30 Tons--CSJ300A


The advent of the CSJ300A series of pangolin all-in-one hook arm fills the gap of the 30-ton excavator's rock arm, giving full play to the advantages of the 30-ton excavator's fast speed, and giving full play to its maximum value under the working condition that the requirements for excavating force are not particularly high.


Weight: 15 T

Maximum digging depth: 1.8M
Product list: Big arm (including hydraulic pipeline), forearm, bucket rod cylinder

Advantages of the all-in-one rock arm:

Compared with the traditional rock arm, the all-in-one rock arm design eliminates the bucket oil cylinder and connects the forearm with the soil scraper to form an integral arm.

1. The forearm is cut from the whole piece of high-strength manganese steel, which reduces welding and processing, and the cost is lower.

2. The big arm no longer adopts the solid big arm, but adopts the hollow reinforced big arm, which reduces the weight and reduces the overall performance loss of the excavator.

3.The innovative design of integrated rock arm integrates the oil circuit of bucket oil cylinder and bucket rod oil cylinder into the pipe of bucket rod oil cylinder, which increases the overall flow rate of bucket rod oil cylinder, improves the strength of bucket rod oil cylinder, and increases the speed under certain conditions, without changing the hydraulic system of the excavator as a whole, resulting in lower loss and greater strength.

4.The plate thickness of the lower arm of the integrated rock arm is up to 30cm thick, which can adapt to more severe working conditions without quality problems and increase the service life of the rock arm.5. The structure of the soil ripper and the connecting rod of the rotating shaft is cancelled, so that the maintenance is more convenient, the failure rate is lower, and the driver is more relaxed.

Comprehensive strength
