Rugged and Durable Structure Reinforced Working Attachments: Both the boom and arm utilize a box-type design. Reinforced plates and higher-strength steel are used in key stress areas, providing enhanced bending and torsion resistance and exceptional durability, making them particularly suitable for harsh working conditions and heavy loads. Sturdy Undercarriage: The wider and longer track frame enhances overall stability. Standard reinforced track shoes and carrier rollers offer excellent wear resistance and long service life. The integrated travel motor and reducer design delivers a compact structure, high driving force, and excellent gradeability and maneuverability.Convenient Maintenance Easy-to-Maintain Design: Centralized Maintenance Points: Routine maintenance components such as the air filter, diesel filter, oil filter, and hydraulic oil filter are conveniently located and accessible through the side door. Large-Opening Cover: The engine hood features a wide opening, and some models even tilt sideways, providing ample space for routine inspections and overhauls, saving maintenance time and costs. Long Maintenance Intervals: The use of long-lasting filters and high-quality oils effectively extends the replacement intervals for engine oil, hydraulic oil, filters, and other components, reducing long-term operating costs and downtime.High Overall Cost-Effectiveness Compared to comparable tonnage engines from leading international brands (such as Caterpillar, Komatsu, and Volvo), the SY135C offers a more competitive initial purchase price, lowering the investment threshold. Low Operating Costs: Thanks to its excellent fuel economy, high reliability, and convenient, low-cost maintenance, the SY135C effectively controls its operating expenses (OPEX) throughout its lifecycle, delivering a higher return on investment (ROI) for owners.
