SPS125V versatile paver is developed by our company, which is suitable for paving highway base and surface. It absorbs advanced technology of foreign machine, high automation, easy operation and high efficiency make it ideal machine for the user.

The machine is of hydraulic driving and is equipped with mechanically pieced screed with vibrator and double tamper. SPS125V versatile paver can pave the road with good leveling and high density, and its vulnerable parts use advanced wearable material to make sure the performance.

Main Characteristic

1. Full hydraulic drive, controlled by microcomputer with digital display and fault diagnosis function.

2. Right and 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 probe, which reaches the demand of high-grade road smoothness. It controls in time, convenient and intuitionist. 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-sink age function.

6.Germanycentralized lubrication system.

7. All key parts are imported.

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

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. & right crawlers traveling devices        2. & right conveyors

3. & 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.

Steering

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

Hopper

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 controller and two batteries. The voltage is 24V.

Automatic Leveling Unit

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