Abstract
A cover (1) for manholes or traps is described, equipped with a mechanism for lifting and horizontally translating the cover (1), the mechanism being actuated through actuating means (10, 11, 12), and being adapted to automatically lift and afterwards horizontally translate or rotate the cover (1) to which it is operatively connected in order to completely open the manhole or trap.
Claims11
A cover for manholes or traps for lifting and horizontally translating the cover a mechanism being actuated through actuating means and being adapted to automatically lift and afterwards horizontally translate or rotate the cover to which the mechanism is operatively connected in order to completely open the manhole or trap, wherein the mechanism is composed of a mobile frame for supporting the mobile cover fastened onto telescopic guides having a complete extraction, in turn fastened to a mobile lifting frame equipped with wheels, connected through a rack, to a gear with toothed wheels driven by a driving screw of a revolving type, an actuation of the driving screw, by means of a handle, lifting the mobile cover.

A cover for manholes or traps, equipped with a mechanism for lifting and horizontally translating the cover, the mechanism being actuated through actuating means, and being adapted to automatically lift and afterwards horizontally translate or rotate the cover to which the mechanism is operatively connected in order to completely open the manhole or trap, wherein the mechanism is composed of a frame for supporting the mobile cover fastened onto telescopic guides having a complete extraction, in turn fastened to a mobile lifting frame, equipped with wheels, connected through a cross member to an hydraulic jack placed inside a fixed frame whose actuation, by means of an external hydraulic pump, lifts the mobile cover.
A cover for manholes or traps, equipped with a mechanism for lifting and horizontally translating the cover, the mechanism being actuated through actuating means, and being adapted to automatically lift and afterwards horizontally translate or rotate the cover to which the mechanism is operatively connected in order to completely open the manhole or trap, wherein the mechanism is composed of a frame for supporting the mobile cover, fastened to a ring capable of performing a complete rotation around the vertical axis, and integral, by means of a pair of ball bearings with axial resistance, with a screw, whose rotation, controlled by an external handle, inside a threaded sleeve integral with the fixed frame, lifts the mobile cover and, when closing, through the recess, closes with pressure the cover onto the frame.
