The JM520 crawler excavator is designed with a durable and reinforced boom, a compact stick, a bucket, an extended heavy-duty chassis, and an optimized box-shaped structure. This configuration enables it to effectively adapt to diverse working environments, including highly challenging operational conditions.
The unique cabin design offers increased legroom for added comfort.
The excavator incorporates adjustable suspension seat, designed to accommodate varying terrains with uneven surfaces.
The cab of the excavator is outfitted with a roof hatch that can be opened.
The hydraulic cylinder’s inner surface undergoes a tumble finishing process to enhance both surface roughness and hardness. This treatment results in heightened wear resistance.
The piston rod is coated with chrome and nickel to prevent rust formation while also enhancing its ability to withstand abrasion.
The excavator’s bucket incorporates reinforced steel plates, and the bucket teeth are both strengthened and elongated to enhance their wear resistance.
The enhanced box-type structure is entirely welded using high-tensile steel plates with minimal stress levels.
High-strength protective panels are included as a standard feature to safeguard the excavator’s components.
