Title:
掘削ホイールシールド機構のためのオーバーロード保護機構
Document Type and Number:
Japanese Patent JP4043525
Kind Code:
B2
Abstract:
An overload protector mechanism provides protection for an excavating wheel shield mechanism so that if a large foreign object becomes lodged between the excavating wheel and a portion of the shield arrangement the shield mechanism can move out of the way and the wheel may be stopped. The overload protector mechanism includes a release mechanism connected between the shield mechanism and a wheel frame. The release mechanism includes a linkage arrangement having first and second links pivotally connected to one another and releasably biased to a set first position. Once the release mechanism trips, the shield mechanism pivots away from the wheel in order to prevent damage to the shield mechanism or to the excavating wheel and allow the wheel to be stopped and the large object removed.
