<p>Safety device and safety procedure in the case of a tipping dump body (2) of a truck (1), in which the said dump body (2) through the operation of a control (11) in the driver's cab (4) of the vehicle (1) - and by means of at least one hydraulic or pneumatic lifting cylinder (5) - is designed to be moved between a lowered transport position (6) and a raised tipping position (7), and to assume a floating position, in which the said lifting cylinder (5) is not pressurized and a holding position in which the lifting cylinder (5) is pressurized and the position of the dump body (2) is locked. The invention is characterized in particular in that a detector (13) is designed for detection of the driver's presence in or absence from the driver's cab (4), and that either a presence signal or an absence signal is delivered to the control (11) depending on whether or not the driver is in the driver's cab, and that the control (11) is designed, in the event of an absence signal from the detector (13), to assume the said holding position.</p> |
