  • Apparatus for pulling cable through underground conduit
    Patent number: 4469306
    Abstract: A cable pulling apparatus includes a winch line on a drum supported on a bed of a vehicle and driven by a motor with a clutch between the motor and drum and a brake associated with the drum. A boom defines a guide for the winch line into a manhole into alignment with an underground conduit and a mandrel is attachable to the winch line. An air gun has one end received into the underground conduit and is expansible into engagement with the conduit and a compressor assembly is attached to the opposite end to propel the mandrel and winch line through the underground conduit. A cable is then attached to the winch line and is drawn through the conduit by driving the drum. A blower and a water pump are also supported on the bed to remove gases and water from the manhole.
