Zoomlion ZRT1100 Load Chart PDF + Specifications

The Zoomlion ZRT1100 was introduced as a modern rough terrain crane focused on combining lifting capacity, mobility, and operational efficiency within compact dimensions. Built primarily for refinery construction, industrial maintenance, oil and gas projects, and infrastructure work, the crane is capable of operating effectively on uneven terrain and in restricted spaces where larger truck cranes or crawler cranes may not be practical.

The crane is equipped with a five-section full-power telescopic boom fabricated from high-strength steel using a U-shaped boom profile for improved structural rigidity and reduced weight. The main boom extends hydraulically from 12.5 meters to 45 meters and uses synchronized telescoping cylinders and rope systems to ensure smooth extension and retraction. The boom head incorporates five sheaves for efficient reeving changes and simplified hook block configuration. Boom raising angles range from -1° to 80°, allowing the crane to handle both low-radius heavy lifts and high-angle lifting applications. Full boom extension or retraction requires approximately 135 seconds, while boom luffing up or down takes around 60 seconds.

For applications requiring greater lifting height or additional outreach, the ZRT1100 can be fitted with a two-section lattice swing-away jib. The jib length ranges from 10.4 meters to 17.5 meters and supports offset positions of 0°, 15°, and 30°. The jib is side-stowed alongside the boom during transport and can be hydraulically installed during setup. With the jib attached, the crane achieves a maximum lifting height of approximately 63.6 meters, while the main boom alone provides a lifting height of approximately 46.2 meters from ground level.

The crane has a maximum rated lifting capacity of 110 tonnes at a 2.5-meter radius and develops a maximum lifting moment of 338 tonne-meters. Even at full boom extension, the crane maintains a lifting moment of approximately 105 tonne-meters. The lifting charts provided in the specification manual demonstrate strong load capacities across multiple outrigger configurations including fully extended, mid-position, fully retracted, and on-tire operations. These multiple working configurations allow the crane to adapt efficiently to limited site space or uneven ground conditions.

The hoisting system uses independent hydraulic main and auxiliary winches mounted at the front of the slewing platform. Both winches are driven through variable displacement hydraulic motors and planetary reduction gearboxes. The main winch stores approximately 260 meters of 22 mm wire rope while the auxiliary winch carries around 140 meters. Maximum single-line rope speed reaches 130 meters per minute and maximum line pull is approximately 6,500 kg. Rotatable hook blocks include an 85-ton six-sheave main hook block, a 65-ton hook block, an optional 110-ton seven-sheave hook block, and a 35-ton auxiliary hook.

Power is supplied by a Cummins QSB6.7 turbocharged six-cylinder diesel engine producing 194 kW at 2,000 rpm with maximum torque output of approximately 990 Nm at 1,500 rpm. The engine complies with non-road emission Stage III standards. Power is transmitted through a powershift transmission offering six forward and six reverse gears. The crane achieves a maximum traveling speed of approximately 35 km/h and is capable of climbing gradients up to 56.7%, giving the machine strong mobility across rough terrain and undeveloped construction sites.

The carrier chassis uses a two-axle rough terrain configuration with both axles driven and steered. Steering is hydraulically powered and offers four steering modes including front-wheel steering, rear-wheel steering, four-wheel coordinated steering, and crab steering. These steering functions provide exceptional maneuverability in confined working areas and improve positioning accuracy during lifting operations. The front axle is rigidly mounted while the rear axle incorporates an oscillating suspension arrangement with hydraulic suspension cylinders for improved ground contact and stability on uneven surfaces.

The outrigger system consists of four hydraulically controlled H-type outriggers capable of simultaneous or independent deployment. Outrigger spread reaches approximately 7.65 meters laterally and 7.6 meters longitudinally when fully extended. Intermediate and fully retracted outrigger positions are also supported, enabling lifting operations in restricted areas. Hydraulic locks integrated into each outrigger cylinder provide safety during lifting operations.

The hydraulic system uses multiple pumps dedicated to different functions. Variable displacement piston pumps power telescoping, hoisting, and luffing operations, while gear pumps handle slewing, steering, outriggers, and brake functions. Hydraulic oil capacity is approximately 1,100 liters. The slewing system uses a hydraulic motor driving a planetary reducer with a pinion-and-ring gear arrangement, delivering continuously variable slewing speeds from 0 to 1.6 rpm.

Operator comfort and safety were key design priorities for the ZRT1100. The crane features a modern side-mounted operator cab with left-hand drive configuration and panoramic glazing for improved visibility. The cab is equipped with an adjustable suspension seat incorporating heating and cooling ventilation, air conditioning, ergonomic hydraulic controls, and multifunction electronic displays designed according to ISO standards. Safety systems include a rated capacity indicator, boom angle indicator, anti-two-block device, hydraulic safety valves, hoist limit switches, emergency stop systems, slewing lock device, and outrigger warning indicators.
