Hydraulic Breaker
• Boasts the most powerful impact energy in this class of breakers, with little recoil.
• Advanced structure with reduced number of parts saves maintenance cost.
• The BPM(Blows per minute) can be varied with an optionally available device (JKHB 2000).
Large Power
Long stroke : Large impact energy, with little recoil, is attained by an increased piston stroke which allows the piston speed to increase through the relatively long acceleration path. Combined hydraulic-and-nitrogen gas pressure system : Makes the best use of the combination of the energy from the nitrogen gas enclosed in the back head and the energy of the hydraulic oil delivered by the hydraulic pump. (All Models except for JKHB 51)
Rigid Bracket
The breaker bracket, made of specially wear-resistant material holds the front head and rear head rigidly. Non-accumulator Mechanism Incorporating Advanced Technology. The conventional mechanism has been replaced by an improvement in valve timing, piston configuration and the combined hydraulic-and-nitrogen gas pressure system. (JKHB 801, 401, 301, 101, 71)
Fewest Parts Among Breakers on the Market
