Hackett

• Fitted with a ‘Gussett’ in both jaws of the beam clamp maximising contact between the beam and beam clamp increasing the grip of the beam clamp
• A shackle is fitted to the bottom of the beam clamp allowing ease of connection of an attached hoist
• The beam clamp can be used to an angle of 45 to the vertical. When the angle is moved away from the vertical the working load limit of the beam clamp needs to be reduced by 50%

• The beam clamp can be used to an angle of 45 to the vertical. When the angle is moved away from the vertical the working load limit of the beam clamp needs to be reduced. Please refer to the table opposite - Reduction in working load limits when side loads are applied.

Side loaded across Beam only, as illustrated

REDUCTION IN WORKING LOAD LIMITS WHEN SIDE LOADS ARE APPLIED

The above working load limits and derations have been established specifically for most William Hackett clamps and only apply in overhead beam attachment i.e: DO NOT apply if clamps are to be used for lifting beams.

The tables apply to our clamps only (selected models) and we strongly advise that stress calculations should be carried out (by the user's engineering department) for all support steelwork.

WARNING: All clamps must be correctly applied to the beam by a competent person and fully hand tightened. If in doubt, contact the manufacturer for their recommendations.

NOTE: Clamp model WH-BC (027.200) is not suitable for any side loading as it is of lightweight design.
