Radio Controlled Single Line Clamshell Buckets
Hawco radio controlled single line clamshell buckets are designed for use with single hook cranes such as ship's gear type cranes. Hawco's patented unique design possesses the most digging forces available in a single line type clamshell bucket, therefore enabling stevedores the ability to handle dense material such as iron ore or bauxite without having to resort to using electro-hydraulic grabs.
