• The contract for the removal of 70,000 tons of rocks from quarries in Lancashire and North Wales to the £40m Seaforth dock construction site in Liverpool, has been recently won by Chris Miller Ltd, of Preston.
The rocks, which are to be used for the main sea wall and weigh between 4 and 15 tons each, cause problems to the haulier because of their jagged edges, great concentration of weight, awkward loading, and the very bad ground conditions at the site.
The contract is comparatively short, lasting about nine months, and for this reason the company is using seven secondhand Atkinson tractive units powered by Gardner 6LX engines.
Each vehicle runs 24-hours a day with three shifts of drivers and one day is reserved each week for maintenance. A mobile workshop is situated at Seaforth which carries out minor repairs. Between them the vehicles transport 2500 tons each week while each vehicle covers about 10,000 miles every month.
At the Seaforth site, where conditions are exceptionally rough, an old written-off tractive unit is used to haul the trailers for final unloading.
