Abstract

A cable embedding device comprising a framework for supporting and hydraulically raising and lowering a rock saw and a cable carrying bellmouth relative to two spaced-apart sled-type runners. Each sled carries part of a jet spray system and an eductor system, which spray system creates a slurry and which eductor system carries and discharges the slurry to the back of the device. A hinge and a hinge-roller assembly connect the framework to the device for relative movement therebetween. The bellmouth is shaped to curve around the rock saw, and its pedestal foot supports the bellmouth in the cable embedding and/or trenching operation.
