Title:
METAL CORE FOR CRAWLER, AND CRAWLER PAD WITH METAL CORE FITTED THERETO
Document Type and Number:
WIPO Patent Application WO/2020/179932
Kind Code:
A1
Abstract:
[Problem] To provide a metal core for a crawler, and a crawler pad, with which it is possible to prevent a pad main body becoming detached from the metal core. [Solution] Head portions of bolts 11 projecting from a shoe plate 2 are each covered by bulging portions 19 of a metal core 7, and a pad main body 8 is bonded to the road surface side thereof, that is, to the outside of the bulging portions 19, and therefore an interface between the pad main body 8 and the metal core 7 is not exposed in recessed portions comprising internal spaces 19a in the bulging portions 19 that accommodate the head portions of the bolts 11. There is therefore no risk of the metal core 7 and the pad main body 8 becoming detached, even if mud penetrates into the internal spaces 19a in the bulging portions 19 from the side of a joining surface joined the shoe plate 2.
