Aerial work platforms are essential when there is no possibility of using telescopic booms or articulating platforms due to their large dimensions or weight – on slope surfaces or indoors – airports, train stations, atriums, shopping centers, etc. “Spiders” are very portable, even low ceilings are not a problem. Working height of the most “modest” machines starts from 9 m and the biggest ones reach 48 m.The most remarkable constructive innovation implemented in new platform is boom with two articulated and telescopic sections in aluminium for better aerial agility.
