Luoyang, China – Luoyang Lutong Heavy Industry Machinery, a leading domestic manufacturer of road construction equipment, has unveiled its high-performance LTD720H full-hydraulic dual-drive single drum vibratory roller, a 20-ton grade compaction machine tailored for modern highway, municipal road, and large-scale infrastructure construction. Integrating optimized power configuration, intelligent vibration technology and reliable structural design, the LTD720H roller sets a new benchmark for efficient and durable road compaction in complex working conditions.
As a core model in Lutong’s medium and large compaction equipment lineup, the LTD720H roller features a standard operating weight of 20,000kg, delivering stable and powerful compaction capacity for various road base and surface layers. Equipped with a high-efficiency WP6G190 diesel engine that meets national stage III emission standards, the machine achieves a rated power of 140kW with abundant power reserve. Notably, the power system is professionally optimized to adapt to high-altitude environments above 4,000 meters, ensuring stable output and consistent construction efficiency in plateau and mountainous areas where ordinary construction machinery often struggles to operate properly.
The equipment adopts a mature full-hydraulic dual-drive system, equipped with world-class brand hydraulic pumps and motors, which guarantees outstanding transmission efficiency and long-term operational stability. Different from single-drive rollers, the full dual-drive design provides stronger traction and gradeability, effectively solving slipping and insufficient compaction problems on soft foundations, steep slopes and uneven road surfaces. Meanwhile, it supports stepless speed regulation in two gears and articulated steering, enabling flexible operation and precise control, greatly reducing the operation difficulty for drivers and improving construction precision.
In terms of compaction performance, the LTD720H is fitted with a advanced frequency conversion and amplitude conversion vibration system, with dual vibration frequencies of 28Hz and 35Hz and matched adjustable excitation force. The dual-mode vibration design allows construction personnel to switch parameters freely according to different construction materials and process requirements, realizing high-density compaction of soil, gravel, asphalt and other pavement materials. It effectively improves pavement flatness and compaction uniformity, laying a solid foundation for road durability and driving safety.
Safety and humanized design are also highlights of the LTD720H roller. The machine is equipped with a reliable power-off braking system, which can realize stable braking in various working states to avoid construction safety hazards. The optimized body structure and shock-absorbing cab greatly reduce vibration and noise during operation, improving driver comfort and long-hour working adaptability. In addition, the equipment supports optional auxiliary configurations such as detachable padfoot drums and intelligent compaction management systems, which can meet the personalized construction needs of earth-rock filling, special road foundation reinforcement and other complex projects.
With the booming development of global infrastructure construction, high-efficiency, energy-saving and multi-scenario adaptable road machinery has become the mainstream demand of the market. The Lutong LTD720H roller perfectly balances powerful performance, environmental protection, energy saving and operational flexibility, covering municipal road construction, highway reconstruction, airport and port foundation treatment, water conservancy project filling and other diverse application scenarios.
Industry insiders said that the launch of the LTD720H further enriches Lutong’s product matrix of medium and large compaction equipment. With its superior high-altitude adaptability, stable hydraulic drive system and cost-effective performance advantages, the model will effectively help domestic and foreign engineering enterprises reduce construction costs and improve project quality, and enhance the market competitiveness of Chinese-made road construction machinery in the global infrastructure field.
