Abstract

PURPOSE: To facilitate a tensioning operation of a wheel member by providing on an oil passageway between a grease filling cylinder and a grease supplying cylinder with an opening-and-closing valve and enabling to supply grease into the grease filling cylinder by an operation of the opening-and-closing valve and an operation driving a dozer device and the like to a predetermined position.
CONSTITUTION: A crawler tensioning system is constituted so that a wheel member 11 for tensioning the crawler may be slided along a track frame 12, and is provided with a grease filling cylinder 16 and a grease supplying cylinder 22 fitted within a return tube 18 continuously attached to a cylinder tube 15 for the cylinder 16. Here, a grease chamber 20 is communicated with a cylinder chamber 13 through a grease oil passageway 23 and an operating oil supplying passageway 24 for an operation chamber 21 is connected to a hydraulic circuit of a cylinder 7 for a dozer device. An opening-and-closing valve 28, comprising a non-return valve 30 integral with a connecting metal 29 for connecting a grease pump for filling grease into the grease chamber 20, is interposed in the grease oil passageway 23.
