三一重工 235

Sany 235 Excavator (main models SY235H/SA/S) is a benchmark work of 23-ton medium-sized hydraulic excavators, specially built for earth and rock works, mining stripping, municipal infrastructure, tunnel construction and other working conditions. With the core advantages of dual power options, full electronic control high-efficiency hydraulics, low consumption and energy saving, it won the 2025 Construction Machinery Annual Product Golden Finger Award, with a market share of nearly 30% in the same class, becoming a classic hit of domestic medium excavators. The whole machine offers two imported engine options: Isuzu 4HK1 and Deutz TCD5.7, with rated power of 128kW/2000rpm and 129kW/2100rpm respectively, both complying with China IV/EU Stage IIIA emission standards. The Isuzu model adopts DOC+DPF+EGR aftertreatment solution without urea filling, and completes the 2000H inferior diesel durability test without shutdown, with full reliability. It has outstanding core operation performance, standard equipped with a 1.35m³ large-capacity bucket, with bucket digging force of 158kN and arm digging force of 124kN, and the digging efficiency is more than 20% higher than the previous generation; the maximum digging depth is 6450mm and the maximum digging radius is 9745mm, with wide operation coverage. The super climbing capacity of 70% (35°) is suitable for complex terrain. Equipped with Kawasaki full electronic control hydraulic system, combined with Sany HOPE full electronic control technology and new hydraulic circuit, it realizes intelligent matching of engine-pump-valve, reduces fuel consumption by 5%-10% in common gears, and its energy efficiency ratio is far higher than that of competitors in the same class. The dual variable main pump features low noise and high-pressure output, with smooth and precise compound actions. The travel speed is 5.6/3.5km/h and the swing speed is 11.5rpm, achieving high efficiency in both transfer and operation. The whole machine adopts heavy-duty reinforced design, with boom, arm, chassis frame resistant to impact and wear, and 51kPa low ground pressure improving ground adaptability; the cab is upgraded to create a "first-class cabin" driving experience in cooperation with a well-known automotive design company. The 10-inch high-definition intelligent large screen supports 4G network OTA upgrade and one-click call, the narrow armrest box and minimalist front control box optimize the operation space, and the full vehicle sealing design effectively isolates dust and noise. It is standard equipped with multiple safety configurations such as rear camera and hydraulic pilot lock, fully meeting the EU ROPS safety requirements. The centralized maintenance point design makes daily maintenance more convenient. Coupled with Sany's perfect global service network and original parts supply, it provides a strong guarantee for the long-term stable attendance of the equipment, and is an optimal equipment for reducing costs and increasing efficiency in engineering construction.
