Steel and iron boom

The proven machine frame adopts the best technologies and designs, realizing the force and durability needed by larger construction machinery. Even in the most demanding construction site, the robust excavators can stand the tests.

. First-grade start power The advanced NEO system and the large cylinder combine to bring unmatched start force.  . Strength and robustness The material and thickness of the boom and the arm get improved remarkably. The built-in dead block can bear the strain load Every component of the cross section has been redesigned with the service life increased by 30%. . Heavy-duty application For the HD models, the structure components, HD top frame and double guard are standard. In addition, the FOPS Level 2 engine head guard and the whole wheelbase guard are optional.

. Heavy-duty bucket Besides the standard bucket with large side shield, the HD model has a quarry bucket. The new HD bucket resists impact and wear, ensuring long-term performance.  . EMS brings long service life of pin and pin bush The special Sumitomo EMS has been widely used on the structure joints. The galvanized pin installed in the brass pin bush ensures that the two high stress points are durable. In this way, the lubrication interval is extended to 6 months. The pin surface adopts hard brass and the inside is of multi-layer solid grease, avoiding wear of parts. The pin surface is galvanized and the rigidity is increased, avoiding wear of parts. The particular dual dirt-sealing structure prevents the dirt from entering, avoiding wear. The section on the joint of the boom and the arm adopts the EMS of SH300.
