Straddle carrier having a low-emission and low-maintenance turbine drive

摘要

A straddle carrier having an electric drive system, consisting of a lower and an upper frame, which are connected with one another by means of supports. A lifting mechanism with hoists is disposed on the upper frame, and the lower frame consists of chassis carriers having electrically driven wheels, and a power generation unit that feeds its generated electric power into a direct voltage intermediate circuit, to which current inverters for supplying the travel, lifting, and auxiliary motors are connected. The power generation unit represents a micro gas turbine having an attached power generator, the power of which is passed to the travel, lifting, and auxiliary motors. The straddle carrier can be produced at low weight and maintained under advantageous conditions. Furthermore, the straddle carrier can be operated under environmentally friendly conditions.
