Zoomlion ZRT400V432 Load Chart PDF + Specifications

The Zoomlion ZRT400V432 was developed as a compact rough terrain crane focused on balancing lifting performance, mobility, and operational simplicity. Positioned in the 40-ton capacity segment, the crane is intended for industrial maintenance, oil and gas projects, building construction, plant shutdown work, and general lifting operations where compact dimensions and strong terrain capability are essential.

The crane is equipped with a four-section telescopic boom manufactured from high-strength steel using a U-shaped boom profile for improved rigidity and optimized structural weight. The main boom extends hydraulically from 10 meters to 33 meters and incorporates synchronized telescoping systems for smooth extension and retraction. The boom head is equipped with four sheaves for efficient reeving arrangements and quick hook block configuration changes. Boom elevation ranges from -2° to 80°, enabling both low-angle and high-angle lifting operations. Full boom extension takes approximately 50 seconds, while boom raising and lowering requires around 45 seconds and 60 seconds respectively.

For increased lifting height and working range, the crane can be fitted with a two-section lattice swing-away jib. The jib length varies from 8 meters to 14 meters and supports offset positions of 0°, 15°, and 30°. The jib is side-mounted and can be stowed alongside the boom during transportation. With the jib installed, the crane achieves a maximum lifting height of approximately 47.8 meters, while maximum lifting height on the main boom alone reaches approximately 34.8 meters.

The ZRT400V432 has a maximum rated lifting capacity of 40 tonnes at a 2.5-meter working radius and develops a maximum lifting moment of approximately 136 tonne-meters. The crane maintains useful lifting capacities throughout the boom range and can operate with outriggers fully extended, intermediate, or fully retracted depending on site conditions. Lifting charts shown in the specification manual illustrate the crane’s adaptability in restricted jobsite environments where full outrigger deployment may not be possible.

The hoisting system utilizes hydraulic main and auxiliary winches mounted on the front section of the upper structure. The main winch stores approximately 130 meters of wire rope while the auxiliary winch carries around 110 meters. Maximum single-line hoisting speed reaches approximately 145 meters per minute, and maximum line pull is rated at about 5,500 kg. Hook equipment includes a 40-ton four-sheave main hook block and a 4.5-ton auxiliary hook.

Power is supplied by a Cummins QSB6.7 six-cylinder turbocharged diesel engine producing 129 kW at 2,200 rpm with maximum torque output of approximately 731 Nm. The engine complies with non-road Stage III emission standards. Power is transmitted through a six-forward and six-reverse powershift transmission. The crane achieves maximum travel speeds of approximately 38 km/h and offers gradeability of up to 55%, allowing efficient movement across rough construction terrain and undeveloped working areas.

The carrier chassis uses a compact two-axle rough terrain configuration with both axles driven and steered. Steering functions include front-wheel steering, rear-wheel steering, coordinated four-wheel steering, and crab steering. This steering flexibility significantly improves maneuverability in confined workspaces and crowded industrial sites. The front axle is rigidly mounted while the rear axle uses an oscillating arrangement with hydraulic suspension cylinders to improve terrain adaptability and wheel contact on uneven surfaces.

The outrigger system consists of four hydraulically controlled H-type outriggers capable of simultaneous or independent deployment. Outriggers can be positioned fully extended, partially extended, or fully retracted according to site limitations. Maximum outrigger spread reaches approximately 5.4 meters laterally and 5.1 meters longitudinally. Hydraulic locking systems integrated into the outriggers help ensure stability and safety during lifting operations.

The hydraulic system uses dual variable displacement piston pumps supplying the telescoping, hoisting, and luffing functions, while additional gear pumps supply steering, outriggers, slewing, and braking systems. Hydraulic oil capacity is approximately 650 liters. The slewing mechanism uses a hydraulic motor driving a planetary reducer connected to a slewing ring gear arrangement, delivering continuously variable slewing speeds from 0 to 2.8 rpm.

Operator comfort was also emphasized in the crane’s design. The side-mounted operator cab provides wide visibility through large glazed surfaces and incorporates ergonomic controls arranged according to ISO standards. The cab includes adjustable seating, air conditioning, pilot-operated hydraulic controls, and integrated monitoring systems. Safety devices fitted to the crane include a rated capacity indicator, boom angle indicator, anti-two-block system, hydraulic safety valves, outrigger beam warning devices, emergency stop systems, slewing locks, and hoist limit switches.
