Excavator rock arm, eagle hook arm, hook arm, eagle hook, diamond arm, super hook modification

The company specializes in the production of excavator rock arms, excavator shortened arms, heavy rock big and small arms, hook-machine integrated arms, rock drilling arms, integrated hook rock arms, eagle hook modification and other names; tailored according to customer needs, The designed product has a dead weight of about 14-32 tons. It is an artifact for excavating weathered fossils and shale rocks. At present, these products are mostly used in the excavation of weathered fossils in the northwest region. Compared with traditional operations, the operation efficiency is high, the cost is low, and the environmental pollution is less. . Professional mining of weathered stone, shale, sandy limestone, fault rock, apatite, red sandstone, fluorite, syenite, etc., hard soil, coal mine and other engineering mining, effectively save time and improve crushing efficiency.

1. Hook machine integrated arm: The main change is the design of the forearm, from the old box-type welded rock arm to the current design of the integrated arm, which is mainly cut and formed from the overall steel plate to complete an integrated independent product without welding. The box is filled with iron sand. The weight of the forearm of different models is designed to be 8-22 tons, and the thickness of the plate is between 260-420. The boom is connected by box candles without counterweight iron sand. The working dead weight of the rock boom is designed to be between 6-10 according to different models. The thickness of the plate is between 30 and 50. The weight of the design product is determined by the size of the model. Due to the special setting of the modified product according to the hardness levels of different mines, in order to achieve the ideal impact crushing effect, the overall The integrated design of the excavator improves the overall product quality and changes the working efficiency. The main advantages of the excavator integrated arm are: extremely low failure rate, higher working efficiency, and 1.5-2 times faster than the integrated working efficiency. Create higher productivity for guests using the product.

2. Eagle Hook Arm, Diamond Arm:

As a special attachment of the excavator, the rock arm is a powerful tool for excavating and crushing weathered stone, shale rock, red sandstone, etc. It has the advantages of high efficiency and low loss compared with the traditional breaking hammer operation. In terms of high operating efficiency, low crushing cost and low maintenance cost.

The main structure of the rock arm is the huge olecranon-like forearm, so it is also called the olecranon arm. Compared with ordinary excavators, the boom is thicker and heavier to deal with stronger impact. The crushing principle of the rock arm is that under the gravity of the heavy arm and the arm, the sharp hook at the front end is used to violently break the rock.

Due to the harsh working environment, we use Q345B\Q550D material to choose from in the use of materials. The thickness of the material is not described in detail here. The material thickness of the rock arm is about 30-45 thick.

In the welding process, we carry out multi-layer stitch welding, and an internal buffer plate is installed in the arm to withstand the tension load. After the external welding process is completed, the inside of the large and small arms is poured into the iron sand cover plate for welding, and the internal structure of the box is solid. body, further ensuring the durability of the arm.

At the same time, according to the working conditions of the mine, the single hooks we configure are all reinforced rock single hooks, which can be indestructible. The design of the forearm cancels the general method of the connecting rod, so that the bucket cylinder directly drives the small hook, which is large and less powerful. The joints of the connecting rods are worn out, also known as super arm, diamond arm.

1. The rock arm modification of the hook machine does not change the performance of the original excavator

2. The modified model with hook rock arm is (36-120) tonnage excavator modified

3. The rock arm is changed to shorter arm box body welding, and the forearm solid welding process

4. The weight of the overall rock arm is about 14-32 tons

5. The confluence configuration of the middle cylinder of the hooking rock arm, the speed is fast and the strength is strong

6. The modified rock arm is powerful for rock breaking operation

7. Efficient work efficiency is 90-180 cubic meters per hour

8. Safe and efficient operation provides you with higher work efficiency

9. Welcome customers and friends to visit our company and negotiate business
