Born from a logistics need in the production of dough, it has the duty to lift and discharge wheeled bowls at pre-set heights from min. m 2,2 to max m 3,8. We wanted a device able to discharge at variable and remarkable heights but without too big dimensions for an easy transport, installation and room rationalization. As a matter of fact its dimensions, when the machine is closed, do not overpass 2,2 m, therefore it is suitable for trucks, containers and so on. The principle is simple: a standard structure of an elevator trolley with a maximum load of 2500 kg, a well-tried and reliable element. A discharging structure with double, perfectly balanced pistons has been made; the whole device is mounted on a stand with support and fixing legs suitable to the lifter. Inside the support a largely dimensioned hydraulic control unit is located for a continuous use. On completion of the security systems, the area where the trolley operates is protected by a ring that delimits the space under the bowl itself. It is possible, on demand, to close it in a box with a safety gate to delimit the zone of potential danger. Maximum lifting weight 800 kg.
