Considering the maximum impact power and efficiency, the HB series hammers are built. HB series hydraulic breakers are designed with an external control valve, and the control valve is mounted outside of the hammer with bolts tight on. Customers could maintain without dissembling the whole hammer to change the seal kits or repair the control valve. The bracket has two replaceable side covers, it tightened by high-level bolts. Changing the side covers when rock damaged it after a long time of usage, instead of spending the cost on the whole bracket.
CTHB HB series excavator breaker has a high and stable performance on quarry applications, it can easily handle construction works, demolition works, foundations tasks, etc.
CTHB has side type, top type (pin-mounted and cap-mounted), and box type bracket of HB series hammer for options. Pin-mounted top type is popular in the middle-east market and has very good performance under the local working environment.
‘Maximum breaking force and optimum durability/performance ratio for daily use.’
