Dust and Vibration Control with a difference

When asked to demonstrate power drills with low vibration at Ysbyty Glan Clwyd Hospital in North Wales, VJT naturally turned to the Makita range with AVT (Advanced Vibration Technology). However, when Jon Freeman, part of the VJT Technical Team, arrived on site it became apparent that the actual requirement was for a drilling machine that offered little vibration to the structure of the building itself.

As this was the refurbishment of a working hospital the primary need was for a drilling and fixing system that would not disturb dust in adjacent rooms and wards and would, at the same time, offer quiet and efficient overhead drilling. Working very closely with Makita [the power tool company] and Heller [the drill bit manufacturers] VJT tried many power tool/drill bit combinations in their test centre to produce a short list of suitable products.

The Makita HR1830 light rotary hammer with 6mm Heller Trijet SDS drill bits, and the Makita HP2071F percussion drill with 6mm Heller QuickBit Turbostone drill bits proved to be the best combinations.

When tested on site in various drill and fix situations both systems met the requirements of the client, Betsi Cadwaladr University Health Board. And now, Laing O’Rourke, the contractors, have a solution to the drilling problem and a solution for the fixing problem with the VJT TDN ceiling fixing and the VJT TSM M8/M10 threaded rod hanger.

The installation team were very impressed by the performance of the drills and the fixings and commented that the tools were “light and easy to use” and that the fixings were a “doddle to install”.
