Power and free conveyors consist of a double track, that is to say two runways made from suitably shaped sections welded to dedicated elements that hold them in the correct position. Combining straight track runs, horizontal and vertical curves and switches makes it possible to achieve the required layout.
The chain runs inside one runway and is fitted with pusher dogs; the load-carrying trolleys travel in the other runway. While the chain is kept permanently in motion, the trolleys are engaged with or disengaged from the chain by dedicated devices controlled by the conveyor management system. In this way the motion of each trolley can be adapted to the specific requirement of every single stage of the process.
The use of switches makes it possible to route the trolleys along different paths, while the ability to accumulate the load carriers, packing them closely together, allows storage banks or buffers to be created, considerably reducing the floor area occupied.
The working environment temperature can reach 240°C.
Power and free conveyors in the overhead version need to be suspended from an existing structure or from one built specifically for the purpose.
Our overhead power and free conveyors are suitable for carrying loads of up to 6000 kg, which can be increased to 12000 kg with suitable design measures.
