MULTIPURPOSE MOTOR CAR FOR APPROACHING MAXIMALLY HIGH PLACE WORKING BASE TO OBJECT TO BE REPAIRED BY EXTENDING AND CONTRACTING TOTAL LENGTH OF HIGH PLACE WORKING BASE

摘要

PURPOSE: A multipurpose motor car is provided to load or unload timbers by a knuckle crane and to facilitate a high place work for a signal lamp and a car line by moving a high place working base with an operator. CONSTITUTION: A first transfer link bar(20) is combined across a first fixing link bar(10) joined movably on a base plate(11) to move along a guide rail(23). A second fixing link bar(30) is combined movably to a high place working base(60) and the first fixing link bar. A second transfer link bar(40) united and moved along the guide rail of the high place working base and the first link bar is combined across the second fixing link bar. The height of the high place working base is regulated by folding and unfolding plural link bars according to an operation of a lift cylinder(50) connected between the first and second fixing link bars. A transfer plate(64) of the high place working base is installed slidably in a fixed plate(61) forming the bottom surface. The transfer plate is coupled with the fixed plate by an expansion cylinder(66) and selectively extended or contracted in a width direction by the operation of the expansion cylinder.
