Rock Scoops
 
Rock Scoops
 
• Heat-treated alloy steel combines light weight with rugged strength.
• Pins and shafts are heat-treated steel of adequate size to prevent breakage and promote long service life.
• Handles like a dragline bucket but keeps the hardware above the rock.
• The weight, balance and hitch are all carefully designed for maximum production and minimum maintenance.
• Multiple hitch points are provided in order that the balance of the scoop is adjustable for differences in grade and/or application.
