Saving time for greasing!
About TOKU Auto Grease System
3.5m -Utilizing hydraulic high-pressure oil from base machine, TOKU Auto Grease
System automatically supplies appropriate amount of grease to hydraulic
breakers during breaker operation.
3m
Reducing the running cost of hydraulic breakers!
Benefit of TOKU Auto Grease System
-By supplying appropriate grease to the breaker all the time during breaker
2.5m operation, the wear of most consumable parts such as chisel bushing and
retainer pins could be minimized, which extends lifetime of spare parts and
reduces hydraulic breakers running cost.
