Power Ahead with the Revi 550 Tractor

Included are three sets of wheels together with a set of spacers and an adjustable gantry to provide a spectrum of different heights and axle widths to suit the tractor for a range of pipe diameters. Durable moulded-on rubber tyres with a silt-cutting rubber stud pattern are fitted to the two smaller sizes. The largest are pneumatic. The gearing ratio provides approximately the Water Industry Model Contract recommended survey speeds for 150mm, 300mm, and 450mm pipes when the small, medium and large wheel sets respectively are fitted. Careful wheel selection combined with a powerful motor ensure that the full 200 metres of cable is available for use.

The camera head can be panned to ±120°. Rotation is continuous through 360° and the rate of both axes is controllable.

The high-sensitivity Sony HAD CCD sensor and lensing used deliver a stunningly detailed picture across the full range of the 10 x optical zoom. There are both manual and automatic modes for focus, aperture and white balance.

An adjustable cluster of four powerful Lumiled LED's are fitted to the pan and rotate head to provide lighting for smaller diameter pipes. An independently controlled demountable twin 20 Watt halogen light head is supplied as standard.

An "always on" 33KHz sonde is fitted to the tractor body. 

An on-board gauge communicates continuously with a low-pressure warning system in the base unit to permit the operator to maintain positive pressure thus ensuring contaminates cannot enter the tractor
