Abstract
A lifting vehicle includes: a chassis, a telescopic boom articulated to the chassis and provided at a distal end with a mounting for attaching implements for handling a load, a control cab, at least one cab tilt actuator configured to vary a tilt angle of the cab with respect to the chassis, and an automatic tilt adjustment system configured to control said cab tilt actuator to automatically vary a tilt angle of the control cab with respect to the chassis as a function of the position of the load.
Claims7
A lifting vehicle, comprising:
- a chassis,
- a telescopic boom articulated to the chassis and provided at a distal end with a mounting for attaching implements for handling a load,
- at least one lifting cylinder arranged between the telescopic boom and the chassis and configured to control a tilt angle of the telescopic boom with respect to the chassis,
- a control cab carried by the chassis, wherein the control cab can be tilted with respect to the chassis,
- at least one cab tilt actuator configured to vary a tilt angle of the control cab with respect to the chassis, and
- an automatic tilt adjustment system configured to control said at least one cab tilt actuator to automatically vary the tilt angle of the control cab with respect to the chassis as a function of a position of said load,
- wherein said automatic tilt adjustment system comprises:
- a length sensor configured to detect an extension length of said telescopic boom,
- an angle sensor configured to detect the tilt angle of the telescopic boom with respect to the chassis,
- a cab tilt sensor configured to detect the tilt angle of the control cab with respect to the chassis, and
- an electronic control unit configured to receive information supplied by the length sensor and angle sensor and to control said at least one cab tilt actuator according to information supplied by said length sensor and angle sensor.
