A seat system for a vehicle for lifting and moving loads has a seat rotation mechanism which is operable in response to control signals received from a control system, to rotate the operator seat relative to the vehicle chassis. The control system receives an input from a directional control used by the operator to steer all of the vehicle's wheels together in a common direction so that the vehicle is driven over the ground in a certain direction without rotation of the chassis relative to the ground. By rotating the seat towards the direction of travel, the operator's visibility is improved.

A load lifting vehicle comprising two opposed rails connected by a base, a carriage configured to move along the rails, a mast cross member configured to move along the rails, a first hydraulic cylinder and second hydraulic cylinders connected to the mast cross member, wherein the first cylinder is configured to move the carriage with respect to the mast cross member and the second cylinders are configured to move the mast cross member, the first cylinder and carriage with respect to the base.
A lift truck (10) has a pair of wheel assemblies (21) each of which is rotatable about a pivot point (24) relative to the chassis (12) of the truck through at least 90 degrees between a forward mode and a sideward mode. The wheel (18,20) of each assembly is laterally offset from the assembly's pivot point (24), causing the wheel to describe an arcuate path over the ground as it transitions between the forward and sideward modes. During the transition, an actuator acts on each wheel assembly (21) to pivot the assembly about the pivot point (24), while drive is applied to the wheel to positively drive the wheel along the arcuate patch at a speed that matches the pivotal rotation caused by the actuator. This positive drive imparted to the wheels (18,20) during the transition prevents the truck from rolling if it is located on a slope during the change in orientation of the wheel assemblies (21).

DIFFERENTIAL STEERING ARRANGEMENT FOR ELECTRICALLY DRIVEN LIFT TRUCKS
A lift truck has a pair of driven wheels at one end, each with an independently controllable electrical motor, and at least one steerable wheel at the other end. A linear sensor measures the distance between a fixed point on the lift truck chassis and a moveable point associated with the steering gear of the steerable wheel. The linear sensor output is provided to a motor controller which derives from the measured distance and the geometry of the lift truck a lateral distance to a common centre of turning circles where each turning circle is associated with a wheel of the truck and each wheel is tangential to its turning circle. The controller calculates a required drive speed for the electric motor of each driven wheel according to the distance of that wheel from the calculated common centre of turning circles, and outputs a respective independent motor control signal effective to cause the drive motors to drive the driven wheels at speeds which avoid slippage or skidding and thereby provide an electronic differential to the driven wheels.

A tractor unit is disclosed for transporting an elongated load such as a wind turbine blade or wind turbine tower segment. The tractor unit body is supported, driven and steered by a wheel set comprising at least three ground-engaging wheels. At least two of the wheels are steerable and can transform between an aligned mode of operation and a carousel mode of operation. In the aligned mode, the wheels are aligned with one another in a neutral steering position, and steerable to vary the direction of steering. In the carousel mode, the wheels of the wheel set are oriented with their axes of rotation intersecting at a substantially common vertical axis located within the lateral extent of the tractor unit body, so that when the wheels are driven the tractor unit spins about this common vertical axis. A load engagement mechanism is mounted pivotally on the tractor unit body about the common vertical axis. This allows the load engagement mechanism to be counter-rotated in an equal and opposite amount to the angular rotation of the tractor unit body in carousel mode, keeping the load in fixed position relative to the ground as the tractor unit spins.

A system for use in the ventilation of a patient, particularly for a patient using a breathing circuit that is connected along with one or more other breathing circuits to a shared ventilator. The system employs a flow control valve on an inspire air line of an individual breathing circuit for that patient, and measures the tidal volume and pressure in the breathing circuit. A controller is provided with a user interface allowing a desired target volumetric measurement to be input. In response, a control signal is calculated and output to the valve causing the air supply on the inspire line to be adjusted until the measured tidal volume matches the desired volume within a given tolerance. In this way, patient safety is improved for a shared ventilator, by tailoring the ventilation on an individual breathing circuit using a single input value.

An articulated vehicle [10] has a first body section [12], a second body section [14], and an elongate projection [22] projecting from the first body section [12] towards the second body section [14]. A pair of steering cylinders [36, 34] are mounted such that they are partially or wholly disposed in or on the elongate projection [22], and are disposed one above the other so they overlap vertically, thereby narrowing the projection at the end nearer the first body section [12] and allowing the second body section [14] to be rotated closer to the centre line. A rotatable shaft [40] of the second body section [14] is mounted towards the far end of the elongate projection [22] and is steered by a pair of linkages such as chains [42, 44], each of which is connected to the shaft [40] and to a respective one of the steering cylinders [36, 34]. The chains [42, 44] wrap around the shaft [40] with a circumferential overlap, though they are spaced vertically. This circumferential overlap allows steering angles significantly in excess of 180° to be achieved.
A pedestrian truck (50) steered with a tiller (56) is operable in a first mode where a controllable front wheel (64) is aligned generally parallel with a front-rear centre line of the truck, or a second mode where the wheel is generally perpendicular to the front-rear centre line. A steering controller can operate in either a normal steering mode to steer the rear steerable wheel (52) in the same sense (clockwise or anticlockwise) as the tiller is rotated and in an alternate steering mode to steer the rear steerable wheel in the opposite sense to the rotation of the tiller. A steering mode selector is provided which automatically engages the alternate steering mode when the truck is in the second mode of operation and either (i) the tiller is positioned on the same side of the centre line as the controllable front wheel and the drive direction is such that the tiller leads the truck (figures 12-14), or (ii) the tiller is positioned on the same side of the centre line as the castor front wheel (58) and the drive direction is such that the tiller trails the truck (figures 4, 5).
A load-carrying truck has a fork lift mechanism mounted on a chassis, a pair of front wheels (24, 26) and a single rear wheel (30). At least one front wheel (26) and the rear wheel (30) are driven wheels whose speed is varied relative to one another differently depending on whether the truck is being driven in a forward reverse mode with the front wheels (24, 26) aligned generally parallel to the front-rear axis of the chassis and with steering controlled by steering the rear wheel (30), or a sideways mode with the rear wheel (30) aligned generally perpendicular to the front-rear axis of the chassis and with steering controlled by steering the at least one of the front wheels (26). When the truck is operated in forward/reverse mode and is steered towards the side on which the driven front wheel (26) is located, the relative speed (26) of that wheel is decreased progressively and comes to a stop when the axis of rotation of the rear wheel (30) intersects the front wheel position, and is driven in reverse at increasing speeds as the axis of the rear wheel (30) passes that point of intersection with further increasing steering angle. In the sideways mode of operation when the truck is steered in the direction towards the rear end of the chassis, the relative speed of the rear wheel (30) is decreased progressively and comes to a stop when the axis of rotation of the steered front wheel (26) intersects the rear wheel position, and the rear wheel (30) is driven in reverse at increasing speeds as the axis of the steered front wheel (26) passes said point of intersection with further increasing steering angle.

A motorised truck with tiller such as a pallet carrier or forklift truck has a tiller- controlled steerable wheel 14 which is steered by a motor having an associated steering motor controller. The steering motor controller in a normal mode of operation detects movement of the tiller as it is rotated relative to the chassis to steer the truck, and outputs control signals to cause the steering motor to steer the wheel such that it follows the tiller angle with a fixed, predetermined offset (which may be zero or non-zero). In a realignment mode of operation, the controller can change the predetermined angular offset, and the controller can preferably align the wheel with the tiller or with an axis of the chassis. The truck can be manoeuvred more easily into and out of tight spaces with the operator and tiller offset to the side of the truck. The tiller can also be offset manually from the wheel by decoupling the tiller and wheel, and thereby changing the predetermined offset for subsequent operation.
