般挖機使用在18-25噸左右，配上16米加長臂，大型挖機在30-45噸配24-28米加長臂，拆房作業時，只需剪斷幾根關建大梁就能使整棟房子倒塌，大大提高工作效益。液壓剪設計結構合理不易損壞，維修簡捷。
The general excavator is used at around 18-25 tons, equipped with a 16 meter extension arm, and the large excavator is equipped with a 24-28 meter extension arm at 30-45 tons. When demolishing a house, only a few building beams need to be cut to collapse the entire house, greatly improving work efficiency. The hydraulic shear is designed with a reasonable structure that is not easily damaged and easy to maintain.

Customized instructions:
一般情況下，挖掘機工作裝置部分包括動臂、斗桿、鏟斗以及相關的油缸和液壓管路。因挖掘機的工作裝置部分更換比較方便，所以可以根據不同的工作場合更換相應的工作裝置，以滿足各種工況的需要。例如整個工作裝置可以選用挖機加長臂(動臂、斗桿均加長，鏟斗容量減小)，這樣挖掘機的挖掘范圍增加了，挖機加長臂特別適合于一般河道的清淤；清淤時只需從河道兩邊的河灘上作業即可。工作強度大的礦山巖石挖掘需要選裝加強加厚的挖機加長臂以對付惡劣的工況，保證工程的順利完成?；蚝榭诠ぷ鞯臋C器有時要加裝吊鉤裝置以方便吊裝車輛。
In general, the working device of an excavator includes the boom, stick, bucket, and related oil cylinders and hydraulic pipelines. Due to the convenience of replacing the working device of the excavator, corresponding working devices can be replaced according to different working situations to meet the needs of various working conditions. For example, the entire working device can use an excavator with an extended arm (both the boom and bucket rod are extended, while the bucket capacity is reduced), which increases the excavation range of the excavator. The excavator with an extended arm is particularly suitable for dredging general rivers; When dredging, operations only need to be carried out from the riverbanks on both sides of the river. Rock excavation in mines with high work intensity requires the installation of reinforced and thickened excavators with extended arms to cope with harsh working conditions and ensure the smooth completion of the project. Sometimes, machines working at Hongkou need to be equipped with hook devices to facilitate the lifting of vehicles.
