GENERAL SAFETY INSTRUCTIONS
■ Check the clamp before use – do not use a defective plate clamp.
■ Ensure that the clamps are suitable for the thickness of plate to be lifted.
■ Never exceed the maximum or minimum thickness for which the clamps are designed.
■ Put the clamp onto the plate as far as it will go.
■ Do not use clamps at an angle to the edge of the plate or for lowering from vertical to horizontal, or vice-versa, unless they are designed for the purpose.
■ Keep oil, grease and similar contaminates away from jaws which use a friction grip material to hold the plate.
■ Never use lifting plate clamps on hard or polished plate unless they have been specifically designed for that purpose.
■ Take great care to ensure the plate is fully supported before attempting to release the clamp.
■ Keep all persons clear of the danger zone and remember that a falling plate can ‘glide’ sideways. A large thin plate is likely to glide further. Also the higher it falls from, the bigger the danger zone.
■ Never overload a plate clamp
■ Never use a single clamp – always in pairs
■ Never exceed the permitted maximum or minimum thickness
■ Never substitute an endless loop for a two-leg sling or vice versa
■ Never exceed the permitted range of sling leg angles
■ Never use the cam-less type if the plate can sag
■ Never attempt to rotate from the horizontal to the vertical with this type of clamp
