Title of Invention	AN IMPROVED UNDERGROUND TELEPHONE CABLE PULLING SYSTEM
Abstract	Improved underground telephone cable pulling system (1) as per present invention is shown to comprise a hydraulic winch (2) worked, by a suitable prime mover (3) which, in this case, is a diesel engine. The prime movgr (3) works a hydraulic pump (5) to create desired pressure of around 25-1tX> Kg/Cm , The fluid under pressure is made to pass through a known flow control valve (6) having a direction control valve (7) and pressure setting valve (9) which in turn operates a reduction gear box (10), on the end shaft (11) of which there is provided a capstan drum (12) having few loops (13) of nylon rope (17), which is used to pull the optical fibre telephone cable (15) wound on a cable drum (23) plsced at the edge (24) of the aanhole (25). The tre% end of the said sock (16) is connected to the swivel joint (1S) in the known manner, the other end of which is firmly connected to the free end (19) of the nylon rope (17) which 13 initially passed through one of the plurality of ducts (21). The said ducts are actually pv^ pipes laid underground and meant for the said optic fibre telephone cable.
