摘要

Rolling device with blocking support, of the type comprising a fork (1) with two arms (11) parallel downwards and with an upper coupling (12), advantageously related by means of a ball bearing to allow its self-orientation, in both arms (11) being holes (13) facing horizontally for the freely rotating arrangement of a wheel (2), coupled axially by an axis (3) between said holes (13), the wheel (2) comprising in its perimeter surrounding projections (21) alternating with slots, and enabling the entry into the grooves of a conveyor belt or escalator, presenting coupled to the arms (11) of the fork (1) lateral supports (4), which are formed by a plate in a substantially vertical arrangement, with an intermediate fixing hole (41) on the shaft (3) and a lower support (42), this lower support (42) remaining in an inoperative arrangement. Perante without contact with the ground, established by the wheel (2), but in an operational arrangement on a conveyor belt or escalator makes contact by said lower support (42), defining the blocking of the displacement of the device, characterized in that each arm (11) of the fork (1) comprises in its upper part a punched recess (14) defining at least one transverse window, and the support (4) has prolonged at least one appendix (43) at its upper end, housed at through the window of said punched recess (14), for the attachment of the support (4) to the arm (11) together with the fixing hole (41) of the intermediate axial axis (3).
