Abstract: A load suspension device that can be adjusted, locked, and braced horizontally, by hydraulics, has an extension device for length adjustment, and consists of two supporting parts and a hydraulic operating element having two work chambers, which is connected with one of the supporting parts and supports itself in the other supporting part, and adjusts these relative to one another. There is a pressure line and a tank line, a controller, a measurement sensor disposed on the hydraulic operating element or on the extension device, and a pressure measurement system. The extension device remains braced when the system is without current or pressure or when current or pressure is applied. The device is inexpensive to construct, service and maintain, minimizes damage due to impact of the supporting parts with an obstacle, and avoids impact stresses on the operating element from the hydraulic system.

Abstract: A driver restraint system for straddle carriers has a driver's seat firmly disposed in its infrastructure transverse to the direction of travel. The seat is connected with a seat shell which can be deformed by the forces that occur if the straddle carrier tips over, and which can be displaced in its position and braked with regard to the driver's cabin, in the direction of forces that occur. A belt roller is attached to the seat shell.

Abstract: A windshield wiper system for a vehicle cabin has two drive motors with glass wipers for cleaning a largely rectangular surface area. Two axes of the motors are disposed diagonally in the corner regions of the surface to be wiped. One wiper arm and wiper blades are disposed on these axes, the wiping movement of the wiper blades being guided from a position largely parallel from one side of the surface to be wiped to largely parallel to the other side of the surface to be wiped. The window panes of driver cabins with largely rectangular surface areas can be kept free of dirt at any time under difficult weather conditions over their entire viewing surface so that the operating personnel is given the possibility to view all the activities taking place about the cabin without having to adopt unfavourable positions with respect to their operating equipment.

Abstract: A crane with a boom, on which running tracks for cable carriers are disposed, having two running tracks for the cable carriers, which engage into one another with a positive lock. One running track is connected with the crane or the boom, and the other running track is displaceable on the crane or the boom.

Abstract: A method for determining a position of a target is described that includes establishing a reference target position and a measuring location position and measuring a range to the target, an azimuth angle to the target, and an elevation angle to the target. The reference target position, the measuring location position, the measured range to the target, the azimuth angle to the target, and the elevation angle to the target are utilized to calculate a position of the target.

Abstract: A biased support for booms that can pivot about a pin, for pivoting travel tracks for vehicles that run on rails, such as trolley travel tracks on booms. The booms are mounted to pivot via pins, the lock on the boom and slide plates on the upper and lower bearing points of the lock. At least one of the two slide plates in the upper bearing point is mounted elastically, so that when the boom is pivoted into the operating position, the entire lock is biased vertically and the pin is relieved of stress.
