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 damage to the sheave and shaft
and rotation failure for the sheave.
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.
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 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.
Doing so will cause the lubricant to dry up and wear out the sheave
and shaft due to frictional heat.
Use within the temperature range between -18℃ and 66℃.
Using outside of this temperature range will cause rotation failure or

③Put it inside the hook while
tilting to the side so avoids
the hook tip.
●Rotation of sliding parts
○The swivel (or hook) and sheave
rotate smoothly.
●Safety latch opening and closing
○The safety latch opens and closes
smoothly to its specific positions.
○The spring is not permanently damaged.
The nut is not loose or defective.
●Perform periodic inspection at least once a year.
●If you use the product under harsh conditions such as frequent hoisting
of loads equal to the working load limit, impact loads, or intense rolling,
perform inspection early because the parts will wear out substantially.
●For periodic inspection, inspect all of the items in
Inspection before use ,
perform maintenance, and check the dimensions of each part. If the
dimensions are 10% different from the original dimensions or the
dimensions in the catalog, replace the part or product.
(Refer to for the dimensions.)

・
Products that are deformed, cracked, or worn out
・
Products with signs of corrosion such as rust stains or
galvanic corrosion
Doing so may lead to serious injury or a fatal accident due to
falls or falling hoisted loads.
Do not let the product touch other types of metal for long
periods of time.
Doing so will cause corrosion.
When disassembling the pulley for sheave replacement,
remove it from high places and disassemble on the ground.
Failure to do so may drop the pulley and lead to serious injury or
a fatal accident.
When replacing parts, use ASANO-specified parts.
Failure to do so may result in lower functionality of the pulley
due to incompatible parts.
If it does not go into its specific positions even if you apply
grease, the cause may be deformation or bending.
Discontinue use and replace the product.
If rotation is poor, not centered, significantly rattles, or if rotation
stops, discontinue use and replace the part or product.
If the spring is significantly damaged and does not go into its
specific positions, replace the safety latch.
Inspect before using the pulley.
Using the product when there is a problem accelerates the
damage and may lead to strength deterioration, damage to the
product, or an accident of a falling hoisted load.
In the unlikely event the pulley deforms or breaks and a load is
hanging in midair, first take down the hoisted load, unload the
pulley, and take safety measures to prevent secondary disaster.
