A railway zig zag or switchback is a railway operation in which a train is required to switch its direction of travel in order to continue its journey. While this may be required purely from an operations standpoint, it is also ideal for climbing steep gradients with minimal need for tunnels and heavy earthworks. [ 1 ]
Static ropes are designed to allow relatively little stretch, which is most useful for applications such as hauling and rappelling. Dynamic rope is used to belay climbers, and is designed to stretch under a heavy load to absorb the shock of a fallen climber. Dynamic ropes manufactured for climbing are tested by the UIAA. A test of "single ...
Josiah White and Erskine Hazard-founding partners of the Summit Hill & Mauch Chunk Railroad Pisgah Mountain and the topography of the Summit Hill and Mauch Chunk Railroad. The Mauch Chunk Switchback Railway, also known as the Mauch Chunk and Summit Railroad and occasionally shortened to Mauch Chunk Railway, was a coal-hauling railroad in the mountains of Pennsylvania that was built in 1827 and ...
[2] [4] Single ropes must sustain at least 5 such falls before breaking, and a rope that can sustain more than 9 falls is considered a 'multifall' rope. [4] In practice, climbing ropes rarely if ever break due to a fall alone- all documented rope failures involve the rope being cut or damaged, for example by abrasion against a sharp rock edge. [2]
A climber and a belayer using a climbing rope. A climbing rope is a rope that is used in climbing.It is a critical part of an extensive chain of protective equipment (which also includes climbing harnesses, anchors, belay devices, and carabiners) used by climbers to help prevent potentially fatal fall-related accidents.
Modern single-rope technique uses specialized devices for both descent and ascent, and low-stretch kernmantel rope of 8-11 mm diameter. Descent (abseiling or rappeling) uses various forms of friction brake to control speed. The most commonly used are the Petzl Stop (self-locking) and Bobbin, and rappel racks. For safe single-rope technique ...
