D4065/D4057 Ratchet Hoist Manual
-5-
OPERATION
To operate the ratchet hoist, do these
steps:
1. Read and follow the safety
precautions included in the front of
the manual, wear protective head
gear, and clear the area around the
lifting operation.
2. Secure the safety hook on top of the
hoist housing to a structurally sound
overhead beam that is capable of
supporting the load weight.
Make sure that the overhead
connection point conforms to the
required local and state safety and
building codes for the hoist and load
used.
Note: The hoist can be mounted a
beam trolley if the capacity of the
trolley system is at least twice the
maximum load capacity of the hoist.
3. Position the load directly under the
ratchet hoist.
Always connect the ratchet hoist
lifting hook to a separate lifting
device attached to the load, such as
straps, chains, or eye bolt. DO NOT
wrap the hoist lifting chain and hook
around the load in any way. If you
do, the dynamic loads could exceed
the capacity of the hoist, causing it
to fail and drop the load. A falling
load could cause death or serious
crushing injuries.
4. Flip the lever on the ratchet handle
to the neutral ("N") position. This
allows the lifting chain to freely move
through the gear block housing by
either pulling on the lifting chain or
rotating the handwheel.
5. Make sure the chains are not tangled,
then attach the lifting hook to the
load.
6. Eliminate the slack in the lifting chain
between the gear block housing and
the load by pulling on the chain.
7. Flip the ratchet lever to the "UP"
position, then pull on the ratchet
handle until there is slight tension on
the lifting chain.
8. Inspect the hoist and load to make
sure that the lifting chain will stay
vertical and will not twist during
the lifting operation, that there
is not a possibility of any type of
entanglement, and that there are no
obstacles in the path of the lift.
9. While keeping to the side of the
lifting path, continue to pull on the
ratchet handle with a slow and steady
pace.
Note: The ratchet mechanism will
suspend the load at the current
position when you release the
ratchet handle.
10. To lower the load, flip the ratchet
lever to the "DOWN" position, then
pull on the ratchet handle with a
slow and steady pace.
11. When the tension between the hoist
and the load is completely released,
detach the hoist hook.
