Cable contractor ARM claims to have saved almost £1,500 in an 18-week trial by switching one of its skidsteers from pneumatic to puncture-proof AirBoss tyres.Punctures costing £30 each to repair were happening on average six times during the four-week life span of tyres costing £70 to repair.These costs no longer apply, thanks to the AirBoss system, and no crucial downtime is lost as the puncture-proof tyres have carried on working without needing repairs.Pat McGeoghan, ARM plant and transport manager, said: 'Speed is of the essence on an operation such as ours and running a large fleet of skidsteers on pneumatic tyres, we're bound to have a relatively high percentage of tyre failures.''When we were made aware of the AirBoss system I was keen to carry out comparison tests, as it seemed to be a practical solution to our tyre problems as well as producing a cost-saving bonus.'ARM was established 28 years ago in Lancashire and has seen turnover grow from £2 million in 1985 to an estimated £30 million this year.The company's policy of keeping costs to a minimum is underlined by administration director Roger England: 'As a large contractor employing a substantial workforce, operating an extensive fleet of machines, we continually monitor everything that involves a cost factor to the company.''Differences in margins are very small these days and profit can be lost through slack or bad management these days.'Since the test results were analysed, three ARM machines have been fitted with the system and the company will gradually replace all pneumatic skidsteer tyres with AirBoss.Mr McGeoghan has also encouraged plant hire companies supplying ARM to switch to AirBoss.
