Asphalt Chip Sealer DAL08-T35

Asphalt Chip Sealer DAL08-T35
Synchronous Chip Sealer DAL08-T35, which is a type of special-purpose machinery jointly developed and manufactured for construction of bitumen pavement by the Company, USA Phoenix, and Chang An University, is widely applicable to the quick synchronous highway spray/distribution operations, and it may spray/distribute bitumen and aggregate as per synchronous or separate mode. It is provided with the advantages of costing saving, surface wear resistance, slip resistance, water resistance, and quick traffic recovery when construction is completed. It is applicable to the construction of highways of different grades. 
The vehicle is based on the modified chassis SX1255JM434 manufactured by Shaanxi Automobile Group, with reliable quality. Its bitumen tank is cased with heat insulating material aluminum silicate, with relatively heat preservation performance. Automatic asphalt spraying as per preset volume through the rear spray pipe or manual asphalt spraying through the portable spray pipe can be freely selected. The external asphalt pump allows easy maintenance. The pipeline system allows heat-transfer oil heating and high-pressure air scour, so they may be free of clogging. The chip distributing mechanism is designed with good compactness, and the opening extent of the material gate may be controlled through the manual rotor disc. The spray/distribution volume/accuracy of bitumen and chip is under overall computerized control such that the synchronous interlock of bitumen/chip spray/distribution may be uniform and zero-vacancy spray/distribution. Furthermore, the vehicle is characterized by elegant appearance, compact construction, comfortable driving, and convenience in operation etc., and it is particularly applicable to the construction, repair, and maintenance of highway pavement.

Performance Feature

Delong chassis SX1255JM434, which is manufactured by Shaanxi Automobile Group and characterized by its reliable quality, is applied to support the vehicle body and offer motive force. 
2、Asphalt Tank 
It is cased with heat insulating material aluminum silicate with relatively heat preservation performance, and its stainless-steel casing is pleasing to the eye, ensuring high neatness. 
3、Storage Bin System 
The vehicle is provided with a fixed storage bin and a mobile storage bin with high capacity, and the upward/downward motions of the latter are under computerized control. The 2-segment construction of a lift-up bin + a fixed bin may effectively expand the capacity of the bins and their working hours. 
4、Bitumen Spray System 
The ON/OFF of each spray nozzle is controlled by a single cylinder, and the speed of bitumen pump may be automatically regulated through the automatic control system as per the spray volume. 
5、Bitumen Circulating System 
The hydraulic motor drives the bitumen pump such that the high/low circulation of bitumen may be realized in the bitumen tank, bitumen pipeline, and the rear spray mechanism. 
6、Chip Distribution System 
In accordance with different distribution mode, the opening extent of the aggregate gate may be regulated manually so as to realize the optimum, flexible, and uniform distribution. 
7、Hydraulic System 
It may drive hydraulic motor to fulfill various actions, ensuring high working efficiency. 
8、Heat Transfer Oil Circulating System 
The hydraulic motor may drive the heat transfer oil pump to keep warm or heat up the bitumen tank, bitumen pipeline, and spray system. 
9、Pipeline Purging 
Heat transfer oil heating and high pressure air purging are applied such that the spray nozzles are seldom jammed, and the heating and purging may be automatically fulfilled by the electric system, with high reliability and expedience.
