An object responsive control system for a work machine having a boom, an attachment pivotally coupled to the boom, an object sensor adapted for sensing the presence of an undesirable object located in a travel path of the work machine and delivering an object signal upon sensing the undesirable object. A controller adapted for receiving a boom position signal, an attachment position signal, and calculating an elevational position based on the boom position signal. The system activating an object response upon calculating an attachment elevation position above a predetermined threshold and receiving an object signal.

A device and a method for decelerating a vehicle having a front-loading device has a brake system and sensors for measuring the mass and the center of gravity of a load. An electronic evaluation and control unit evaluates the sensor data to determine a maximum brake deceleration in forward travel, in order to prevent the vehicle tilting about the front axle. At least one sensor of the brake system generates a sensor signal in an emergency braking situation for triggering an emergency braking operation, in which the delimitation or reduction of the effective brake pressure in the wheel brake cylinders of the front axle is canceled and, with the exception of an ABS control operation, the full brake pressure is introduced in a controlled manner by way of a primary brake valve into the wheel brake cylinders of the front axle.

A mobile lift device includes a body supported on a driven wheel and a lift supported by the body and configured for vertical movement relative to the body. The lift is configured to support a load. An electric drive motor is configured to cause rotation of the driven wheel and a drive motor brake is coupled to the motor. An electromechanical linear actuator is configured to raise and lower the lift and includes an electric actuator motor. A controller is configured to determine the weight of the load. In one embodiment, the controller determines the weight by determining a level of current required by the electric actuator motor. The controller controls at least one of the electric drive motor and the drive motor brake responsive to the weight of the load.

The present invention is related to a cooling device for a forklift brake system, which is capable of maintaining a predetermined level of heat-radiation performance by reducing heat when heat is generated in a service brake that is provided at a forklift driving shaft. A cooling device for a forklift brake system according to an exemplary embodiment of the present invention allows cooling oil to bypass a cooler when a pressure of the cooling oil is abnormally increased or there is a concern that a pressure of the cooling oil is increased, thereby preventing the cooler from being damaged.

Devices and methods to relieve lift chains from being maintained under constant, or nearly constant, tension are provided.

An axle housing supporting structure includes an axle housing, a brake housing, an axle bracket for supporting the axle housing and the brake housing, a connecting member inserted in the axle housing and the axle bracket to connect the axle housing and the axle bracket for preventing the axle housing from falling from the axle bracket, and at least one co-fastening bolt fastening the axle bracket, the brake housing, and the axle housing together.

A system is described for presenting information relating to lifting and moving a load object with a vehicle. Upon the lifting, a dimensioner determines a size and a shape of the load object, computes a corresponding spatial representation, and generates a corresponding video signal. During the moving, an imager observes a scene in front of the vehicle, relative to its forward motion direction, and generates a video signal corresponding to the observed scene. The imager has at least one element moveable vertically, relative to the lifting. A display renders a real time visual representation of the scene observed in front of the vehicle based on the corresponding video signal and superimposes a representation of the computed spatial representation of the load object.

Technologies are described for restraining systems. The systems may comprise a base, a stationary arm, a swing arm, a rod, first straps, and second straps. A bottom end of the stationary arm may be attached to a first end of the base. A bottom end of the swing arm may be attached at a second end of the base. The rod may be attached to top ends of the stationary arm and the swing arm. First straps may be attached to the stationary arm and configured to loop around and support an object. Second straps may be attached to the swing arm and configured to loop around and support the object. The rod may move and push the top of the swing arm away from the top of the stationary arm. A friction force between the first and second straps and the object may be effective to restrain the object.
