INDUSTRIES

EHSG Hydraulic grapples are most commonly used in the dredging industry.

OPTIONS

EHSG Electro-Hydraulic grapples are available with a wide range of tine liner options to fit your individual scrap requirements.  The general rule of thumb is the narrower the tine, the better it will penetrate large scrape, the wider tines are used for shred and small scrap.  Semi-enclosed is the most popular style and comes standard.  Quick connect tines are available allowing for easy changing of tines to suit different materials and sizes.
