Patent number: 10953739Abstract: A work vehicle (1) comprising a forward part (3) and a rearward part (7) pivotally coupled about a main vertical pivot axis (10) for steering thereof. A power take-off shaft (29) is located adjacent a forward end (31) of the forward part (3) and is mechanically driven from a main output drive shaft (15) of an engine (14) located in the rearward part (7). A step-up gearbox (20) steps up the speed from the main output drive shaft (15) onto first and second output shafts (23, 24) for driving first and second hydraulic pumps (27, 28) which provide hydraulic supplies for motive power and for operating attachments attached to the forward end (31) of the forward part (3). A step-down gearbox (30) receives drive directly from the main output drive shaft (15) of the engine (14) and produces a stepped-down drive on an output shaft (33) of the step-down gearbox (30) with a gear ratio of 2:1.Type: GrantFiled: November 3, 2016Date of Patent: March 23, 2021Assignee: MULTIHOG R&D LIMITEDInventors: James Mcadam, Gerard Mchugh, Anthony Duff, Dallan Mchugh, Daniel Mcelchar, Samuel Hampshire

Patent number: 10939602Abstract: A work vehicle (1) comprises a coupling apparatus (18) for coupling an attachment to the forward end (8) of the work vehicle (1). The coupling apparatus (18) comprises a three point linkage mechanism having a pair of lower coupling elements (19) and an upper coupling element (25). A first carrier element (22) is pivotally coupled to a forward chassis part (14) of the work vehicle (1) by a pair of main transverse pivot shafts (35) which define a main transverse pivot axis (33). A second carrier element (23) carries the lower coupling elements (19) and is pivotally coupled to the forward chassis part (14) about the main transverse pivot axis (33) and about a main longitudinal pivot axis (45).Type: GrantFiled: December 7, 2016Date of Patent: March 9, 2021Assignee: MULTIHOG R&D LIMITEDInventors: James McAdam, Gerard McHugh, Anthony Duff, Dallan McHugh, Daniel McElchar, Samuel Hampshire

Publication number: 20190314869Abstract: Apparatus on a driver's cab roof mounts a hose terminating in a nozzle of a vacuum system. The apparatus includes a proximal carrier arm pivotally mounted on the cab roof about a vertically extending main pivot axis by a slewing mechanism. A distal carrier arm is pivotally coupled to the proximal carrier arm about a transversely extending horizontal first pivot axis. A first ram pivots the distal carrier arm upwardly and downwardly relative to the proximal carrier arm. The distal carrier arm is extendable between its proximal end and its distal end by a second ram. By pivoting the proximal carrier arm by the slewing mechanism, the nozzle is urged from one side of the vehicle to the other. By pivoting the distal carrier arm upwardly relative to the proximal carrier arm, and simultaneously extending the distal carrier arm, the reach of the nozzle is increased.Type: ApplicationFiled: November 27, 2017Publication date: October 17, 2019Applicant: MULTIHOG R&D LIMITEDInventors: James MCADAM, Samuel HAMPSHIRE, Daniel MCELCHAR, Gerard MCHUGH

Publication number: 20180291577Abstract: An attachment (60) for a wheeled work vehicle (2) for clearing snow comprises a support housing (3) which rotatably carries an elongated cylindrical brush (5) and a plough blade (4), with the plough blade (4) and the brush (5) alternately operable between a lower operative state and an upper inoperative state. End elements (62) are pivotally coupled about vertical pivot axes adjacent respective opposite ends (15,16) of the plough blade (4). The end elements (62) are pivotal about a main vertical pivot axis (64) between a plurality of forward and rearward states through respective outward states. A coupling mechanism (7) couples the attachment (1) to the wheeled work vehicle (2) so that the support housing (3) is slewable between a transverse state and respective maximum offset states.Type: ApplicationFiled: May 16, 2016Publication date: October 11, 2018Applicant: MULTIHOG R&D LIMITEDInventors: Sean CONNOLLY, Anthony HAVERN, James MCADAM, Gerard MCHUGH

Patent number: 9896811Abstract: An apparatus for removing material from the ground is disclosed, with a path-clearing blade, a vehicle mounting, a body supporting the blade, and a jointed connection between the vehicle mounting and the body permitting the axis of the blade and body to rotate within a plane parallel to the ground. The jointed connection has first and second pivot arm each pivotally connected about a proximal axis of rotation relative to the vehicle mounting and pivotally connected about a distal axis of rotation relative to the body. As the body's axis rotates in the clockwise sense, the first and second arms each pivot counterclockwise about their respective proximal axes of rotation, and vice versa. The arms are preferably disposed above the body and the distal axes of rotation are mounted forwardly of the rear edge of a horizontal rotating brush mounted in the body behind the blade.Type: GrantFiled: March 16, 2012Date of Patent: February 20, 2018Assignee: MULTIHOG R & D LIMITEDInventors: Jim McAdam, Gerry McHugh
