Vehicle-mounted Snow Rotary Brush

The Vehicle-mounted Snow Rotary Brush from Qingzhou Mingxu Supply Chain is designed as an attachment for loaders, backhoe loaders, and other construction vehicles used in winter road maintenance. It combines a hydraulically driven roller brush with wear-resistant mixed steel wire bristles to clear snow and light debris from paved surfaces.

The broom head can be angled left or right through the carrier's hydraulic system, and the unit is built with a quick-connect bracket for installation and removal. Support legs are included for stable parking when the attachment is not in use. The equipment is intended for use on highways, factory yards, residential roads, and airport auxiliary surfaces.

Basic Configuration

Operating Principle

Hydraulic oil from the carrier vehicle flows into the brush motor, driving the sweeping roller at a consistent speed. The bristles contact the road surface and move snow to the side as the vehicle advances. The floating spring brackets allow the roller to follow changes in surface height, maintaining contact while reducing the risk of bristle damage from curbs or speed bumps. When the broom is raised, the roller lifts clear of the ground for transport or storage.

Operating Instructions

1. Pre-operation preparation: Park the carrier on level ground and shut down the engine. Connect the quick-mount bracket and secure the hydraulic fittings. Check bristle condition and look for hydraulic leaks. Remove any ice or branches wrapped around the roller.

2. No-load test: Start the vehicle and test the lifting and angle adjustment functions without load. Confirm the roller rotates smoothly with no abnormal noise or vibration.

3. Snow sweeping operation: Lower the broom to the ground and drive forward at a steady low speed. Slow down in areas of thick snow to reduce bristle wear. Use the hydraulic angle adjustment to direct snow to either side. When cleaning along curbs, angle the broom slightly to reach the edge.

4. Obstacle handling: Raise the roller before passing over large stones, steps, or other hard obstacles. Do not grind the brush against fixed objects. If the hydraulic oil temperature rises abnormally, stop and check the system.

5. Shutdown and storage: Lift the roller about 20 cm off the ground and run it briefly to shake off ice and snow. Shut off the hydraulic supply and clean debris from the roller gaps. For long-term storage, fully raise the broom, drain residual water from hydraulic lines, and apply anti-rust protection.

Key Features

1. Universal mounting. The quick-connect bracket allows installation on different carrier machines, including sanitation trucks and loaders. This reduces the need to purchase a dedicated snow sweeper for seasonal use.

2. Floating buffer suspension. The spring-mounted brackets allow the brush to follow road contours and absorb impacts from speed bumps and minor surface irregularities. This helps protect both the bristles and the pavement.

3. Mixed bristle construction. Inner steel wire bristles break through compacted snow, while outer nylon filaments protect the road surface. The combination is intended to extend brush life compared with all-nylon brushes in low-temperature conditions.

4. Hydraulic angle control. The broom can be angled left or right from the cab, allowing snow to be directed to the desired side without stopping the machine.

Brush Material and Low-Temperature Performance

The Vehicle-mounted Snow Rotary Brush uses a composite arrangement of steel wire and nylon filaments. The inner layer consists of high-carbon steel wire with a diameter of 0.8–1.2 mm, arranged in a dense helical pattern to apply cutting force to compacted snow and thin ice. The outer layer is made of nylon filaments with a diameter of 1.0–1.5 mm, which protect asphalt and concrete surfaces from scratching during operation.

The nylon material is modified for low-temperature use. At sub-zero temperatures, standard nylon becomes brittle and prone to fracture. The nylon used in this brush is compounded with low-temperature plasticizers, allowing it to maintain flexibility down to approximately -30°C. This reduces the number of broken filaments that need to be swept up after each shift.

Field feedback from municipal users indicates that the mixed brush lasts approximately one and a half times longer than an all-nylon brush when used on roads with frequent freeze-thaw cycles. The steel wire core wears gradually and remains effective until the brush diameter is reduced by about 40%, at which point the brush should be replaced. Users in areas with frequent black ice have reported that the steel wire portion helps break thin ice layers that would otherwise remain after a nylon-only sweep.

Mounting System and Customization

The quick-mount bracket is designed to fit standard loader and backhoe loader couplers. It uses a pin-lock system that can be engaged or released without tools in most cases. The bracket includes alignment guides to simplify attachment when the operator is working alone. Hydraulic connections use flat-face quick couplers, which reduce oil spillage during connection and disconnection.

For carriers that do not use a standard coupler, adapter plates can be produced. Drawings or measurements of the carrier's mounting interface are required during the order stage. The adapter plate is welded to match the existing pin spacing and bore diameter, and is tested before shipment.

Brush width, roller diameter, and bristle density can be adjusted for specific applications. Wider brushes clear more area per pass but require higher hydraulic flow and may exceed the capacity of smaller loaders. A standard 2-meter brush is suitable for most municipal work; 2.5-meter and 3-meter versions are available for large open areas. Brush pressure can be set at the factory according to the expected road surface type.

Typical Applications

1. Municipal sanitation roads: routine snow sweeping on urban main and branch roads, rural highways, sidewalks, and non-motorized lanes.

2. Expressway service areas: clearing thin snow and ice from toll stations, parking lots, and ramps to maintain traffic safety.

3. Industrial and logistics parks: snow removal from factory roads, truck loading platforms, and parking areas.

4. Mine and aggregate stockyards: clearing floating snow and ice from access roads and batching plant pavements.

5. Residential and campus areas: gentle snow cleaning for residential quarters, schools, and park squares without damaging floor tiles.

6. Airport and port yards: lightweight rapid snow removal on auxiliary taxiways and port outdoor roads.

Warranty and Support

The snow broom attachment is covered for 12 months or 1,000 working hours, whichever comes first. Major components including the hydraulic motor, brush shaft bearings, and mounting frame are covered for 6 months. Wear items such as brush bristles and hydraulic seals are not included in the warranty. Replacement parts can be supplied; shipping and installation labor are the customer's responsibility.

FAQ

Q1: How often do the brush bristles need to be replaced?
A1: Replacement frequency depends on the amount of snow cleared, road surface type, and operating speed. Under normal municipal use, bristles typically last one to two winter seasons. Regular inspection is recommended, and bristles should be replaced when they become shorter than half their original length or when steel wires begin to break off in clusters.

Q2: Can the snow broom be used on gravel or unpaved roads?
A2: The broom is designed primarily for paved surfaces. On gravel roads, the brush may pick up loose stones and cause accelerated bristle wear. If use on unpaved surfaces is necessary, a reduced ground pressure setting and lower speed are recommended, and bristle condition should be checked more frequently.

Q3: What hydraulic flow rate is required from the carrier vehicle?
A3: The required flow rate depends on the brush size. A standard 2-meter brush typically requires a hydraulic flow of 40–80 L/min at a pressure of 16–20 MPa. The carrier's auxiliary hydraulic circuit should be checked against these figures before installation.

Q4: Is the broom difficult to install on an existing loader?
A4: Installation is designed to be straightforward using the quick-connect bracket. After the initial mounting, connecting the hydraulic lines and testing the lift and angle functions usually takes less than 30 minutes. A detailed installation manual is provided with each unit.
