Driving/Riding Environment
* The mechanical drive system with three-speed regulation and flexible steering adapts to diversified working conditions.
*The installed Plate integral transmission features compact structure, small overall dimensions, stable gearshift, low impact, noise, and heat, and long life and is equipped with synchronizers to realize gearshifts during driving and guarantee handy operations and high efficiency.
* The excellent overall airtightness of cab and the three-stage shock-absorption for whole machine achieve low vibration and noise and the seat position and backrest angle are adjustable in large range to guarantee high operating comfort.
* The ergonomic cab features large space and excellent visual field.
* The safety passageway system and the reasonably arranged safety handrails and anti-skid footplates for whole vehicle guarantee the driver's safety.

Working performance
* The closed-loop hydraulic vibrating system is applied. With double-amplitude, its scientifically reasonable static linear load and exciting force configuration guarantees the effective compacting for the materials of diversified types and the pavements of diversified thicknesses.
* The imported heavy-duty variable displacement plunger pump is applied for the vibrating pump and the vibrating system is electronically controlled to realize simple operations and guarantee the reliability and flexibility of vibrating system.
* The vibrating drum adopts the new structure of Shantui's proprietary technology to thoroughly solve the oil leakage/permeation problem of vibrating drum and achieve high eccentric mass, high exciting force, and high static linear pressure of vibrating drum.
* The optional padfoot vibrating drum can be installed to expand the application scope of product and bring about value-added return of "One machine for two applications" for the user.

High maintenance convenience
* The hood of large opening angle eases the maintenances of engine and hydraulic system.
* The modular structure eases the disassembling of parts and ensures low maintenance cost and easy maintainability.
* Less malfunctions and convenient maintenances.

Operating cost
* The structural parts inherit the excellent quality of Shantui mature products to realize high durability.
* The core electric and hydraulic parts adopt imported products, featuring stable and reliable quality and extremely high reliability.
* This product is powered by SDEC SC8D185.2G2B1 turbocharged and intercooled engine, featuring excellent fuel economy, really high market ownership volume, strong parts universality, and low maintenance cost.
