Abstract: An AWP boom is coupled to a platform rotator through a novel load sensing linkage system which provides both structural support and load sensing capabilities of an attached platform support structure. The load sensing linkage system includes an upper flex plate and a lower flex plate and a single load cell for load sensing capabilities. The flex plates provide for stiffness in all directions except where necessary for load sensing.

Abstract: A leveling system for a structure to be leveled is provided. At least one linear accelerometer is mounted to measure acceleration in a principal plane of motion of a lift structure. An angular rate sensor is mounted to measure angular velocity about an axis perpendicular to the principal plane of motion of the lift structure. An electronic control module is configured to use measurements from angular rate and accelerometer sensors to produce a level angle output. The level angle output is used to adjust and control a level angle of the structure to be leveled.

Abstract: A hydraulic system is provided with a prime mover connected to a first fixed displacement pump having a maximum flow A, a hydraulic loop connected to a system of valves and actuators, a second fixed displacement pump having a maximum flow B in fluid communication with the loop, an electric machine operable as one of a motor and a generator connected to the second pump and electrically coupled to a battery, and a controller connected to the prime mover and the electric machine. The hydraulic loop is in fluid communication with the first pump with a first check valve. The second pump is arranged in parallel with the first pump.

Abstract: A vehicle for lifting a load with respect to a support surface includes a load carrying member configured to carry the load, a frame, and a support assembly coupling the load carrying member and the frame. The support assembly is configured to move the load carrying member between stowed and deployed positions with respect to the flame. The vehicle further includes a plurality of motion devices that support the frame relative to the support surface, and the motion devices are configured to move the frame along the support surface. In addition, the vehicle includes a control system associated with the motion devices and configured to determine contact forces between the motion devices and the support surface. The control system is further configured to determine stability of the vehicle based on the contact forces.

Abstract: A hand lever fixture has a support body which can be attached to a handlebar, on which support body a hand lever and an over-center spring are pivotably mounted, said hand lever being effectively connected to a master cylinder and said over-center spring being effectively connected to the hand lever, which over-center spring, when the hand lever is in a position between a dead center position and an end position, generates a lever moment on the hand lever, said lever moment acting in the direction of the end position. The hand lever is split into a main lever which can be acted upon manually and an auxiliary lever pivotably mounted on the support body, at the end of which auxiliary lever the over-center spring is articulated while an auxiliary force resulting from the over-center spring lever moment can be transmitted to the master cylinder via its other end.

Abstract: An expansion reservoir is disclosed, which has a fluid chamber defined by a reservoir bottom and a flexible reservoir top movable relative to the reservoir bottom as a function of the reservoir filling level, wherein a hydraulic connection to a master cylinder is provided at the reservoir bottom while the reservoir top comprises a substantially liquid-tight but air-permeable connection to the atmosphere, in order to allow pressure compensation between an air volume left in the filled fluid chamber and the atmosphere. The hydraulic connection to the master cylinder comprises an extension protruding into the fluid chamber, which extension defines a predetermined volume V in the fluid chamber which is larger than the air volume left in the filled fluid chamber. In addition thereto, the reservoir top may take the form of a rolling lobe bellows, which comprises a plurality of wall portions substantially concentric at least in the undeformed state.

Abstract: A device for actuating a clutch, more particularly for motor vehicles, is disclosed, which has an operating lever pivoted on a bearing point, the operating lever being effectively connected to a master cylinder for the production of actuating pressure. The device also has a top dead center spring pivoted on a bearing point, which is articulated with the operating lever is in a position between dead center and an end position it exerts a force on the operating lever in the direction of this end position. According to the invention, both the bearing point for the top dead center spring and also the bearing point for the operating lever are provided on the master cylinder. An actuating device of simple design is thus created which can easily be mounted at the respective place of assembly, for example on the stationary pedal frame of a motor vehicle.
