Product Description
Excavator Attachments Excavator Hammer Rock Breaker Hydraulic Breaking Hammer
Hydraulic breakers can more effectively break stones and rocks in
engineering construction, improve work efficiency, and are suitable
for mining, metallurgy,railways, highways, construction ship
repairing and other occasions.
The advantages of silent crushing hammer
Reduce noise
Protect the environment
Strong and powerful "hydraulic+nitrogen"impact system
The most important characteristics of the breaking hammer are the
striking frequency and energy. Each model of DOPRO crushers has a
"strong and powerful impact power system of hydraulic + nitrogen".
The system has the advantages of high efficiency, less energy loss
and maximum impact energy. The breaking hammer of DOPRO can provide
strong impact energy.
Impact energy enhanced structural design
DOPRO crushing hammers adopt the most scientific and excellent
design concept, increase the stroke of piston and cylinder body,
and make the matching efficiency of crushing hammer and main engine
the highest.
Flow adjustable device
The device can effectively adjust the flow from the excavator or
power source, so as to adjust the required striking force and
striking frequency according to the rock conditions. According to
the rock hardness, the impact frequency is adjusted. The impact
force is large, the speed is slow, the impact force is small, and
the speed is fast.

Made with high quality materials and special precision technology
Strict selection of high-quality raw materials, special precision
process manufacturing, to ensure sealing, strong impact and
explosive force; Dopro crushing hammer high-quality and efficient,
durable.
