## Abstract

A steerable carriage for transferring wheeled vehicles includes a device for engaging in the carriage with a vehicle in a propulsion force transmitting manner and for elevating at least one wheel of the vehicle from a ground level, with the carriage transmitting a propulsion force to the vehicle through the engaging device and through the at least one elevated wheel of the vehicle, at least one support member on the engaging device arranged to be respectively movable to cause the wheel and the support member to assume a relative position in which at least a part of the wheel is located on the support member and is supported by the support member, at least one actuating a member on the engaging device, a chassis having at least one steerable wheel in its forward part, and legs on the chassis extending between the forward part and the engaging device, wherein said legs have an adjustable length to permit adjustment of a distance between the forward part of the chassis and the engaging device.

## Claims

### Claim 1

A steerable carriage for transferring wheeled vehicles, comprising:
means for engaging the carriage with a vehicle in a propulsion force transmitting manner, and for elevating at least one wheel of the vehicle from a ground level, said carriage being arranged to transmit a propulsion force to the vehicle through said engaging means and through said at least one elevated wheel of the vehicle;
at least one support member on said engaging means arranged to be respectively movable to cause the wheel and the support member to assume a relative position in which at least a part of the wheel is located on the support member and is supported by the support member;
at least one actuating member on said engaging means;
a chassis having at least one steerable wheel in a forward part thereof; and
legs on said chassis extending between the forward part and said engaging means, wherein said legs have an adjustable length to permit adjustment of a distance between the forward part of the chassis and said engaging means.

### Claim 2 (depends on 1)

The carriage of claim 1, wherein said legs are of a telescoping design.

### Claim 3 (depends on 2)

The carriage of claim 2, wherein said legs, comprise:
two projectable telescope parts; and
two telescope parts arranged to be in engagement with said projectable parts and secured to the forward part of the chassis.

### Claim 4 (depends on 3)

The carriage of claim 3, wherein a power member of a type variable in length is arranged to act between the telescope parts of the legs.
