Excavator long reach fronts introduction
The classification of excavator's lengthened arm is as follows: (1) according to its operation mode, it is divided into building demolition and lengthening arm, deep pit and lengthening arm, pile driving and lengthening arm, etc. (2) According to the number of sections: two-stage lengthening arm, three-stage lengthening arm, four-stage lengthening arm, etc. (3) According to its performance, it can be divided into fixed lengthening arm, sliding lengthening arm and telescopic arm.
(1) The excavator's elongated arm is equipped with an internal buffer plate to withstand the tension load through computer stress analysis, material selection, process development, design and production. (2) The excavator's elongated arm is equipped with an internal buffer plate to ensure the structural strength, service performance and quality of the elongated arm, and prolong the service life of the excavator and the elongated arm. (3) The hydraulic steel pipe of the excavator and the extended arm is all acid-washed and phosphating, which ensures the cleaning of the hydraulic steel pipe of the extended arm and effectively prevents the rust slag and welding slag in the hydraulic steel pipe from entering the hydraulic pump and cylinder of the excavator.
