Abstract: In the use of a tractor to maneuver an airplane on its nose landing gear, which tractor includes a chassis (10); having a rear access (32) which receives said nose wheels and having two telescoping bars (38) the length of which can be adjusted by means of first hydraulic cylinders (40) and to the rear ends of which (38.2.1) pivotable pulling arms (54) are hingedly connected for engagement behind the nose wheels; and having a support surface (30.3) for the raising of the nose landing gear, which is performed by means of second hydraulic cylinders (44), in order to cause less wear on the nose wheels during loading and raising and to prevent damage to the tractor and/or nose landing gear in the attempt to pull said nose landing gear into the recess by means of the pulling arms, it is suggested:(a) to form the chassis in two parts and to hingedly connect its front portion (10.1) with its rear portion (10.

Abstract: A loader, especially a bucket loader for underground use in mining operations, comprising a rear car carrying the propulsion unit including the hydraulic pump and the driver's station, and a front car coupled to the rear car by a hinge joint and carrying the bucket and the hydraulic system for operating same. The rear car is formed by a chassis stiffly joined to the rear axle, which chassis has a stiff bulkhead serving for the mounting of the motor and transmission assembly. The motor and transmission assembly is disposed on a secondary frame which has also a bulkhead that can be fastened to the bulkhead of the chassis, from which on both sides of the motor and transmission assembly longitudinal girders project, between which the motor and transmission group is mounted.

Abstract: A motor-driven vehicle for selective use for transporting material and for transporting personnel, especially for use in underground mining operations, with a loading platform for the material to be transported. Below the loading platform parallel to the two longitudinal boundaries of the vehicle one bench or seat row each for transporting persons is provided. The area of the loading platform covering the respective bench or seat row is constructed as a loading platform part pivotable upwardly about an axis extending in the longitudinal direction of the vehicle and adapted to be locked in the upwardly pivoted position.
