ABSTRACT:
A pipelaying appliance (1) is removably connected to the bucket (2) of an excavator with the aid of a gripping means (3) mounted on the bucket. The appliance includes two gripping arms (7, 8) of which one thrusts into the pipe (9) and the other is situated on the outside of the pipe. The gripping arms are movable to and from each other and are connected to the appliance so that the clamping force of the gripping arms on the pipe wall will be proportional to the weight of the pipe carried by the appliance.
