GREASE FEEDER USING WORKING PRESSURE OF A HEAVY EQUIPMENT DIFFER-STICK DEVICE CAPABLE OF PREVENTING ABRASION OF A SLIDING UNIT BY AUTOMATIC SUPPLY OF GREASE

摘要

PURPOSE: A grease feeder using working pressure of a heavy equipment differ-stick device is provided to extend the life in use by preventing the damage caused by abrasion of a sliding unit and to promote the convenience on operation by supplying grease to a sliding unit of an operating device automatically. CONSTITUTION: The grease feeder using working pressure of a heavy equipment differ-stick device comprises: a grease storage container(101) connected to a sliding unit(100) of an operating device such as a boom, an arm, etc. of heavy equipment to store up grease; a primary valve(103) connected to a hydraulic cylinder(102) driving an operating device to generate and change loading pressure preset in a hydraulic cylinder(102); and a secondary valve(105) installed on a supply passage(104) between the sliding unit(100) and the grease storage container(101) and opening a supply passage(104) when the primary valve(103) is changed, to supply the grease discharged from the grease storage container(101) to the sliding unit(100) automatically.
