Part of a procurement package of some forty Volvo loading shovels and excavators by CEMEX UK, during 2007 included a thirty six tonne EC360CL for its sand and gravel operations at their Attenborough Quarry, Beeston, near Nottingham.
Replacing a ten year old competitive model the new Volvo EC360CL underwent significant modifications to meet a dedicated application at Attenborough Quarry unloading sand and gravel from barges and discharging into the main feed hopper to the plant. This involved modifying and straightening the monobloc boom to a length of 6.8 metres and the manufacture of a 3 metre grab arm with under-slung dipper cylinder. A Kinshofer C60 2.25m³ clamshell grab complete with rotation and a load capacity of 4.5 tonnes has been fitted along with an additional counterweight. To facilitate good operator visibility of the barge unloading operation, the machine has benefited from a hydraulically adjustable cab giving a line of sight of 4.5 metres from ground level. The modifications to the cab and equipment have been undertaken by Messrs Kokurek of Ipswich.
In its new configuration the machine can easily handle a full grab of material weighing 4.5 tonnes to a discharge height of 4.3 metres and a reach of 6 metres from machine centre. At the other end of the working envelope the machine can extract material to a depth of 8 metres. In total the EC360CL will handle approximately 1200 tonnes of material per day from barges floated up to the plant from the quarry’s extraction area. After a period of one hundred years of extraction at the Attenborough facility, utilising barges on what are now man made lakes and lagoons, proves to be the most cost effective way of transporting the aggregate to the production area. When not unloading barges, the machine keeps the feed hopper topped up from a surge pile within its working envelope on the wharf.
The EC360CL is powered by a 12 litre Volvo Tier III low emission engine developing 250 net hp. Coupled to the innovative “Integrated work mode control” hydraulic system the machine delivers high productivity, high digging capacity precision and above all excellent fuel economy. The machine has been supplied with a full safety package including rear view camera, all round heated mirror visibility package, hand rails to the upper superstructure and warning chevrons painted on the counterweight.
