Abstract
Urządzenie ma dwa segmenty, z których każdy jest zbudowany z teleskopowej, trójelementowej spągnicy (1) i podpartej dwoma stojakami (3) hydraulicznymi, teleskopowej trójelementowej stropnicy (2). Każdy ze stojaków (3) jest osadzony w gnieździe, stanowiącym urządzenie do blokowania końcówki takiego stojaka (3). Tylne i środkowe elementy stropnic (2) oraz spągnic (1) obu segmentów są ze sobą połączone za pomocą siłowników (6) hydraulicznych, osadzonych w uchwytach (7) tych elementów.The device has two segments, each of which is built of a telescopic three-piece floor (1) and supported by two hydraulic stands (3), a telescopic three-piece girder (2). Each of the stands (3) is embedded in a socket which is a device for blocking the end of such a stand (3). The rear and middle elements of the girders (2) and cogs (1) of both segments are connected with each other by means of hydraulic cylinders (6), mounted in the holders (7) of these elements.
