The equipment is consisted of a work machine, a holder, a moving mechanism, a power box and a control device. The invention uses an embedded steel pipe pile as a base to enable the wok machine to operate directly on the holder and to allow an expansion link on the work machine to extend or rotate in cooperation with a global positioning satellite system. The invention is quick in positioning and has strong mobility and flexibility. Furthermore, with GPS positioning system, it allows the constructor to grasp the location of the expansion link precisely while doing remote control.
