Claims18
A light tower comprising:
- a. a mobile trailer;
- b. a primary boom operatively mounted to the trailer and configured to pivot relative to the trailer;
- c. a pivoting means for pivoting the primary boom between a first transport position and a second operating position and a pivot controller configured to activate the pivoting means, wherein the primary boom has a base end and a distal end opposite the base end;
- d. a light section having an array of lights positioned proximate to the distal end of the primary boom, wherein the light section is operatively attached to a power source to operate the array of lights;
- and
- e. a stop limit switch positioned and configured to be triggered when the primary boom is pivoted into the second operating position, wherein triggering the stop limit switch is configured to deactivate the pivoting means.
3 more elements
A light tower comprising:
- a. a mobile trailer;
- b. a primary boom operatively mounted to the trailer and configured to pivot relative to the trailer;
- c. at least one extension boom connected to the primary boom, wherein the at least one extension boom has a base end and a distal end opposite the base end;
- d. a telescoping means for extending and retracting the at least one extension boom between a first retracted position and a second extended position system and a telescoping controller configured to activate the telescoping means;
- e. a light section comprising an array of lights positioned proximate to the distal end of the extension boom, wherein the light section is operatively attached to a power source to operate the array of lights;
- and
- f. an up limit switch positioned to be triggered when the at least one extension boom is extended into the second position;
- wherein triggering the up limit switch is configured to deactivate the telescoping means.
