Asian Ladder Race




That is weird race event...A ladder is a vertical or inclined set of rungs or steps.
There are two types: rigid ladders that can be leaned againsta vertical surface such as a wall, and rope ladders that arehung from the top. The vertical members of a rigid ladder arecalled beams (US) or stiles (UK). With a bit of agility, onecan slide down the stiles without climbing down each rung.Rigid ladders are usually portable, but some types arepermanently fixed to buildings.Rigid ladders were originallymade of wood, but in the 20th century tubular aluminium becamemore common because of its lighter weight. Ladders withfiberglass stiles are used for working on or near overheadelectrical wires, because fibreglass is an electrical insulator.
