Working and transportation machine

Abstract

Abstract PURPOSE: To provide legs for a working and transporting machine, which have high effectiveness and grade of freedom when functioning and are neatly collapsible on the rear of an under the base plate when not in service, by installing outriggers at the four corners of the base plate each through a hydraulic cylinder in such an arrangement as giving an appearance of spindle and by providing possibility of front legs being stored under the plate and the rear legs on the rear part of the plate. CONSTITUTION: During transport of objects, the four outriggers 28A are accomodated collapsed in a channel 29 at the front of the base plate 1a and the rear outriggers 29B, in a channel-shaped groove 52 provided in the columns 47 which are installed upright on the rear part of the base plate 1. In this condition an object 75 is placed on the base plate 1 and transported. When the intended position is reached, links of the outriggers accmodated are drawn out and hydraulic cylinders 43, 60, etc. are put into operation so as to hold the object at the intended height. Because of the construction of outriggers in an appearance of spindle legs, their stretches and the lookdown angle of the head of machine can be changed in any desired way, and further the hydraulics assure quick operation of opening and closing legs as well as safe and easy work.
