The XS395IV fully hydraulic single-drum vibratory roller is a heavy-duty vibratory roller designed for the compaction of large-scale rock-fill embankments and extra-thick layers, while also being capable of handling standard layer compaction. It is the ideal compaction equipment for rock-fill dams, extra-thick stabilized soil layers, highway subbases, and road subgrades. Equipped with a high-power engine and featuring numerous adaptive designs specifically tailored for rock-fill dam compaction, this machine effectively meets the demands of dam construction.
The XS395IV stands at the apex of single drum roller technology. With an operating weight of 39.5 tonnes, it exerts ground pressure unmatched by lighter machines. The thick, abrasion-resistant drum and massive frame are designed to withstand the harshest conditions, from quarry floors to dam embankments.
Dual-frequency vibration with high amplitude penetrates deep lifts, achieving density in fewer passes. The intelligent compaction system provides real-time stiffness feedback, enabling precise control over layer quality. This machine dramatically cuts rework and accelerates project schedules.
Every structural component, from the articulated joint to the drum supports, has been fortified. Finite element analysis guided the reinforcement of high-stress zones. The result is a roller that thrives under continuous, heavy-duty cycles without fatigue or failure.
Equipped with Weichai National IV water-cooled engines, which offer high power output, low fuel consumption, and low noise levels.
A single-circuit, dual-motor closed-loop hydraulic drive system comprising an electronically controlled proportional valve, motors, and a long-life reduction gearbox provides full-wheel drive to the front and rear wheels. This ensures excellent traction and hill-climbing capability. The system operates at a constant speed within the set range, guaranteeing optimal working speed under various operating conditions. It also features an automatic anti-slip and self-rescue mode to minimize wheel slippage.
The domestically manufactured heavy-duty drive axle offers high load-bearing capacity and reliability, ensuring the roller can deliver maximum traction under various working conditions. Equipped with 20-inch stone-type tires, it is particularly suitable for stone compaction.
An electronically controlled closed-loop hydraulic system, comprising two-point variable-displacement and fixed-displacement motors, delivers a maximum power of 181 kW, effectively meeting the requirements for rock compaction.
Mega-dam projects rely on the XS395IV for core and filter compaction. Its deep penetration and high force densify rockfill lifts up to 1.3 meters, guaranteeing structural stability. The roller’s gradeability allows safe operation on sloped embankments where smaller machines would struggle.
Major highway construction demands the fastest possible base compaction. The XS395IV covers wide lanes with fewer passes, drastically cutting project duration. The intelligent monitoring documents density compliance, simplifying acceptance testing by state authorities.
Airport runway and taxiway projects require the ultimate foundation integrity. This roller produces uniform density to design depths, eliminating differential settlement risks. Data export provides a complete compaction record for aviation authority audits, protecting the contractor against future claims.
Heavy industrial and mining sites use the XS395IV for haul road construction and platform preparation. It compacts heavily loaded surfaces that must withstand ultra-class trucks. The machine’s robust frame and sealed bearings survive abrasive, dusty environments without premature wear.
The XS395IV is not just a larger roller; it’s a comprehensive compaction solution. Its hydrostatic drive eliminates clutch and transmission wear points common in mechanical machines. The closed-loop hydraulic system boosts reliability and lowers lifetime maintenance expenditure significantly.
Fuel efficiency is optimized through load-sensing hydraulics and auto-idle features. The engine provides massive torque at low RPM, reducing consumption under heavy load. Long service intervals for the vibration module and hydraulic system mean more hours on the job and fewer in the workshop.
Global XCMG support ensures parts and expertise are available wherever the machine operates. The XS395IV shares many components with the proven SIV series, simplifying fleet management. It represents a safe, high-return investment for contractors tackling the world’s largest earthworks.
Ground-level service points simplify daily inspections. The engine compartment tilts open hydraulically for unrestricted access to filters and belts. Sight gauges for hydraulic and fuel tanks eliminate guesswork. All routine checks can be completed in under ten minutes.
The vibration exciter is self-contained with a dedicated lubrication circuit. Oil changes require no drum disassembly. Centralized grease banks for articulation and steering joints ensure thorough lubrication with minimal effort, reducing the risk of pin failure.
Advanced onboard diagnostics track engine hours, filter life, and hydraulic condition. The system alerts the operator before a minor issue escalates. This predictive approach extends component life and avoids unplanned downtime on critical-path earthwork activities.
Operator protection is paramount. The certified ROPS/FOPS cab withstands heavy impact. Emergency stops at the panel and ground level immediately disable all machine functions. The parking brake engages automatically on engine shutdown or hydraulic pressure loss.
Full-perimeter LED lighting and 360-degree camera coverage eliminate blind spots. An audible reverse alarm and optional object detection system warn nearby personnel. These features make the XS395IV safe to operate on congested, round-the-clock project sites.
The engine meets stringent emission standards via advanced combustion and aftertreatment. Eco-mode limits fuel burn during light-load travel without affecting compaction power. Biodegradable hydraulic fluid options are available for environmentally sensitive watershed and coastal projects.
All fluid reservoirs are double-sealed and equipped with spill-free couplings. The belly pan contains accidental drips. By minimizing its environmental footprint, the XS395IV helps contractors meet sustainability goals while maintaining extreme productivity.
The XCMG XS395IV single drum roller redefines heavy compaction. Its incredible weight, force, and intelligent systems deliver density certainty on projects where failure is not an option. Every detail, from the hydrostatic drive to the operator’s seat, is optimized for performance.
Contractors worldwide trust the XS395IV to build foundations that last for generations. It accelerates work, reduces rework, and documents quality. For the most demanding earthworks, this 39.5-ton giant is the clear choice to keep your project on solid ground.
