Abstract: A forklift truck with a forward-tilting cab and a method for reducing the container-loading height of the forklift truck, include a cab and a frame, the cab being connected to the frame so as to be able to tilt forward; and also including a locating mechanism, which is removably provided between the cab and frame when the cab is tilted forward to reduce the cab height, so as to locate the cab when the cab is tilted forward to a preset angle. When loading into a container, the cab of the forklift truck is tilted forward to a preset angle, so that the overall height of the forklift truck is reduced to a height suitable for loading in a container, and the locating mechanism is used to locate the cab, so that the cab is kept in a state in which it is tilted forward to a preset angle.

Abstract: An authorized electrical plug has a plug surface with first and second plug edges and left and right side plug edges. The plug surface has left and right prongs projecting outwardly from the plug surface. A recess has a depth formed in the plug surface. An authorized electrical receptacle has a receptacle surface with first and second receptacle edges, left and right side receptacle edges, and left and right slots extending inwardly. A projection has a height formed in the receptacle surface. Left and right slots receive the left and right prongs respectively with the recess receiving the projection when an authorized electrical receptacle receives an authorized electrical plug.

Abstract: A joystick controller comprises a housing (10) and a joystick (12) mounted for pivotal movement relative to the housing (10) by means of a ball (14) and socket joint (18,20). A yoke (18) resolves directional movement of the joystick (12) into a component direction. A sensor senses movement of the yoke (18) and generates an output indicative of movement of the joystick in the component direction. The socket (18,20) of the ball (14) and socket joint (18,20) is formed by the yoke (18).

Abstract: A joystick (1) having a yoke pivotally secured to an upper support (28) and a lever (16) pivotally secured to a lower support. The yoke has a latching portion that engages a cam roller (14) on the lever to push the lever downward. Supported on the lever is an armature (24) positioned in spaced relation to a solenoid (26). The solenoid is energized based on the movement of the yoke.

Abstract: A joystick controller comprises an operating shaft mounted for pivotal movement relative to a body. The operating shaft extends through an opening in the body. A bush is coupled to the operating shaft and biased into contact with a contact surface of the body so as to provide a force resisting movement of the operating shaft away from a null position. The contact surface has a form configured to provide a change in the resistive force that increases linearly with an increase in angle of displacement of the operating shaft away from the null position.

Abstract: A joystick controller has a lever mounted for pivotal movement relative to a housing, a seat member affixed to the housing, and a slider member biased towards the seat member. The seat member has a profiled surface that cooperates with a corresponding surface of the slider member. In one aspect, the profiled surface includes at least one lock position for engaging the slider member at a predetermined angle of pivotal displacement of the lever about a first axis. The slider member is shaped to allow pivotal movement of the lever about a second axis, without movement of the slider member, but to prevent movement of the lever about the first axis when engaged in the lock position.

Abstract: The apparatus is used in grind, polish or clean etc, the surfaces of an object such as a pipe. The apparatus comprises a rotary tool (1) having an axis of rotation, at least one wall and a chamber defined between the axis and the wall fore receipt of the object, and a conditioning member for contact with said surface of said object, the conditioning member (14) projecting into said cavity and being fixed to said wall so that it rotates therewith. The apparatus may comprise means for connection (8) to a rotation actuator and may be connected to a centrally located bore member (1) connected to a further plurality of conditioning members. Additionally, means to bias the conditioning members towards the surface to be conditioned may be included comprising compressed air and/or the magnetic attraction of a magnetic material embedded in the main body of the apparatus to the surface to be conditioned.
