Product selling points

The miniaturization of the machine and the width of the 1.8m ultra-small machine can meet the construction work of urban communities and roadways.

It adopts hydraulic drive, stepless speed change, high degree of automation, flexible operation and simple and convenient operation.

It is equipped with Shangchai water-cooled turbocharged diesel engine (73.5kW / 2000rpm), with sufficient power reserve, good diesel atomization, good economy, low noise, long life and wide application range.

The hydraulic system uses load-sensitive control technology to make the power output efficient and energy-saving. The driving components are imported from Germany Rexroth to ensure system reliability.

The 12t hopper is designed to be large enough to always store enough material. The receiving interface can adapt to different tonnage carts.

The hoppers on both sides can be folded separately, and the swing-type follow-up pusher ensures stable discharge during asymmetric paving. Ensures proper paving along obstacles such as walls.

The traveling system adopts hydraulic bridge drive transmission, stepless speed change, high degree of automation, flexible maneuvering, and simple and convenient operation. The drive axle adopts XCMG's proprietary technology with automatic differential speed.

The transmission and distribution system is driven by an open hydraulic system consisting of a load-sensing pump, a load-sensing multi-way valve and a cycloidal motor. A single plunger pump is used for transmission and distribution. The left and right independent motors are directly driven. The motor and the actuator are driven by a chain. The conveying scraper adopts a double chain structure, which is driven independently from the left and right, and can be reversed. The miniaturized design of the material distribution system, the new compactness of the left and right independent drive of the material distribution box, and the unique "integrated" blade shaft greatly improve the convenience of the small paver.

The automatic leveling device can accurately control the paving thickness and slope, so that the longitudinal flatness reaches 3mm / 3m and the lateral slope is within 0.02%, which meets the requirements of high-grade highways.

The innovatively designed E340 small hydraulic telescopic screed uses a three-point suspension structure and a single-vibration compaction device, which improves construction stability and pavement forming quality.

The whole machine has the advantages of high degree of automation, simple and convenient operation, good construction quality and high operating efficiency.
