COUNTERWEIGHT OF CONSTRUCTION EQUIPMENT MOUNTING LIFTING STRUCTURE

摘要

PURPOSE: A counter weight for construction equipment with a lifting structure is provided to lift in a stable state where the center of gravity is balanced while lifting the counter weight to mount on or separate from the rear side of construction equipment such as an excavator, and prevent mutual interference with adjacent parts of a section on which the counter weight is mounted. CONSTITUTION: A counter weight for construction equipment with a lifting structure includes a housing groove(11), a lifting structure(12), and a stopper fixing pin(14). The housing groove is formed on the top of a counter weight(10) on which the center of the gravity is located in the top edge or the outside of the top. The lifting structure is coupled to be slid along the housing groove. In case the lifting structure is projected toward top of the counter weight along the housing groove in order to lift the counter weight, the position of a lifting point is moved on a same axis with the center of the gravity of the counter weight. The stopper fixing pin is embedded in a guide groove(13) of the lifting structure to prevent the lifting structure secession from the housing groove.
