This invention was a portable pushing and pulling apparatus for in-conduit cable installations, the aforementioned device is of the type which comprises a casing that, viewed from above, is in the shape of a rectangle and is formed of a base (1) joined to a cylindrical handle (4), a cover (2), a hinged joint (3) connecting the base (1) and the cover (2) on a short side, a set of screws (40) for ensuring the cover's closure on the base, a drive capstan (25) driven by a rotary drive shaft (28) mounted in the handle (4), an idler disk (29) with an axle parallel to the capstan (25), and both the capstan (25) and the disk (29) are mounted in such a way as to receive a cable (36) to be driven and gripped between them. The invention itself contains in the handle (4), between the drive shaft (28) and the power take-off (53), a torque regulating device at its end, for the torque limiting clutch which indicates the maximum pushing or pulling force selected by the operator.
A portable pushing and pulling apparatus for installing at least one cable in a conduit, the apparatus comprising a casing, which, seen from above, has the shape of a rectangle and includes a base connected to a cylindrical handle, a cover, a hinged joint connecting the base to the cover on a short side, a fastener arrangement to ensure closure of the cover on the base, a drive capstan connected to be driven by a rotary drive shaft which is mounted in the handle, an idler disk with an axle parallel to the capstan, the capstan and disk being mounted so as to receive the cable and being arranged so that cable can be driven and gripped between them, the drive shaft including a power take-off, and an end torque regulator located, in the handle, between the drive shaft and the power take-off, the end torque regulator including a torque limiting clutch and an indicator for indicating the value of a maximum pushing or pulling force selected by the operator.
