Computer-controlled hydraulic equipment for removal of building structure

摘要

The hydraulic jacks (2) set up at points of contact (3) with a building to be moved are supplied from their own hydraulic motors (4) connected to control units (6,7) on a common data bus line (8) from the computer (9). A displacement sensor (5) is provided at each point of contact and wired to the corresponding control unit. Either of these can operate as a master unit having direct connection to the computer, with a printer (11) for easy following of the movement. Interchange of master and slave functions is possible by means of a code plug or switch.
