The definition of Constant Force® is “The mechanism used to provide a consistent method of absorbing mechanical energy and controlling tension within the system to a constant pre-determined force.”

The application of this principle to fall arrest has created a revolution in system design. This is summarised in the graph below showing the increased load absorption capacity of the Constant Force® post in comparison to a traditional rigid anchor post.

All Latchways systems are CE marked and hold EC Declarations of Conformity. Latchways is also an ISO 9001 company.

Using specialist modelling software our design team will calculate precise loadings and freefall distance to verify technical solutions to arrest a falling person and control the resulting forces (loads). This helps ensure that the most appropriate system is specified for any application.

The capacity of a system and the loads generated in the event of a fall depend on the strength of the structure, supports, components and cable. The Constant Force® post has an integral energy absorbing coil which in the event of a fall will absorb the force generated. The Constant Force® technology ensures that the load will not exceed 10 kN. This allows the post to be fixed to a relatively delicate roof structure without the requirement to attach through the roof to structural steel or purlins.
