CAUTION: NEVER
EXCEED THE WORKING LOAD LIMIT
Read important
information below and also on pages 3 and 4.
READ THE FOLLOWING
WARNINGS AND SAFETY INFORMATION CAREFULLY.
EVEN EXPERIENCED
PERSONNEL NEED TO UNDERSTAND THIS INFORMATION.
Failure to follow
warnings and instructions can result in serious injury or death.
|
|
| |
Blocks
are devices used for lifting or lowering loads, or for changing direction
of the pull on the line. They consist of a sheave, two side plates,
and an end fitting which is either a hook with a latch or a shackle. |
|
WARNING
|
Improper
use or set-up of a block system can cause a load to slip or fall,
resulting in serious injury or death.
|
A block
assembly should always be rigged by someone with training and experience
in designing and assembling these systems. If you do not understand
how to rig properly or how to operate block systems, seek professional
assistance.
|
Also,
the following statements should always be followed in order to prevent
serious injury or death.
|
| |
Keep
out from under a raised load.
|
| |
Stay
out of the line of force.
|
| |
Keep
hands and body away from block sheaves, hooks, and shackles.
|
| |
Keep
hands and clothing away from "pinch points" where the rope meets or
touches block parts or loads.
|
| |
Do
not side load blocks.
|
| |
Never
lift personnel with a hook block.
|
| |
Always
be alert in areas where loads are lifted or moved with block assemblies. |

IMPORTANT SAFETY
INFORMATION
|
|
|
ASSEMBLY:
A number
of potential hazards exist when working with blocks. These hazards
can cause serious harm to both humans and property. However, these
hazards can be avoided if the block systems are assembled, used,
and maintained properly. The following directions should ALWAYS
be followed in order to prevent serious injury or death.
1. Always make
sure that the hook supports the load. The latch must NEVER support
the load.
2. Always check
for wear or damage before rigging block systems. Check for cracks,
rust, corrosion, deformation, intentional alterations, chips, warps,
or any other physical sign of damage or wear. When in doubt about
the extent of wear or damage to a product, take the product out
of service immediately. Only laboratory tests can determine the
fitness of a damaged or worn part. Thus, you may not be able to
tell whether a part with any amount of damage is safe to use. Discard
any part that appears worn or damaged.
|
USE:
| 1. |
Know and follow
OSHA rules.
|
| 2.
|
Know the weight
of the load and the line pull required.
|
| 3. |
Make sure that
the correct wire rope grade and diameter is used. Consult wire rope
section of catalog for information.
|
| 4. |
Never exceed the
Working Load Limit (WLL). The Working Load Limit indicated is the
greatest force or load a product can carry under usual environmental
conditions. Shock loading and/or extraordinary conditions must be
taken into account when selecting products for block systems and especially
in determining the Working Load Limit for a specific application.
|
| 5. |
The Working Load
Limit of a product is affected by many factors. Among these are: Overloading,
misuse, intentional abuse or alteration, corrosion, deformation, operation
in extreme environments, and simply wear. In order to determine whether
the product can continue to be used at the published WLL, regular
inspections must be performed. These inspections also will determine
whether a product must be withdrawn from service.
|
| 6. |
Avoid side loading
blocks. These products generally are intended for tension or pull.
Side loading must be avoided, as it exerts additional force or loads
which the product may not be able to withstand.
