JSB Features:

JSB SERIES hydraulic breakers are widely applied to rock broken, mining, road, building engineering, dismantling engineering and special engineering (underwater project, tunnel project), etc. Our major products are side type, top type and silenced type breaker.

Advanced Breaking Technology

a. Leading heat treatment technology. Heat resistance and abrasion resistance are enhanced.

b. Low oil consumption design. This reduces the oil cylinder volume and lessens the fuel consumption under the condition of guaranteeing oil pressure invariable.

c. High 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 and thus extends lifespan.

d. High deck durability design. The naked deck adopts high-intensity steel plate to decrease wear.

e. High 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 lifespan.

f. Lightweight design. Achieve the best match with excavators and loaders.

g. Low noise design. In cities limiting noise, low-noise bracket breakers are prefered which reduce noise effectively with damping rubber cushion and seal box.

Powerful Hydraulic System which Increases the Impact of Nitrogen

a. Superior performance. New hydraulic drive system for nitrogen provides a powerful blow crushing power; the maximum impact kinetic energy brings the highest production efficiency.

Long Lifespan which Reduces the Cost

a. Well-chosen alloy steel ensures a longer working life

b. High precision processing and excellent heat treatment technology make Jishan breaker more durable.

Simple, Convenient and Comfortable Operation, Easy Maintenance

a. Fine pipeline design and less block resistance make the operation more convenient and comfortable.

b. Precise and simplified structure is designed to improve reliability.

c. Simple structure ensures instant maintenance.
