随车吊 crane truck

随车吊 也叫折叠吊 通过将大臂折叠起来节省空间，有便于建立在移动平台上工作。 我用了斯堪尼亚做演示，可以看到未展开的本体占用空间极小。 配备了多种的勾爪配合使用

操作方式：

A---向左旋转 D---向右旋转 w---第一节抬起 S---第一节降低 1---第二节抬起 2---第二节降低 3---第三节抬起 4---第三节降低 5---大臂伸缩全出 6---小臂伸出 7---小臂收回

（已集成电路拿出即可使用）

Truck mounted crane, also called folding crane, saves space by folding up the boom, and is convenient for working on a mobile platform. I used Scania for demonstration, and you can see that the unfolded body takes up very little space. It is equipped with a variety of hooks for use

Operation method:

A---rotate to the left

D---rotate to the right

w---lift the first section

S---lower the first section

1---lift the second section

2---lower the second section

3---lift the third section

4---lower the third section

5---extend the boom to the full extent

6---extend the forearm

7---retract the forearm

(It can be used after the integrated circuit is taken out)
