Product Introduction
The 12 sided traction type spreading vehicle, also known as the 12 square ash truck, is a large-capacity tractor-towed construction implement categorized as professional road construction powder spreader and heavy engineering towed spreader. Designed as an export-type towed spreader optimized for overseas highway projects, it acts as a high-efficiency highway base powder spreader for large-area subgrade stabilization work. Matched with tractors above 120 horsepower, this machine adopts an oscillating screen hydraulic discharge system to evenly distribute cement, quicklime and hydrated lime powder, solving the low-efficiency drawbacks of small-volume spreaders on wide highway construction sections. It supports standardized export packaging and customized structural adjustments to fit regional road construction standards across global markets.
Material & Structural Specification
Thickened Carbon Steel Storage Tank: The 12-cubic large hopper uses high-strength carbon steel plate with anti-corrosion spray coating, resisting dry powder corrosion and long-distance transportation wear.
Hydraulic Oscillating Screen Spreading Assembly: Heavy-duty vibrating screen breaks powder agglomerates to guarantee consistent spreading thickness, with independent hydraulic oil circuit for speed adjustment.
Heavy Engineering Wide Tires: Oversized anti-sink construction tires adapt to muddy, gravel and uneven rural construction sites, effectively avoiding vehicle sinking during full-load operation.
Reinforced Traction Suspension Frame: Welded thick steel traction bracket fits mainstream global tractor three-point hitch structures, stable for long-distance towing transit.
Fully Enclosed Dustproof Cover: Optional dust shielding cover reduces powder flying loss, cutting raw material waste and lowering on-site dust pollution.
Wide Application Fields
1.Main Highway Base Construction: Large-scale two-ash gravel and cement stabilized soil spreading, the core application of this highway base powder spreader.
2.Rural Wide Road Reconstruction: Two-lane village road subgrade lime powder paving and farm field passage hardening treatment.
3.Old Pavement Cold Regeneration: Even distribution of cement and lime stabilizer during aged asphalt pavement crushing and mixing renovation.
4.Industrial & Campus Ground Works: Factory parking lots, campus playgrounds and logistics yard foundation dry powder spreading.
5.Overseas Export Road Projects: As a dedicated export-type towed spreader, it adapts to rough construction environments in Africa, Southeast Asia and other regions.

FAQ
1.What tractor horsepower is required to pull this 12 sided traction type spreading vehicle ?
A: Tractors with 120 HP and above are recommended to ensure stable towing under full 12-cubic powder load.
2.Can this road construction powder spreader adjust spreading thickness freely?
A: Yes, operators control discharge volume via the hydraulic valve in the tractor cab to adjust spreading thickness from thin to thick.
3.Is this engineering towed spreader suitable for long-distance export transportation?
A: Absolutely. It is built as an export-type towed spreader with reinforced frame and export-specific shockproof packaging.
4.How to handle powder blockage on the oscillating screen during daily work?
A: Stop the tractor, cut off hydraulic power and clear caked lime or cement powder from the screen surface before restarting.
5.Can the highway base powder spreader work normally on muddy rural subgrade?
A: Its wide heavy-duty anti-sink tires greatly reduce sinking risk; slow down travel speed when operating on extremely soft mud ground.
