On some telescopic boom machines the maximumreach that can be achieved may varythe actual load in the cage.This is achieved by the use of a LOADMAMANGEMENT SYSTEM which will prohibitfunctions when rated SWL has been achievedgiven boom length/radius.The functions which are prohibited are BOOM DOWN& TELESCOPIC OUT: thus only safe movements arepermitted eg: BOOM UP & TELESCOPIC lN. Swingis not restricted.

Philippine Societv of Safetv PractitionersMiddle East ResionCAUTION: - Withthese systems, it ispossible if the taskrequires removal ofgoods from thestructure into the cagethat, if the positionand weight in thecage is close to themaximum, anoverload condition willoccur without warning.
