Ground conveyor, e.g. forklift truck has air stream cooling device whereby cooling air flow for cleaning the cooling device is reversible and reversal of cooling air flow is carried out as function of operating conditions of ground conveyor

摘要

The ground conveyor has air stream cooling device (3) whereby the cooling air flow for cleaning the cooling device is reversible. The reversal of the cooling air flow is timed and is carried out as a function of the operating conditions of the ground conveyor. A device is provided for the determination of the contamination of the cooling device.
