CLAMSHELL BUCKETS WITH HORIZONTAL HYDRAULIC CYLINDER HEAVY DUTY

≥ The rugged clamshell bucket is a successful composition of design, function and performance

≥ Maximum loading height is achieved through the compact design with the horizontal hydraulic cylinder

≥ All bearing bushes are made of a high-strength bronze alloy with lubrication pockets to secure the emergency running properties

≥ A special V-section sealing ring prevents the ingress of water and dirt

≥ Long service life is ensured through the use of 500 HB steel in the manufacture of the cutting edges and a generously dimensioned bearing system

≥ Synchronised opening and closing through the unique compensating mechanism as well as the cylinder protection

≥ Bolt-on digging teeth are delivered with each clamshell bucket

≥ Excellent digging characteristics are the result of a high closing force of 30kN at 260 bar operating pressure

ACCESSORIESFOR CLAMSHELL BUCKETS

≥ The scraper is for clamshell buckets with narrow widths

≥ During opening the scraper clears the inside of the shells of sticky materials such as clay

≥ The design varies depending on the shape of the grapple

≥ The adapter enables the mounting of compression rails or the support for concrete rings for handling paving slabs, curbstones, concrete rings, etc.

≥ The adapter can only be used with a non-return valve, simultaneous usage with a scraper is not possible

≥ The central lifting device for the HPXdrive, welded eyes or welded hooks serve for lifting chains or slings

≥ The maximum capacity per eye or hook is 1000 kg

≥ The wear plates serve to protect the horizontal cutting edges
