  • Patent number: 7287949
    Abstract: Disclosed is a mobile apparatus for earth moving and other operations, such as lifting and displacing loads. A frame is displaceable on wheels. An articulated operating arm is supported by the frame for carrying an implement, for instance a container, a digger bucket or wrecking hammer. One or more motors drive the wheels and move the operating arm. The operating arm consists of at least three articulations connected to each other for mutual pivoting on a lying axis. A control member such as a hydraulic cylinder is arranged between each pair of articulations. The third articulation has a greater length than the second one, such that when the articulations are folded against each other, the implement can be freely used at the free end of the first articulation. Thus, the last articulation can be transformed from an articulated arm into a single lifting arm.

    Abstract: A self propelled transportable lift truck (A) having a frame (1) formed by two spaced parallel longitudinal front members and a rear transverse member, at least two front wheels (5, 6) and at least one steerable rear wheel (7), such that the lifting mechanism thereby extends from a most retracted position between the longitudinal members of the frame. The lifting mechanism to raise and/or lower the lifting tines comprises a telescopic lifting arm (4) articulated about a horizontal axis perpendicular to the longitudinal axis of the lift truck. An operator's cab (2) is located to one side of the lifting mechanism; the motive drive unit (3) is housed beneath the lifting mechanism. The lifting mechanism is provided with a yaw control to facilitate the lateral movement of the lifting lines. In addition, the yaw control has, on demand, the capability to automatically self centre the lifting mechanism.

    Abstract: A method of controlling a loader operation using a control system is provided. The system is intended for use on a conventional skid steer loader of the type having either a cab with an integral door for operator access to the cab or a door kit installed thereon. The system includes a door position sensing means for sensing a position of the door of the cab. A disabling means of the system is provided for disabling a lift mechanism of the loader in response to detection that door of the cab is not fully closed by the door position sensing means. The disabling means may comprise a mechanism for coupling the door position sensing means to an existing disabling system of the lift of the vehicle.

  • Patent number: 6588127
    Abstract: A skid loader attachment includes a coupling assembly designed for mounting the device onto a skid loader. The coupling assembly further includes a plate portion that has a plurality of apertures. Each one of the apertures is alignable with an associated skid loader aperture. Each of a plurality of fastening members is insertable into an associated pairing of the aperture and the skid loader aperture. The plurality of fasteners secures the plate portion to the skid loader mounting portion. A tongue portion is operationally coupled to the plate portion. The tongue portion has a top surface that defines a plane. The tongue portion is positioned such that the plane has an angular relationship with a plane defined by a forward surface of the plate portion. The tongue portion is substantially elongate. The tongue portion facilitates movement of material around obstacles such as conveyor belts and rocks.

  • Publication number: 20030108413
    Abstract: A load lifting attachment (30) for increasing the load lifting capacity of a skid-steer loader (62). A lifting mechanism (40) is supported from a C-shaped frame member (32). The frame member has a hard coupling (72) to a boom arm (70) of the skid-steer loader and a pair of caster assemblies (38) at opposed ends. A load supported on the load-bearing forks (42) of the lifting mechanism has its center of gravity proximate the swivel axis of the caster assemblies in order to minimize the resultant loads on the boom arm. The forks extend beyond the wheels (36) of the caster assemblies to allow the device to carry wide loads and to lift loads from a shelf blocking the forward movement of the wheels. An inclinometer (74) is provided to assist the operator in avoiding unstable movements. In one embodiment, the lifting capacity of a skid-steer loader is increased from 1,700 pounds to 5,000 pounds with the addition of the load lifting attachment.

  • Publication number: 20030108414
    Abstract: This invention relates to an outdoor equipment unit such as a walk-behind skid steer loader. The loader has a tracked traction system in which endless tracks are entrained around a rear drive support member and a front support member. The front support member is spring biased forwardly, but can move rearwardly against the spring bias to allow debris that is caught between the front support member to clear itself to help prevent the track from un-tracking. A single control handle having front and rear hand grips located between a fixed grab bar can be rotated and/or twisted to control the traction system. Return to neutral systems ensure that the control handle will return to a centered, neutral position upon release of the control handle by the operator.

    Abstract: The present invention is directed to a material handler that includes a frame, a telescoping boom, a boom extension sensor, a boom angle sensor, and a control system. The telescoping boom is coupled to the frame, pivotable between a lowered and a raised position, and movable between a retracted and an extended position. The boom extension sensor generates a first signal that corresponds to the distance which the boom is extended. The boom angle sensor generates a second signal that corresponds to the angle which the boom is pivoted. The control system receives the signals and displays a cursor located at a position that is based on the first signal and the second signal.
