XCMG XCR90_AU Load Chart PDF + Specifications

The XCMG XCR90_AU is a modern rough terrain crane designed to perform heavy lifting tasks in challenging environments such as construction sites, mining operations, and infrastructure projects. As part of XCMG’s rough terrain crane lineup, the model combines strong lifting capacity with a highly mobile off-road chassis capable of travelling across uneven ground and confined job sites.

The crane has a maximum rated lifting capacity of 90 tonnes and is equipped with a five-section telescopic boom constructed with a high-strength U-shaped cross-section design. The boom has a base length of approximately 12.4 m and extends to about 48 m, providing a wide operating envelope for lifting operations. For applications requiring additional reach or height, the crane can be fitted with a two-section lattice jib measuring approximately 9 m or 15 m, which increases the maximum lifting height to around 63.1 m.

The telescoping system allows the boom sections to extend smoothly under load conditions, enabling efficient lifting operations across a wide working radius. This capability improves operational productivity, particularly in applications where the crane must frequently adjust its boom configuration during lifting tasks.

The XCR90_AU is mounted on a two-axle rough terrain carrier chassis designed specifically for off-road operation. The chassis frame is constructed from high-strength welded steel with a torsion-resistant box structure that provides durability under heavy loads. The crane uses large off-road tires sized 29.5R25, offering strong traction and stability when travelling over uneven ground or loose surfaces.

Power for the crane is supplied by a Cummins diesel engine rated at approximately 200 kW at 2000 rpm, providing the torque necessary for both travelling and crane operations. The engine complies with EU Stage V emission standards and is paired with a 4-speed transmission with three forward gears and three reverse gears, enabling smooth driving performance and efficient operation on construction sites.

The crane’s hydraulic system uses a dual-pump load-sensing design, which ensures efficient and responsive control of lifting, slewing, and boom movements. The load-sensing system automatically adjusts hydraulic output according to the demand of the operation, improving fuel efficiency and ensuring stable control even during simultaneous movements.

For stability during lifting operations, the XCR90_AU is equipped with four hydraulically operated outriggers, each capable of extending both horizontally and vertically. These outriggers provide a stable support base when lifting heavy loads at larger radii. Optional variable support technology allows different outrigger extension combinations to be used depending on the available working space.

The crane incorporates an advanced control system that enables precise operation of all crane movements. The integrated monitoring system displays operational parameters and lifting information, allowing the operator to monitor load conditions and crane status in real time. The operator cab is designed with a wide field of view and ergonomic controls to improve comfort and operational safety.

Mobility is enhanced through a multi-mode steering system that allows the crane to switch between different steering modes for improved maneuverability in confined spaces. These steering modes allow the front and rear axles to steer independently or together, reducing turning radius and improving handling on narrow job sites.

In terms of operational efficiency, the crane incorporates several energy-saving technologies. The hydraulic system includes a large-displacement variable pump and gravity-assisted lowering functions, which help reduce fuel consumption during lifting operations. The drivetrain also uses a hydraulic torque converter to improve efficiency during both high-speed travel and low-speed heavy-load movement.

Overall, the XCMG XCR90_AU is designed to provide a balance between lifting performance, mobility, and operational efficiency. With its 90-ton lifting capacity, 48-m telescopic boom, optional jib reaching over 63 m, and robust off-road chassis, the crane is well suited for construction, mining, energy, and infrastructure projects where strong lifting capability and reliable off-road performance are essential.
