Compressed air hoses and hydraulic hoses (33, 34) for actuating various devices on a trailer are automatically coupled together since the tractor (11) and the trailer (13) have two corresponding valve blocks (30, 25) with corresponding valves and the valve block (30) of the tractor is moved against the valve block (25) of the trailer. The valve block (25) of the trailer is turnable and it has the same axis of turning as the trailer on the tractor. Means (50, 51) arranged in connection with the valve block (30) of the tractor is arranged to turn the valve block (25) of the trailer right and to guide the valve blocks before their valves (55, 56) are coupled. |
