ZOOMLION Crane

Overview of the Zoomlion ZTC750 Truck Crane

The Zoomlion ZTC750 is a 75-ton hydraulic truck-mounted crane engineered for heavy-lift operations across construction, mining, energy, and large infrastructure projects. Built on a 3-axle carrier, the ZTC750 balances road mobility with class-leading lifting capability — operators can drive the unit between spread-out job sites at up to 75 km/h, then deploy the crane's 44 m five-section telescopic boom plus optional jib configuration to handle rated lifts up to a maximum working height of 60.2 m.

The ZTC750 is part of Zoomlion's flagship truck crane lineup — a series widely deployed across the Middle East, Africa, Southeast Asia, and South America for its combination of performance, parts availability, and competitive price point.

Key Specifications at a Glance

Lifting Performance and Boom System

The ZTC750's 5-section telescopic main boom extends from 11.6 m to 44 m, giving operators the reach flexibility needed for tall-structure and wide-radius work sites. Two jib configurations are available — a 9.5 m jib for shorter auxiliary reach and a 16 m jib for maximum 60.2 m lifting height — making the crane adaptable to tower-style construction, wind turbine installation, and bridge pier work.

Key lifting performance highlights:

• Max rated capacity: 75 t × 3.0 m working radius (base boom)

• Base boom moment: 2,352 kN·m — strong in its 75-ton class

• Longest main boom moment: 1,098 kN·m

• Boom extension time: 107 s

• Boom elevation (derricking) time: 57 s

• Single-rope max hoist speed: 135 m/min (main winch)

The central slewing position is optimized for rear lifting, increasing capacity in the most common working arc.

Engine and Drivetrain

The ZTC750 is configured for sustained heavy-lift operation, with a drivetrain engineered to handle 37% gradeability on unpaved job-site terrain. The carrier supports long-distance road travel at 75 km/h and is compatible with a range of internationally supplied diesel engines — confirm the specific engine model (typically Weichai WP10/WD615 series or comparable) with the seller per unit.

Carrier and Mobility

The 3-axle carrier balances maneuverability with lifting strength. With a minimum turning radius of 12 m and a ground clearance of 280 mm, the ZTC750 navigates typical construction and industrial-site conditions without excessive ground-prep work.

• Max travel speed: 75 km/h

• Gradeability: 37%

• Min turning radius: 12 m

• Min ground clearance: 280 mm

Slew System and Outriggers

The crane features full-power 360° continuous slewing at variable swing speeds up to 1.8 r/min, enabling precise load positioning in any direction without re-positioning the carrier. Hydraulic outriggers with a 6.0 m longitudinal × 7.6 m lateral span provide a stable base for rated lifts across the full working radius — the wide lateral span in particular improves stability during long-reach and high-load operations.

Dimensions, Axle Loads, and Weight

• Overall length: 14,100 mm

• Overall width: 2,750 mm

• Overall height: 3,750 mm

• Kerb (traveling) mass: 44,870 kg

• Front axle load: 19,000 kg

• Rear axle load: 26,000 kg

• Shipping package dimensions: 12,780 × 2,500 × 3,400 cm (gross weight 32,000 kg for containerized export)

These figures confirm the ZTC750's compliance with most heavy-haul road-permit regulations, though specific axle-load rules vary by country.

Applications and Industries Served

The Zoomlion ZTC750 is widely used across:

• Heavy construction — high-rise structural steel, large-formwork lifts, precast concrete placement

• Industrial installation — power-station equipment, refinery modules, plant machinery setting

• Mining operations — equipment handling, mill relocations, conveyor structure installation

• Energy projects — wind turbine installation (with jib), transformer lifts, solar-farm pile driving

• Bridge construction — long-span girder placement, pier cap work

• Infrastructure megaprojects — rail, port, dam, and road construction

• Crane rental operations — fleet staple for heavy-lift rental yards

Why Choose the Zoomlion ZTC750

• Class-leading capacity at 75 t base lift with 2,352 kN·m base-boom moment

• Long reach — 44 m boom + 9.5 m or 16 m jib for up to 60.2 m lifting height

• Optimized central slewing position increases rear-arc lifting capacity

• 360° continuous full-power slewing for productivity in multi-direction lifts

• Wide outrigger span (7.6 m lateral) for stability at heavy radii

• Strong road mobility at 75 km/h for self-deployment between job sites

• Globally supported by Zoomlion's expanding international parts and service network

Buyer Inspection Checklist (Used Units)

Used Zoomlion ZTC750 units vary widely in condition and configuration. Before purchasing, verify:

• Telescopic boom sections for wear, dents, pin lubrication, and cylinder seals

• Hydraulic system pressure, oil cleanliness, and leak history

• Outriggers — pad condition, beam straightness, cylinder seals

• Engine — operating hours, service records, emissions compliance

• Tires — tread depth, age, load rating

• Safety devices — LMI (load moment indicator), anti-two-block, hoisting limit switches

• Cab condition — controls, instrumentation, A/C, gauges

• Hook blocks, wire ropes, sheaves, and counterweight configuration

• Installed jib — 9.5 m, 16 m, or not installed

• Slew system — gear mesh, hydraulic motor, slew bearing condition

• Total traveling mass and axle loads vs. local road regulations

Zoomlion ZTC750 vs Competitors

How the ZTC750 positions in the global 75-ton truck crane market:

The ZTC750 is competitive on boom reach and outrigger span while typically being priced below comparable European or Japanese 75-ton truck cranes — making it a frequent choice for cost-sensitive heavy-lift operators.

Frequently Asked Questions
