Hydraulic line-up skid
This skid is designed for use on steep slopes where pipe-laying tractors cannot work and when the cost of installation of a cableway is not justified. The skid runs on solid rubber wheels and has been built to run inside the trench, supported and driven by a winch located ahead of it. The pipe is placed on the two rubber coated saddles and fastened to them with straps, then the sled is lowered along the slope inside the trench. When it arrives in position, a generator starts the motor on the skid and with its hydraulic system the pipe can be raised or lowered crosswise to align the pipe for clamping.

Hydraulic internal clamp for large diameter pipes (the photo shows the 100" type)
This internal clamp for large diameter pipes (from 80” up) is equipped with 3 hydraulic cylinder crowns that expand one by one at the same time with synchronized stroke of the separate cylinders. An electric motor drives the hydraulic pumps. Four rubberized motor-driven wheels drive it inside the pipe and for safety reasons the personnel assigned to the works can pass through its chassis. It is also equipped with a hydraulic winch so as to work and move safely even on an incline.

Hydraulic conversion kit to transform old caterpillar mechanical pipelayers in hydraulic driven winches
The kit can be places instead of the original mechanical one without modifications to tractor frame. The two drums are mounted on the same axle like the original and thanks to a special proportional hydraulic distributor with “Load Sensing” control, both winches can be used at the same time by one joy-stick.
