Excavator rock arm, Eagle hook arm, hook arm, Eagle hook, King Kong arm, super hook modification Tel.: 134, 5068, 4096, wechat same No.: 134, 5068, 4096

The company specializes in the production of rock arm of excavator, shortened arm of excavator, large and small arm of heavy rock, integrated arm of hook machine, rock drilling arm, integrated hook rock arm, Eagle hook modification and other different terms; Customized according to the needs of customers, the designed product has a self weight of about 14-32 tons. It is the artifact of excavating weathered fossils and shale rocks. At present, such products are mostly used in the excavation of weathered rocks in Northwest China. Compared with traditional operations, they have high efficiency, low cost and less environmental pollution. Professional excavation of weathered rock, shale, sandy limestone, fault rock, apatite, red sandstone, fluorite, syenite, hard soil, coal mine and other engineering mining, effectively saving time and improving crushing efficiency.

1、 Hook machine integrated arm: it is mainly the design change of the small arm, which is changed from the old box type welded rock arm to the current integrated arm. It is mainly cut and formed from the whole steel plate to complete an integrated independent product, without welding the box to load iron sand. The weight of the jib of different models is designed to be 8-22 tons \ the thickness of the plate is 260-420. The jib is connected by box candle without counterweight iron sand. According to the working weight of the rock jib of different models, the weight of the product is designed to be between 6-10 and the thickness of the plate is between 30-50. The weight of the product is designed according to different models. Because the modified products are specially designed for different levels of rock hardness in different mines, so as to achieve the ideal impact crushing effect, With the integral design, the overall product quality is improved and the working efficiency is changed. The main advantages of the excavator integrated arm are: extremely low failure rate, higher working efficiency, and improved working efficiency to 1.5-2 times speed. Create higher work efficiency for customers who use the products.

2、 Eagle hook arm and diamond arm:

As a special accessory of excavator, rock arm is a sharp tool for excavating and crushing weathered rock, shale rock and red sandstone. It has the advantages of high efficiency and low loss compared with traditional crushing hammer operation. Compared with traditional blasting operation, it has high operation efficiency, low crushing cost and low maintenance cost.

The main structure of the rock arm is the huge beak like forearm, so it is also called the beak arm. Compared with ordinary excavator, the boom is thickened and weighted to cope with stronger impact. The crushing principle of the rock arm is that under the gravity of the heavy big and small arms, the sharp hook at the front end is used to violently crush the rock, with a devastating efficiency.

Due to the harsh working environment, we use Q345B \ Q550D materials for the use of materials. I won't introduce the thickness of the materials in detail here. The material thickness of the rock arm is about 30-45 thick

In terms of welding treatment, we carry out multi-layer overlap welding. Internal buffer plates are installed in the arms to bear tension loads. After our external welding processing is completed, we pour iron sand into the large and small arms to seal the cover plates for welding. The internal structure of the box is a solid body, which further ensures the durability of the arms.

At the same time, the single hook we configured for mine operation is a reinforced rock single hook, which can have an invincible magic effect. The design of the jib cancels the connecting rod assembly mode, so that the bucket cylinder directly drives the small hook, which has a large force and reduces the joint wear of the connecting rod. It is also known as super arm and diamond arm.
