Simple, accurate, cost effective height limiting system, suitable for self-installation. The 1HLI height limiter is designed to protect workers from overhead danger when operating in restricted conditions, it is often difficult for the operator to judge the actual height of the machine or the position of the booms from the cab. This can result in collision with roofs, walls, bridges and gantries or overhead wires and  many cases causing expensive damage to the machine, third party claims for structures around the machine while also protecting any personnel on site.

APPLICATION: For use in the construction and utility maintenance industries for use on machines such as excavators, wheel and backhoe loaders, telehandlers and other articulated machines operating in restricted conditions.

HOW IT WORKS: The machine operator is able to define a pre-set limit of the machines boom on the 1HLI operator station, preventing movement of the boom outside of the pre-set limit. This entry level height limiting system monitors the angle of a single boom and provides a motion cut signal output when the angle is exceeded.
