The Challenge:
In a high-stakes turbine motor overhaul center, the integrity of engine components is paramount. These turbines, utilized across demanding sectors like oil and gas, power generation, and military defense, arrive for refurbishment after extensive operational lifecycles. The overhaul process is meticulous. It requires complete disassembly and granular inspection of every part.
The primary operational bottleneck involved the material handling phase during reassembly. Operators were required to retrieve heavy turbine parts from vertical storage units, load them manually onto carts, and transport them to workstations. While an overhead crane was available, it proved fundamentally inadequate for this specific workflow. It was slow, bulky, and a shared resource for multiple work cells. This competition for access created a "waiting game" that caused significant delays and work stoppages. To circumvent these bottlenecks, workers frequently resorted to manual lifting. Larger components often required two-person teams. This created a high-risk environment. Back injuries emerged as the company's leading workers' compensation concern, alongside inefficient, disjointed work sequences.
The Solution:
To address these critical safety and efficiency issues, the facility adopted a Six Sigma manufacturing strategy and installed two 150-pound capacity Gorbel Free Standing Easy Arm® Intelligent Lifting Arms.
The Easy Arm® was the ideal choice because it integrates Gorbel's patented G-Force® intelligent lifting technology, a processor-controlled servo-drive system, into an articulating jib design. Unlike traditional hoists, the Easy Arm® provides the responsiveness of human movement combined with the power of an industrial machine. Its compact, free-standing footprint allowed for installation directly beneath the existing overhead crane. The system required no special foundation work on the facility's 6-inch concrete floor.
The Execution:
Implementation was seamless, largely due to the system's intuitive "plug-and-play" nature. As observed in the project workflow, the operator uses the Easy Arm® to precisely extract turbine components from the storage unit. The arm's articulating jib allows the operator to maneuver the load around obstacles and into the specific work bay with minimal physical effort. The "float mode" technology enables the operator to move the load naturally. It acts as an extension of their own arm. This transition from manual hauling to intelligent, servo-assisted positioning removed the reliance on the slow overhead crane and eliminated the need for two-person manual lifts.
The Result:
The facility's commitment to ergonomics and efficiency yielded immediate, measurable success. First, the primary safety objective was fully met. The facility recorded zero lost-time injuries and no back injuries since the implementation. Second, productivity increased by 25%. Eliminating wait times for the shared crane and streamlining the movement of parts into work bays increased overall throughput by a quarter. Finally, the workforce accepted the new system. The Manufacturing Manager noted that the system was easy to introduce. It fit into the existing Six Sigma workflow without the typical resistance associated with new equipment.
