2.8-Ton Compact Crawler Mini Excavator
2.8-Ton Compact Crawler Excavator | Superior Performance
The KAISAN KN28 is a high-performance 2.8-ton mini excavator powered by a durable Kubota D1105 diesel engine, generating 14 kW to handle challenging operations in tight spaces. With a maximum excavation depth of 2830 mm and a working radius of 4290 mm, it comes standard with a 0.1 m³ bucket. Its hydraulic system integrates an efficient variable displacement piston pump that delivers 61.6 L/min for precise and smooth control.
The machine is available with either rubber or steel track options and includes a 23-liter fuel tank for longer working cycles. Engineered for easy maintenance, the KN28 delivers consistent reliability and cost-effective performance, making it ideal for construction, landscaping, and utility applications.
The KN28 Crawler Excavator from Shandong Kaisan Machinery Co., Ltd. is built to excel in tight spaces, offering a versatile mix of compact design and powerful performance. Delivering 14 kW (2200 rpm) and 51.9 N·m of torque, its reliable Kubota D1105 engine drives a high-efficiency hydraulic system. This system features a variable piston pump that delivers 61.6 L/min flow at 20.5 MPa for smooth and precise operation. With an operating weight of 2750 kg and a 0.1 m³ standard bucket, it delivers a maximum digging depth of 2830 mm and a dumping height of 3005 mm. The machine's compact profile (2480 mm height, 4195 mm transport length) and low ground pressure (24 kPa) from its track options enhance on-site efficiency. Supported by a 23L fuel tank, the KN28 is perfectly suited for urban construction, landscaping, and various light industrial duties.
