Patent
CA 2330076
The pipe-laying vehicle 1 possesses a lower vehicle body 2 with a driver's cab and a jib 10 which is supported on the lower vehicle body 2 and can be raised and lowered about a horizontal axis of inclination 11. In addition, the jib 10 can be swivelled about a vertical pivot axis by means of a live ring. On the outer end of the jib 10, a sheave head 31 is provided with a deflection pulley 26 and a sheave 28, and can be swivelled as a whole about an adjustment axis 32 relative to the jib 10. This adjustment axis 28 extends in the longitudinal direction of the jib 10. By means of a mechanically or hydraulically actuated locking device, the pivot position of the sheave head 31 relative to the jib 10 can also be locked. As a result of the swivel capability both of the jib 10 and of the sheave head 31, the pipe laying work can be performed more simply and quickly.
