发明名称 CONSTRUCTION OF AND TECHNIQUE FOR FASTENING WEAR SHOES TO A TRAWL DOOR
摘要 A wear shoe apparatus for protecting the bottom of a trawl door used to open a trawl being pulled behind a fishing boat. A lower wear shoe is provided with a bottom and two walls extending upward therefrom to define a channel sized to accommodate therein an upper wear shoe. Holes in the side walls are aligned with each other and with a corresponding hole in the upper wear shoe, with such holes permitting an elongated fastening member to pass therethrough for fastening the wear shoes to each other. The wear shoes are constructed of a very wear-resistant and durable material, such as manganese steel alloys. A mudshoe can be made an integral part of the lower wear shoe. Wear shoes and mudshoes can be installed, removed and replaced with greater ease and in less time.
