Abstract: 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).

Abstract: 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.

Abstract: The invention relates to a crawler-tracked vehicle with variable track width, which can be used, in particular, as a construction vehicle and/or as a vehicle for agricultural purposes and, according to the features of the preamble of patent claim 1, comprises an undervehicle with a vehicle frame, on which is provided on each of the two sides a chassis with a chassis carrier in each case for at least one driving wheel and one deflecting wheel and for supporting wheels for the guidance of crawler tracks.

Abstract: 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.

Abstract: The invention relates to a tracked vehicle having smooth driving and idler wheels 6, 7, 8 and 9, respectively, which frictionally transmit the tractive force to tracks 3, 4, in particular to rubber tracks, and which are mounted by means of a frame 3 which carries at least one driving engine 11.

Abstract: 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).

Abstract: The invention relates to a skid track having equipment for a construction vehicle and, in particular, a vehicle (skid track) having a bucket 2 serving simultaneously for loading, said vehicle comprising a drive motor and a chassis 3 with a vehicle frame 4. On the vehicle frame 4, in each case running gear 5 with a driveable chain 6 is arranged at the side. For the chains 6, in each case a front guide and deflection wheel 7 at the bottom and a rear guide and deflection wheel 8 and also a third guide and deflection wheel 9 arranged at a higher level are provided. On both sides of the vehicle, in each case at least one of the two deflection wheels arranged at the bottom and serving simultaneously as guide and deflection wheels 7 and 8 has a sprocket 10, which engages in the chain 6 and can be connected to the drive motor.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a construction vehicle with a working appliance, in particular with a blade, which is mounted on a vehicle frame such that it can pivot in the vertical direction about an axis and is mounted such that it can pivot about a second axis substantially perpendicular thereto, for which purpose at least one hydraulic device is provided.

Abstract: 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.

Abstract: The invention relates to a vehicle which can be used in particular as an agricultural vehicle and/or for construction purposes and comprises at least one vehicle frame, a drive and an undercarriage in each case.

Abstract: The pipe-laying vehicle 1 possesses a lower vehicle body 2 with a driver's cab and a jib 10 which is supported on the lower vehicle body 2 and can be raised and lowered about a horizontal axis of inclination 11. In addition, the jib 10 can be swivelled about a vertical pivot axis by means of 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 about an adjustment axis 32 relative to the jib 10. This adjustment axis 28 extends in the longitudinal direction of the jib 10. By means of a mechanically or hydraulically actuated locking device, the pivot position of the sheave head 31 relative to the jib 10 can also be locked. As a result of the swivel capability both of the jib 10 and of the sheave head 31, the pipe laying work can be performed more simply and quickly.
