Abstract:
PROBLEM TO BE SOLVED: To provide a foreign matter preventive net capable of being easily loaded just in front of a heat exchanger of a small rotary type hydraulic shovel, in which the opening part of a machine chamber is narrow even when a cover is taken off.
SOLUTION: A foreign matter preventive net 30 for catching suspended matter which tends to enter fin parts of an oil cooler 20 and a radiator 21 is made up of two sets of net-divided bodies 30' combined in parallel. The first net-divided body 30' is inserted from the opening part of a machine chamber, moved in the direction of a cab, and fixed by screwing a thumbscrew 34 into a female screw 20a on the cab side on the upper part of the oil cooler 20. Then, the other net-divided body 30' is inserted with its end face being in contact with the end face of the first net-divided body 30', and then fixed by screwing a thumbscrew 34 into the other female screw 20a on the counterweight side on the upper part of the oil cooler 20, and thus the foreign matter protection net 30 is loaded into the oil cooler.
