To support the planned bridge replacement, the end customer required a solution to lift and position large concrete girders with precision and safety. SCOTT partnered with the contractor to provide a fully integrated hydraulic and control system designed to handle the job's complexity.
The Challenge
- Operate two gantry systems in sync—one at each end of the girder
- Enable remote, precise X and Y movement during placement
- Provide real-time feedback on engine performance
- Ensure smooth coordination between hydraulic and engine control systems
Our Solution | SCOTT delivered a turnkey system featuring:
- Two diesel hydraulic power units (HPUs) equipped with PVG32 proportional valves
- MC038-10 Plus+1® controller for managing logic and system functions
- IK3 wireless radio transmitter with dual receivers for remote operation
- MPCAN modules enabling CAN bus communication for control and feedback
With one transmitter, the operator can simultaneously control both lifting machines, including engine start/stop, throttle, and valve movement. The system also provides live engine feedback on fuel level, temperature, and battery status, ensuring safe and efficient operation.
The Result
Successfully tested and ready for deployment, this system played a key role in the timely completion of the I-40 bridge replacement. The customer is highly satisfied with the performance, reliability, and ease of use.
Why It Matters
Planned infrastructure updates, such as this one, keep our highways safe, efficient, and built to last. SCOTT is proud to support critical projects with the hydraulic and control expertise to make them a success.
The SCOTT team is grateful for the technical support and valued products from Poclain. Poclain is an independent industrial group specialized in the design, manufacture, and marketing of efficient hydrostatic and electrohydraulic transmissions headquartered in France.
Scott Industrial Systems announces the acquisition of Automated Engineered Solutions (AES), an automation company headquartered in Oberlin, Ohio. This marks a significant milestone in SCOTT’s continued growth, deepening its expertise in industrial automation, custom machinery, & advanced engineering solutions.
Pneumatics have played a crucial role in the evolution of aviation, dating back to the early 20th century. By the 1920s and 1930s, as aircraft design advanced rapidly, pneumatic systems emerged as a practical solution for enhancing performance and reliability, especially when weight was a critical factor.
When it comes to fluid power solutions, having the right certifications and capabilities can make all the difference. That's why at Scott Industrial Systems, we take immense pride in our Danfoss Certification and Build Center.
To achieve the precise range of speeds and torque required for heating rails, a combination of hydrostatic drive and mechanical linkage systems was deployed. This setup ensures sufficient power to move the system across the rails at controlled speeds, even on inclines.
In today’s fast-paced manufacturing world, automation plays a crucial role in improving efficiency and reducing manual labor. Jasper Engines & Transmissions, a leader in remanufacturing powertrain components, faced a challenge in optimizing the removal of lifter plungers from a family of internal combustion engines.
