Patent number: 7373999Abstract: A crawler-tracked vehicle with a variable track width can be used as a construction vehicle and/or as a vehicle for agricultural purposes. The vehicle includes an undervehicle with a vehicle frame, on which is provided on each of the two sides a chassis with a chassis carrier respectively for carrying at least one driving wheel and one deflecting wheel and supporting wheels for the guidance of crawler tracks. At least one of the two chassis carriers (10, 11) can be fastened releasably to the vehicle frame (7) at a different distance transversely to the undervehicle (6) with carrying elements (24, 25) arranged laterally at the front and rear and with receiving and supporting elements (26, 27) and with holding and releasing elements (28).Type: GrantFiled: April 14, 2004Date of Patent: May 20, 2008Assignee: macmoter S.p.A.Inventor: Alois Johann Haringer

Patent number: 7086490Abstract: A tracked vehicle has smooth driving and idler wheels (6, 7, 8, 9), which frictionally transmit the tractive force to tracks (3, 4), e.g. rubber tracks, and which are mounted on a frame (3) of the vehicle which carries at least one driving engine (11). To avoid the slipping of the tracks on the driving and idler wheels, both the two front idler wheels (6, 7) and the two rear idler wheels (8, 9) are respectively driven. The front wheels are hydraulically driven, while the rear wheels may be hydraulically or mechanically driven.Type: GrantFiled: May 7, 2003Date of Patent: August 8, 2006Assignee: macmoter S.p.A.Inventor: Alois Johann Haringer

Patent number: 6719066Abstract: A construction vehicle has a working appliance such as a blade, which is mounted on a vehicle frame such that it can pivot in the vertical direction about a first axis and it can pivot about a second axis substantially perpendicular thereto, for which purpose at least one hydraulic device is provided. The position of the axis about which the working appliance can pivot can be varied in relation to the vehicle frame.Type: GrantFiled: March 26, 2002Date of Patent: April 13, 2004Assignee: macmoter S.p.A.Inventor: Alois Johann Haringer

Patent number: 6640915Abstract: A vehicle, which can be used in particular as an agricultural vehicle and/or for construction purposes, has a vehicle frame, a drive and an undercarriage. The undercarriage (4, 4a) includes on both sides wheels (12, 13) having tires, and/or chain wheels (70a, 71a) having crawler tracks/chains (72a), which are arranged one behind another in the running direction and as wheel groups (11, 11a), and also can be steered in each case as a wheel group (11, 11a) about a vertical Z-axis (21), and can be pivoted about a transverse Y-axis (19) arranged transversely with respect to the longitudinal X-axis (20) of the vehicle (1, 1a).Type: GrantFiled: June 27, 2001Date of Patent: November 4, 2003Assignee: macmoter S.p.A.Inventor: Alois Johann Haringer

Patent number: 6540095Abstract: The pipe-laying vehicle 1 includes a lower vehicle body 2, a driver's cab, and a jib 10 which is supported on the lower vehicle body 2, can be raised and lowered about a horizontal axis 11, and can be swivelled about a vertical pivot axis by a live ring. On the outer end of the jib 10, a sheave head 31 is provided with a deflection pulley 26 and a sheave 28, and can be swivelled as a whole relative to the jib 10 about an adjustment axis 32 that extends in the longitudinal direction of the jib 10. A mechanically or hydraulically actuated locking device selectively locks the pivot position of the sheave head 31 relative to the jib 10. As a result of the swivel capability of the jib 10 and of the sheave head 31, the pipe laying work can be performed more simply and quickly.Type: GrantFiled: January 16, 2001Date of Patent: April 1, 2003Assignee: macmoter S.p.A.Inventor: Alois Johann Haringer

Patent number: 6513404Abstract: A device for controlling the driving movements of a tracked vehicle includes a control lever 2 which can pivot about at least one pin 3, and a magnet arrangement by which any manually established position of the control lever 2 can be magnetically fixed. The strength of the magnetic fixing force is selected so that the control lever can be manually moved to a new position while overcoming the magnetic fixing force, and then the control lever is again magnetically held at the new position.Type: GrantFiled: November 2, 2000Date of Patent: February 4, 2003Assignee: macmoter S.p.A.Inventor: Alois Johann Haringer

Patent number: 6394204Abstract: A crawler or tracked vehicle has a running gear with separately operable tracks, and a vehicle body pivotably connected to the running gear about a substantially horizontal pivot axis that allows the running gear to pivot relative to the vehicle body. The two tracks can pivot independently of each other and independently of the vehicle body. At least one spring arrangement preferably including a spring and a shock absorber is arranged on each side of the body, and is respectively connected between the running gear and the vehicle body. The spring may be vertically or horizontally oriented.Type: GrantFiled: December 15, 1999Date of Patent: May 28, 2002Assignee: macmoter S.p.A.Inventor: Alois Johann Haringer

Patent number: 4693662Abstract: A compact excavator has a superstructure, a swinging or swivelling mechanism connecting said superstructure with a chassis for swinging said superstructure relative to said chassis about a vertical axis, and a boom on said superstructure. The boom is linked to the superstructure directly by a parallel guide having a parallelogram link (14 or 14') and an intermediate member (12). The parallel guide is able to swing about a vertical axis (13', 13") secured to the superstructure (3). The intermediate member (12) has a fixed length and the parallelogram link (14, 14') may have a fixed length link or a hydraulic actuator piston cylinder having a variable length. Such a construction simplifies additional movements required of the driver for operating the excavator.Type: GrantFiled: September 25, 1985Date of Patent: September 15, 1987Assignee: Macmoter S.p.AInventor: Luis Haringer
