Abstract

In one exemplar embodiment, an apparatus for handling and conveying materials is disclosed having a movable chassis, a longitudinally extendable conveyor assembly mounted on the chassis, the conveyor having a projecting loading end capable of limited longitudinal and arcuate vertical movement to a position immediately adjacent the location of the material being handled. An articulated boom assembly is rotatably mounted on the chassis with the movable free end carrying a pushing and pulling blade for loading the material unto the loading end of the conveyor.

Dependent claims

An apparatus for handling loose materials such as gravel, sand or the like, comprising

a generally inverted U-shaped chassis having an upper horizontal base surface,
vehicle drive means carrying said generally inverted U-shaped chassis for providing ground support and propulsion therefor,
a platform rotatably mounted on said upper horizontal base surface of said chassis,
means for horizontally rotating said platform with respect to said chassis and vehicle drive means,
an elongated articulated boom means mounted on said platform for rotation therewith and for longitudinal extension beyond said chassis and vehicle drive means, said boom means having a free extending end,
longitudinally extendable conveyor means mounted on said chassis below the level of said platform and adapted for limited arcuate vertical movement with respect thereto, said conveyor means including
a generally rectangular cradle member,
suspension means cooperating with said chassis and said cradle member for suspending said cradle member from said chassis and permitting at least limited arcuate vertical movement therebetween,
conveyor assembly disposed longitudinally in said cradle member and cooperating therewith for permitting longitudinal movement with respect thereto, said conveyor assembly having a loading end projecting from said cradle member and said chassis,
driving means for moving said conveyor assembly longitudinally with respect to said cradle member and moving said loading end longitudinally with respect to said chassis, and
positioning means cooperating with said cradle member and said chassis for arcuately moving said cradle member in a vertical plane with respect to said chassis and positioning said longitudinally movable loading end into contact with the loose materials for cooperating with said free extending end of said boom means, and
material handling means mounted on said free extending end of said boom means and cooperating with said conveyor assembly loading end for moving the materials unto said conveyor means.
