1. It adopts Shan M300 chassis with276KW/375HP engine which has strong power for good construction performance.b)Auxiliary engine 73.6kw,realize the heating when traveling to shorten the operation time and improve the working efficiency.;
2. this hi-tech equipment is able to combine the systems of asphalt binder spray, fiber spray and aggregates spreading into one entire process
3. It is no need of lifting the hopper to spread aggregates,which realizes operation in height-limit condition,such as bridges and culverts.;
4. It is completely controlled by electrical system of high-level automation. The spreader’s expansion and spray bar width can be flexibly controlled automatically. It can accurately calculate the asphalt spray volume in construction;
5. Double-screw charger conveys aggregates to the discharging unit of 4000mm wide, then aggregates fall down by roller friction and self gravity over distribution plate to keep uniform spreading effects;
6. It reduces the work intensity of construction, saves labor power, decreases the construction costs and improves working efficiency and quality
7 The whole machine runs stably and makes uniform spray and spreading , It can flexibly regulate asphalt spray width, fiber spray width and aggregates spreading width.
8 Sound and durable corrosion-resistant insulation layer keeps heat preservation index no more than 12℃/8h.
9 The tank has two imported diesel burners with high efficiency ,fast heat-up speed(≥20℃/h) ,auto ignition and temperature control system, stable and safe performance.
10 It can spray various kinds of asphalt and spread aggregates of sizes from 3mm to 25mm
11 Spray bar is foldable, and it clearance to ground is able to be regulated; fiber spray unit is able to swing horizontally .
12 Precisely processed nozzles ensure spray uniformity of each nozzle and the spray effects
13 It adopts JOHNSON asphalt pump and heat oil pump.They are with good performance,large range of rotation,good sealability and stable flow.
14 Humanized operations of remote control and site operation provide great convenience to the operato.
15 Perfect combination of electrical control and constant pressure device of hydraulic system makes spray start as soon as the truck starts
The The burner dry burning-resistant safety device and heat conduction oil temperature monitoring system are first developed. The heating is safer and more reliable.
