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 and rock arm: mainly the design change of the small arm, from the old box type welded rock arm to the current integrated arm, which 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 most 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、 Split single hook rock arm: due to the harsh working environment, we use Q345B \ Q550D as the optional material. I won't introduce the thickness of the material 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, for the operation of the mine, the single hook configured is a reinforced rock single hook, which can have an invincible effect.
