Application Scenarios
Product Description
The QL-22 Mini Excavator is a robust and high-capacity construction machine engineered for demanding excavation tasks that require both power and precision. With an operating weight of 2200 kg, it offers superior stability and a significant 12 kN bucket digging force, making it ideal for intensive landscaping, utility trenching, and medium-scale construction projects.
Powered by a high-performance engine system—with options including the 22.1 KW Laidong 385 or the reliable Kubota D1703 (18.2 KW)—the QL-22 ensures powerful performance and reliable operation at a rated speed of 2200 RPM. Its advanced hydraulic system, featuring a TAITE main pump and a 24/24 L/min flow rate, provides the smooth, responsive control necessary for professional-grade earthmoving and site preparation.
The machine features a stable chassis with a width of 1300 mm and a platform tail slewing radius of 1150 mm, allowing it to maintain a compact footprint while delivering heavy-duty results. With an impressive Max. Digging Depth of 2000 mm and a Max. Digging Radius of 3800 mm, the QL-22 provides the extended reach and 3200 mm digging height required for efficient loading and deep excavation in a variety of challenging terrains.
