Deviation point load calculator
Utilise the calculator provided below to determine the force exerted on a deviation point.
Simply input the values for the deviation angle, as illustrated in the image, and the weight of the load on the rope. This calculation method can also be employed to estimate the forces acting on a parapet where ropes may traverse.
It's essential to recognise that the recommended loading of a deviation point depends on the angle. In situations involving rope access or height safety, employing rope deviation techniques around obstacles may be necessary. However, it is highly advisable to maintain deviation angles at 60 degrees or lower. As depicted in the illustration, angles exceeding 60 degrees lead to a higher load on the anchor compared to the load on the end of the rope. Deviation angles surpassing 60 degrees can pose significant risks when working at heights, potentially resulting in system overloads and reduced safety against impact forces.
Note:
Please be aware that in rope access, deviation angles over 20 degrees may require a two-point setup for added safety.

Deviation point load calculator
It is crucial to calculate access deviation loads for several reasons:
Safety: Understanding the forces exerted on deviation anchors is vital for ensuring the safety of workers engaged in rope access or height safety tasks. By accurately calculating these loads, we can prevent overloading of anchor points, which could lead to system failures and potential accidents.
Equipment Integrity: Overloading deviation anchors can cause excessive stress on equipment, leading to premature wear and tear or even structural damage. By calculating access deviation loads, we can ensure that our equipment operates within safe limits, prolonging its lifespan and reliability.
Compliance: Many safety regulations and standards mandate the calculation and adherence to safe working loads for anchor points and rigging systems. By accurately calculating access deviation loads, we demonstrate compliance with these regulations, reducing liability and ensuring a safe working environment.
Efficiency: Understanding the forces involved allows us to design and implement efficient and effective rope access systems. By optimising anchor placements and rigging configurations based on calculated loads, we can maximise worker safety while minimising unnecessary equipment and setup.
