66" TANDEM VIBRATORY ROLLER

The operating weight of the unit shall be no less than 20,462 lbs. and will be divided as follows: front drum weight of I 0,322 lbs. and rear drum weight of l 0, 140 lbs.

The unit shall be equipped with two steel drums having a minimum width of 66.1 ", a minimum diameter of 47.2" and a shell thickness of no less than .70". The unit shall be equipped with a hydraulic offset that enables the roller to offset to either side a minimum of 6. 7" for easy operation along curbs and cul-de-sacs. Curb clearance should be a minimum of 31.5" and ground clearance should not be less than 13".

The unit shall be equipped with a four cylinder, water cooled, turbo-charged, diesel engine capable of producing a minimum of 113 SAE horsepower at 2,300 RPM. The engine shall meet all of the latest North American exhaust emission standards.

The capacity of the fuel tank shall be no less than 45 US gallons and be equipped with clean-out covers to facilitate the removal of foreign materials that may be introduced into the fuel tank.

The drive system shall be hydrostatic, operating both front and rear drums. Ground speed shall be infinitely variable in both forward and reverse between 0 and 6.5 MPH and have an automatic speed control system. The unit shall be able to operate on a 41

% grade with both drums vibrating and a 46% grade in the static mode.

The vibration system shall be designed with a variable displacement pump feeding a fixed displacement motor for each drum allowing independent control of amplitude frequency for each drum. The unit shall be able to produce a minimum of 18,000 I bs.

of centrifugal force per drum when vibrating at 2,520 VPM and .024" of amplitude or 13,500 lbs. of centrifugal force per drum when vibrating at 3,000 VPM and .013" of amplitude. The independently adjustable vibration frequency and amplitude selection shall be operator controlled with a digital readout located on the control panel, independently, for each drum. The unit will be capable of vibrating the front drum only, the rear drum only or both drums at the operator's option. The control for engaging the vibration system shall be conveniently located in the forward and reverse control lever. The unit shall have an automatic speed control so that vibration impacts and roller speed can be matched and controlled by the operator.

The roller shall be equipped with hydrostatic power steering with a true center point articulation of a plus or minus 30 degree steering angle and a plus or minus 10 degree frame oscillation. The inside turning radius shall not exceed 238.2".

Brakes:

Water System:

The unit shall incorporate hydrodynamic braking at both the front and rear drums and the parking break will be engaged when the FNR lever is placed in "park".

For emergency situations, the roller will have an emergency brake which, when activated, will apply the brakes in both drums and destroke the propulsion pump stopping the machine immediately.

The unit shall be equipped with a fully pressurized, filtered, non-corrosive water system having two electrically operated water pumps using one as a backup, where each pump must offer sufficient volume to ensure an adequate supply of water to both front and rear spray bars. In addition, the water system will incorporate a timed interval water release switch capable of providing sufficient water at the operator's option and a manual override switch for constant water flow to both drums. The water capacity shall be no less than 200 US gallons with the water tank(s) constructed of non-corrosive, plastic material. The tank(s) will incorporate a filler strainer and have a water level indicator.

Operator's Platform: The unit shall be equipped with an operator's station that rotates 180 degrees and slides from side to side of the operator's platform. The operator should have a clear view to both front and rear drums. The control lever will be located on the right side of the seat and the control panel should rotate with the operator's station. The seat shall be an adjustable suspension seat that can be adjusted to suit the weight of the operator. The operator's compa11ment shall be readily accessible from either side of the unit and all compartments and operator console shall be lockable providing full vandalism protection. Both front and rear drums will be equipped with spring-loaded scrapers to keep the drums clean and aid in the spread of water on the drum surface.

The unit shall be equipped with the following instruments and warning devices:

Parking brake warning light

Battery discharge warning light

Hour meter

Water and Fuel indicator light

Low engine oil pressure warning light

High hydraulic oil temperature warning light

Air filter restriction indicator light

High engine coolant temperature indicator light

Low alternator charge warning light

Vibration meters

Fuel gauge

Speedometer
