The grip trolley type BR with its integrated push trolley is used as a helper for all kind of mounting, assembly and erection work.The system works with the same concept of our PTM trolley with the added bonus, that it can be moved from one beam to another by a simple and easy twist of the spindle. When it is installed on the next beam, a crowned counter nut locks the spindle. Any beam profile type like INP, HE and HE-B can be served. The mechanically machined steel rollers and the closed ball bearings are permanently lubricated. The spindle is protected against corrosion by zinc galvanization.
