The company specializes in the production of excavator rock arm, excavator shortening arm, heavy rock arm, mine rock arm, rock drilling arm, single hook rock arm and Eagle hook modification. They are customized according to the needs of customers, with a total weight of about 14-30 tons. They are good assistants for excavating weathered rocks and shale rocks. At present, they are mostly used for excavating weathered rocks in Northwest China. Compared with traditional operations, they have high efficiency, low cost and less environmental pollution.

Excavator refitting short boom manufacturer, excavator refitting short boom and hawk arm, Carter excavator refitting short boom and single hook arm, short boom, hawk arm and single hook arm are also called rock arm, which are specialized in mining weathered rock, shale, hard soil, coal mine and other projects, saving time and improving efficiency.

1、 The integrated rock arm single hook is mainly a change in the design of the small arm, from the old box type welded rock arm to the current integrated design, which is mainly cut and formed from the integral steel plate to complete an integrated independent product without welding the box into iron sand. The weight of a single jib is designed to be between 8-14 tons, and the self weight of the product is designed according to the model. Because it is specially adapted for different mines to achieve the most ideal crushing effect, the overall design greatly improves the product quality, changes the working efficiency of use, and improves the operating efficiency of the scale to 1.5-2 times the speed. Create higher work efficiency for customers who use the products.

2、 Due to the harsh working environment of the split rock arm, we use Q345B \ Q550D materials. I won't introduce the thickness of the material in detail here. The 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 and feasibility of the arms. Provide one-year after-sales warranty service, so that you have no worries about after-sales and warranty.

At the same time, in view of this working condition, the scarifier we configure is a reinforced rock scarifier, which can have an invincible effect.
