Hydraulic digging arm for mining
It was developed for bad working conditions where workers need the hydraulic digging equipment which could rotate big angle with long arms.
This equipment was fully controlled by hydraulic with the advantages of compact structure, and small size, which could save energy, be easily controlled and produce less pollution, at the same time achieve the all kinds of mechanized duties under the mine and increase efficiency.
Hydraulic digging arm contains scraper pan, pan arm, vice arm, arm, rotating seat, reversal seat, underpan, walking areas, and hydraulic control system.
After getting to the face by trance flat car, the hydraulic control system offers the energy to the vice arm.

Then the vice arm offers the energy to the pan arm, which connects the scraper pan to excavate
The rotating seat could rotate to left or right from the hydraulic cylinder.
The reversal seat could reverse a maximum of 70 degrees and connect the scraper pan, pan arm, vice arm, arm making the function of full cleaning achieved.
When the driving machine needs to walk, walking machine will stretch four lifting cylinders out, and lift the slider brace, drive the cylinder, drive the body forward or back, and the maximum of each step is 650mm, helping to achieve walking or moving.

FAQ:

1、Q: What is the main usage of hydraulic mining arm for excavation?
A: The most important function of hydraulic mining arm is to excavate and clear the bottom. It can realize the bottom cleaning work mechanically under the mine, instead of manual excavation 、bottom cleaning, and improve the working efficiency.
2、Q: What are the characteristics of hydraulic mining arms for excavation?
A: The device is compact, small in size, easy to enter the mine and high efficiency
3、Q: What is the difference between a mine hydraulic arm for excavation and other excavators?
A: The base can be rotated, and the maximum can be rotated 70 ° to the left and right respectively. It can achieve all-round excavation, bottom cleaning, and maintenance functions.
4、Q: What are the main structures of hydraulic mining arm for excavation?
A: Hydraulic mining arm for excavation is composed  of bucket, rod, secondary arm, main arm, rotating seat, turning seat, chassis, walking mechanism and hydraulic pressure control systems.

5、Q: What is the walking mechanism of the mining hydraulic arm for excavation?
A: Our company has developed a hydraulic mining arm for moving, when there is a need to move, start walking mechanism. To carry forward or back movement 0.65m each time to facilitate excavation or bottom cleaning

6、Q: What is the difference between hydraulic mining arms and other excavators?
A: Most excavators need to rely on tracks to walk, large size, difficult to enter the mine; The mine hydraulic mining arm is small in size and can be rotated, lie on the side, walk freely ,and can also use winch traction, more convenient and efficient
