Abstract: The invention relates to a vehicle lifting platform for lifting vehicles, in particular motor vehicles or similar, comprising load receiving means, a drive device which raises and lowers the load receiving means and which can be controlled by a drive control, also comprising an energy accumulator which supplies energy to the drive control and to the drive device. A rapid replacement device is provided on the vehicle lift platform enabling the energy accumulator or energy accumulators to be arranged in an exchangeable manner.

Abstract: The invention relates to a lifting device for raising and lowering loads and to a method for testing and monitoring the lifting device (11), comprising a lifting unit (14) and a support (16) guided by the lifting unit (14), on which support a load-accommodating means (17) can be arranged, a drive unit (25), which moves the load-accommodating means (17) up and down, at least one energy store (29), which supplies at least the drive controller (25) with energy, a charging unit (36) for the at least one energy store (39), at least one actuator (23, 31) and/or at least one sensor (30), by means of which at least one stroke motion of the load-accommodating means (17) can be monitored, and at least one indicating device (49), which indicates at least individual operating states of the lifting device, wherein a drive controller (25) has a control circuit board (33), to which connections (41, 43, 46, 48) of the at least one energy store (29), of the charging unit (36), of the drive unit (15), which comprises at least

Abstract: The invention relates to a lifting device for lifting loads, in particular vehicles, comprising load receiving means which can be raised and lowered by means of at least one lifting element, and a drive device which is controlled by a drive control. Said lifting device is characterised in that an energy accumulator, which supplies the drive control and the drive device with energy, is provided on the lifting element, the load receiving means or inside a working area of the load receiving means or the lifting element.

Abstract: A tire testing device comprising an air pressure control means for changing the tire pressure of a wheel, a test head and a computer, which prior to and after a change in the air pressure produce an interferogram of the tire surface and convert the interferogram into a modulo-2.pi.

Abstract: A method and apparatus for checking the state of the chassis of a motor vehicle, wherein the motor vehicle is brought onto a position holding means spaced over a support and then the position holding means is removed so that the motor vehicle falls with its front or rear axle in free fall on the support, and wherein (1) the spacing between the position holding means and the support, which corresponds to the height of fall of the motor vehicle, is selected so that it corresponds essentially to the residual spring deflection (distance between wheel axle and buffer stop) predetermined by the design of the motor vehicle but does not exceed this, (2) the position holding means is removed at least as quickly as the particular wheel or wheels of the motor vehicle to be tested would fall under the action of the force of gravity and the simultaneous action of the relaxing spring present between wheel and body, ignoring the oppositely directed action of the shock absorber and the frictional forces (for example in the a
