Novelty: a hoisting and transport mechanism practicable for construction works performed in cisterns and tunnels is disclosed. Function mode: the object is embraced and carried by rotation of the invented mechanism to the desired height while simultaneously retained by said mechanism in proximity to the placement point; construction process is facilitated to a great extent by the above mechanism moving on all the length of the tunnel and scanning this last step by step. Purpose: to shorten the duration of the positioning of the sheet iron (as depicted in figure) or other objects such as cables, lighting bodies etc; to assist the working staff in executing their work in an unhindered comfortable manner, reducing at the same time accidents hazards. Embodiment: the invention finds application to the mechanical and construction domain; it can be used for the hoisting and transport of objects, machinery, tools, workers and technicians to the worksite (cisterns or tunnels). |
