This Large Vehicle-mounted Rotary Snow Brush is built for high-capacity snow clearing on expressways, airport service roads and urban arterial routes. It mounts to the front of heavy sanitation trucks or dedicated snow-clearing chassis. The standard roller is assembled from high-density polypropylene segments and powered by an imported hydraulic motor. An optional steel wire composite brush is available for compacted snow and light ice conditions. A four-link floating mechanism allows the brush to follow potholes, curbs and cross slopes while keeping the bristles in contact with the ground. Working width, hydraulic power and anti-freezing configurations can be adjusted to match different carrier vehicles and road classes.

Working Principle

Hydraulic oil from the carrier vehicle flows to the drive motor, which rotates the brush roller. Bristles strip snow from the pavement and throw it to the side. The brush assembly sits on a four-link floating frame with spring buffers, so it rises and falls over surface irregularities without losing ground contact. A hydraulic control valve changes the left-right deflection angle, while the lifting mechanism raises the brush for obstacle avoidance and storage. Because the hydraulic circuit is independent of the travel drive, brush speed can be matched to vehicle speed and snow depth.

Operating Instructions and Maintenance

Pre-operation Preparation

• Park the carrier vehicle on flat, hard ground. Shut down the engine, attach the quick-mount frame and insert the locking pins. For independently powered models, connect the auxiliary engine fuel line and hydraulic hoses, then tighten all sealed joints.
• Check the four-link springs for elasticity, examine bristle wear, and look for corrosion or deformation on the stainless steel hood. Remove ice and wire wrapped around the roller. Inspect hydraulic lines for leaks.
• Start the power unit without load. Operate the lift, left-right deflection and floating compensation several times. Confirm the roller turns smoothly with no unusual noise before moving to the work area.

Snow Cleaning Operation

• Lower the brush until the bristles lightly touch the road. Typical operating speed is 10 to 20 km/h on municipal roads and 15 to 30 km/h on expressways, subject to snow depth, surface conditions and carrier performance. Reduce speed in deep snow to limit bristle wear.
• For main roads, set a single-side deflection angle so snow is thrown to the shoulder. On ramps and toll plazas, adjust the angle to clean edge lines and residual ice.
• Let the four-link floating system carry the brush over manhole covers, speed bumps and raised curbs. Do not strike hard obstacles at high speed; this can deform the linkage or break bristles.

Storage and Anti-freezing Maintenance

• Raise the brush about 40 cm and drive without load for about two minutes to shake off ice, snow and salt residue from the roller and hood.
• Shut off engine power and disconnect the hydraulic circuit. Remove the quick pins, separate the attachment, and clean ice from between the bristles. Apply anti-rust grease to linkage pins and hydraulic fittings.
• For seasonal storage, keep the brush raised and place wood blocks under the roller. Drain water from hydraulic lines and the auxiliary engine cooling system to avoid freeze damage.

Design and Construction

1. Four-link wheel-free contour structure. The Large Vehicle-mounted Rotary Snow Brush does not use bottom support wheels. Instead, a four-link system with springs lets the roller follow the road profile. This reduces hard contact points and helps lower the risk of scratches on asphalt and decorative pavement, which is a common requirement in municipal tenders.

2. Stainless steel hood. The cover over the brush is made from stainless steel to resist corrosion caused by deicing salt and meltwater. In northern regions where salt is applied frequently, this material generally offers better corrosion resistance than painted steel.

3. Gear direct-drive hydraulic motor. The motor connects to the roller through gears rather than belts. This avoids belt slip and helps maintain torque at higher travel speeds, making the brush suitable for long highway runs.

4. High-density polypropylene brush segments as standard. The standard brush uses staggered polypropylene bristles that grip and sweep snow effectively. The material performs well at low temperatures and resists abrasion. For compacted snow or light ice, an optional steel wire composite brush is available.

Application Scenarios

• Expressway traffic lines: Clearing floating snow and thin ice from main lanes, ramps, toll stations and service areas to keep traffic moving during storms.
• Urban municipal roads: Routine winter cleaning on ring roads, arterials and sidewalks. Often purchased in batches by city sanitation departments.
• Airport service roads and auxiliary areas: Snow removal on airport service roads, aprons and cargo areas where rapid clearing of loose snow and surface residue is required.
• Logistics and industrial parks: Clearing outer ring roads, loading platforms and large parking areas to avoid disruptions.
• National and provincial highways: Regional snow clearing on long-distance routes, often used by road administration emergency teams.
• Port yards: Fast removal of thin snow and broken ice from freight lanes and container storage areas.

Technical Specifications

Key specification considerations for your site:

• Working width (2500 to 3500 mm): Select a width that matches your lane width or required clearing capacity per pass.
• Recommended operating speed (10–30 km/h): This is the typical range for effective snow removal. Adjust based on snow depth, road surface and carrier stability.
• Snow removal thickness (≤150 mm): This is the rated maximum for loose snow in one pass under normal conditions. Dense, wet or compacted snow may require lower speed or multiple passes.
• Snow throwing distance (5 to 10 m): Ensure the discharge area is clear of traffic, pedestrians and obstacles.
• Attachment weight (740 kg): Verify that the carrier vehicle can support the attachment without exceeding axle load limits.
• Hydraulic flow and pressure: These must be matched to the carrier vehicle. Contact our technical team with your vehicle model for the correct motor configuration.

Frequently Asked Questions

What is the difference between the standard brush and the optional steel wire composite brush?

The standard brush is made of high-density polypropylene segments, suitable for loose snow and routine clearing. The optional steel wire composite brush is designed for compacted snow and light ice. It uses a mix of steel wire and polypropylene to increase cutting ability. The choice depends on typical snow conditions in your area.

What type of carrier vehicle is required?

The brush is designed for heavy sanitation trucks and municipal chassis with front-mount capability and sufficient hydraulic flow. The hydraulic motor displacement is matched to the vehicle. Provide your vehicle model to our technical team so we can confirm compatibility and recommend the correct configuration.

How does the four-link floating mechanism work?

The brush assembly is mounted on four linkage arms with spring buffers. As the ground level changes, the arms extend or compress so the roller stays in contact with the surface. This improves cleaning consistency and reduces stress on the frame and bristles. It also helps the brush pass over manhole covers and curbs without manual adjustment.

Can the working width and motor configuration be customized?

Yes. Working width, hydraulic motor size and anti-freezing reinforcement can be adjusted to fit the carrier vehicle and the road conditions. Bulk orders for large winter maintenance projects are accepted.

What is the recommended maintenance for the brush during winter season?

Inspect the brush segments and hydraulic hoses before each shift. After each operation, remove ice and salt residue. Grease linkage pins weekly during heavy use. Check hydraulic oil level and leaks regularly. If the brush is stored for more than a week, lift it off the ground and cover the roller to prevent ice buildup.
