The Hamilton Extra Heavy Duty (EHD) Series is the rigging platform for applications that punish the whole caster — not just heavy load, but impact, drop-loading, and continuous abuse. Up to 5,000 lb per caster, with heavier construction and kingpinless options for the toughest industrial routes.
EHD isn't just a higher number than heavy-duty — it's tougher construction for a tougher failure mode. Heavy-duty casters are sized for sustained load; the EHD platform is built for sustained load plus impact: drop-loading onto the cart, rough-floor hammering, dock-plate slams, the abuse that cracks lesser rigging. Heavier-gauge construction, kingpinless options, bearings rated for the punishment.
Stamping and forging operations where dies get dropped onto carts, foundry transfer over rough floors, tow-line trailers that take coupling shock, and any heavy route where the caster takes hits, not just weight. The EHD platform also carries the UltraGlide EHD wheel option when you need premium polyurethane on this tough rigging.
Heavy duty is sized for sustained load. EHD adds tougher construction for impact, drop-loading, and abuse — the failure mode that cracks lesser rigging.
Up to 5,000 lb per caster, with kingpinless options for the heaviest and most impact-prone applications.
