Description of Chip Spreader
1. As a kind of road maintenance machinery, it combines technical, electrical, and hydraulic and aerodynamic technologies all in one machine;
2. It delivers easy operation, even spreading capacity and adjustable spreading width etc.
3. It is a patented product of our company, with equal performances to similar products aboard.
4. Cooperated with the asphalt distributor, it\'s an ideal engineering vehicle for chip sealing and chip transportation.
Main Technical Parameters of Chip Spreader

Equipment Components and Structural Features of Chip Spreader

It is composed of electrical system, hydraulic system, mechanical system, air supply system, water spraying system and operation system.

Electrical system
- Separately-controlled 16 discharge doors for flexible adjustment of spreading width.
- The hopper can be lifted and lowered in the driver\'s cab or on the console.
- Perfect lighting system for easy light construction.
- Hopper lifting limit alarm to enhance safety.
- Electrical connection between the automobile and the equipment adopts quick plug structure, easy for disassembling.

Hydraulic system
- Imported components go through strict detection and adjustment for the stability of system.
- System refitting achieves two different working modes: pre-disassemble and post-disassemble.
- Equipped with filter to keep the hydraulic oil clean, the system stable and durable.
- The refitted hydraulic circuit ensures that the hopper with heavy load could uniformly and stably descend.
- The hydraulic circuit connection between the vehicle and chip spreader adopts quick plug structure, easy for disassembly.

Mechanical system
- The fine tuning device installed can adjust single discharge door to effectively realize spreading evenness.
- Unique roller anti-slipping device solves the problem of stone skidding on the roller.
- Inclination angle of separating plate and discharge plate can be adjusted to fit for spreading stones of different specifications (S3—S24mm).
- The engineering equipment can be easily and reliably fixed, convenient for dismantling.

Air supply and water spraying system
- The air supply system is installed with device to filter water and foreign matter for reliability of the system.
- Superior elements for the stability and reliability of the air course.
- Tire water spraying device is equipped to prevent the tires and asphalt from bonding, ensuring good construction quality.
- Spraying system is equipped with device filtering foreign matter to avoid tube and nozzle choking.
Operation system
- It realizes integrated control of mechanical, electrical, hydraulic and air supply system, easy to operate.
- The angle of operating platform can be adjusted to be parallel with the ground to make sure safe and comfortable operation.

Technical requirements to the chassis

1. DC12×2 series power, negative ground
2. When the power takes off device working, rearward hopper can be lift, fall and stop at any position.
3. Volume of hydraulic oil tank: 60L
4. Outer size of discharge hopper: 2400±10mm
5. Inner size of discharge hopper: 2300±10mm
6. Hopper overhang L2: ≤850mm

Advantages
- Being cost effectively
- Imported key parts of hydraulic system for stable performance.
- Running stably and spreading uniformly. Single hopper door can be controlled separately to adjust the spreading width.
- Unique roller anti-slipping device can effectively solve the problem of stone skidding on the roller instead of being discharged in real operation.
