SAFETY LOCK FOR SCRAPER APRON

摘要

A safety lock is mounted on the apron of a wheel tractor or tractor drawn scraper for selectively holding the apron in a raised position. The safety lock comprises a pin member slidably mounted on the apron and normally retained in a retracted position during scraper operation. The apron may be raised and the member extended over a sidewall of the scraper bowl to positively maintain the apron in such raised position.
