Members: Rope Abrasion Testing
There is no standardised test for rope abrasion so a method was devised at RopeLab to attempt to compare ropes. It must be stated clearly that it would be very difficult to model or make general assumptions

Members: Pendulum Physics
Pendulums present an interesting study of physics for rope technicians. A simple pendulum is made up of a point mass suspended by a string or rod of negligible mass. In rope systems, the mass of the swinging body
Members: Rig For Lower with a Munter Hitch
Rigging with the ability to lower a load on the main access lines gives rope technicians the ability to deal with some incidents quickly and efficiently. This is known as ‘Rig for Lower’ (RFL) and has been
Members: Human Drop Tests
We have done many drop tests at RopeLab over the last few years. For each test, we must make a decision whether to use rigid steel test masses, semi-anthropomorphic test manikins (like Rescue Randy), or human subjects. Often, we
Members: Falling on Teeth
Technicians regularly use toothed-cam ascenders such as the Petzl Croll. For climbing ropes, the chest-mounted Croll is normally used in conjunction with another handled ascender and foot loop. Technicians are generally taught to ensure they are also attached to this
