Zoomlion ZTC250V431

The Zoomlion ZTC250V431 is a high-performance 25-ton truck-mounted hydraulic crane, designed to deliver superior lifting capacity, precise control, and optimal efficiency. It features a four-section U-shaped boom, with a telescoping range from 10.7 meters to 35 meters, ensuring strong load-bearing capacity and reduced deflection. Additionally, the 8-meter jib, with offset angles of 0°, 15°, and 30°, allows for enhanced operational flexibility, providing a maximum lifting height of 43 meters.

This crane is powered by a WEICHAI WP7 diesel engine, generating 176 kW of power and 1,000 N·m of torque, ensuring strong and reliable performance. The FAST mechanical gearbox features eight forward gears and two reverse gears, delivering smooth and efficient power transmission. With a maximum driving speed of 90 km/h and a gradeability of 42%, the ZTC250V431 is well-suited for transport across different job sites. The minimum turning diameter of ≤20 meters provides excellent maneuverability, even in confined spaces.

For lifting operations, the ZTC250V431 is equipped with a high-performance hoisting system, featuring dual winches with a hoist rope speed of 135 m/min (main winch) and 135 m/min (auxiliary winch). The boom derricking time is 25 seconds, while boom telescoping takes 45 seconds, allowing for quick setup and efficient operation. The load-sensing slewing system, with a slewing speed of 0-2.7 rpm, ensures precise load positioning and smooth crane rotation.

To enhance stability, the H-type outrigger system offers a fully extended transversal span of 6.2 meters and an intermediate extension of 4.25 meters, ensuring a solid foundation for lifting tasks. The chassis is built from high-strength steel, designed for durability and heavy-duty operation. The front axle leaf spring suspension and rear rubber suspension with thrust rods and balanced beams further improve ride comfort and load distribution.

Operator comfort and safety are key design priorities in the ZTC250V431. The cab is designed for ergonomic efficiency, featuring air conditioning, a tiltable operator seat, and a full-view layout for better visibility and reduced fatigue. The electrical system (DC 24V) with CAN BUS technology enhances control precision and monitoring capabilities. Safety features include a load moment indicator (LMI), relief valves, hydraulic locks, and emergency stop functions, ensuring secure and reliable operation.

With its strong lifting capabilities, intelligent control systems, durable chassis, and energy-efficient design, the Zoomlion ZTC250V431 is an excellent solution for medium-duty lifting applications in construction, infrastructure, and industrial projects.
