The Hyundai HW155 is the new-generation China Stage IV six-cylinder flagship wheeled excavator, built for municipal construction, road repair and widening, earthmoving and lifting and breaking duties. With a 14,300 kg operating weight, a standard 0.58 m³ bucket (0.65 m³ optional), it combines strong power, low fuel consumption, high reliability, ride comfort and operating safety in one machine — a high-value mainstay of the wheeled excavator market.

From its Cummins B7 six-cylinder engine and imported German ZF drivetrain to the EPFC electronic positive-flow control system, reinforced structures, fully intelligent cab and comprehensive standard safety equipment, the HW155 is designed to keep your projects moving and your costs down. This guide covers its five core advantages, plus the export and after-sales support available through Tianheng Construction Machinery.

Quick Specifications: Hyundai HW155

Six-Cylinder Power and Upgraded Hydraulics: High Efficiency, Low Consumption

Cummins B7 six-cylinder: 125 kW and 746 N·m

The Hyundai HW155 is powered by a Cummins B7 six-cylinder engine rated at 125 kW at 2,000 rpm, with a maximum output torque of 746 N·m at 1,200 r/min. Ample power reserve and strong torque output deliver the digging force heavy-load earthworking demands.

China Stage IV aftertreatment with proven fuel economy

DOC+DPF+SCR aftertreatment meets China Stage IV emission requirements, and matched low-sulfur diesel operation keeps fuel economy excellent. Export-market configurations may differ, so confirm the compliance package for your destination country with our sales team.

EPFC electronic positive-flow control: 9% less fuel per shift

The EPFC electronic positive-flow control system adds dual-flow combination modes such as boom+swing and boom+arm to match different working conditions. In P mode, combined fuel consumption per shift is 9% lower than the previous generation.

ECO Guidance and dual-end fuel monitoring

The ECO Guidance intelligent interaction system coaches energy-saving operating habits through icon prompts, while panel and mobile-phone dual-end fuel monitoring puts real-time consumption data at your fingertips — keeping cost fully under control.

Imported ZF Drivetrain: Outstanding Transfer Mobility

German ZF drive axle and transmission

The whole machine is configured with a German ZF drive axle and transmission. Core drivetrain components deliver reliable quality and high durability — the foundation of wheeled-excavator productivity.

40.5 km/h road speed with creep walking function

A maximum travel speed of 40.5 km/h combined with the creep walking function greatly improves transfer efficiency between jobsites while optimizing travel-cycle fuel consumption — machine mobility and driving economy in both directions.

11.4 r/min swing for fast cycles

A swing speed of 11.4 r/min fully exploits the inherent advantage of wheled excavators in fast transfer and quick truck-passing cycles.

Reinforced Structure: Durable and Reliable in Harsh Conditions

Verified frames and improved lifting stability

The upper and lower frames have passed rigorous impact and load verification, with cast-steel components used at key points of the front attachment and the swing bracket proven by long-term durability testing. An optimized configuration significantly improves lifting stability.

4.60 m boom, 2.10 m arm and wear-resistant bucket

The 4.60 m boom and 2.10 m arm provide a wide working envelope. The standard 0.58 m³ high-wear-resistant bucket features anti-shedding tooth design and thickened wear-resistant steel plate welding at the bottom for stronger digging resistance.

Load-sensitive temperature-controlled fan

The load-sensitive electronic hydraulic temperature-controlled fan adjusts cooling intelligently according to hydraulic oil temperature, keeping operation stable in high-ambient environments and reducing the risk of failure-related downtime.

Fully Intelligent Cab: A Better Operating Experience

Quieter, better-ventilated workspace

The cab is welded from high-strength low-alloy steel with optimized sealing, cutting cab noise by 3.4 dB. A newly added face-level air outlet keeps the operator comfortable through long shifts.

8-inch smart touch monitor with OTA upgrades

The monitor is upgraded to an 8-inch smart touch-control panel (previous generation: 7 inches), supporting daily and weekly fuel consumption statistics, remote program upgrades and economic operation guidance — more freedom in human-machine interaction and less fatigue over long working hours.

Comprehensive Standard Safety: Lower Additional Modification Cost

Protective nets, emergency stop and rear-view camera as standard

Front and rear protective nets, an under-seat one-key emergency stop switch and a rear-view camera are all fitted at the factory, guarding people and machine from every angle — with no retrofit expense.

Factory breaker piping: attachments ready to work

Factory or kit hydraulic breaker piping with direct connection and a high degree of whole-machine hydraulic matching mean no later modification is needed. Breaking, digging and multi-layer tool switching are ready to use out of the box, balancing operating safety with convenience. Compared with the previous generation, the new EPFC electronic positive-flow control, ECO Guidance smart fuel-saving guidance, combination speed modes and electronic hydraulic temperature-controlled fan complete a full intelligent-configuration upgrade.

Best-Fit Applications for the HW155

• Municipal construction: Fast road-speed transfers and compact wheeled agility suit city utilities and maintenance fleets.

• Road repair and widening: Creep walking function enables precise positioning along roadways and shoulders.

• Earthmoving operations: Six-cylinder torque and the 0.58/0.65 m³ bucket handle heavy-load digging and loading.

• Lifting duties: Optimized configuration and verified structures deliver significantly improved lifting stability.

• Breaking work: Factory breaker piping and high hydraulic matching make hammer operation ready from day one.
