Technical Specifications
Drive System
The whole machine is driven mechanically-hydraulically. Flywheel end of engine is connected with transfer case. The front of engine is connected with split flow pumps to supply power to the components as follows:
1. crawler traveling devices
2. conveyor and screw feeder
3. tamper and vibrating device
4. hopper folded in & out, screed up & down and other cylinders action
Traveling Device
It is consisted of gear box, transfer case, traveling clutch and chain transmission.
The driven chain wheel activates the crawler.
Weight Bearing Mode
There are two crawlers. Crawler patches are configured with rubber. Each crawler ground touch area is 3050*300mm.
Steering
The traveling clutch is operated by hydraulic cylinder. The brake can make the machine turn at former place.
Hopper
The capacity is 12 tons and operated by hydraulic cylinder for entire discharge.
Push Roller
The roller can swing to push the truck rear wheels.
Conveyor
Left and right conveyor is independently driven. Clutch is controlled by hydraulic cylinder.
Feeder System
The system uses screw feeder which blades are of high wearable material and are easily replaced.
Electrical System
The system is equipped with two batteries. The voltage is 24V.CanopyIt is consisted of steel tube and cloth.
Automatic Leveling Sensors
It has two longitudinal and one transverse leveling units, used for automatic adjustment of slope and grade.

Main Performance
1. Solid and durable crawler’s device, which offers powerful tractionThrust wheel can be adjusted by floating unit and machine’s height to ensure driving smoothly, especially when paving on rough roadbed. Crawler traveling device is consisted of permanent lubricated thrust wheel and track shoes, which is durable, good adhesive and no easy slipping.
2. Independent left & right conveyor and screw feederIndependent operation for L/R conveyor and screw feeder, easy operation. Screw feeder is extended mechanically. Screw feeder blade is made of wearable material, convenient replacement to ensure screw life
3. Centralized Lubrication System
The system charges lubricating grease to all high temperature bearings automatically, which improves much the convey and feed reliability and reduces the failure rate maximally.
4. Auto Leveling Units to offer Reliability for Road Smoothness
The machine is equipped with two longitudinal and one transverse automatic leveling probes, which reaches the demand of high-grade road smoothness. It controls in time, convenient and intuitionistic. It can prevent the asphalt from valid filling to reduce construction cost.
5. Advanced ScreedScreed has vibration and double tamper to offer quality of pre-pressed compaction. One way mechanically extended screed has good stiffness. Screed bottom is made of advanced wearable material in the world.
6. Wide Eyeshot and Removable Operation PlatformAll the control elements centralize on operation platform for easy operation. Operation platform can be moved right and left that can reduce job of operator and improve efficiency to guarantee pavement quality.
7. Mixture conveying system with material controller
Discharge jumping-off point of is located in the head of conveying system which discharge the head of mixture out of hopper. Screw conveyor is equipped with material controller to control the height of material pile.
