More Information
Summary:A folding light tower is provided that utilizes a 4-bar linkage mechanism which enables full vertical extension of the tower with the use of one actuator. The exemplary tower generally includes a base, a lower lift arm, and an upper lift arm. Spring elements are used near the rotating joints of the lower lift arm and upper lift arm of the tower. The spring elements act to preload the joints and help to remove play and movement when the tower is unfolded/during the vertical extension process.
