CEMEX Kinshofer C60HD re–handling clamshell
December 2014 – Materials giant CEMEX UK, one of the country's leading supplier of cement, ready mix concrete, mortars, and aggregates has continued expanding its modern fleet of plant with the purchase of a second new KINSHOFER C60HD-150 re–handling clamshell. The clamshell was delivered and installed by us.
The Heavy Duty clamshell, which has a 2.25 Cu M capacity, was specified with additional bolt-on horizontal and vertical wear blades to help reduce wear caused by material abrasion and a heavy duty 360 degree continuous rotation system. The clamshell was then fitted to the 'swan neck' dipper of a VOLVO EC360CL for the companies sand and gravel operations at its Attenborough Quarry, Beeston, near Nottingham.
The grab is used for unloading sand and gravel from barges and for discharging stockpiled material into a main feed hopper at the plant, and will handle approx. 1,200 tonnes of material per day.
Among the key features of the C60HD clamshell is the wide pitch PCD 'slew ring' type rotation device for increased strength and stability, the use of high strength impact resistant materials which contribute to a low overall weight of the grab and the 'flat bottom' closing curve which prevents damage to railway wagons, boats and lorries. Bolt-on reversible Horizontal and Vertical wear blades protect surfaces vulnerable to abrasion, but also ensure rapid down time when being turned or replaced. The grabs 'shells' are also keyed to ensure a sealed closure of the grab, preventing material from being dropped by the clamshell whilst in transit.
