Abstract

Pipe-laying equipment for a hire machine has a pipe- holder device 18 with a bearing arm 20 for introduction into the pipe 22, a support 21 for cooperation with the outside of the pipe, and a connection element 19 which carries the bearing arm and the support and connects them to the stand 1, the bearing arm being rigidly connected to the connection element. According to the invention, the support 21 is also rigidly connected to the connection element 19, which in turn is securely connected to the stand. The free end of the bearing arm forms the centre of tilting for the pipe, so that the latter tilts to a limited extent about the centre of tilting, while the support 21 forms a stay for the end section 24 of the pipe and maintains the pipe in freely releasable engagement with the free end of the bearing arm. The distance between the bearing arm and the support and the length of the bearing arm are selected such that the pipe slopes at a slight acute angle alpha relative to the bearing arm. The pipe-holder device is therefore completely free from links and hinges. <IMAGE>
