Hamilton EPSD Enhanced Precision Series – Super Duty

Capacity Range: 2200 – 10,000 lbs.

Engineered for industrial performance, the Enhanced Precision Super Duty (EPSD) Series offers a powerful upgrade to the legacy PSD Series. Designed with balanced proportions and a rugged aesthetic, the EPSD bridges the gap between our Maxi-Duty (MD) and Extra Heavy Duty (EHD) caster lines—making it ideal for demanding applications that exceed standard load requirements but don’t require the full capacity of our heaviest-duty casters.

At the core of the EPSD’s performance is our advanced HPI™ Swivel Technology, delivering smoother swiveling, increased durability, and extended service life—far superior to conventional unit load bearing systems. This upgrade translates into less maintenance, better maneuverability, and dependable operation in high-impact environments such as manufacturing plants, aerospace tooling, and material handling systems.

The EPSD Series also features a redesigned top plate with slotted mounting holes, ensuring bolt-pattern compatibility with the former PSD Series as well as an additional industry-standard configuration. This dual-pattern design makes retrofitting easy and provides added versatility for OEMs and industrial engineers.

Key Benefits for Industrial Applications:

  • Heavy-duty caster design with balanced performance and aesthetics
  • Proprietary HPI™ Swivel Technology for enhanced maneuverability
  • Dual-pattern top plate for flexible mounting and retrofits
  • Ideal for factories, aerospace, assembly lines, and heavy equipment transport
