Underdeck Gantry Design & Installation

Spencer Bridge Engineering has unrivalled experience in the design, supply, installation and commissioning of permanent moving underdeck gantries on major crossings. Our team deliver innovative and efficient access solutions on complex structures within challenging environments, right from concept design to handover and ongoing maintenance.

We work collaboratively with our clients to understand the requirements of the access on each bridge asset, and engineer a bespoke gantry to suit the particular constraints and geometries. Moving gantries are a complex safety critical integration of structural, mechanical and control system disciplines, often requiring long operational design lives and robust maintenance strategies. Spencer Bridge Engineering are industry leading in this field and have provided some of the most complex systems in use today.

Our in-house design team of structural, mechanical and control system engineers, along with our technical project delivery team, provide a ‘one stop shop’ for all permanent gantry requirements. Our off-site and on-site teams have a proven ability to overcome the many challenges that arise when working on bridge structures in demanding environments, including working at height over waterways and within live operational and sensitive environments.
