Connection to the electrical supply
An adequate supply system is required along the total length of travel (where appropriate). The supply
voltage and frequency, at which the hoist operates, is marked on the motor rating plate. It is imperative to
check before connecting the unit that these figures correspond with those of the supply voltage.
Mounting the hoist
Hang the hoist from its intended support. The structure used to support the hoist must have sufficient
strength to withstand several times the load amount. If you are not sure of the weight the structure can
hold, consult a registered engineer and the local building codes.
Suspending the hoist from an inadequate support could allow the hoist and load to fall
and cause personal injury and/or property damage.
To avoid injury: Make sure that the structure has sufficient strength to withstand several
times the hoist and its rated load amount. Using the upper hook, hang the hoist from the
support. Make sure the hoist is solidly held in the uppermost part of the hook arc and the
latch is tightly against the hook tip.
Load chain
The chain should feed smoothly into and away from the hoist and hook block (½ ton and 1 ton). If the chain
binds, jumps or is noisy, First clean and lubricate the chain, if trouble persists inspect chain and mating
parts for wear, distortion and other damages.
Load chain lubrication
Always lubricate load chain weekly or more frequently depending on the severity of service. Lubricate load
chain with a light coat of Lubriplate Bar and Chain Oil 10-R (Fiske Bros. Refining Co.) or equal lubricant.
Be sure the lubricant reaches the bearing surfaces between the links. Remove the excess oil from the
chain.
Used motor oils contain unknown carcinogenic materials.
To avoid health problems: Never use used motor oils as a chain lubricant. Only use
Lubriplate Bar and Chain Oil 10-R as a lubricant for the load chain.
Hook and eye suspension hoists
The suspension point should be of a correct size to admit the top hook or eye of the hoist and allow it
to rest properly on the saddle. It must be adequate to support the hoist while it is being operated at its
maximum capacity (safe working load).
Chain container
For installations where the slack chain hanging from the hoist may be objectionable or hazardous, the use
of a chain container is recommended.
Do not attempt to store more chain in the chain container than what is specified for the
hoist or serious damage to hoist may result and hazardous conditions may be created.
1.
Remove both bolts from the chain container mounting
bracket.
2.
Attach the chain container to the bracket.
3.
Reinsert the bolts.

Test and operational checks
On completion of installation, but before the hoist is put into regular service, the following procedure
should be carried out:
1.
Record the hoist's Code, Lot and Serial Number from the nameplate on the hoist.
2.
Check that the hoist is properly installed to either a fixed point or trolley, whichever applies.
3.
If the hoist is installed on a trolley, ensure that:
-
The trolley is properly installed on the beam.
-
The stops for the trolley are correctly positioned and securely installed on the beam.
4.
Isolate the power supply.
5.
Check that all mechanical and electrical joints and connections are tight and secure.
6.
Check that all nuts, bolts and split pins (cotter pins) are securely fastened.
7.
Confirm proper operation:
-
Before operating read and become familiar with this manual.
-
Before operating check to ensure that the hoist (and trolley) meet the Inspection, Testing and
Maintenance requirements of ANSI/ASME B30.16.
-
Before operating check that nothing will interfere with the full range of the hoist's (and trolley's)
operation.
8.
Switch on the power supply.
9.
Run lightly with no load, throughout the full extent of the hoist and check that the operation is smooth
at all times.
10.
Check the operation of the hoist brake, run under light load and full load conditions.
Check supply voltage before everyday use. If the voltage varies more than 10% of the
rated value, electrical devices may not function normally.
Confirm the adequacy of the rated capacity for all slings, chains, wire ropes, and all other
lifting attachments before use. Inspect all load suspension members for damage prior to
use and replace or repair all damaged parts.
Verify and correct all chain irregularities prior to operating the hoist.
Unpacking
Once the package has been opened, carefully inspect the hoist frame, hooks, chain and control station for
damage that may have occurred during shipment.
Operating a unit with obvious external damage may cause a load to drop and could result
in personal injury and/or property damage.
To avoid injury: Carefully check unit for external damage prior to installation.
Check that the power supply, to which the hoist is connected, corresponds to the information shown on
the type plate on the bottom of the hoist.
