The system shall bepurpose built to provide smooth take<strong>of</strong>f,variable speed range and smoothslowdown (buffering system) based onthe criteria laid down under EN 1777 &EN280 or any other relevant standardsapplicable for these kind <strong>of</strong> vehicles.3 Clause No 5.3 There shall be two or three booms: thefirst main boom with telescopicextensions providing direct movementand the other articulated boom withvertical movement <strong>of</strong> approx. 180degrees, there shall preferably a thirdboom with vertical movement <strong>of</strong> approx.130 degrees to enable a person climbdown from the cage to the ladder on thesecond boom.
