Abstract
Safety device and safety procedure in the case of a tipping dump body ( ) of a truck ( ), in which the dump body ( ) through the operation of a control ( ) in the driver's cab ( ) of the vehicle ( ) and by means of at least one hydraulic or pneumatic lifting cylinder ( ) is designed to be moved between a lowered transport position ( ) and a raised tipping position ( ), and to assume a floating position, in which the lifting cylinder ( ) is not pressurized and a holding position in which the lifting cylinder ( ) is pressurized and the position of the dump body ( ) is locked. The device includes a detector ( ) that is designed for detection of the driver's presence in, or absence from the driver's cab ( ), and that either a presence signal or an absence signal is delivered to the control ( ) depending on whether or not the driver is in the driver's cab. The control ( ) is designed, in the event of an absence signal from the detector ( ), to assume the holding position.
