Slipform paver YG-KB series

Product Overview
A concrete curb machine is heavy-duty road construction equipment designed for continuous in-situ slipform pouring of concrete curbs and gutters. The machine uses a screw feeder to convey fresh concrete into a forming mold and a high-frequency vibrator to ensure compaction and a uniform finish. It replaces precast methods and is used for highway shoulders, urban medians and landscape edging, handling straight runs and complex curves with accurate guidance when fitted with automatic steering.

Pro Tip
Verify steering and tracking precision for projects with curves: advanced dual automatic steering systems minimize lateral deviation and maintain consistent pavement width across radii.

Applications

• Municipal works: parking lot perimeters, city medians and streetscape curbs.
• Infrastructure: rapid edging for drainage channels, highway shoulder curbs and airport perimeter drains (with appropriate configuration).
• Landscape and special structures: continuous landscape curbing, jersey barrier-style elements and custom curb profiles.

Key Features

• Dual automatic steering system to reduce position deviation on curves by over 95% and maintain precise pavement width.
• Anti-slip self-locking function to hold set speed on slopes and prevent sliding during gutter formation.
• Robust 4WD drive and powertrain: typically equipped with a 65 kW four-cylinder turbo diesel engine for consistent material push on mild gradients.
• Forming method: high-frequency vibrator with attached vibration motor for improved concrete density and surface quality.
• Screw feeder driven by a high-torque hydraulic motor with wear-resistant blades; recommended aggregate size 5–16 mm to avoid clogging.
• Two-stage hydraulic cooling (water + air) to keep oil temperatures low and extend pump/motor life.

Operational Notes & Benefits

• Suitable for continuous slipform curb and gutter laying on highways, urban roads, parking areas and landscape borders.
• Dual steering and anti-slip systems improve line accuracy, safety and repeatability on curved alignments and slopes.
• Adjustable paving speed accommodates different mix designs and on-site conditions.
• Multiple configurations (crawler or chassis, various mold strokes) allow matching to project requirements and site access limitations.

FAQ Highlights

• Recommended aggregate size: 5–16 mm for reliable screw feeder performance.
• Maintenance: two-stage cooling reduces hydraulic temperatures and lowers maintenance frequency and component wear.
