Abstract: Transport arrangements for cutting heads or the like have previously been configured as independent one or two-axle trailers upon which the implement could be deposited. The disadvantage is that thereby a self-supporting construction is required which entails high costs. In another known embodiment a two wheel trailer is attached to both the front and the rear end of the implement, which is costly and increases the length of the complete rig. The transport arrangement proposed consists of a draft tongue and a trailer, where the tongue is inserted into and secured to the implement and the trailer is attached underneath the implement. Transport arrangements of this type are used to transport agricultural implements.

Each trailer has a body consisting of a pair of upstanding, oppositely disposed sidewalls which are hinge mounted in a frame on the trailers and move from a vertical position forming the sides of a gondola body to a flat-bed condition wherein the sidewalls pivot upwardly into an over-lapped horizontal condition and form a flat-bed body with a top over the flat-bed.

Abstract: A self-unloading load hauling box for use on a towed carriage or carried by a powered mobile vehicle wherein the box is a rigid unit having a bottom wall with a floor plate and side walls and front end wall projecting up from the rigid bottom wall. An endless belt is looped around the bottom wall and runs on a driven roller at the rear end and an idler roller at the front end of the box. The endless belt is driven through an arc of selected length at spaced apart intervals to unload contents from the box. The jerky action from intermittently driving the belt has a tendency to cause a vibration, loosening the content in the box and thus results in a relatively even discharge during unloading. Between the upper run of the endless belt and the upper surface of the floor is a friction reducing pad which also absorbs shock loads tending to reduce damage to the belt and/or floor when loading heavy chunk material.

Abstract: For commercial and special vehicles, such as e.g. weapon transporters, mobile radar stations, mobile satellite control stations and mobile cranes, which must carry very considerable weight, very robust chassis are required.The inventive chassis (1) has a so-called box-frame construction. It comprises a lower and an upper carrier plate (2, 3), which are reinforced and joined by reinforcing elements (12) located between them. This construction leads to an enormous load bearing capacity and extremely high rigidity against twisting or torsion in the case of a reduced height of chassis (1). Unlike the case of conventional chassis constructions with an overall height of 30-40 cm, minimum heights of approximately 10 cm are possible here. Through covering the outer faces of the chassis with vertical cover plates, an additional reinforcement is obtained.These measures permit a configuration which, even when using large wheels, makes it possible to mount the chassis at a very low level.
