3.0 GENERAL DESCRIPTION
The GMP AirStream machine is designed to install small diameter cable into underground tubes.
The machine uses a DC servo motor and reduction gearing to drive a pair of flexible belts (both belts are
driven).
The belts are covered with a soft pliable coating to prevent damage to the cable. A range of different coatings
and profiles are available depending on the surface texture of the cable being installed. The belts offer a large
surface area in contact with the cable ensuring high grip with reduced compressive loading.
During installation, the torque applied to the cable by the rollers can be adjusted to prevent the cable buckling
and to prevent damage to the cable. A full range of accessories is available to allow the machine to handle a
wide range of cables and tubes. This machine has the added function of high/low torque selection; this has
been developed to give greater sensitivity when operating in the low torque region aiding the installation of
small cables.
The machine may be placed on the ground or on a support to bring the cable to a suitable height. A separate
reinforced transit housing is provided, this will protect the machine from damage during transit and can be used
as a support for the machine when being used to install cable.
