CTHB Hydraulic Breaker – Top Series
CTHB top-split type rock jack hammer has a semi-closed bracket design. The top-split head adaptor and two separated shells are assembled by bolts. Mainbody is tightened between the two shells by side bolts. The Semi-closed design offers a good operational view for the operator, which highly reduces the malfunction of the chisel. It is easy to check the status of hydraulic breakers, and easy to charge the N2 gas, maintain the accumulator, and connect the oil hoses.
The vertical cap-mounted design offers high-impact power when applied to vertical demolition, such as ground demolition, and cleaning the ladle arc refining furnace. The bracket is made of NM400 steel, we offer replaceable wear-resistant plates at the chisel side. The plates stand the most damage from the rock during breaking, customers will replace the plates instead of the whole shells after a long time using…..
“Capable of Crushing Any Type of Rock.”
