BLACK BEAR HOIST
6. Cautions
6.1 Preliminary Inspection
1) Do not use the hoist if the Safety Latch of hook has been broken/damaged.
2) Safety Latch must be completely closed before use.
3) There should not be any damages or deformation on the hook and chain.
4) All the fixed bolts and nuts should be attached and screwed in tightly.
5) The hook should revolve easily and smoothly.
6) There should not be any dirt or other unusual substances on the hoist.
6.2 Prohibition of Overload
1) Never lift a load that is heavier than the rated capacity of the hoist.
2) Always check for the capacity, written on the name plate of the hoist.
3) All Black Bear hoists are manufactured with consideration of its working area conditions and are tested
with a greater load than its rated safe working load.
4) However, overloading hoists is extremely dangerous as it is considered the same as removing safety
device. ALWAYS operate hoists within the safe working load.

6.3 Safety Latch of Hook
1) When loading the bottom hook, devices like wires and ropes and slings are often used. The Safety
Latch on the hook prevents these other devices to not come off from the hook creating a dangerous
lifting situation. Do NOT detach the Safety Latch from the hook.
6.4 Prohibition of Hoist/Trolley Remodeling
1) Voluntary remodeling of the hoist/trolley by the user is strictly prohibited.
2) Use of this hoist/trolley as elevator (for both passenger and freight) is strictly prohibited.
6.5 Cautions During Operation
1) Make sure of the safe working load of the hoist (indicated on the trolley). When overloaded, it
could result in serious injury or damage to an operator.
2) Only use to lift vertically.
3) Keep the safe distance and move the hoist slowly along the beam.
4) Never place your hands/feet under the load. Always be aware of overhead loads.
5) Never hang a load with greater capacity than that of the hoist. Check capacity of the hoist before
use.
6) The hoist must hang centrally under the beam or under its suspension point.
7) Do not swing/shake a suspended load. Do not cut or weld a load that is suspended in the
hoist.
8) Lifetime of the hoist will be shortened if it is exposed to rain. If used outside, cover the entire hoist
to avoid rain.

6.6 Lifting
1) Never use lifting slings or connecting hook (rope/wire/suspending chains) that is not rated
higher capacity than the load being lifted. Always check for any damages/deformation on lifting
slings/connecting hook before use.
2) To lift load safely, lifting slings with proper length and capacity should be used. Use lifting slings
that have sufficient load capacity for every operation.
3) Never suspend more than 1 load on a single hook.
4) Do not place any parts of the body inside hook (ex. hand, fingers).
5) Do not hit or apply shock on hook.
6) The load must be properly suspended (by rope/wire/suspending chains) in the saddle of the
hook. If load is placed incorrectly, dangerous situation may arise causing load to drop. Always
check if load is suspended safely.
7) Never suspend load on the tip of hook.
8) Always balance the loads. Ropes/wires/suspending chains must not
be tangled, slanted, or twisted.
9) Never use hoist as support of fixtures.
10) Safety Latch must be completely closed when lifting sling or wire
is suspended on hook. If Safety Latch does not close due to thickness
lifting rope or sling, it must be replaced with proper size/capacity one.
11) The angle (θ) of the 2 Lifting Sling or ropes should not be big.
If angle (θ) in the picture is excessively wide, there are possibilities
of parts breaking and load dropping as the weight applied gets
bigger. The angle (θ) of slings (ropes) should be less than 60°.
12) Never wind up Load Chain around load. If wound around, Load
Chain could crush edges of the load. It could also decrease
the strength of chain causing danger.
13) Chain must be used only in perpendicular directed loads.
Slanted direction is dangerous because load balance is lost.
Chain has weak horizontal pulling strength, so only use in
perpendicular directed loads.

BLACK BEAR HOIST
6.7 Cautions During Lifting/Hoist Operation
1) Pay full attention to the load and the surroundings at all times when operating the hoist. The
hoist must not be loaded when not in use.
2) Be sure everyone is clear of the load path. Do not lift load over people.
3) Never use the hoist to lift or lower people. Do not stand or sit on a suspended load.
4) Never place your hands/feet under the load. Always be aware of overhead loads.
5) Never lift a load with greater capacity than that of the hoist. Check capacity of the hoist before
use. Also never pull or load from the side.
6) Do not operate hoists with twisted, tangled, or damaged chains.
7) Be certain that Load Chain is tightly pulled. Check the balance of the load by hoisting a little bit.
8) The hoist must hang centrally under the beam or under its suspension point.
9) The load/sling must be properly suspended in the saddle of the hook. Never suspend the load/sling on
the tip or end of the hook.
10) Do not swing/shake a suspended load. Do not cut or weld a load that is suspended in the
hoist.
11) Lifetime of the hoist will be shortened if it is exposed to rain. If used outside, cover the entire hoist
(and chain basket) to avoid rain.
12) It is very dangerous to lift a load by using 2 hoists at the same time as the weight might shift to
one side. Be certain that load is properly balanced and kept horizontal.
13) Stop the hoist immediately if chains are making unusual or excessive noise, blocking over the
load, or binding occurs.

1) Load Chain Test
When the chain (which the load will be suspended on) is rusted
or stretched out, replace the chain immediately! Rusted/stretched
chain causes potential danger/problems in operating the hoist.
Notice
Measure the diameter and inside length of the chain. If the measured lengths go over the
allowable limit, replace the chain. [ Refer to 7.5.1 ]
2) Hook Inspection
The hook will not be deformed or broken if it is used within the safe working load and complied
to this manual instructions. However, when used over long period of time, overloading the hook
may occur. Therefore, be certain to inspect the hook regularly. Replace the hook if the hook
gate is open or seems deformed in any other way.
Notice
Measure the hook opening length. Replace the hook if the length go over the allowable limit.

7.2.3 Annual Inspection
1) Disassemble the gear box and check for abrasion/damage of gear parts. Replace them if necessary.
2) Check for abrasion/damage of ratchet, stopper (pawl), or brake lining. Replace them if necessary.
3) When the inspection is completed, assemble the hoist and fill the lubricating grease.
4) Check for any unusual noise, etc. by hoisting/descending the hoist about 40-50cm for 2-3 times
without any load suspended. Then try the same inspection again with a load suspended, and check for
any sliding and other problems. Use the hoist if everything is working properly.
