Take a trip with Canning Conveyor

Canning Conveyor have recently designed and supplied an extension to the existing tripping conveyor system at Tarmac Northern’s Cross Green works. Fairport Engineering, Tarmac Northern’s appointed managing contractor, worked closely with Canning Conveyor to ensure that this relatively small but vital part of the entire project was the most cost-effective solution to the key issue of increasing the plant’s ground storage capacity.

The Cross Green project has involved a major expansion to the facilities and products that Tarmac Northern are able to offer from their Leeds base. This includes the establishment of new dry mortar and concrete plants to complement the existing asphalt plant. In order to allow all three plants to be adequately fed with raw materials the existing covered store needed to be extended. Three additional storage bays were added to the original structure and the existing tripper conveyors were extended and uprated to suit this new arrangement.

The new conveyor system is capable of transporting 2,000 tonnes/h of imported aggregates and uses a 1,200mm wide belt running at 2.5m/s, thereby providing sufficient capacity for the plant for many years to come. By extending the conveyor by some 40m, the overall length of the tripper system is now over 140m, which necessitated the uprating of the drive to 90kW.

To support Fairport’s fast-track programme, Canning delivered the tripper extension to site in July 2003 after a design and manufacturing period of only 16 weeks. The extended system was successfully commissioned in August 2003 after an installation period of just two weeks. The early completion of the extended tripper system allowed Fairport to commission and hand over the entire project to Tarmac ahead of the agreed target date.
