yellow/green ground conductor.
5. The installation area must provide safe operating conditions for the operator, including sufficient room for
the operator and other personnel to stand clear of the load at all times.
RIGGING THE HOIST:
1.Before each use, visually inspect the hoist and all load bearing parts of the hoist, like hook and chain.
2.Make sure the intended structural support component is able to safely absorb the chain hoist lifting capacity.
3. Attach the chain bag to the chain bag ring.
4. Put the chain into the chain bag and make sure there are no twists or knots in the chain in the chain bag.
5. Attach the chain hook to the main structural support member, either direct to an existing eyebolt or lug-plate,
or using a bracket or beam clamp. It is also possible to use a sling or bridle. Avoid slinging on sharp edges.
6. Connect the power (and control) cable and make sure these will have proper stress relieves and sufficient
slack in every direction of planned tilting of the load. Use Velcro or cable-strings to tie the cable to the hoist
body or lifting hook.
7. Lower the chain hook by letting the chain run out to the required height.
8. Put the load under the chain hook.

6. Electric hoist can be mounted upright as “motor up” in the traditional industry situation or “motor down”,
which has become standard in the entertainment touring industry. Always ensure that it is clear whether
the load chain shall move or whether the hoist housing shall move. This does have effect on the way power
and control cables should be run.
7. When installing a three phase chain hoist, check and make sure the chain hoist travels in the direction
intended when operating the controls. To correct improper motor travel, reverse any two wires (except the
yellow/ green ground wire) at the power source. Do not change the connection in the chain hoist. Once the
direction of travel is verified to be correct, permanent connections can be made at the power source.
7. MAINTENANCE AND ADJUSTMENT
7.1 Inspections & Maintenance
To maintain continuous and satisfactory operation, a regular inspection procedure must be initiated to replace
worn or damaged parts before they become unsafe. Inspection intervals must be determined by the individual
application and are based on the type of service to which the hoist will be subjected to the degree of exposure
to wear, deterioration or malfunction of the critical components.
The type of service to which the hoist is subjected can be classified as Normal, Heavy, or Severe.
Normal Service: Involves operation with randomly distributed loads within the rated load limit, or uniform loads
less than 65% of rated load for not more than 25% of the time.
Heavy Service: Involves operating the hoist within the rated load limit which exceeds normal service.
Severe Service: Normal or heavy service with abnormal operating conditions.
Two classes of inspection- frequent and periodic –must be performed.
Frequent Inspections: These inspections are visual examinations by the operator or other designated
personnel. Records of such inspections are not required. The frequent inspections are to be performed monthly
for normal service, weekly to monthly for heavy service, and daily to weekly for severe service, and they should
include those items listed in below.
Periodic Inspections: These inspections are visual inspections of external conditions by an appointed person.
Records of periodic inspections are to be kept for continuing evaluation of the condition of the hoist. Periodic
inspections are to be performed yearly for normal service, semi-annually for heavy service and quarterly for
severe service, and they are to include those items listed in below.
CAUTIONS: Any deficiencies are to be corrected before the hoist is returned to service. Also, the external
conditions may show the need of disassembly to permit a more detailed inspection, which, in turn, may require
use of nondestructive type testing.

HOOK INSPECTION
Hooks damaged from chemicals, deformations or cracks, or that have more than a 10 degree twist from the
hook’s unbent plane, excessive opening or seat wear must be replaced. Also, hooks that are opened and allow
the latch to not engage the tip must be replaced. Any hook that is twisted or has excessive throat opening
indicates abuse or overloading of the unit. Inspect other load sustaining parts, hook block screws, load pins
and hook block bodies for damage.
Check to make sure that the latch is not damaged or bent and that is operates properly with sufficient spring
pressure to keep the latch tightly against the tip of the hook and allow the latch to spring back to the tip when
released. If the latch does not operate properly, it should be replaced.
To measure opening, depress latch against hook body as shown. Replace the hooks when opening is greater
than 38 mm.
e)
External evidence of excessive wear of brake parts.
f)
Checking the operation of the control station
making sure the buttons operate freely and do not
stick in either position.
g)
Inspect the electrical cords and cables and control
station enclosure for damaged insulation.
h)

CHAIN
1. Clean chain with a non-caustic/non-acid type solvent and make a link by link inspection for nicks, gouges,
twisted links, weld splatter, corrosion pits, striations, cracks in weld areas, wear and stretching. Chain with
any one of these defects must be replaced.
2. Slack the portion if the chain that normally passes over the liftwheel. Examine the interlink area for the point
of maximum wear. Measure and record the stock diameter at this point of the link. Then measure stock
diameter in the same area on a link that does not pass over the liftwheel and compare these two
measurements.
3. Also check chain for stretch using a larger caliper as show below to measure the outside length of a
convenient number of links about 11 (pitchs). Measure the same number of links in a used section of chain
and calculate the percentage increase in length of the worn chain.
4. Chain is to be kept clean and lubricated. Visually check chain every time chain hoist is used. As oil needs
to sit at the bearing surface of each chain link, it is advised to submerge the chain in oil for 30 min. Take it
out and let the chain hang dripping for 24 hours before putting in the hoist.

Note: In the entertainment industry chain wear in general is only very limited, and often even impossible to
measure after 10 years of normal use. On the other hand it is a well known fact that the load chains in the
entertainment do tend to be misused or even abused and sometimes badly neglected in corrosion prevention.
Severely damaged, deformed, dented, partly eaten or even broken chain links have been regularly reported
by users in the entertainment sector, and constant attention must be given that such chains are immediately
taken out of service. All this is typically the responsibility of the customer or user of the chain hoist.
CHAIN SPECIFICATION:
•diameter: 7.3 mm
•pitch: 20.2 mm
