A boom lift machine (10) is provided which includes: a body (12); a boom (14) defining a longitudinal axis (A-A);a mounting arrangement (50) mounting the boom to the body; and a lifting unit (54) extending between the boom and the mounting arrangement. The boom is pivotably connected to the mounting arrangement at or proximate a first end (16) of the boom. The mounting arrangement is configured such that in response to actuation of the lifting unit, the boom is pivoted to raise or lower a second end (20) thereof, and the boom is translated relative to the body. The boom lift machine also includes a counterweight mass configured to counterbalance a tipping moment of the boom lift machine. The counterweight mass is configured to translate with the boom.

A working machine comprising:an operator station; andan operator seat located at the operator station;the operator station comprising controls for moving the working machine via the ground engaging propulsion structure and working arm controls for controlling movement of the first working arm relative to the body;the operator seat being moveable between a first position and a second position;a display being positioned at the operator station and within the operator's field of vision when seated on the seat in the second positiona further display being positioned at the operator station and within the operator's field of vision when seated on the seat in the first position;the working machine being configured such that at least when the seat is positioned in the first position at least one of the following is displayed on the further display: a drive state of a transmission of the working machine, a steer mode of the working machine, a wheel drive state of a ground engaging propulsion structure (2WD/4WD), a steer position (wheel alignment state) of a ground engaging propulsion structure;the working machine being further configured such that at least when the seat is positioned in the second position at least one of the following is displayed on the display: a drive state of a transmission of the working machine, a steer mode of the working machine, a wheel drive state of a ground engaging propulsion structure (2WD/4WD), a steer position (wheel alignment state) of a ground engaging propulsion structure.

A casing (12) for receiving a loose insulating material, the casing comprising:an inner shell (22) of flexible sheet material;an outer shell (24) of flexible sheet material; anda baffle arrangement (26) located between and connecting the inner and outer shells and comprising adjacent first and second elongate baffle members (28,30) of flexible sheet material laterally spaced along the inner and outer shells, the first and second baffle members, inner shell and outer shell defining one or more chamber for receiving the insulating material,wherein the first baffle member and the second baffle member are connected to the outer shell along a respective baffle outer edge at an outer connection region (48) and to the inner shell along a respective baffle inner edge at an opposing inner connection region (40),the opposing inner and outer connection regions of the first baffle member being non-linear and following an inverse path from one another.

Disclosed is an excavator comprising: a ground engaging structure comprising a pair of track assemblies for propelling and steering the excavator; a rotatable superstructure mounted to the ground engaging structure; a working arm mounted to the rotatable superstructure, the working arm comprising one or more hydraulic actuators arranged to operate the working arm; a hydraulic pump in hydraulic flow communication with the one or more tracks and/or the one or more hydraulic actuators; a hydraulic tank connected to the hydraulic pump; at least one electric motor configured to drive the hydraulic pump to provide a flow of hydraulic fluid to propel the one or more track assemblies and/or operate the hydraulic actuators; at least one battery for providing electrical power to the hydraulic pump; and, at least one electrically operated fan configured to provide a flow of cooling air onto the hydraulic tank to cool the hydraulic fluid therein.

A hydrogen fuel internal combustion engine comprising a cylinder head and one or more cylinder assemblies. The or each cylinder assembly comprises: a combustion chamber at least partially defined by a roof of the cylinder head; and a spark plug extending through the roof, the spark plug comprising a first electrode separated from a second electrode via a gap. At least one of the first and second electrodes protrudes from the roof such that the gap is within the combustion chamber. Each cylinder assembly comprises a barrier on or adjacent the spark plug configured to inhibit a liquid flowing on the roof reaching the gap.

A working machine, comprising: a ground-engaging propulsion arrangement; a body mounted to the ground-engaging propulsion arrangement, the body comprising an operator station; a plurality of assignable controllable elements; a configurable foot pedal in the operator station for controlling a selected one of the assignable controllable elements; an input device arrangement; and a controller in communication with the configurable foot pedal and the input device arrangement. The controller is configured to: receive a selection input from the input device arrangement; assign any one of the assignable controllable elements for control by the configurable foot pedal based on the selection input received from the input device arrangement; receive a control input from the configurable foot pedal; and control the assigned controllable element based on the control input received from the configurable foot pedal.

Disclosed is a reduced tail swing excavator (100b) comprising: an undercarriage (118b) comprising left (102b) and right (104b) ground engaging structures; a superstructure (106b) rotatably mounted to the undercarriage; a working arm (108b) pivotally connected to the superstructure and comprising a plurality of actuators (62b, 64b, 66b) to enable manipulation of the working arm by an operator; an operator cab (107b) mounted on the superstructure comprising a seat and operator controls for controlling the undercarriage, the working arm actuators and the rotation of the superstructure relative to the undercarriage; an engine (109b) mounted aft of the operator cab on a plurality of engine mounts (14); and, a counterweight (111b) mounted aft of the engine, the counterweight comprising left and right mounts (24), wherein the superstructure comprises a transverse structural member (18) which extends laterally across the excavator, the transverse structural member comprising counterweight seat (16) on which the counterweight mounts are located and at least one of the engine mounting point proximate to one of the counterweight seat; and, wherein the transverse structural member comprises a shim access aperture (34) located between the engine mounting point and the counterweight seat to allow shimming of the counterweight without removal of the counterweight from the superstructure.

Disclosed is a method for controlling the braking effort of a tractor unit relative to the braking effort of a trailer being towed by the tractor unit, the method comprising: activating an enhanced braking mode in the tractor unit; receiving a braking command from an operator input device whilst in the enhanced braking mode; increasing a tractor unit speed demand on the tractor unit whilst receiving the braking command; applying the brakes to the trailer and tractor unit, wherein the braking effort applied to the tractor unit is reduced relative to the trailer due to the increased speed demand.
