The exclusive cab structure provides more foot space.
GRAMMER adjustable suspension seat is used in the excavator to adapt to uneven terrains.
The excavator cab is equipped with an openable roof hatch.
The inner surface of the hydraulic cylinder is treated through tumble finishing process to improve the surface roughness and hardness, therefore resulting in a greater wear resistance.
The piston rod is chrome and nickel-plated to prevent it get rusted while improving the abrasion resistance.
The excavator bucket adopts thickened steel plate, and the bucket teeth are strengthened and lengthened for greater wear resistance.
The strengthened box type structure is fully welded using low stress high tensile steel plate.
The high strength guard boards are installed as standard to protect the excavator components.
