LIEBHERR VERZAHNTECHNIK
The drag frame belts are designed for disc-shaped parts such as gear wheels, hubs and rings. The workpieces are dragged by a frame connected to a chain. The parts are transported either directly on the transport belt or indirectly using workpiece supports. Prism-shaped holders mean that exchangeable parts are not normally needed. At the transfer point for loading a machine, the workpiece is positioned using a servo system centrally under the loading/unloading point. Technical data:Workpiece weight [kg]: max. 70Conveyor length [m]: max. 20Transport capacity [kg]: 1,200Propulsion: Servo MotorTransport Speed [m/min]: 9Workpiece Diameter (standarad) [mm]: 30 - 380
