Product Introduction
The 14 square self-propelled spreader, officially named the 14m³ lime spreader, is a heavy truck chassis integrated lime spreading equipment built for large-scale road subgrade stabilization projects. Classified as a heavy engineering lime paving vehicle and high-output large-capacity lime material spreader, this vehicle-mounted spreader features an enlarged 14-cubic storage tank, dual independent drive chains and a full hydraulic intelligent control system. It evenly distributes hydrated lime, quicklime and cement powder for highway, municipal and rural road base construction, supporting single-side discharge and adjustable spreading width. All operational settings are controlled from the driver's cab with storable preset parameters, drastically lowering manual labor and improving paving uniformity for large construction fleets.
Material & Structural Features
Anti-Corrosion Thickened Carbon Steel Tank: The 14m³ hopper uses high-density carbon steel plate with double-layer anti-rust coating to resist long-term corrosion from alkaline lime powder.
Hot-Forged Alloy Discharge Teeth: Wear-resistant alloy cutter heads endure friction from gravel-mixed lime without rapid blunting, reducing frequent part replacement.
Reinforced Dual 20A Drive Chains: Two parallel heavy chains share heavy load to avoid slipping and tooth jumping under full 14-cubic material weight.
Hydraulic Lifting Dustproof Screen Cover: Automatically lifts for quick tank cleaning, containing flying lime dust and cutting raw material waste.
Heavy-Duty Dual-Rear Axle Chassis Frame: Robust welded suspension fits mainstream heavy trucks, delivering strong traction on muddy, rough construction sites.
Wide Application Fields
1.Main highway cold regeneration and subgrade lime stabilization, the core application of this large-capacity lime material spreader.
2.Wide two-lane rural road reconstruction and farm field access hardening treatment.
3.Industrial park parking lots, campus playgrounds and logistics yard foundation lime paving.
4.Agricultural saline-alkali land improvement and large-area farmland soil conditioning.
Standard Factory Production Flow
1.Laser precision cutting of steel plates to eliminate dimensional errors for the tank, chain frame and suspension bracket.
2.Full penetration heavy welding for all load-bearing joints to prevent cabinet deformation under full-load operation.
3.Shot blasting rust removal, followed by double anti-rust primer and weather-resistant finish paint.
4.Assembly of hydraulic circuits, dual-chain drive system and cab intelligent control unit.
5.Pre-delivery full-load test: 2-hour continuous spreading test to calibrate discharge volume, chain stability and hydraulic lifting performance.
Real Global Customer Reviews
Overseas road contractors comment that the 14m³ lime spreader's large tank capacity cuts refilling frequency and raises daily construction output significantly. Municipal engineering dealers praise this lime spreading equipment's simple cab operation and stable even spreading effect, which meets strict highway base quality standards. Rural infrastructure clients note the 14 square self-propelled spreader passes narrow village curves smoothly via single-side discharge mode, with durable alloy teeth lowering long-term maintenance costs. Repeat bulk orders prove its reliable performance for large-scale overseas road projects.
Common Customer Fault Solutions
1.Lime spreading equipment outputs uneven lime thickness during full-load operation Solution: Reset cab quantitative spreading parameters; clear lime agglomerates jammed on dual chains; adjust hydraulic valve balance for consistent left-right discharge.
2.14m³ lime spreader hydraulic screen cover fails to lift Solution: Inspect hydraulic pipelines for oil leakage and air entrapment; refill dedicated hydraulic oil and adjust cover hinge tension springs.
3.Dual drive chains slip when the large-capacity lime material spreader works on gravel-rich subgrade Solution: Replace overstretched worn chain segments; calibrate chain tensioners to eliminate excessive sagging during high-load spreading.
4.Engineering lime paving vehicle alloy cutter teeth wear rapidly Solution: Slow truck travel speed to reduce impact overload; stock spare alloy cutter assemblies and regularly clear stone debris around the mixing roller.
