Abstract
The invention relates to a heavy goods vehicle, specially for the transportation of slag, comprising a loading platform for vessels containing slag, fitted with a gripper device for receiving and moving a standardized load-bearing implement which can be actuated by a hydraulic cylinder (11) and an anti-tilt device (15) for the vehicle which operates during movement of the load-bearing implement. The vehicle is also fitted with at least one hydraulic cylinder (11) with switches. Upon a given stroke of the piston, at least one switch engages a device detecting hydraulic pressure inside the cylinder on one or both sides of the piston. The pressure detection device triggers a security device, e.g. a display for the driver or an operation blocking device.
Claims10
A heavy-duty vehicle, comprising:
- a frame;
- a gripping device mounted on the frame for picking up and moving a standardized load carrier;
- hydraulic cylinders operatively connected between the frame and the gripping device for actuating the gripping device, the cylinders each having a piston and a piston rod;
- tipping prevention means for preventing tipping of the vehicle during movement of the load carrier;
- a switch provided on at least one of the hydraulic cylinders;
- a pressure detection device operationally connected to the switch so that the pressure detection device is engaged at a predefinable stroke of the piston to determine hydraulic pressure in the cylinder on at least one side of the piston;
- and
- a safety device operatively connected to the pressure detection device so that the pressure detection device switches on the safety device when a reference value for the pressure is exceeded.
A heavy-duty vehicle for transporting slag, comprising:
- a loading platform for slag vessels;
- a frame;
- a gripping device mounted on the frame for picking up and moving a standardized load carrier;
- hydraulic cylinders operatively connected between the frame and the gripping device for actuating the gripping device, the cylinders each having a piston and a piston rod;
- tipping prevention means for preventing tipping of the vehicle during movement of the load carrier;
- a switch provided on at least one of the hydraulic cylinders;
- a pressure detection device operationally connected to the switch so that the pressure detection device is engaged at a predefinable stroke of the piston, hydraulic pressure in the cylinder on at least one side of the piston;
- and
- a safety device operatively connected to the pressure detection device so that the pressure detection device switches on the safety device when a reference value for the pressure is exceeded.
