Pre-Work Check; Method Of Use And Slinging Work - REMA WF Série Mode D'emploi

2. Pre-work Check

 Do not use clamps that are not suitable for the work method.
 Do not use clamps that malfunction or are deformed, cracked, worn or otherwise abnormal.
 Do not use clamps to suspend loads made of the following materials: Brittle materials, high hardness
materials, low hardness materials, very low strength materials, or members whose grip surfaces are
inclined at an angle of 10 or more with respect to each other in the slip-off direction.
 Check the type, basic working load, opening dimensions, and periodic inspection "completed" stamp
indicated on the body of each clamp.
 The magnitude of the suspension load must be within the allowable range of the basic working load of
the clamps to be used.

The sheet thickness of the suspension load must be within the allowable range of the clamps to be used.
 Do not remove tags or caution labels attached to clamps, or use clamps with these indications in an
illegible condition.
 Do not use clamps under the following environmental conditions: When the temperature of the load to be
suspended is more than 150C or less than -20C, in a location where there are chemical reagents such
as acids or alkalis, or where the atmosphere is acidic or alkaline.

Be sure that the sling to be used with clamps is suitable for the type of slinging work.

3. Method of Use and Slinging Work

 Do not use a clamp to suspend a load at one point only.
 Do not use clamps to suspend loads in any of the following ways: Two loads clamped together, insertion
of an object between the clamps and the load, two loads suspended at different heights, two loads
suspended together, or horizontally gripped loads.
 Do not use clamps to extract long sheet piles or suspend them in the lengthwise direction.
 Do not use clamps when there is a strong wind or when danger is anticipated.
 Do not use clamps to suspend the bucket of a backhoe.
 Install two or more clamps at positions where balance is maintained, in order to ensure stability of the
suspension load.
 Ensure that the suspension angle and the attachment width angle of each clamp are within the specified
range that matches the type of clamp.
 Insert the suspension load to the rear of the open part of the clamp.
 When using a clamp with a locking device, be sure to apply the lock.
 Do not use clamps to suspend a load whose grip surfaces have oil, paint, scale, rust, or other matter
adhering to them.
 Do not drop or drag clamps along the ground.
