Zoomlion ZTC550R532

The Zoomlion ZTC550R532 is a powerful and versatile 55-ton truck-mounted hydraulic crane, designed for heavy-duty lifting with precision and efficiency. The crane features a five-section U-shaped telescopic boom, made of high-tensile steel, extending from 11.2 meters to 44 meters, ensuring superior bending resistance and load stability. Additionally, it includes a two-section jib (9.5m and 16m) with adjustable offsets of 0°, 15°, and 30°, allowing for greater operational flexibility. The maximum lifting height is 60 meters, making it suitable for various lifting scenarios.

Powered by a WEICHAI WP10.336 diesel engine, the ZTC550R532 delivers 247 kW of power and 1,300 N·m of torque, ensuring strong performance under demanding conditions. The FAST mechanical gearbox offers eight forward gears and one reverse gear, providing efficient power transmission and smooth operation. With a maximum driving speed of 74 km/h and a gradeability of 40%, the crane is designed for quick transportation between job sites. The minimum turning diameter of ≤24 meters allows for better maneuverability, even in tight spaces.

For lifting efficiency, the ZTC550R532 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 ZTC550R532. 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.

With its excellent lifting performance, intelligent control features, durable chassis, and energy-efficient operation, the Zoomlion ZTC550R532 is a top choice for demanding lifting applications in construction, infrastructure, and industrial projects.
