Largest Zero Tail Swing Excavator
Maximum Heavy-Duty Output in Confined Spaces: Engineered to deliver the massive breakout force and digging depth of a large-class machine while maintaining a tail swing radius that stays within the width of the tracks, allowing for heavy-duty excavation in restricted urban sites.
Enhanced Operational Safety on Major Projects: Eliminates the risk of rear-end collisions with site barriers, passing traffic, or existing infrastructure. This allows operators on large-scale utility or roadwork projects to focus entirely on deep trenching without a secondary spotter for rear clearance.
Superior Lifting Stability and Capacity: Built with a heavy-duty, widened undercarriage and a reinforced X-frame chassis to compensate for the shortened rear, ensuring excellent lateral stability when handling large pipes, concrete barriers, or heavy attachments.
High-Torque Industrial Powertrain: Features premium, high-displacement diesel engines that provide the sustained torque required for continuous, high-intensity digging in compacted soil and rock while meeting international emission standards.
Advanced Load-Sensing Hydraulics: Equipped with high-capacity variable displacement pumps that ensure smooth, simultaneous multi-function operation, providing surgical precision for finishing work alongside massive power for primary excavation.
Spacious Ergonomic "Command Center" Cab: Despite the compact rear design, the operator station features a full-sized, ROPS/FOPS certified cabin with panoramic visibility, high-output climate control, and air-suspension seating to maintain productivity during long shifts.
Versatile Large-Scale Attachment Integration: Comes factory-fitted with high-flow dual-way auxiliary hydraulic lines, making it an ideal platform for heavy-duty attachments such as large hydraulic breakers, high-torque augers, and demolition grapples.
Rugged Structural Integrity: Constructed with high-tensile, robotically welded steel and reinforced stress points on the boom, arm, and chassis to ensure long-term reliability and minimal maintenance under rigorous commercial use.
Simplified Service Architecture: Designed with large-opening side and rear service hoods, providing total ground-level access to the engine, cooling system, and hydraulic pump for rapid daily checks and reduced service downtime.
Exceptional Project ROI: Provides the production capabilities of a heavy excavator with the accessibility of a compact unit, allowing contractors to complete large-scale projects in confined areas that would otherwise require expensive manual labor or smaller, slower machinery.
Professional Large-Capacity Zero Tail Swing Excavator: Heavy-Duty Power, Compact Rotation
Product Overview
Our Large-Capacity Zero Tail Swing (ZTS) Excavator series redefines the limits of compact engineering. Designed for contractors who require substantial breakout force and lifting capacity without the footprint of a traditional counterweight, these excavators are the premier choice for demanding urban infrastructure and high-traffic construction projects.
As a premier manufacturer, we have engineered these large-tonnage ZTS units to maintain perfect balance and structural rigidity during heavy-duty excavation. By eliminating rear overhang, these machines provide professional-grade efficiency while ensuring the safety of personnel and property on congested jobsites.

Key Features & Benefits
Powerful Zero-Swing Performance: Unlike standard large excavators that require significant rear clearance, our large ZTS models rotate entirely within the width of the tracks. This allows for high-capacity digging in traffic-restricted areas, narrow bridge sites, and dense urban environments.
Heavy-Duty Powertrain: Equipped with high-torque industrial engines from Cummins or Yanmar, these machines deliver the sustained power needed for deep trenching, rock breaking, and bulk earthmoving, all while meeting EPA Tier 4 Final and Euro Stage V emissions standards.
Intelligent Hydraulic Management: Our high-flow load-sensing system automatically adjusts hydraulic pressure and oil flow to match the specific workload. This ensures smooth, powerful multi-function operation, enabling the simultaneous use of boom, arm, and swing movements without power loss.
Reinforced Structural Integrity: Constructed with heavy-duty manganese steel and reinforced boom geometry, these units are designed for extreme torsional resistance. The X-frame chassis and wide-stance track rollers provide the high stability required for heavy lifting and high-reach excavation.
Premium Operator Comfort: The large-volume, pressurized cabin is designed for long shifts. Features include an ergonomic suspension seat, vibration-dampening mounts, and low-effort hydraulic pilot controls, ensuring the operator remains productive throughout the entire workday.
Applications
The large-scale Zero Tail Swing excavator is engineered for demanding industrial tasks:
Urban Infrastructure: Deep trenching for large-diameter water, sewer, and utility lines in metropolitan streets.
Road & Bridge Construction: Maintenance of bridge piers and highway embankments where lane closures are strictly regulated.
Heavy-Duty Demolition: Breaking up thick concrete foundations and steel-reinforced structures where maneuverability is essential.
Bulk Material Handling: Efficient loading of large-capacity dump trucks in tight site logistics.
Frequently Asked Questions (FAQ)
Why choose a Zero Tail Swing design for a large-tonnage excavator?
The primary benefit is efficiency and safety. In high-traffic environments, a standard-tail excavator may require blocking off multiple lanes or risking collisions. A large ZTS excavator completes the same heavy-duty work within a single lane, significantly reducing traffic management costs and project downtime.
Does a large ZTS excavator sacrifice stability compared to a standard-tail model?
No. We have utilized an optimized center of gravity and a heavier, reinforced undercarriage to ensure that our ZTS excavators provide the same, if not better, lifting capacity and stability as traditional excavators of the same tonnage.
Are these large-scale ZTS units compatible with heavy attachments?
Absolutely. The high-flow auxiliary hydraulic circuit is designed to power high-demand tools, including large-capacity hydraulic breakers, heavy-duty thumbs, and forestry mulchers, providing the versatility required for multi-phase projects.
