Filed: 1998-12-16
Abstract: PURPOSE: A container for feeding oil is provided to feed oil to a proper position of an oil feed container in a tank by installing an oil feed valve and by preparing dependent oil feed units. CONSTITUTION: A support body(10) is installed by welding many support beams(11) in rectangular. A tank tub(30) having many compartments(31) is settled on a tank strut(20) in the support body. Subsidiary beams(13) are welded on both sides of the support body in the shape of an inverted triangle to prevent concentration of load of the tank tub to one side. A fork part of a forklift is inserted to an insertion hole(14) on one part of the support body to install an oil feed container in a container vehicle. A fitting part(12) on the lower part of the support body is combined to a fixing protrusion of the container vehicle to prevent displacement of the oil feed container. When oil in the oil feed container needs to be fed to another object to be fed with oil, a cap closing the end of a main discharge valve(44) is opened. An oil feed hose is connected to the main discharge valve. An operation valve on one part of the main discharge valve is opened to feed oil of a certain amount to the object to be fed with oil.
