Abstract

An industrial truck comprises a plurality of wheels, each wheel comprising a hub and a cushion tire mounted thereon. The truck further comprises a sensor adapted to measure a temperature of a tread of one of the cushion tires and a control unit communicably coupled with the sensor and with at least one of a drive unit of the truck and a cooling unit associated with the tread.

Claims

1. An industrial truck comprising

a plurality of wheels, each wheel comprising a hub and a cushion tire mounted thereon;

a sensor adapted to measure a temperature of a tread of one of the cushion tires; and

a control unit communicably coupled with the sensor and with at least one of a drive unit of the truck and a cooling unit associated with the tread.

2. The industrial truck according to claim 1, wherein each wheel further comprises at least one tread part covering the cushion tire.

3. The industrial truck according to claim 1, wherein the sensor is adapted to measure the temperature of the tread without direct contact with the wheel.

4. The industrial truck according to claim 1, wherein at least one sensor is directed towards at least one tread.

5. The industrial truck according to claim 1, wherein the sensor comprises an infrared sensor.

6. The industrial truck according to claim 1, wherein the cooling unit is adapted to direct a fluid stream onto the tread.

7. The industrial truck according to claim 1, wherein the fluid stream comprises a stream of water.

8. The industrial truck according to claim 1, wherein the fluid stream comprises an air stream.

9. The industrial truck according to claim 6, wherein the cooling unit comprises one of a water sprayer, an air blower, or a fan.

11. The process according to claim 8, wherein initiating one or more measures includes reducing the angular velocity of at least one wheel.

12. The process according to claim 8, wherein initiating one or more measures includes directing an external fluid stream toward the tread.

10. A process for reducing the wear of the treads of an industrial truck, the truck having a plurality of wheels, each wheel comprising a hub and a cushion tire mounted thereon, the process comprising:

measuring a temperature of a tread of one of the cushion tires with a sensor;

transmitting signals from the sensor to a control unit, the control unit being communicable coupled with at least one of a drive unit of the vehicle and a cooling unit associated with the tread; and

initiating one or more measures, via the control unit, for reducing the temperature of the tread in response to the signals.
