Tiedou's Recommended Excavators (Issue 11) Recommended 30-60 ton hot excavators from Sany Heavy Industry

​​​​​​​　　Excavators over 30 tons are very challenging for the manufacturer's technology and craftsmanship, but from the perspective of material selection, large-tonnage excavators have high load pressure and equipment wear and tear, and they have to bear more equipment losses than small excavators. In terms of power selection, the equipment needs sufficient output and more reliable engine quality. The hydraulic system bears greater pressure, which also means that large excavators have higher gold content. Secondly, the excavator's walking system and core components such as rotation and multi-way valves have more stringent requirements.

　　The engines of Sany Heavy Industry's large crawler excavators are basically Isuzu, considering the popularity and reliability of Isuzu. The manufacturer fully considers this point. The performance improvement brought by the 365H excavator equipped with Kawasaki hydraulic pump from the basic 212cc to 240cc is very obvious. The Sany 485H and 550H series large excavators are mainly aimed at corporate users. Individual purchases of this level are also used on large construction sites. Tiedou can provide comprehensive modification services for these excavators, and reduce the cost of use by installing various accessories or modifying the excavator models appropriately for different types of work. Tiedou modification passes the inspection and is customized, manufactured, and installed by the manufacturer's dedicated personnel to ensure the practicality of the accessories.
