Product Description

Features
The forearm is cut from the whole piece of high-strength manganese steel, which reduces welding and processing, and the cost is lower.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.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 strengthThe 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 armThe structure of the soil ripper and the connecting rod of the rotating shaft is canceled so that the maintenance is more convenient, the failure rate is lower, and the driver is more relaxed.
