Core Advantages

1. Reliable Power & Good Fuel‑Saving Performance

Equipped with CAT C2.4 DI four‑cylinder diesel engine, gross power 34.1 kW (45.7 hp), rated net power 31.1 kW (41.7 hp), complying with Tier3 / China Stage III emission standards. Matched with intelligent economy mode and auto‑idle function to cut unnecessary fuel consumption. Operating weight: 5400 kg. Compact short‑tail‑swing structure allows free rotation in narrow job‑sites without collision risk. Light unit weight facilitates road transport between job sites.

2. Load‑Sensing Hydraulic System & Reliable Working Performance

Adopts CAT HDH high‑definition load‑sensing flow‑sharing hydraulic system, featuring fast response, smooth movement and high operation precision信昌机器. Real‑time flow‑pressure matching reduces ineffective energy loss and shortens working cycle time. Key working parameters: ‑ Maximum digging depth: 3870 mm ‑ Maximum ground‑level reach: 5955 mm ‑ Maximum dumping height: 4170 mm ‑ Standard bucket capacity: 0.22 m³ ‑ Main hydraulic working pressure: 25 MPa ‑ Max auxiliary hydraulic flow: 80 L/min ‑ Bucket digging force: 35 kN; Stick digging force: 27.2 kN

Standard two‑speed travel system adapts to muddy ground, slope and complex narrow terrain. Grease‑lubricated heavy‑duty undercarriage resists mud, dust and abrasion, extending service life of track shoes, rollers and other wearing components公司网络安.... Equipped with floating‑function dozer blade for back‑filling and site leveling.

3. Operator‑Friendly Cab & Complete Safety Configuration

ROPS/FOPS certified cab meets international roll‑over and falling‑object protection standards. Spacious interior with ergonomic layout, upgraded multi‑function pilot joysticks and mechanical suspension seat effectively relieve operator fatigue during long‑time continuous shifts. Large tempered glass provides panoramic all‑round view. COMPASS digital monitor integrates equipment status monitoring, fault self‑diagnosis function for real‑time machine condition check. Optional heating & air‑conditioning system adapts to high‑temperature and low‑temperature harsh environments.

4. Reinforced Structure & Convenient Maintenance Design

Boom, stick and key chassis stress‑bearing parts adopt high‑strength wear‑resistant steel with reinforcement optimization, featuring good anti‑impact and anti‑torsion performance, suitable for digging, breaking and other small‑scale heavy‑duty working conditions. Upgraded sealing for hydraulic pipelines and joints lowers oil‑leakage risk.

Large side‑opening service covers enable ground‑level maintenance access. Filters, oil filling ports and detecting points are centrally arranged. Routine inspection can be completed without lifting cab, saving daily maintenance time and labor cost, lowering failure rate and improving machine attendance rate信昌机器.

5. Rich Attachment Compatibility & Multi‑Scenario Adaptability

Optional auxiliary hydraulic pipelines support quick coupler for fast tool replacement to realize multi‑function operation: ‑ Standard buckets, heavy‑duty wear‑resistant buckets ‑ Hydraulic breakers for concrete breaking & demolition ‑ Augers for foundation hole‑drilling ‑ Hydraulic thumbs for bulk material sorting & handling ‑ Grading buckets & rakes for site leveling, landscaping trimming

Multiple attachments maximize machine utilization rate and realize one‑machine multi‑purpose.
