Sno-Way 28V SERIES
Municipal Specifications

The Sno-Way 28V snow plow is constructed for the commercial plower, business owner, municipality, or other large institution with 3/4 ton to 1 ton trucks. The 28V snow plow ensures that plowers make more money with increased efficiency. The V plow is quicker, more responsive, easier to manipulate in tight conditions, and can scoop up to four yards of snow in a single pass. Combined with Sno-Way's optional Down Pressure™ System, this snow plow has more cutting edge pressure than any plow in its class.

Blade Assembly

• Moldboard-16 Gauge high strength steel roll formed to a 14" radius, optional polycarbonate inserts or optional stainless steel inserts.
• Laser cut ribs and supports of high strength low alloy steel - robot welded to support steel component top and lower formed rails.
• Cutting edge system comprised of two ½" X 6" high carbon steel C1080 wing edges, with a center tower edge of flexible high density UV protected high abrasion resistant polymer.
• Cutting edges mounted with Grade 5 fasteners.
• Trip Springs- Two full load trip springs 2-5/16" OD X .438 diameter made of oil tempered spring steel attached with two 5/8" X 6" eyebolts.
• Tripping position is a full blade 50° angle and all position trip pattern with forward wing relief.
• Blade trip pivot is secured by two ¾" Grade 5 pivot locking pins through the lower tower assembly.
• Blade Guides- Two high visibility blade markers.
• Plowing angles are a full 30° left and right, full frontal position scoop to V position, and all angles in between. Wing functions are independent or in unison.
• Disc Shoes-Three special alloy abrasion resistant heavy duty cast shoes.
• Standard center deflector.
• Patented contour following power tower with 10° pivot for following uneven terrain.

Main Frame

• Formed side and rear channels of 2-1/2" X 2-1/2" X 5/16", and 2-1/2" X 2-1/2" X 1/4" steel, sandwiched with high strength low alloy plate and robot welded.
• Pump platform is a formed channel plate that is robot welded.
• Lift Mechanism- Robot welded high strength low alloy steel lift bar and bell crank assembly to provide for direct linkage to the plow A-frame for lifting and lowering plow assembly.

Power Tower

• Specially designed high strength low alloy steel center tower with 12" frontal push surface. Center wearstrip mounts to this tower and closes all gaps between tower and wings.
• One inch pivot wing connector pins.
• Adjustable contour stops to accommodate vehicle heights.
• Patented contour following floating head with 10° pivot allows for more consistent cutting edge contact on uneven terrain.

Vehicle Mounts

• Custom designed robotic welded high strength low alloy steel sub frames fastened with Grade 8 hardware for secure attachment to the vehicle frame, meeting all Federal Motor Vehicle Safety Standards (FMVSS).
• Attachment- A-frame is secured to the vehicle sub frame at three points utilizing three 3/4" diameter loop handle pins with spring clip pins.

Paint

• All snow plow components are prepped in a six or eight stage wash system, rinsed with phosphate and finally rinsed with reverse osmosis water for the ultimate in paint preparation.
• All snow plow components are powder painted using air to fluidize the powder and applied with a calibrated paint gun. Following the application of powder, components are uniformly processed through a gas fired oven where the parts are brought up to a pre-established temperature to assure proper adhesion and curing.

Hydraulics

• Electric solenoid activated valves.
• Electro-Hydraulic power unit consisting of a fixed clearance displacement gear pump with 2000 psi relief and direct tang driven by a 4-1/2" 12 Volt DC motor. Hydraulic power unit is protected by a removable polyethylene cover for protection from the elements.
• Pump with filter screen and return tube immersed in a polyethylene reservoir.
• Valve manifold is constructed of aluminum and contains six solenoid cartridge poppet calves for gravity system. Cushion relief valves are set at 2400 psi and has a changeable restrictor orifice to adjust plow drop speed.
• Hydraulic Cylinders- One 2-1/2" X 4" lift cylinder and two 2-1/4" X 9" angling cylinders each with a V packing, wiper ring and adjustable gland nut. All cylinders are connected to the hydraulic power unit with 1/4" 5000 psi rated hoses.
• Hydraulic power unit is controlled by a micro-processor based control. Plow functions can be performed independently or in unison.
• Hydraulic power unit is grounded to the vehicle negative circuit.
• Battery power cable is connected to a 150 amp thermo circuit breaker for protection.
• Hydraulic Fluid- Hydraulic fluid is low temperature, anti-foam, air craft quality hydraulic fluid with a pour point of -70 degrees Fahrenheit.

Hydraulic Down Pressure System Option

• Hydraulic Down Pressure units would utilize the same specifications as above with the addition of two cartridge poppet valves, a relief valve and an electric pressure switch. Use of hydraulic down pressure system is selected by the operator and does not operate without being selected.

Light Kit

• Rectangular dual beam halogen headlamps with combination park and turn signals.
• Vehicle specific pre-wired harness with plug in adapter to eliminate headlamp wire splicing.
• Plow and vehicle headlights are automatically selected through a relay system.
• Heavy duty flasher (when required).
• FMVSS 108 compliance for lights.
• Light kit is fully removed from the vehicle as part of the snowplow assembly leaving a clean vehicle profile.

Snow Plow Removal

• All snow plow components are removed as one assembly from the vehicle by disconnecting mounting pins and harnesses, leaving a clean vehicle profile.
