Abstract

A mobile light tower (1) comprising a base unit (2) and at least one light (4a, 4b) connected to the base unit by an extendable mast (5), the base unit including a power source for powering the at least one light, the extendable mast (5) adapted to move between a retracted position and an extended position, wherein the mobile light tower includes a controller (6) and a wind speed sensor (7), the controller adapted to lower the extendable mast to an intermediate position, between the retracted position and extended position, when the wind speed sensor (7) determines that a predetermined wind speed is exceeded.

Claims

1. A mobile light tower comprising a base unit and at least one light connected to the base unit by an extendable mast, the base unit including a power source for powering the at least one light, the extendable mast adapted to move between a retracted position and an extended position, wherein the mobile light tower includes a controller and a wind speed sensor, the controller adapted to lower the extendable mast to an intermediate position, between the retracted position and extended position, when the wind speed sensor determines that a first predetermined wind speed is exceeded.

2. The mobile light tower of claim 1, further comprising a light rig, the light rig comprising the at least one light and a mounting point between the at least one light and the extendable mast.

3. The mobile light tower of claim 1, wherein the extendable mast is telescopic.

4. The mobile light tower of claim 1, wherein the wind speed sensor is mounted on the extendable mast, distal the base unit.

5. The mobile light tower of claim 4 further comprising a light rig, the light rig comprising the at least one light and a mounting point between the at least one light and the extendable mast, and wherein the wind speed sensor is connected to the light rig.

6. The mobile light tower of claim 1, wherein the controller is adapted to lower the extendable mast from the intermediate position when the wind speed sensor determines a second predetermined wind speed is exceeded.

7. The mobile light tower of claim 6 wherein the second predetermined wind speed is the same as or higher than the first predetermined wind speed.

8. The mobile light tower of claim 1, wherein the intermediate position is determined based on the wind speed detected by the wind speed sensor.

9. The mobile light tower of claim 1, wherein the controller is arranged to determine that the first predetermined wind speed has been exceeded when the wind speed sensor detects a wind speed in excess of the first predetermined speed for a preset amount of time.

10. The mobile light tower of claim 1 further comprising an inclination sensor arranged to measure inclination of the base unit.

11. The mobile light tower of claim 10, wherein the controller is arranged to check whether or not the base unit is level before allowing the extendable mast to be raised.

12. The mobile light tower of claim 10, wherein the controller is adapted to lower the extendable mast when a change in the inclination is detected by the inclination sensor.

13. The mobile light tower of claim 1, wherein the base unit comprises a movement sensor to detect how much the wind acting on the light is affecting the base unit to determine whether to lower the extendable mast.

14. The mobile light tower of claim 2, wherein the light rig is arranged to reposition the at least one light depending on the height of the extendable mast.

15. A mobile light tower comprising a base unit and at least one light connected to the base unit by an extendable mast, the extendable mast adapted to move between a retracted position and an extended position, wherein the mobile light tower includes a controller, non-transitory memory, and a wind speed sensor, wherein the non-transitory memory contains instructions, that when executed by the controller, lower the extendable mast to an intermediate position, between a retracted position and a fully extended position, in response to an indication that a first predetermined wind speed is exceeded.

16. The mobile light tower of claim 15, wherein the non-transitory memory contains instructions, that when executed by the controller, lower the extendable mast from the intermediate position to the retracted position in response to an indication that a second predetermined wind speed is exceeded.

17. The mobile light tower of claim 15, wherein the non-transitory memory contains instructions, that when executed by the controller, prevent raising the extendable mast in response to an indication that the base unit is non-level.

18. The mobile light tower of claim 15, wherein the non-transitory memory contains instructions, that when executed by the controller, lower the extendable mast in response to an indication that the first predetermined wind speed is exceeded for a preset amount of time.

19. The mobile light tower of claim 15, wherein the non-transitory memory contains instructions, that when executed by the controller, lower the extendable mast in response to a change in inclination detected by an inclination sensor.

20. A mobile light tower comprising a base unit and at least one light connected to the base unit by an extendable mast, the extendable mast adapted to move between a retracted position and an extended position, wherein the mobile light tower includes a controller, non-transitory memory, and an inclination sensor, wherein the non-transitory memory contains instructions, that when executed by the controller, lower the extendable mast to an intermediate position, between a retracted position and a fully extended position, in response to a change in inclination detected by the inclination sensor.
