    摘要： A boom (H) for a vehicle (A) which carries a working implement (K) to enable operations to be carried out such as excavation or loading, comprises first (11) and second (10) parts, the first part (11) carrying the working implement (K) and the second part (14) being mounted on a body (B) of the vehicle, the first and second parts being connected together for relative pivotal movement about a generally horizontal axis (A1), a fluid operated actuating means (18) acting between the first (11) and a second (10) boom parts to effect relative pivotal movement at least in one sense of rotation, characterized in that the fluid operated actuating means (18) comprises two relatively movable members (20, 23) which operate in tension, one member (20) being pivotally secured to one of the boom parts (14) and the other member (23) being connected via a flexible linkage (24) to the other boom part (11) to enable the two boom parts to be relatively pivoted to include a smaller angle between them than would be possible with a rigid linkage with an actuating means (18) operating in tension.

    摘要： A materials handling vehicle having two pairs of ground wheels movable to effect steering of the vehicle, the wheels of each pair being mounted at opposite sides of the vehicle chassis, at least one pair of wheels being lockable in a position so that steering is effected solely by the other pair of wheels wherein sensor means are provided associated with each of the two pairs of wheels to provide an electrical signal to a control means when the respective wheels are in an aligned position in which their axes of rotation are perpendicular to a longitudinal axis of the vehicle, the control means including a selector means comprising electrical switch means to enable an operator to select simple steering mode in which only one of the pairs of wheels are movable to effect steering, or a compound steering mode in which both of the pairs of wheels are movable to effect steering, the control means further comprising means to maintain the selected steering mode until an alternative steering mode is selected by operation of the selector means and the control means receives a signal from at least one of the sensor means associated with one of the pairs of wheels.

    摘要： A method of operating a boom (10) which comprises an elongate member (11) mounted on a base (12) for pivotal movement about a first axis (13) transverse to the axis of the elongate member (11), first fluid operated power means (20) mounted between the base (12) and the elongate member (11) to control raising and lowering of the member (11) about the first axis (13), an implement (15) mounted at one end of the member (11) for pivotal movement about a second axis (18) transverse to the axis of the elongate member (11). second fluid operated power means (24) comprising a double acting ram having a cylinder (25) and plunger (26) slidable therein, mounted between the implement (15) and the member (11) to control movement of the implement (15) about the second axis (18), means to feed fluid under pressure to and from the first fluid operated power means (20) along first feed lines (27a, 27b) via a first operating valve (28), means to feed fluid under pressure to and from the second fluid operated power means (24) along second feed lines (21a, 21b) via a second operating valve (32), a displacement means (35) comprising a further double acting fluid operated ram connected between the member (11) and the base (12) to sense movement of the member (11) about the first axis (13), fluid lines (39a, 39b) from the displacement means (35) to the second fluid operated power means (24) to transmit a signal to the second fluid operated power means (24) to cause the second fluid operated power means (24) to operate to maintain the orientation of the implement (15) relative to the base (12) as the implement (15) is raised and lowered on the member (11), the method including the steps of providing fluid under pressure to the displacement means (35) during raising of said one end of the elongate member (11), whereby said displacement means (35) contributes to the raising of said one end of the member (11).

    摘要： A controller for use with a working machine comprising a machine body and a load handling apparatus coupled to the machine body and moveable by a lift actuator with respect to the machine body, wherein the controller is configured to receive: a signal representative of a lateral inclination angle of the machine body with respect to a lateral reference orientation; and a signal representative of a stability of the working machine. The controller is further configured to determine a permissible movement range of the load handling apparatus with respect to the machine body or a longitudinal reference orientation and issue a signal for use by an element of the working machine including the lift actuator, which in response to the signal issued by the controller is configured to restrict or prevent movement of the load handling apparatus outside of the permissible movement range relative to the machine body or longitudinal reference orientation, the permissible movement range being dependent on the signal representative of a lateral inclination angle of the machine body with respect to a lateral reference orientation and the signal representative of the stability of the machine. The permissible movement range is obtained by determining a stability envelope for the working machine and a location of the working machine's centre of gravity. The permissible movement range is chosen such that the working machine's centre of gravity remains in the stability envelope across the whole of the permissible movement range.
