Describes something you must do.
Warning
Do not use for the purpose of hoisting people or equipment with
people in it.
Doing so may lead to serious injury or a fatal accident.
Do not let the pulley touch sharp objects or abrasive surfaces.
Doing so will cause the pulley to weaken due to damage or abrasion.
Do not let the sheave rotate continuously at high speeds for long
periods of time.
Otherwise the bearing may abrade due to frictional heat, which may cause
the rotation failure of the sheave.
Do not let the rope fixture touch the pulley.
Doing so may damage the pulley and lead to an accident of a falling hoisted
load.
Do not use during bad weather such as in strong winds.
Doing so may drop the hoisted load and lead to serious injury or a fatal acci-
dent.
Do not apply loads that exceed the working load limit.
Doing so may damage the pulley, drop the hoisted load, and lead to serious
injury or a fatal accident.
Do not perform modifications such as welding or cutting.
Doing so may lead to serious injury or a fatal accident due to a weakened or
broken pulley.
Inspect before use and periodically.
Failure to do so will overlook abnormalities or damage to the pulley, and may
lead to serious injury or a fatal accident.
Attach the hoisted load so that the sheave and hoisted load fixture
are in tandem.
If the load is applied to the pulley from the side, it may lead to serious injury
or a fatal accident due to breakage.
After starting to hoist a load, check that the rope is in the groove of
the sheave.
Failure to do so may drop the hoisted load due to rope damage, and lead to
serious injury or a fatal accident.
When attaching, removing, or transporting a pulley, use slip-resistant
protective gloves and perform work in a stable place.
Failure to do so may drop the pulley and lead to serious injury or a fatal acci-
dent.
Do not apply impact loads.
Doing so may lead to serious injury or a fatal accident due to a broken pulley
or other part, or falling hoisted loads.
Do not ride on top of hoisted loads or pulley equipment.
Doing so may lead to serious injury or a fatal accident due to falls or falling
hoisted loads.
Do not use when there are people within the movement range of the
hoisted load or under the pulley.
Doing so may lead to serious injury or a fatal accident.
When hoisting, stay away from the pulley, rope, and around and
under the hoisted load.
Failure to do so may get your hands or body caught or you may get crushed
under the falling hoisted load, lead to serious injury or a fatal accident.
Do not use the swivel for purposes such as constant rotation.
Doing so may damage the swivel, drop the hoisted load, and lead to serious
injury or a fatal accident.
Caution
Do not use while submerged such as in the sea or water.
Doing so will lead severe rotation failure or strength deterioration due to
adhesion of foreign matter or corrosion.
Do not use or store in the following environments.
· Places with extreme temperature changes
· Places with corrosive or acidic gas
Doing so will cause rotation failure or strength deterioration.
In low temperature environments, check that the sheave is not frozen
before working.
Failure to do so may damage the rope from rotation failure of the sheave due
to freezing.
In high temperature environments, lubricate periodically.
In high temperature environments, depletion of lubricant is severe and if the
lubricant dries up, it will cause the rotation failure of the sheave or the shaft.
Use within the temperature range between -18°C and 66°C.
Using outside of this temperature range will cause rotation failure or strength
deterioration.
