  • Known safety clamps configured to be used for a vertical or inclined section is provided with a braking mechanism.
  • the braking mechanism typically engages with the safety rail in a resting state and so prevents the safety clamp from sliding downwards along the safety rail. If a workman were to slip the safety clamp would arrest the fall as the weight of the workman would cause the braking mechanism to further engage with the safety rail.
