A trailer includes a load-bearing carrier frame which is guided on an undercarriage and includes a lateral longitudinal member and two cross members protruding at right angles from either end thereof. Between these, a central member is secured to the longitudinal member, parallel to the cross members, and a loading opening is formed opposite said longitudinal member. A lifting device is arranged, for mutual height adjustment purposes, between the carrier frame and the undercarriage. A load-clasping gripping unit may be arranged on the central member and may be displaced in the transverse direction between the longitudinal member and the loading opening.

1. A trailer, comprising: a load-bearing carrier frame guided on an undercarriage, the carrier frame comprising a lateral longitudinal member and two cross members protruding at right angles from either end thereof, between which and parallel to the cross members, a central member is fastened to the longitudinal member, and a loading opening is formed opposite said longitudinal member,wherein a lifting device for a mutual height adjustment is located between the carrier frame and the undercarriage,wherein on the central member there is a load-clasping gripping unit located on the central member so that the gripping unit can be displaced in the transverse direction between the longitudinal member and the loading opening,wherein the gripping unit comprises at least one endless circulating chain from which drive fingers protrude,wherein the chain circulates in a housing which is displaced on the central member at a right angle to the longitudinal member, andwherein the housing, together with a guide rail that receives the housing, forms a carriage that can be telescopically retracted and extended on a carrier rail that is connected with the central member. 2. The trailer as claimed in claim 1, wherein the gripping unit is attached to a saddle that sits on the central member and is fastened to the central member. 3. The trailer as claimed in claim 1, wherein, on each side of the saddle, a carriage is displaced telescopically on a carrier rail. 4. The trailer as claimed in claim 1, wherein a roller train is attached to each of the two cross members. 5. The trailer as claimed in claim 1, wherein underneath the central member are the undercarriage, with two wheels mounted laterally on an axle, and the lifting device, which has at least one hydraulic cylinder supported between the axle and the central member. 6. The trailer as claimed in claim 5, wherein support rollers are attached to the cross members of the carrier frame. 7. The trailer as claimed in claim 1, wherein the central member is formed by two parallel lifting forks, which sit with their ends opposite the loading opening of the carrier frame seen in an overhead view on the upper end of the longitudinal member, wherein the carrier frame is C-shaped. 8. The trailer as claimed in claim 7, wherein the two cross members of the carrier frame support the lifting device on the undercarriage located underneath the carrier frame so that the carrier frame's height can be adjusted by means of hydraulic cylinders.
