Abstract

A wheeled hydraulically actuated haystack loader having a tiltable bed with conveyor chains thereon, such loader including as a part thereof an internal combustion engine driving a hydraulic pump. The loader also includes electrically actuated hydraulic valves for controlling the tilt of the bed and the drive of the chains. The loader can be detachably coupled to a pickup truck by a fifth wheel with the engine operation and the hydraulic valves being controllable from within the operator's cab of the truck by the provision of cabled electric circuit leads connected at one end of the cable to engine controls and to the hydraulic valves, with the other end of the cabled circuits being detachably coupled to an electric switch control box disposed in the operator's cab, whereby the engine's ignition, starter and choke as well as the tilt of the bed and the drive of the conveyor chains can be controlled by the driver of the truck. Detachment and removal of the switch box affords a degree of security against unauthorized operation of the engine and the loader.

Dependent claims

Mobile material handling apparatus and controls therefor, comprising a wheeler trailer, hydraulic fluid actuated means mounted on the trailer for handling material, electrically operated valves mounted on said trailer for controlling hydraulic fluid actuation of the hydraulic fluid actuated means, an internal combustion engine mounted on the trailer and drivingly coupled to a hydraulic pump that is operationally connected to said valves, said trailer being provided with fifth-wheel towing vehicle coupling means at its forward end, said engine including electrically operated components, electrical control means for said valves and for said components, said control means including an array of electric switches and an elongated flexible multiconductor electric cable having its conductors at one end thereof operatively connected to the valves and the engine components and having its conductors at its other end operatively connected to said array of switches, said cable having a length such as to be extendible to position its said other end forwardly of the fifth-wheel coupling means, whereby the valves and the engine components can be controlled from a position remote from both the valves and the engine, and said electrically operated components including an ignition system therefor, and an electric starter therefor, whereby the engine, even when cold, can be started and stopped from said remote position.

Mobile material handling apparatus and controls therefor, comprising a wheeled trailer, hydraulic fluid actuated means mounted on the trailer for handling material, electrically operated valves mounted on said trailer for controlling hydraulic fluid actuation of the hydraulic fluid actuated means, an combustion engine mounted on the trailer and drivingly coupled to a hydraulic pump that is operationally connected to said valves, said trailer being provided with fifth-wheel towing vehicle coupling means at its forward end, said engine including electrically operated components, electrical control means for said valves and for said components, said control means including an array of electric switches and an elongated flexible multiconductor electric cable having its conductors at one end thereof operatively connected to the valves and the engine components and having its conductors at its other end operatively connected to said array of switches, said cable having a length such as to be extendible to position its said other end forwardly of the fifth-wheel coupling means, whereby the valves and the engine components can be controlled from a position remote from the valves and the engine, and plug and jack means detachably coupling the array of switches to the conductor of the cable, whereby unauthorized control of the valves and the engine components is substantially precluded on detachment and removal of the array of switches.
