Abstract: A lift device includes a lift apparatus for raising and lowering a robotic attachment. The lift apparatus includes a base assembly, the base assembly including a prime mover to rotate one or more wheels. The robotic attachment includes a base, a primary robotic implement, and a secondary robotic implement, each moveable independent of the base. The robotic attachment further includes a stabilizer bar coupled to the base and configured to engage with an external support to provide a stabilizing force to the robotic attachment. At least one of the primary robotic implement and the secondary robotic implement are configured to move one or more end effectors to perform a welding operation, including a weld gun, a weld lead, and a needle scaler. The lift apparatus may also include a control system configured to position the robotic implements in a plurality of preset positions.
