G8703-G8708 Chain Hoists -5

OPERATION
1. Secure the hook which is directly
attached to the gear block body to
a structurally sound overhead
beam which is capable of handling
the weight to be lifted. The hoist
can be mounted to a beam trolley
if the capacity of the trolley system
is equal to or greater than the
anticipated load.
2. Position the load directly under the
chain hoist. Connect the load hook
to the item. Positioning the hook
on the load may require lifting
straps or chains if a suitable lifting
device is not incorporated on the
load (e.g. an eye bolt). Never wrap
the hoist’s lifting chain around the
load. Always use a separate set of
straps or chains which should then
be connected to the load hook. Be
sure the load chain is not twisted
or entangled in the lifting chain.
3.
Pull on the lifting chain with even
pulls until the chain between the
load and the gear block is taught.
Inspect the load chain and hook
position to make sure it will stay
properly positioned as the lifting
continues.
4. Continue pulling the lifting chain
evenly and steadily until the load is
raised.
5. Move the truck or pallet you are
placing the item on under the
raised load. If the Hoist is attached
to a travelling trolley system, move
the load slowly and carefully, mak-
ing sure that no one passes
beneath the load as it traverses.
6. When the load is positioned as
desired, pull in the opposite direc-
tion on the lifting chain until the
tension on the load chain has been
released.
7. Release the load chain.
1. Clean any dirt off of the hand and
load chains and gear block to
avoid having any foreign material
potentially interfere with the brake
and ratchet system.
2. Periodic lubrication with a light
grease on the gears inside the
chain gear block will ensure free
and smooth operation. Grease can
be applied with a scrap piece of
wood through the opening in the
bottom of the gear block.
3.
Generally disassembly of the gear
block mechanism should never be
required. If it should become nec-
essary, this maintenance should
be performed by a skilled service
technician who is familiar with
these types of lifting devices.
4. If the device is disassembled for
servicing, be sure to check the
hoist with a light load to be sure
the brake mechanism is proper-
ly holding the lifted load. If it
appears okay with a light load,
move to a load at its maximum
capacity and perform the same
check
MAINTENANCE
Disassembly and improper
reassembly of this device can result
in the braking or locking mecha-
nisms not working properly. Loads
may not stay suspended and might
cause a crushing injury. Always
have this device serviced by an
qualified repair technician. Serious
injury will result.
