.
Available chain containers include the standard containers
designed for lifts of up to 50 ft on single-chained hoists and 25
ft on double-chained hoists. For longer lifts, the JLC927-5
container is available. For applications where a fabric bag is
preferred, the JLC927-20F, JLC927-40F and the JLC927-70F
are all options.
Instructions are provided with each of these chain containers
and must be adhered to closely to ensure a proper installation.
To install the long lift chain container or a fabric chain
container, you must follow instruction sheets provided with the
chain container. The following instructions are for the standard
metal chain containers only.
Installation of Standard Chain
Containers
(JLC927-1)
Refer to Figure 1.
1. Remove retaining clip and attachment pin and let the slack
chain hang free.
Do not attempt to store more chain in chain
container than that specified in the table below or
serious damage to hoist may result and hazardous
conditions may be created.
