Core Performance Features

High-efficiency PowertrainThe Cat C2.4 DI engine has strong adaptability to low-quality fuel in remote construction sites, with built-in dual fuel filtration (fuel water separator + secondary fuel filter) to reduce engine failure risk. Compared with the previous generation 305.5E model, it reduces fuel consumption by 8~10% under the same working load. It is also equipped with two work modes: Power mode for high-load excavation and demolition, and Economy mode for fine operation to cut operating costs.
Precise Hydraulic ControlThe load-sensing hydraulic system with independent flow distribution delivers smooth, jitter-free control for boom, arm and bucket movements, supporting high-precision operations such as fine trenching, landscaping shaping and fragile material handling. The system also supports quick coupling for multiple Cat original attachments, including hydraulic breakers, augers, grapples, rippers and forks, to cover diversified job demands.
Durable Structural DesignThe boom, arm and X-type undercarriage are made of high-strength wear-resistant steel, with all stress points reinforced by thickened plates and full penetration welding process to cope with long-term high-load work. The sealed track chain design reduces external impurity intrusion, extending track service life by 20% compared with similar products.

Operator Comfort & Safety

The cab meets ROPS (Roll Over Protective Structure) and FOPS (Falling Object Protective Structure) safety standards, providing all-round protection for operators.
Large-area panoramic glass eliminates operation blind spots, with optional rear camera to improve safety during reversing in narrow sites.
Ergonomic multi-adjustable suspension seat with lumbar support reduces fatigue during long working hours; low-force control joysticks are positioned within easy reach to reduce hand strain.
Standard high-efficiency air conditioning system with adjustable vents, radio with USB port, and multiple storage compartments for personal items improve operation experience.
A low-cost canopy option is available for users working in warm climates.

Easy Maintenance

All daily maintenance points (oil level check, filter replacement, lubricant filling) are arranged at ground level, eliminating the need to climb onto the upper frame and cutting daily maintenance time by 30%.
Large side-opening engine hood provides unobstructed access to core components such as the engine, hydraulic pump and radiator for overhaul.
Long-life Cat original hydraulic oil has a replacement interval of 4,000 working hours under normal use conditions, greatly reducing long-term operating costs.
Optional Product Link remote monitoring system supports real-time checking of working hours, fuel consumption, fault codes and machine location, helping fleet managers realize intelligent equipment management.

Typical Application Scenarios

Municipal engineering: Pipeline trenching for water, electricity and gas, road repair, sidewalk construction, urban greening maintenance
Landscaping: Tree pit excavation, site leveling, landscape reshaping
Rural construction: House foundation excavation, farmland water conservancy renovation, rural road construction
Small demolition: Interior demolition, small building dismantling when equipped with a hydraulic breaker
Material handling: Bulk material loading and unloading, stacking when equipped with a grab or fork attachment

Non flooded

No accident
