Luoyang, China – Luoyang Lutong Heavy Industry, a leading domestic manufacturer of road construction machinery, has upgraded its classic compaction equipment with the LTD723H 23-ton fully hydraulic dual-drive single drum vibratory roller. Tailored for highway, municipal, and large infrastructure projects, this new-generation roller integrates powerful power performance, precise compaction technology and extreme working condition adaptability, delivering efficient, stable and energy-saving compaction solutions for modern road construction.
Powered by a high-performance Weichai National III diesel engine with a rated power of 140kW, the LTD723H roller features a large power reserve coefficient and outstanding power stability. Different from ordinary construction machinery, this model is specially optimized for high-altitude environments, supporting stable and efficient operation at altitudes above 4,000 meters. Equipped with an integrated oil-water heat dissipation system, it effectively solves the heat dissipation challenges under high-load and high-altitude working conditions, ensuring long-duration continuous operation and greatly improving construction continuity in plateau and mountainous areas.
In terms of compaction performance, the LTD723H adopts an advanced full-hydraulic dual-drive system and a frequency-conversion and amplitude-adjustable vibration system, which is the core advantage of its high-quality compaction. The machine supports two amplitude modes of 1.9mm and 0.95mm, with a maximum excitation force of 410kN, forming a deeper compaction influence layer and realizing uniform and dense compaction on various road base materials such as sandy soil, gravel and asphalt mixture. The 2130mm wide vibrating drum and 3500mm wheelbase design expand the single-operation compaction area, effectively improving overall construction efficiency while ensuring flat road surface molding quality.
Focusing on operational flexibility and construction safety, the LTD723H is equipped with articulated steering and two-gear stepless speed regulation, enabling flexible steering and adjustable construction speed to meet the refined compaction requirements of different construction stages. The built-in power-off braking system ensures stable start and stop without roller marks on the road surface, avoiding secondary repair work and reducing construction costs. In addition, the humanized design further optimizes the operating experience: the streamlined body, arc-shaped windshield and flip-type cab provide operators with a wider field of vision and convenient daily maintenance, greatly reducing equipment maintenance time and labor costs.
With the booming development of global infrastructure construction, the demand for high-adaptability and high-efficiency road machinery is increasing. The Lutong LTD723H roller perfectly balances strong performance, fuel economy and environmental adaptability, breaking through the limitations of traditional rollers in high-altitude and complex working conditions. It has become a cost-effective core equipment for road base compaction, road renovation and municipal engineering construction.
Industry insiders said that the launch of the LTD723H further enriches Luoyang Lutong’s product matrix of medium and large compaction machinery. With reliable product quality and excellent on-site adaptability, this model will help domestic and foreign engineering projects improve construction quality and efficiency, and consolidate Lutong’s leading position in the global road construction machinery market.
