Self propelled machine for laying underwater cable - has bucket chain excavator between tracks with rubber treads, and centre of gravity which coincides with turning centre

摘要

The machine is self-propelled and used for laying submarine cables. It is directed by an operator in an enclosed compartment or by remote control from the mother ship. The power unit is behind the compartment, and the machine is moved on tracks whose treads are made from rubber. A trench is excavated by a bucket chain under the machine and between its driving tracks. The cable passes through a guide over the excavator chain.
