CLAMSHELL BUCKETS WITH VERTICAL HYDRAULIC CYLINDER FOR HEAVY DUTY
≥ This extremely robust clamshell bucket with two vertical cylinders is ideal for heavy duty digging tasks in grown soil, for excavating earth and for underground constructions
≥ The two vertically positioned hydraulic cylinders are protected both by their position beside the body as well as by an additional piston rod protection
≥ Excellent digging performance due to the good plunge behaviour and the approved shell geometry
≥ Long service life is ensured through the use of 500 HB steel in the manufacture of cutting edges and the generously dimensioned bearing system
≥ Synchronised bucket movements due to the sturdy and forged compensation rods
≥ Bolt-on digging teeth are delivered with each clamshell bucket
≥ Excellent digging characteristics are the result of the high closing force of 32 kN 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
