  • Patent number: 8016074
    Abstract: A platform for an aerial lift enables unobstructed access to a work area adjacent the platform. The platform includes a floor structure with front and rear sides and ends, and a safety rail disposed along at least the front side. The safety rail includes an entry gate. A lift gate is pivotably attached to the safety rail and pivotable between a closed position and an open position. The lift gate includes a gate rail extending along the rear side of the floor structure and a pair of lift rails connected between the gate rail and the safety rail. The gate rail is pivotable relative to the lift rails between an extended position and a retracted position. In this manner, the lift gate can be raised without the gate rail impacting the work surface.

  • Patent number: 7766596
    Abstract: An attachment for a telescopic material handler supplies five degrees of freedom (DOF) for the task of picking, manipulating and aiding in the installation of vertical and horizontal wall cladding and other construction materials. The cladding can be of a size up to 1.3×8.0 m and a mass of 350 kg. The control and positioning of the load is accomplished through standard operation of the telehandler in conjunction with wireless control of the five DOF of the device. Hydraulic power for the device functions may be supplied through the telehandler auxiliary circuit. The auxiliary flow also powers a hydraulic generator, which supplies the device with electrical power for both system logic and control and vacuum generation. The cladding panels are handled by the vacuum system.
