The XQ-WZ420D 4WD backhoe loader is a multifunctional construction machine that combines front loading and rear excavation functions in one unit. It is designed for loading, digging, trenching, backfilling and material handling work across construction, road maintenance, municipal and rural engineering applications.<\/p>\n
The machine has an operating weight of 7100 kg and transport dimensions of 7600 \u00d7 2360 \u00d7 2890 mm. A 2250 mm wheelbase, 300 mm minimum ground clearance and four-wheel drive configuration provide a practical platform for job-site travel, loading and excavation work.<\/p>\n
The front loader is equipped with a 1.5 m\u00b3 bucket and provides a loader lifting capacity of 2800 kg. A 38 kN breakout force, 2800 mm bucket dumping height and 1062 mm bucket dumping reach support loading, material transfer, site cleaning and general handling operations.<\/p>\n
The rear backhoe uses a 0.3 m\u00b3 digging bucket and provides a standard maximum digging depth of 4100 mm. An optional telescopic arm can extend the digging depth to 5000 mm, while the 190\u00b0 backhoe swing angle supports trenching and excavation across a wider working area.<\/p>\n
The XQ-WZ420D 4WD backhoe loader is powered as standard by a Yunnei YN38GBZ turbo engine with 76 kW rated power. The engine uses an inline, direct-injection, four-stroke and water-cooled design. Model-specific optional engines include the YUCHAI YCD4T33T6-115 rated at 90 kW, CUMMINS 4BT3.9-C100 rated at 74 kW, CUMMINS EURO 3 QSB3.9-C100 rated at 75 kW, and EURO 5 YUCHAI 81 kW or EPA 4 CUMMINS 74 kW engine options.<\/p>\n
The transmission system uses a YJ280 single-stage, single-phase, three-element torque converter with pressurized oil circulation and a fixed-shaft powershift gearbox. The machine provides 4 forward and 4 reverse gears with a maximum travel speed of 30 km\/h.<\/p>\n
The FEICHENG YUNYU front steering drive axle uses double reduction and single-stage wheel hub final reduction. The machine provides a maximum traction force of 39 kN, a steering angle of \u00b136\u00b0 and a minimum turning radius of 6581 mm.<\/p>\n
The hydraulic system operates at 22 MPa and provides a backhoe bucket digging force of 46.5 kN and a loader bucket breakout force of 31 kN. Loader bucket cycle times include 5.4 seconds for lifting, 3.1 seconds for lowering and 2.0 seconds for dumping.<\/p>\n
The service brake uses a caliper disc brake with air-over-hydraulic actuation and an external, self-adjusting and self-balancing brake structure. The parking and emergency brake system uses braking applied by actuating force with manual brake release.<\/p>\n
The standard configuration includes a front loader bucket, backhoe digging bucket, luxury cab with interior trim, fan, LED lights, large reversing camera display, emergency glass hammer, fire extinguisher, sliding windows, sunroof, heating, luxury adjustable rotating seat, adjustable instrument panel, LCD display, hydraulic pilot control and A-type stabilizers.<\/p>\n
A range of optional front loader and backhoe attachments is also available for different working requirements, including quick couplers, pallet forks, multipurpose buckets, grapples, snow blade, dozer blade, hydraulic breaker, auger, extension arm, telescopic arm and digging buckets in multiple widths.<\/p>\n
With front loading, rear excavation, four-wheel drive and flexible attachment capability in one machine, the XQ-WZ420D 4WD backhoe loader provides a versatile solution for construction, trenching, drainage, road maintenance, rural infrastructure, municipal projects and general material handling work.<\/p>","protected":false},"excerpt":{"rendered":"
