Breaker Hammer VOLVO EC210 EC240 E26 Bob Excavator
DOPRO is a professional manufacturer committed to the design and
production of Hydraulic Breaker and Attachments Whether your job is
breaking down concrete surfaces, trenching, or preventing blockage
in crushing systems, DOPRO is made to withstand continuous breaking
in harsh environments. We DOPRO use only high quality low materials
to produce superior product and all the manufacturing process such
as heat treatment, forging, machining, grinding and ets, are
strictly controlled by qualitied and experienced engineers in our
factory with computerized and latest facilities. All parts are
thoroughly inspected at every time that each process such as
cutting, heat treatment, machining, grinding, cleaning, assembly,
etc. is carried out, and all inspection data per each production
lot are maintained and controlled so as to be utilized as data for
better qualities and performance improvement. Major parts such as
piston cylinder and etc are designed for outstanding durability
through structure analyses, and mass production is started only
when a proto type has been completely
Available from 0.8 tons of mini excavators to 60 tons of large
excavators
Advanced vibration absorber buffer system to reduce stress and
impact wave
Long durability with precise assembly
Box housing and vertical mounting type
High efficiency with optimized control valve system
High impact energy with the gas-hydraulic mechanism
Breaking hard-rock, reinforced concrete, and metallurgical slag
Main Features:
---Back head: Material: 20CrMo, impact energy is accumulated due to
charged nitrogen gas in the block.
---Front Head: Using 20CrMo material, high quality with long life
using.
---Valve: We adopt production process by grinding machine, with
high precision.
---Cylinder body: Material: 20CrMo, it is best quality material.
---Piston: Longer service life by optimized design and high quality
special steel.
---Front Head: Using 20CrMo raw material, which are provided by
domestic famous manufacturer, forging again and again to make
internal organization more tight and increasing the hydraulic
breaker wear-resistance.
