Zoomlion ZAT4500V853 Load Chart PDF + Specifications

The Zoomlion ZAT4500V853 was introduced as part of Zoomlion’s next-generation all terrain crane lineup aimed at increasing lifting performance while maintaining strong transport mobility and operational efficiency. Positioned in the 450-ton capacity segment, the crane was engineered primarily for large-scale wind power erection, refinery construction, bridge installation, and infrastructure projects where long reach and heavy lifting capability are critical requirements.

One of the most notable features of the ZAT4500V853 is its exceptionally long eight-section telescopic main boom. Constructed from 1100 MPa high-strength steel with an optimized oval boom profile, the boom extends from 15.4 meters to 90 meters. This gives the crane one of the longest telescopic booms available in the 450-ton class. The maximum lifting height on the main boom reaches 90 meters, while the addition of lattice jib systems increases lifting height to 108 meters or 128 meters depending on the configuration selected.

The crane is equipped with both light and heavy jib systems. The light swing-away jib is available in 20 m and 28 m standard lengths, with optional extensions to 37.5 m and 45.5 m through the addition of 8-meter inserts. Under superlift conditions, the light jib configurations become 24.5 m, 32.5 m, 40.5 m, and 48.5 m. For heavier duty applications, the crane can be fitted with a heavy luffing jib system composed of transition sections, A-frame structures, lattice inserts, and variable-angle heavy jib sections. Heavy luffing jib lengths are available in 13 m, 17 m, 21 m, 25 m, 33 m, and 41 m configurations. The heavy jib can only be operated in conjunction with the optional Y-type superlift system.

The ZAT4500V853 has a maximum rated lifting capacity of 450 tonnes and produces a maximum lifting moment of 1,080 tonne-meters on the basic boom. Even with the main boom fully extended, the crane maintains a maximum lifting moment of 379 tonne-meters, highlighting the structural efficiency of the long telescopic boom. The boom elevation range spans from -0.4° to 82°, enabling both low-angle heavy lifting and high-angle long-radius work. The telescoping mechanism utilizes a top-pin single-cylinder automatic pinning system with programmable sequential extension and real-time display of boom extension status on the crane monitor.

The crane’s upper structure is powered by a Weichai WP7G270E301 inline six-cylinder turbocharged and intercooled diesel engine. The engine produces 199 kW at 2,000 rpm with a maximum torque output of 1,200 Nm between 1,200 and 1,500 rpm. The hydraulic system combines open and closed-loop circuits, with closed-loop control for slewing operations and open-loop valve control for hoisting, luffing, telescoping, and auxiliary functions. The main hoist achieves a maximum single-line rope speed of 125 m/min while the slewing system offers continuously variable rotation speeds from 0 to 1.4 rpm. Boom raising time is approximately 80 seconds while full extension of all eight boom sections requires approximately 900 seconds.

The optional superlift system is a Y-type equal-length rope configuration utilizing a single-piece structure mounted at the 85-meter boom head section. The superlift attachment substantially increases lifting capacity at long radii and with heavy luffing jib configurations. Installation of the superlift system requires the assistance of an auxiliary crane.

The carrier chassis is a six-axle all terrain platform utilizing a 12×8 drive configuration. Axles one, three, four, and five are steering drive axles while axles two and six are steering non-driven axles. The chassis is powered by a Weichai WP15H660E50 inline six-cylinder turbocharged diesel engine compliant with Euro V emission regulations. The engine develops 485 kW at 1,800 rpm and produces a maximum torque output of 3,200 Nm between 900 and 1,400 rpm. Power is transmitted through a FAST F12JZ32A mechanical automatic transmission with integrated hydraulic retarder and two-speed transfer case. The crane can travel at speeds up to 80 km/h and climb gradients up to 45%.

The ZAT4500V853 employs a sophisticated hydro-pneumatic suspension system with axle load balancing and adjustable suspension height. Functions include chassis leveling, grouped axle balancing, rigid lockout, flexible suspension support, full chassis lifting, side lifting, and independent lifting of the third and fourth axles. The crane also incorporates six steering modes controlled through electro-hydraulic proportional steering systems. Despite its large dimensions, the minimum turning diameter is approximately 24 meters. Overall transport dimensions are 17.07 meters long, 3 meters wide, and 4 meters high, while transport weight without hooks, counterweights, jib, and auxiliary components remains below 72 tonnes.

Counterweight design is highly modular to simplify transportation and onsite assembly. Standard counterweight totals 110 tonnes, consisting of a 4-ton counterweight frame, a 16-ton base slab, two 5-ton slabs, and eight 10-ton slabs. For superlift applications, an additional four 10-ton slabs can be added, increasing total counterweight to 150 tonnes. Counterweight configurations include 0 t, 30 t, 50 t, 70 t, 90 t, 110 t, and 150 t arrangements depending on lifting requirements. The crane is capable of self-installing its own counterweights using the onboard boom and counterweight lifting system.

The crane is fitted with Zoomlion’s advanced intelligent safety and monitoring systems utilizing full CAN-BUS communication architecture. Multiple sensors and encoders continuously monitor outrigger reaction forces, chassis inclination, boom configuration, and operational status in real time. The machine integrates upgraded safety logic to prevent overloads and dangerous operating conditions while enhancing efficiency during complex lifting operations.

Operator comfort received significant attention in the 4.0 series design. The upper operator cab is a panoramic large-space cabin with sliding door access, outward-opening front glass, integrated electronic controls, and a 10.4-inch touchscreen display. The cab can tilt from 0° to 20° to improve visibility during high-angle lifting operations. The lower driver’s cab adopts a low-mounted full-width steel structure with adjustable steering column, air suspension seating, large multi-angle mirrors, electric windows, MP3 system, USB ports, heating and air-conditioning systems, and integrated electronic instrumentation for improved long-distance travel comfort.
