Application Scenarios
Product Description
The QL-25 Mini Excavator is a heavy-duty and versatile construction machine engineered for high-performance excavation in professional environments. With a substantial operating weight of 2500 kg, it provides the superior stability and ground pressure of 23 kPa required for intensive earthmoving tasks.
Powered by premium engine options including the 22.1KW Laidong 385 or the reliable Kubota D1703, the QL-25 ensures consistent power delivery with a high displacement of 1.617 L. Its advanced TAITE hydraulic system, featuring a GEAR 12/12/04 pump and a 24/24 L/min flow rate, provides the smooth and responsive control needed for precise site preparation.
Designed for maximum productivity, the QL-25 features a large 45 L fuel tank to support extended working hours. With an impressive maximum digging radius of 3600 mm and a digging depth of 2000 mm, this machine offers the extended reach necessary for deep trenching and efficient material handling while maintaining a compact 1300 mm chassis width.
