Advanced Breaking Technology
a. Leading heat treatment technology. Enhance the performance of heat resistance and abrasion resistance.
b. Low oil consumption design. Reduce the oil cylinder volume and lessen the fuel consumption under the condition of guaranteeing oil pressure invariable.
c. Machine durability design. The piston adopts ring oil passage design to reduce the obstruction, making piston cylinder body more durable; The resilience minimization design protects the machine to extend the working life.
d.Deck durability design. The naked deck adopts steel plate to decrease wear.
e. Oil seal durability design. The face increased pressure in the oil seal is designed to return oil passage, reduce oil seal pressure, and improve oil seal service life.
f. Lightweight design. Achieve the best match with excavators and loaders.
g. Low noise. In the city whose noise is limited, choose low-noise bracket breaker, which reduces noise effectively through the damping rubber cushion and seal box.
