  • Articulated waist terrain vehicle
    Patent number: 4506792

  • Wheeled working vehicle with crane
    Patent number: 4505396
    Abstract: In a working vehicle including a crane (21) for handling loads and a driver's cab (11), both crane and cab are rotatably mounted on the vehicle, each about its vertical axis, and controlled such that a turning angle .beta. of the crane results in a turning angle .alpha. of the cab, .alpha. being an optional function of .beta., e.g. half of .beta.. The driver can thus carry out all the working operations desired for the crane without having to turn his head uncomfortably.
