Product Deep Dive

As an established loader manufacturer with 24 years of industry expertise, Zhengtai designs the ZT821-LG5 landfill compactor specifically for the harsh operating environment of waste disposal sites. This machine solves the core pain points of landfill operators: low compaction efficiency, high failure rate in dusty and corrosive conditions, and elevated long-term operating costs. Each unit undergoes strict factory load testing and full performance inspection before delivery, ensuring stable performance even under 16-hour continuous working schedules.

Powered by a genuine WEICHAI WD10G220E23 engine with 162kW rated power, this heavy compactor delivers strong power output and excellent fuel economy. As a standard product in our Chinese construction machinery export portfolio, the Weichai engine enjoys global after-sales support and wide availability of heavy equipment components, which drastically cuts downtime for overseas customers. For high-altitude regions above 3000m, we also provide optional high-altitude adjusted engine configurations to guarantee consistent power performance.

The full hydraulic steering system with central articulated structure enables ±40° steering angle and ±15° lateral frame swing, allowing the machine to adapt to undulating landfill surfaces while keeping all four wheels grounded. The 280mm ground clearance and 4-wheel drive transmission ensure smooth passage over accumulated waste piles and muddy access roads. With a 6085mm outer turning radius, operators can work efficiently in narrow landfill cells without repeated repositioning, significantly improving daily compaction output.

We offer factory price direct supply for global distributors, waste management companies and engineering contractors. Each 21-ton landfill compactor is packaged according to a standard 40HQ container loading plan to minimize international shipping costs. For bulk orders, we support custom configuration including wet brake axles, different emission stage engines and optional cabin accessories. All products are ISO 9001 certified and comply with international heavy machinery manufacturing standards.

Beyond standard landfill compaction work, this machine is also suitable for waste recycling stations, transfer stations and large-scale construction waste disposal sites. The front pushing shovel can be used for waste leveling, stacking and site cleaning, realizing multi-functionality of a single unit and reducing customers' overall equipment investment costs.
