PRODUCT OVERVIEW

Product Overview

The XQ-WZ420D 4WD backhoe loader combines front loader and rear excavator functions in one multifunctional construction machine. With an operating weight of 7100 kg, transport dimensions of 7600 × 2360 × 2890 mm and four-wheel drive, it is designed for loading, digging, trenching, backfilling and general material handling work.

The front loader uses a 1.5 m³ 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 aggregate loading, site cleaning, material transfer and other front-loader operations.

The rear backhoe is equipped with a 0.3 m³ digging bucket and provides a maximum digging depth of 4100 mm. An optional telescopic arm can extend the digging depth to 5000 mm, while the 190° backhoe swing angle supports trenching and excavation over a wider working area.

The XQ-WZ420D 4WD backhoe loader uses a Yunnei YN38GBZ turbo engine with 76 kW rated power as standard. A YJ280 torque converter, fixed-shaft powershift gearbox, 4 forward and 4 reverse gears and a maximum travel speed of 30 km/h provide practical travel and working performance.

The hydraulic system operates at 22 MPa and provides 46.5 kN backhoe bucket digging force and 31 kN loader bucket breakout force. Hydraulic pilot control, A-type stabilizers and four-wheel drive support loading and rear excavation operations, while the standard luxury cab includes a sunroof, heating, adjustable rotating seat, adjustable instrument panel and LCD display.

A range of optional front and rear attachments is available for different job-site requirements, including material handling, trenching, breaking, drilling and specialized loading work. Together with its 39 kN maximum traction force, 300 mm minimum ground clearance and combined loader-backhoe structure, the XQ-WZ420D 4WD backhoe loader provides a flexible solution for construction, road maintenance, drainage, municipal and rural engineering applications.
