Zoomlion ZTC350H552

The Zoomlion ZTC350H552 is a high-performance 35-ton truck-mounted hydraulic crane, engineered for reliable lifting, efficient transport, and intelligent operation. The crane features a five-section U-shaped main boom, constructed from high-tensile steel, extending from 11.2 meters to 44 meters, providing enhanced structural stability and reduced deflection. Additionally, it includes a two-section jib (9.5m and 16m) with adjustable offsets of 0°, 15°, and 30°, allowing for greater reach and operational flexibility. The maximum lifting height reaches 60 meters, making it ideal for a variety of lifting tasks.

Powered by a WEICHAI WP10H350 diesel engine, the ZTC350H552 delivers 228 kW of power at 1900 rpm, ensuring strong and reliable performance. The FAST mechanical gearbox provides smooth gear shifting, allowing for efficient power transmission. With a maximum driving speed of 85 km/h and a gradeability of 43%, the crane offers excellent mobility and the ability to navigate different terrains. The minimum turning diameter of 24 meters allows for better maneuverability, even in restricted spaces.

For lifting operations, the ZTC350H552 is equipped with a high-performance hoisting system, featuring dual winches with a main hoist rope speed of 135 m/min and an auxiliary hoist rope speed of 120 m/min, ensuring fast and precise lifting. The boom derricking time is 45 seconds, and boom telescoping takes 95 seconds, allowing for rapid setup and operation. The load-sensing slewing system, with a slewing speed of 0-2.2 rpm, ensures smooth rotation and precise load positioning.

The crane’s stability is enhanced by a two-stage H-type outrigger system, providing a fully extended transversal width of 7.3 meters and an intermediate extension width of 4.8 meters, ensuring secure lifting support. The chassis is constructed from high-strength steel, built to withstand heavy-duty operations. The front axle leaf spring suspension and rear rubber suspension with V-shaped thrust rods improve load distribution and ride comfort.

Operator comfort and safety are key priorities in the ZTC350H552. The spacious cab is ergonomically designed, featuring climate control (AC and heater), an adjustable seat, and a modern control interface for better visibility and ease of operation. The electrical system (DC 24V) with CAN BUS technology enhances control precision and system monitoring. Safety features include a load moment indicator (LMI), relief valves, hydraulic locks, and emergency stop functions, ensuring secure and stable operation.
