This 165HP Small Paving Grader (model LG165) is a compact, high-precision equipment designed for fine grading in pavement construction, especially in urban and residential areas with limited space. It weighs 15000 kg and features a 3660 mm-wide grading blade—slightly wider than standard small graders—enabling efficient grading while maintaining a compact footprint (overall length: 8900mm, width: 2500mm). The machine incorporates a digital control system that allows operators to store up to 10 grading presets (e.g., road shoulder slope, parking lot flatness), reducing setup time when switching between tasks. Its high precision (±2mm grading accuracy) and compact design make it ideal for urban road paving, parking lot construction.
Engine Performance & Fuel Efficiency: Powered by a 165HP Cummins diesel engine (125 kW) with inter-cooling supercharging, which delivers strong power for fine grading tasks while maintaining low fuel consumption. The engine’s electronic control unit (ECU) optimizes fuel injection based on load demand, achieving a fuel efficiency of 8-10 L/h—8% lower than similar models. The inter-cooling system reduces intake air temperature, improving engine power output and extending service life by 20% in high-temperature environments (e.g., summer urban construction).
Hydraulic Control & Grading Precision: The hydraulic system uses two Husco 5-way control valves and imported equalizing valves, ensuring smooth, precise blade movement. The valves’ low friction design reduces hydraulic oil temperature, extending oil life to 4000 operating hours. The grading blade is controlled by four hydraulic cylinders (two for height, two for angle), enabling fine adjustments (±1mm) to achieve the required flatness. The optional ultrasonic sensors can detect the height of existing pavement, allowing the machine to grade the new layer to match the surrounding surface seamlessly.
Urban road asphalt paving preparation, including fine grading of the base layer (subgrade or base course) to ensure smooth asphalt application and uniform thickness (4-6cm for surface courses)
Parking lot and plaza level grading, ensuring flat surfaces that prevent water accumulation and meet accessibility standards (e.g., wheelchair ramps with 1:12 slope)
Highway shoulder trimming and maintenance, including adjusting shoulder slope (3-5% grade) to improve drainage and prevent pavement damage from water infiltration
Residential community road construction, including grading narrow roads (3-4m width) and adjusting curbside slopes to match sidewalk height
Golf course and sports field preparation, including fine grading of fairways or field surfaces to ensure level playing conditions
Q: What is the minimum turning radius, and how does it adapt to narrow urban spaces?
A: The minimum turning radius is 7500 mm, which is 15% smaller than standard medium-sized graders. This compact turning radius allows the machine to maneuver in narrow urban spaces, such as between buildings in residential areas (road width: 3-4m) or small parking lots, without damaging nearby structures or landscape. The machine’s short wheelbase (4200mm) further enhances its maneuverability in tight spaces.
Q: How thick a layer can it grade, and is it suitable for both thick base layers and thin surface layers?
A: It can grade layers with a thickness ranging from 50mm (thin surface layers, e.g., asphalt leveling) to 300mm (thick base layers, e.g., roadbed subgrade). For thick layers, the machine can make multiple passes (2-3 passes) to achieve the required thickness, while for thin layers, the high-precision hydraulic system ensures uniform grading in a single pass. The grading blade’s adjustable height (maximum lift: 500mm) allows it to handle both thick and thin layers effectively.
Q: Does it support OEM customization, and what additional options are available for specific projects?
A: Yes, it supports OEM customization to meet project-specific needs. Common customization options include: blade size adjustment (3300mm to 3900mm), addition of GPS or laser leveling systems for higher precision, installation of snow removal attachments (e.g., snow wings), and customization of cab colors to match the customer’s fleet. Additionally, the manufacturer can provide custom grading presets for specific tasks (e.g., airport taxiway slope, wheelchair ramp slope) to reduce operator setup time.
