2. Before operating the hoist, be sure to observe the following:
a. ALWAYS DISCONNECT HOIST FROM POWER SUPPLY
before removing the 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.
3. If necessary, lubricate the chain, see LUBRICATION,
page 9.
4. Check the function of the limit switches. Before placing hoist
in operation, check limit switch adjustment. 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.
Installation of Standard Chain
Containers
Refer to Figure 1.
1. Remove retaining clip and attachment pin and let the slack
chain hang free.
2. Run load hook down to its lowest position. Place the slack end
of chain in chain container. Do not remove the chain stop.
3. Place chain container flush against housing with chain
stripper between top lugs. Insert long attachment pin and
replace retaining clip.
4. Feed the remainder of chain into container by operating
hoist in the “UP” direction to the top limit. This will permit the
chain to pile freely and prevent the chain from kinking, which
may occur if the chain is placed in the container by hand.
OPERATION
This hoist is designed for safe operation within the limits of its
rated capacity. It is controlled with the “UP” and “DOWN”
buttons of the pushbutton station. There are many safety
features to protect the operator from injury due to failure of the
hoist. Here are some points which should be observed to
maintain safe operation.
1. Do not overload the hoist.
2. Do not make extreme side pulls with the hoist.
3. Operate the hoist only in a hanging position with
adequate support.
4. Do not “sling” the load hook and chain around the load.
Use an approved sling.
5. Be sure there are no twists in the load chain as it travels into
the hoist housing. This condition should be constantly
checked on double chain hoists because it is possible for the
load block to be “capsized” or turned over one or more times.
6. Before raising a load, always check to see that it is held
securely in the hook or sling chains, etc. Raise the load
only until the load chain is taut and then double check the
rigging before continuing to raise the load.
7. Do not stand beneath a load! Do not move a load in such a
manner as to endanger personnel.
8. Do not lower into areas where visibility is obscured unless
someone else is guiding the operation.
9. Use common sense at all times when operating a hoist.
10. Do not operate if direction of hook travel is not the same as
indicated on button being pushed.
11. Do not operate unless hook travel limit devices function.
Test without load each shift.
5
Do not allow load to come in contact with the chain
container. If this situation exists reset the “UP” limit
switch so that the hook block stops below the chain
container (See LIMIT SWITCH ADJUSTMENT, page 8).
