HYDRAULIC FLUID COOLING APPARATUS OF A HYDRAULIC MOUNTING DEVICE FOR AN OVERHEAD TRAVELING CRANE, CAPABLE OF PREVENTING THE ABRASION OF HYDRAULIC MACHINES AND HYDRAULIC LINES DUE TO THE INCREASED TEMPERATURE OF HYDRAULIC FLUID

摘要

PURPOSE: A hydraulic fluid cooling apparatus of a hydraulic mounting device for an overhead traveling crane is provided to effectively prevent the abrasion of hydraulic lines and hydraulic machines due to the viscosity degradation of the hydraulic fluid since the temperature of the hydraulic fluid increases because the hydraulic fluid is cooled between a hydraulic cylinder and an oil tank.;CONSTITUTION: A hydraulic fluid cooling apparatus of a hydraulic mounting device for an overhead traveling crane comprises an installation frame(2), a motor, a cooling fan, an oil tank(5), a hydraulic cylinder(6), and a temperature sensor. The installation frame is installed between a bracket(B) and a main body(M) of a hydraulic mounting device(T) mounted on a girder of an overhead traveling crane, and has multiple intake holes(1). The cooling fan and multiple heat exchange pipes are installed inside the installation frame. The heat exchange pipes cool the hydraulic fluid by heat exchanging with outdoor air flowing from the cooling fan. The temperature sensor detects the temperature of the hydraulic fluid.;COPYRIGHT KIPO 2012
