4.5 Testing
After any installation or repair, testing should be
performed to ensure smooth operation and
proper brake function. To test the hoist, first lift
a light load and then carefully lift 125% of the
rated load a few inches from the floor. Be sure
the brake holds the loads in both tests securely
before further lifting. No movement of the hook
should occur for any load within the rated hoist
capacity. Any testing should be performed by
qualified persons and documented in writing.
Refer to ASME B30.16 and HST-2M as well as
other pertinent federal, state, and local
regulations.
5) MAINTENANCE
5.1 Removing the Handwheel Cover
a) If a load is attached to the hoist, it shall
be removed.
b) Signs and barriers shall be used on the
floor beneath the hoist where overhead
maintenance work creates a hazard.
Remove the handwheel cover by removing the
following items from the three bolts on the
cover:
>> 3 12mm nuts
>> 3 Locking washers (see Figure 9)
>> 3 Flat washers
5.2 Installing the New Hand Chain
1) Remove the old hand chain, if necessary,
by cutting or bending the "C-link" (see
Figure 10).
2) Cut a new hand chain to the correct length.
The length of chain needed is equal to
double the height of lift required. If desired,
subtract approximately 4 feet to keep the
hand chain from touching the floor during
operation.
3) Remove the handwheel cover as described
above.
4) Insert the first few links of the new chain into
the handwheel, being sure to direct the
welds away from the handwheel
5) Turn the handwheel until the chain begins to
emerge.
6) Check to be sure the links on the hand
wheel are correctly placed (welds directed
away from the handwheel).
7) Reinstall the handwheel cover.
8) Pull on the chain until a few feet are avail
able.
9) Connect both ends of the new hand chain
using a "C-link".
10) Close the "C-link" properly using a vise and
pliers.
