Core Advantages

1. Reliable Power & Excellent Fuel‑Saving Performance

Equipped with CAT C3.3B turbocharged diesel engine, rated net power 48.5 kW (65 hp), complying with Tier 4 Final / Stage IIIB emission standards. Matched with intelligent economy mode, fuel consumption can be reduced by up to 20 %. Auto‑idle function will lower engine speed after 4‑second inactivity to cut extra fuel wasteCat. Operating weight: 7 160‑8 400 kg. It outputs solid digging force while keeping low whole‑machine weight, convenient for road transportation. Compact short‑tail‑swing structure allows free rotation in narrow job sites without hitting walls or obstacles.

2. High‑Definition Intelligent Hydraulic System & Superior Working Performance

Adopts CAT High‑Definition load‑sensing flow‑sharing hydraulic system, featuring fast response, smooth action and high operation precision. Real‑time matching of flow and pressure reduces ineffective energy loss and shortens working cycle timeCat. Key working parameters: ‑ Maximum digging depth: 4 643 mm ‑ Maximum ground‑level reach: 7 130 mm ‑ Maximum dumping height: 5 170 mm ‑ Standard bucket capacity: 0.38‑0.44 m³ ‑ Main hydraulic system pressure: 27.5 MPa ‑ Maximum auxiliary flow: 110 L/min

Standard two‑speed travel system adapts to muddy ground, slope and complex narrow terrain. Reinforced heavy‑duty undercarriage resists mud, dust and abrasion, extending service life of track shoes, rollers and other wearing components.

3. Human‑Centered 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 joysticks and adjustable suspension seat greatly relieve operator fatigue during long‑time continuous work. Large tempered glass gives panoramic all‑round view. Built‑in COMPASS digital monitor integrates equipment monitoring, fault self‑diagnosis and anti‑theft password start‑up function, real‑time displaying machine working status. Optional heating & air‑conditioning system adapts to high‑temperature and low‑temperature harsh environmentsCat.

4. Reinforced Structure & Easy‑Access Maintenance Design

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

Side‑opening service covers allow ground‑level maintenance access. Filters, oil filling ports and detecting points are centrally arranged, no need to lift cab for routine inspection. It saves daily maintenance time and labor cost, lowers failure rate and improves machine attendance rate.

5. Rich Attachment Compatibility & Strong Multi‑Scenario Adaptability

Standard dual‑way auxiliary hydraulic pipelines support quick coupler for fast tool replacement, realizing 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 for one‑machine multi‑purpose jobs.

Typical Application Scenarios

1. Municipal Engineering & Urban RenewalSuitable for city road maintenance, sidewalk reconstruction, underground pipeline trenching, old community renovation and narrow‑zone demolition. Compact short‑tail‑swing design works safely beside buildings and street obstacles.
2. Landscaping & Horticultural ProjectsFor park construction, tree‑planting pit digging, terrain reshaping, pond excavation and green‑belt finishing. Precise hydraulic control guarantees fine‑grading effect.
3. Residential & Small‑Scale ConstructionFoundation excavation for villas & small buildings, backfill compaction, material handling and site cleaning. Easy to transport and flexible for scattered small jobs.
4. Rural & Agricultural ProjectsFarmland consolidation, irrigation channel digging, fish‑pond excavation, farm road renovation. Reliable performance adapts to field muddy working conditions.
5. Indoor & Confined‑Space DemolitionShort tail swing makes it ideal for indoor dismantling, basement reconstruction and compact job sites where large excavators cannot enter.
