Page 7: Modification
TYPICAL DOUGHTY LOW PROFILE CLAMP LABEL 5. MODIFICATION The following modifications are allowed to be executed by third parties. Nut replacement: The standard nut and wing-nut shall be replaced by a self-locking nut when Loads are predominantly dynamic. • • Loads are moving and change position. - Page 8 DO NOT lift loads above people without the following precautions Use a Self-locking nut instead of the wingnuts on the eye bolts when loads are predominantly dynamic and loads are moving and change position. Clamps shall be solely used for the range of pipe diameters as stated on the clamp. The use of a clamp on other diameter pipes will lower the working load limit.
