Thick and hard! How powerful is the integrated hook arm?

[BONOVO]

Let me introduce to you how powerful the integrated hook arm is. Let me introduce to you that with the continuous development and innovation of technology, large-scale mechanical products such as industrial equipment are also constantly upgrading. Take the rock arm as an example. As a special attachment of the excavator, it is a sharp tool for excavating and crushing weathered rocks, shale, red sandstone, etc. It has the advantages of low efficiency and loss compared to traditional breaker operations. Compared with traditional blasting operations, it has high efficiency, low crushing cost and low maintenance cost.

The main structure of the rock arm is the huge eagle-like forearm, so it is also called the eagle-beak arm. Compared with ordinary excavators, the arm has been thickened and heavier to cope with stronger impact.

In recent years, an integrated rock arm has appeared. Compared with the traditional rock arm, this integrated design cancels the bucket cylinder, connects the forearm and the ripper into one, and makes the forearm form an integral arm.

The bucket cylinder and ripper of the traditional hook arm are cancelled, making the forearm an integrated excavation and loosening device; reducing maintenance costs, reducing failure rates, and improving work efficiency. Under good working conditions, the excavation depth can be increased from tens of centimeters of traditional hook machines to nearly two meters.

Lower maintenance cost and higher cost performance

The forearm is cut from a whole piece of high-strength manganese steel, which reduces welding and processing and has a lower cost. The arm no longer uses a solid arm, but a hollow reinforced arm, which is lighter and reduces the overall performance loss of the excavator. The structure such as the ripper and the shaft connecting rod is cancelled, and the plate thickness reaches 30 cm, which can adapt to more severe working conditions without quality problems, maintenance is easier, the failure rate is lower, and the service life of the rock arm is increased, and the driver is more relaxed.

Comparison between the integrated hook machine arm and the traditional rock arm:

1. First of all, from the structural point of view, the old rock arm only adds the weight of the excavator arm and the forearm itself, adjusts the proportion of each part, and does not make large-scale changes; while the integrated arm cancels the bucket cylinder, connects the forearm and the ripper as one, and directly changes the operation method. From the structural point of view, the old rock arm has one more action and is more flexible. However, in actual operation, the old rock arm bucket cylinder only plays a supporting role and does not increase the digging force. On the contrary, due to the structural limitations of the ripper, the depth is limited when digging high-hardness rocks, and the ripper is more likely to break.
