On the support temporary connected to the rack the pointer of the said verticality is mounted. The pointer is made in the form of a flashlight with screw clamp electric (laser) from a battery, which is fixed by the bracket and the holder. Flashlight beam creates a light spot of small diameter on the screen of the marking plate for visual alarm on the achievement of the desired verticality of rack to the base. ^ EFFECT: claimed design ensures increased productivity when installing the main elements of the hot frame with the required accuracy of location of the racks, it enables with minimal effort to assemble all the elements of the hot frame. ^ 3 cl, 9 dwg |
