Exhibit H Specifications for a Wheel Type Excavator

The following specifications describe the minimum requirements for heavy-duty, multi-purpose, hydraulic powered, wheeled type excavators, with a minimum 48,500 Lbs. operating weight. The equipment shall be new, of current design and manufacture, and a production model. Any additions, deletions, or variations from the following specifications must be noted or the equipment will be rejected. Any standard items appearing in the manufacturer’s regular published specifications shall be included unless otherwise noted.

Parts and service for the equipment should be readily available within the State of Illinois.

Unless otherwise specified, the equipment shall be complete in all parts and ready for immediate use upon delivery.

Make:

Model:

Manufacturer:

The State reserves the right to waive minor informalities, deficiencies, or technical variances which by their nature are restrictive to a given manufacturer, if in its’ judgement, it would be in the best interest of the State.

Size:

The excavator shall have a minimum SAE compliant operating weight of 48,500 lbs. when equipped per specifications.

Boom, Arm, Buckets, and Accessories:

The excavator shall be furnished with a “one-piece” standard length boom with an approximate length of 16’.

The excavator shall be furnished with an arm (stick) length of no less than 9’-0”.

Equipped per specifications, this excavator shall have an approximate digging depth of 19’-11” to dig to an 8’-0” level bottom excavation.

Equipped per specifications; the excavator shall have an approximate digging depth of 20’-6”.

Reach at ground level shall be approximately 32’-0”.

The boom shall be furnished with a boom holding or anti-drift valve for precise boom control while setting pipe, concrete barrier curb, or other similar functions.

Equipped per specifications the excavator shall have a transport height no greater than 12’.

This excavator may be used to move and place concrete barrier sections. These barrier sections weigh 5,000± pounds each and must be set from tractor trailers and removed at the completion of the construction project. Many of these projects will be on bridge decks requiring the use of a rubber-tired machine. The capacities specified are minimums believed necessary to safely complete this task.

Minimum SAE lifting capacity at ground level over the end and fully extended shall be no less than 7,000 lbs. equipped per specifications, including counterweight and deployed stabilizers.

The ISO lifting capacity over-the-side at 20’-0” reach with the specified 9’-0” arm with outriggers deployed, extended 20’ above ground shall be a minimum of 11,000 pounds.

The ISO lifting capacity over-the-front at 20’-0” reach with the specified 9’-0” arm with outriggers deployed, at 5’ above ground line shall be at shall be a minimum of 15,300 pounds.

The excavator equipped with the 9’ 0” arm shall have an ISO rated bucket digging force of 22,425 pounds.

Counter weighting is extremely important in ensuring the stability of the machine while operating in uneven terrain. The machine will be operated in severe conditions and be used in response to natural and manmade disasters as well as routine ditch cleaning, setting barrier curb sections, and setting pipe and entrance culverts. Proper balance is important to promote operator and all worker’s safety. Please list below the counter weighting provided with this machine, keeping in mind the options specified with the base machine.

This machine is to be furnished with a coupler system to allow the operator to switch buckets or attachments. This device may be of the manufacturers design or purchased from a supplier. This coupler shall also be compatible with the hydraulic “thumb” specified. The use of this type coupler serves several purposes. First it is compatible with and assortment of buckets already owned by an entity and allows the machine to perform the routine ditch cleaning operations with minimal repositioning of the machine. Second and most important, the use of this device has been shown to reduce injuries when manually removing, aligning, and reinstalling pins in both the end of the boom and at the bucket. Manually removing pins, realigning pins is more difficult and dangerous when performed on the uneven terrain of a construction work site. The size of the coupler shall be as recommended by the manufacturer of the machine with consideration given to the buckets and features specified.

The following two (2) buckets shall be furnished with the wheeled excavator. All capacities listed shall be measured using SAE heaped standards:

· Standard 36” wide bucket ditch type, with five (5) replaceable type teeth and a .95 cu. yd. capacity.

· A 60” wide grading, ditch cleaning bucket with smooth cutting edge. The bucket shall have a .75 cubic yard capacity.

It is noted that manufacturer’s bucket capacities may vary.

Diesel Engine:

The excavator shall be powered by a current production, liquid cooled, turbo charged, diesel engine with an SAE J1349 net horsepower minimum of 165 and minimum displacement of 400 cu. in.

The machine shall require entry of an electronic “PIN” code to start the engine and run the features of the excavator.

Cooling System:

Pressurized liquid cooling system equipped with a thermostat. System shall be filled with manufacturer’s approved extended life antifreeze.

Transmission:

Hydrostatic drive to each wheel shall be provided by the transmission mounted directly on the rear axle for protection and increased ground clearance. Travel speeds shall be controlled by an auto-shift feature for high/low utilizing an auto or “intelligent” shift feature. These functions shall include both forward and reverse directions and from 0 to approximately 22.0 MPH.

The excavator shall include a cruise control switch that allows the operator to select the travel speed.

The excavator shall include a “ride-control” feature to promote smoother rides on rough terrain or highways. This feature shall be operator controlled.

Steering:

The operator will have a steering wheel for the placement of the wheeled excavator. All boom functions shall be controlled by joystick controls. Repositioning the machine while digging or operating is accomplished using a “slider switch” on one of the joy sticks.

Brakes:

The excavator shall be equipped with a disc brake system acting directly on the hub to prevent planetary gear backlash.

Undercarriage:

The undercarriage shall be constructed of welded structural steel. The four (4) outriggers shall be an integral part of the undercarriage and be located at each corner.

Wheelbase length shall be approximately 8’-6”.

The excavator shall be equipped with tandem (2) tires and wheels at each corner. They shall be 11.00-20 duals PR16 ply with tapered lugs to promote self-cleaning and to enhance traction in heavy dirt and mud. Note: Spacer rings must be included.
