A safety clamp 11, which in use is clamped around a vertical scaffolding pole 102, comprise a collar section 201 which surrounds the pole and a levered braking means 211. The levered braking means comprises first and second brake arms (302, 303, Fig 3) having first and second brake pads (307, Fig 3), 310 and a central brake arm (306, Fig 3) which is pivoted to the collar section. The first brake pad is pivoted on the first brake arm and located in a brake arm housing 210 of the collar. The levered braking means acts to stop the motion of the safety clamp along the pole in either direction. This is useful in the situation where the pole has buckled and bent over as it stops the safety clamp travelling back up the pole, in direction 602 . An operative (106, Fig 1) is attached to the safety clamp via lanyard (109, Fig 1) and karabiner 110. |
