DEVICE FOR GUIDING WORKING FRAME PROVIDED VERTICALLY MOVA BLE BETWEEN TWO SCAFFOLDINGS

摘要

PURPOSE: To prevent a working table from falling off by installing lower guide rolls at the end of the table and also an upper guide roll in proximity to an upper and a lower flange, putting the runner face for the rolls in contact with a guide rail, and dislocating the upper guide roll for a certain angle. CONSTITUTION: Lower guide rolls 10 and 11 are installed near a lower flange 4' at the end of a working table 4 and an upper guide roll 14 is installed near an upper flange 4" in such a way that the runner faces are contacting. The table 4 is precluded from swinging in the longitudinal direction and transverse direction by displacing the upper guide roll 14 for an angle of 90 degs. with respect to the lower guide rolls 10 and 11. The lower guide rolls 10 and 11 are arranged contacting in a pair to both sides mating of a guide rail 2. This removes swings of the working table 4 during the elevation and sink and immediately after it.
