The customer in the west of England required a vacuum system that could be used to handle stone dust and spent stone from the conveyors feeding and discharging three large stone crushers at the quarry.
The requirements for the vacuum unit were strict. The site maintenance team needed to be able to use the unit at night, and it needed to be sufficiently powerful to handle dust and stone chippings over a significant distance. It needed to be easily towed into position by tractor and capable of being easily reversed as some locations had access issues.
The solution was provided by a powerful, trailer-mounted vacuum unit that Portable Vacuum Solutions had just taken delivery of from Italy. This 75kw diesel unit featured a 6m³ tipper-based collection tank and ticked the all-important environmental boxes with its filtration system.
The only problem was that this unit had been designed to be towed to site by a truck fitted with a 5th wheel, not a farm-type tractor fitted with conventional towing ball. To solve this issue the trailer’s running gear was re-engineered and the towing method was changed within a 10-day period.
