Project Description
At G.W. Becker, Inc., we take pride in engineering custom overhead cranes built for challenging environments. This week, we successfully shipped and prepared for installation a 5-ton single girder bridge crane designed for a hazardous location.
This project showcases our expertise in manufacturing lifting solutions that meet strict industry regulations, including CMAA, ANSI/ASME, OSHA, and NEC standards. From design to delivery, we ensured that every component was built for safety, reliability, and efficiency in demanding conditions.
This top-running, single girder bridge crane is designed for Class I, Division 2, Groups C & D hazardous locations. With spark-resistant mechanical features, it enhances safety in environments where flammable vapors may be present.

Runway Electrification System
To power the crane, we provided a 117-foot festoon electrification system ensuring smooth and reliable operation.
Inspection, Testing & Commissioning
This crane’s commissioning process includes:
- Electrical Wiring – Connecting the crane to power leads at runway elevation and ensuring all motors and controls are properly integrated.
- Structural, Mechanical & Electrical Inspection – Verifying compliance with OSHA 29CFR1910.179 and other safety regulations.
- Load Testing & Certification – Conducting a full-load test using weights transported by G.W. Becker, Inc. and providing certified documentation for compliance.
Ensuring Safe & Efficient Crane Operations
From hazardous location compliance to custom engineering solutions, this project is a testament to our commitment to providing safe, reliable, and high-performing lifting systems.
