The experience gained from many years’ involvement in the blasting industry has been incorporated into the design of the Protoblast trolleys.
Heavy wall S.H.S. members are arranged to shed abrasive, minimising blow-down time after blasting. Wheels are of impact-resistent S.G. iron.
The large diameter wheel bearings are protected by cover plates, and wipers ahead of each wheel clear the rails of abrasive as the trolley rolls.
