It is capable of transporting stationery head Mainline cameras, rotating head cameras, as well as standard voltage mini cameras (with the appropriate tractor cradle adapters) through water mains, sanitary sewers or storm drains.
Wheel tracking widths are adjustable for pipeline sizes that are 6-inches to 24-inches in diameter when the appropriate axle extensions are used.

It can travel at speeds of up to 45-feet per minute when carrying up to 13-pounds.
Under heavy loading, controls within the tractor automatically increase the torque of the motor.
The Tractor can negotiate 5/8-inch offsets and clear 5/8-inch protruding laterals in 6-inch lines.

POWER

The Mainline Tractor Transport Vehicle's built in power supply receives its control signals and power from the armored single conductor cable.
The power supply also regulates the current and will automatically increase the motor torque if excess loading causes the power supply current to reach 1 Amp.
Power is transferred to the wheels through a low maintenance gear assembly that is enclosed in a sealed housing.
