抓木器分为：机械式抓木器，和回转式抓木器；机械式抓木器无需改装挖掘机管路及液压系统即可使用（低成本型）；回转式抓木器需要改装挖掘机管路和液压系统以达到360度回转的需求（方便，实用，高成本型）
The wood grabber can be pided into: mechanical grabber and rotary grabber; the mechanical grabber can be used without refitting the excavator pipeline and hydraulic system (low cost type); the rotary grabber needs refitting the excavator pipeline and hydraulic system to achieve 360 degree rotation (convenient, practical and high cost type)

抓木器安装
Installation of wood Grabber
（1）机械式挖掘机抓木器：采用挖掘机铲斗油缸推动，不用另外添加液压块及管路；
(1) Mechanical excavator grabber: driven by excavator bucket oil cylinder, without additional hydraulic block and pipeline;
（2）360°回转液压式挖掘机抓木器：需要在挖掘机上添加两套液压阀块及管路来控制；
(2) 360 ° rotary hydraulic excavator grabber: two sets of hydraulic valve blocks and pipelines need to be added to the excavator for control;
（3）不回转液压式挖掘机抓木器：需要在挖掘机上添加一套液压阀块及管路来控制。
(3) Non rotating hydraulic excavator grabber: need to add a set of hydraulic valve block and pipeline on the excavator to control.
