Excavator rock arm is a reinforced working machinery equipment designed specifically for extreme working conditions such as hard rock fragmentation and mining.
50 tons is the main modified model, which can maximize the role of the rock arm and provide the highest efficiency.
The weight of the 50 ton split rock arm is 9 tons, and the boom cylinder weighs 900 kilograms.
The forearm weighs 9.5 tons, the bucket cylinder weighs 900 kilograms, and the rock ripper weighs 2 tons.
The bucket cylinder adopts 150-215mm cylinder, and the bucket adopts 140-200mm cylinder.
The bucket oil cylinder is directly subjected to force and experiences greater rebound force, requiring the use of a large oil cylinder.
Using a small oil cylinder not only lacks strength, but also increases the failure rate of the cylinder.
The interior of the rock arm box is filled with minerals such as diamond sand and iron sand, which have high density, small particles, and uniform distribution.
Uniform density can make the rock arm uniformly stressed and reduce failures.
The thickness of the upper and lower cover plates of the split type rock arm is 30mm, and the thickness of the upper and lower cover plates of the small arm is 30mm. The rock ripper motherboard adopts a thickness of 200mm.
Our board thickness is the thickest among peers.
Our main welding passes are all three or four layers of welding, with very high welding strength.
Split type rock arms are generally suitable for harsh environments, such as open-pit mines, quarries, and earthwork projects.
Mainly targeting weathered rocks, shale, sandstone, coal gangue, frozen soil, gravel, etc.
The single-sided design of the pipeline allows for visibility during operation, effectively avoiding collision risks, reducing usage risks, and saving maintenance costs.
The thickness of the forearm and rock ripper decreases gradually to reduce digging resistance.
