    Technical Specifications

    Driving System

    The whole machine is hydraulically driven, the engine is connected with gearbox to  drive all the hydraulic pumps, which supply power to the components as follows:

    1. left & right crawlers traveling devices        2. left & right conveyors

    3. left & right feeders     4. double tamper     5. vibrating devices

    6. hopper folded in & out, screed up & down, screed extension & withdrawal, pivot cylinder

    Traveling Device

    Crawlers at both sides are hydraulically driven independently, controlled by microcomputer. It is consisted of variable motor and planet speed reducer of big ratio, which are connected with each other as a whole and installed in the drive hub.

    Weight Bearing Mode

    Each crawler has ten bearing wheels of free lubrication, which use power accumulator for tension. The rubber patches are replaceable. Each crawler touch area is 3247*320mm.

    Brake of Parking 

    Hydraulic normal close disc brake is installed in each traveling planet speed reducer respectively.


    Left & right crawler driving wheels speed is changed through turning potentiometer knob left or right to realize steering.


    The capacity is 14 tons. Hopper folded in & out is operated by hydraulic stroke cylinder for entire discharge.

    Push Roller

    The roller can swing to push the truck rear wheels.

    Conveyor System

    Scraper is used to convey material. Conveyor soleplate is made of imported wearable steel plate.

    Transmission: There is respective hydraulic driving system for each scrape conveyor, which is composed of pump, motor, speed reducer and chain transmission. The driven chain wheel runs the scraper.

    Operation speed: 0—29m/min. Manual operation can be realized through the switches on the operations console. Auto-operation is realized directly by supersonic material sensor.

    Feeder System   

    The system uses screw feeder which blades are of high wearable material and are easily replaced.

    Transmission: There is respective closed hydraulic driving system for each screw feeder, which is composed of variable displacement pump, motor, speed reducer and chain transmission. The driven chain wheel runs the screw.

    Operation speed: 0—100r/min, three—step speed change can be realized through the switches on the operations console. Auto-operation is realized directly by supersonic material sensor.

    Electric System

    The system is equipped with PLC2038 (Finland, EPEC company)

    Automatic Leveling Unit

    There are two longitudinal and one transverse automatic leveling units for adjusting longitudinal and transverse level automatically.

    Working Devices

    One way mechanical extended screed, heated by gas, screed soleplate made of imported wearable steel plate.

    Main Characteristic       

    1. Full hydraulic Drive, controlled by Microcomputer with Digital Display and Fault Diagnosis Function.

    2. Right and Left Hand Conveyors and Feeders are controlled by Ultrasonic Material Sensors to make sure automatic and even feed of material.

    3. Auto Leveling Unit 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.

    4. High Intensity Screed with Double Tamper and Vibrating Device to ensure ideal paving efficiency.

    5. Screed Anti-sinkage Function.

    6. Germany Centralized Lubrication System.

    7. All Key Parts are Imported.

    8. Humanization design has improved comfortable operation for the driver.

    Key Parts

    1. Engine: China engine(made in Shanghai)

    2. Pump and Motor: USA SAUER-DANFOSS and Germany Bosch-REXROTH

    3. Microprocessor: PLC2038, Finland

    4. Switches & Fitting: Germany
