A robotic PV module installation system for populating a solar generation plant with PV modules with minimal human intervention. The PV module installation system can include an aerial work platform (AWP), a linear slide, and a robotic arm. The AWP can include an articulated boom. The AWP can also be configured for movement over off-road terrain. The linear slide can be coupled to a free-end of the articulated boom. The robotic arm can be coupled to a slide of the linear slide to increase a horizontal reach of the robotic arm through movement of the slide along the linear slide. The robotic arm can also include an end of arm tooling configured to pick up PV modules.

Disclosed embodiments include pan assemblies for aerial work platforms, methods of attaching a pan assembly to an aerial work platform, and methods of fabricating a pan assembly for an aerial work platform. In an illustrative embodiment given by way of non-limiting example, a non-limiting, illustrative pan assembly for an aerial work platform includes a pan configured to be disposed about a lower portion of a basket of an aerial work platform. A plurality of attachment mechanisms are disposed about an exterior of the pan, the plurality of attachment mechanisms being configured to removably attach the pan to a lower portion of a basket of an aerial work platform. A tensioning system is disposed within an interior of the pan, the tensioning system being configured to cooperate with the plurality of attachment mechanisms to hold the pan onto a lower portion of a basket of an aerial work platform.

A tilting support or work bucket, or apparatus for an aerial lift including a support frame for supporting an operator. The support frame can have a seat for supporting the operator when in an upright position and a chest support having a portion above and forward of the seat for supporting a chest of the operator when in a forwardly downward tilted position while allowing arms of the operator to extend forwardly out of the support frame. A support member can be pivotably mounted to the support frame at a pivot joint that is located at an upper portion of the support frame when the support frame is in the upright position, for pivotably supporting the support frame. An actuator can be included for positionably rotating the support frame relative to the support member about the pivot joint between the upright position and the forwardly downward tilted position. Since the pivot joint is located in the upper portion of the support frame, pivoting of the support frame from the upright position to the forwardly downward tilted position moves a center of gravity of the support frame rearwardly in the direction of the support member.

A battery powered lighting device is configured to be attached to a lift bucket having sidewalls and an upper lip extending from uppermost portions of the sidewalls. The lighting device includes a main housing, a securing member, and a main light mounted to the main housing and located to illuminate areas outside of the lift bucket. The main housing includes a first securing surface includes a pair of planar portions spaced from each other by a concave portion. The planar portions are configured to engage a planar surface of a sidewall or the upper lip of the lift bucket. The concave portion is configured to engage a convex surface of a sidewall or the upper lip located at a corner of the lift bucket.

A battery powered lighting device is configured to be attached to lift bucket having sidewalls and an upper lip extending from uppermost portions of the sidewalls. The lighting device includes a main housing, a securing member, and a main light mounted to the main housing and located to illuminate areas outside of the lift bucket.
