AGV lifting equipment can be operated manually to ascend and descend. Operator can run it through manual operation box or footswitch at the two sides of the lifting equipment. After AGV enters into assembly path and track the body, operator opens the lock equipment of slide flat and uses lifting manual control box to operate lifting equipment. After assembly, press the completion button, the lifting equipment will automatically return to its initial position. Then operator locks the slide flat. Each lifting equipment is installed with a coder, which can make feedback on the lifting position. Lifting height, including altitude to be lifted and maximum height can also be set through software.
