Include slow blow type fuses or inverse trip time circuit breakers to permit the hoist to start and accelerate the
load.
Include a disconnecting means capable of being locked in the ‘open’ position.
3.4 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.
3.5 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.
3.6 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).
3.7 Load Chain
The chain should feed smoothly into and away from the hoist and hook block (¼ 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.
3.8 Load Chain Lubrication
Always lubricate load chain weekly or more frequently depending on 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. Never use used motor oils as a chain
lubricant. Only use Lubriplate Bar and Chain Oil 10-R or equal lubricant as a lubricant for the
load chain.
Suspending the hoist from an inadequate support could allow the hoist and load to fall
and cause personal injury and/or property damage. 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.
