Construction Equipment with Excavation and Loading Function

Abstract

Disclosed is a construction equipment in which excavation and loading functions can be performed by one work equipment without any degradation of performance to remarkably reduce the expenses of the equipment and its size. The construction equipment having excavation and loading functions is constructed in such a manner that a work equipment comprised of at least one link member, the link member being connected by a hinge and provided with fixed pin holes, is provided at a predetermined position above a main equipment traveled by a crawler or a wheel, so as to be used as an excavator and a loader.
