13. STEERING SYSTEM: The snow blower shall have power assisted, synchronized, all wheel steering, controlled from the operator’s position. Four-wheel steering shall be electronically coordinated through the standard steering wheel. A selector switch within easy reach of the operator will provide the option of front steer only, coordinated steer, crab steer and rear steer. An indicator shall be provided in the cab to display mode selected and rear wheel position.

The system shall include safety provisions for dampening the effects of all-wheel steer at higher speeds, but it shall also allow full operation while the vehicle is moving at lower speeds. Dampening shall be related to the vehicle speed.

There shall be a mechanical linkage between the steering wheel and the front axle to assure the ability to control the vehicle in the event of hydraulic or electrical system failure.

An electronically controlled rear axle steering system which operates in conjunction with the mechanically controlled front wheel steering system is required. A visual guide shall be provided to indicate the position of the rear wheels, straight, right or left.

The four steering modes shall consist of the following components and operating features:

a) Front Steer: When in the front mode the vehicle behaves like a conventionally steered vehicle. In this mode, the rear axle remains in the locked position and the rear axle does not steer.

b) Coordinated Steer: This mode gives the operator the tightest turning radius of any of the available modes. When the front axle is steered, the rear axle turns in the opposite direction of the front, which reduces the turning radius and enhances maneuverability. This mode also has a deadband feature. Deadband allows the vehicle’s front axle to be turned a predetermined number of degrees in either direction before the rear axle steers. The deadband varies according to the speed of the vehicle.

c) Crab Steer: When the front axle is steered, the rear axle steers in the same direction as the front axle. This makes the vehicle travel in a diagonal motion, sometimes called “crab walking”.

d) Electronic or Manual Rear Steer: When in this mode, the rear axle is controlled manually, independently of the front wheel position. The mechanical lock shall disengage when this mode is activated. A reset center, rear wheel feature is required to assist in relocating the rear axles to the straight-ahead position after manual steering.

A system shall be furnished such that the unit cannot be operated at an unsafe speed.

14. ROTARY SNOW BLOWER HEAD: The rotary snow blower head shall be all mechanical and consist of two stages with ribbon type cutter reels acting as the first stage and an impeller acting as the second stage. The minimum cut width of the snow blower head shall be 110 inches.

A weight transfer system is required to keep approximately 50% ± 5% the weight of the unit on the front axle to maintain equilibrium of the front and rear wheels traction.

Reel ribbons shall have a minimum diameter of 56 inches and be serrated. Ribbons shall be made from high strength steel with a minimum thickness of ½ inch and be reinforced.

The impeller system shall have a minimum diameter of 59 inches with a minimum depth of 24 inches. It shall be designed to be consistent with the capacity of the in-putting reel. The impeller shall consist of a minimum of five (5) blades which shall be individually replaceable. The impeller shall be driven by direct mechanical means and rotation shall be clockwise and shall discharge to the right when viewed from the operator’s position.

The speed ratio between the ribbon reel and the impeller shall be discussed at the Post Award meeting in order to maximize efficiency for Caltrans’ specific work application.

A transmission (drop box) shall be used to transfer power from the auxiliary engine to the blower drive. The transmission shall include a speed reduction gear system to provide the proper torque and speed at the impeller while allowing the engine to operate at the RPM providing maximum efficiency. The transmission (drop box) shall use helical gears with a pressurized lubrication system and shall be approved by the manufacturer for the application. Chain type drop boxes are not acceptable.

The blower drive clutch shall be hydraulically actuated and shall automatically disengage when the engine is turned off.

Both the ribbons and the impeller direction of rotation shall be reversible from within the cab.

The ribbons and impeller shall be protected by either shear pins (bolts), or a torque limiter. All shear pins (bolts) shall be easily accessible for replacement by personnel using common hand tools.

The blade will be designed for high abrasion applications and be hardened and heat treated for maximum impact resistance. With the blower head level with the ground the blade should have an angle between 32 and 55 degrees with the ground.

The blower head shall be equipped with side cutter bars. The side cutter bars shall extend as high as the top of the cab when the blower head is in the up position. The top of the cutter bars shall extend a minimum twelve (12) inches in front of the reels. The cutter bars shall be properly reinforced and braced.

If factory available, the manufacture’s standard skid-shoes shall be installed on the lower outside edges of the blower head in lieu of casters or rollers.

The blower head shall be capable of being hydraulically raised and lowered and locked in the up (dead head) position from within the cab. The blower head shall lift a minimum of twelve (12) inches above ground level and lower a minimum of 3 inches below ground level.

If the blower head is equipped with an “Auto Up” function that raises the blower head when the transmission is shifted into reverse, the operator shall have the ability to turn the function off.

Rocks, six (6) inches in the long line dimension and four (4) inches in the short line dimension shall not cause major damage when passing through the blower during snow clearing operations. This shall be defined to mean that repairs to the unit (by a mechanic) will not be required to continue its operation.

15. DIRECTIONAL CASTING CHUTE: The chute assembly shall rotate in a vertical plane to cast snow to the left or right side of the vehicle through a minimum arc of 130 degrees. The chute shall be able to rotate to be within 15 degrees of flat casting to the right.
