Enhanced Maxi-Duty Casters

Capacity Range: 28,000 - 40,000 lbs.

  • Swivel Construction 
5/8" thick drop forged steel mounting plate (rigid plate 1/2" thick) joined with a 1" thick swivel base; 3/4" thick plate steel legs are continuously welded inside and outside the 1" thick swivel base.
  • Kingpin 
1 1/4" diameter integrally forged with mounting plate guaranteed for life, prevents bending or breaking; threaded for special 1 1/4" combined CRS thrust spacer & slotted nut secured by roll pin for positive locking.
  • Main Load Bearing 
HPI™ thrust ball bearing with a 7" diameter rated to a comfortable 100,000 lbs.
  • Secondary Load Bearing 
1 1/4" extra heavy precision tapered thrust bearing counteracts radial thrust.
  • Axle
1 1/2" diameter turned, ground, and polished with slotted nut and cotter pin. 1 1/4" diameter on 8" wheels.
  • Lubrication Fittings
Ball-check type in swivel assembly and in wheel hubs.
  • Brakes
Keep safety manager happy with a dual heavy duty face contact brake (-DHCB) for more positive locking. Select desired caster from selection table to see brake details.
  • Swivel Lock
4 Position (-4SL)- convert swivel to rigid for straight line steering, robotically welded housing & CNC-milled slots assure long lasting, trouble-free performance.
  • Sealed Swivel Assembly
(-SS) - prolongs caster life in harsh environments.
  • Wheel Bearing Seals
(-DS) - prolong wheel life in harsh environments.
  • Custom Engineering
Hamilton engineers will custom design any caster to meet customer requirements.
 
For those applications when you need more than 23,000 lbs. and forged steel wheels will work for your application, look no further than the new Enhanced Maxi-Duty Caster Series.

The new EMD Series is a hybrid of our long-time Maxi-Duty Series and our new Ultra Maxi-Duty Series. The new series incorporate the smaller mounting plate of the Maxi-Duty with the massive swivel construction of the UMD Series. The result is a less costly caster than the UMD yet with ample bulk to handle loads up to 40,000 lbs. The dual forged steel wheels are machined with a slight crown to enhance rollability and swiveling.
Hamilton Precision and Durability
The enhanced Enhanced Maxi-Duty Wheel Series now features Hamilton’s Precision Integrated HPI™ Swivel Technology. This new technology outperforms conventional CNC-machined ball raceways, kingpinless, and unit load bearing swivel constructions. The new design improves the bearing’s element of contact and more than doubles the number of contact points. The new HPI™ raceways are also 45% harder than conventional hardened raceways and the surface finish is an incredibly smooth 16 micro inches.

 

The Enhanced Maxi-Duty Series (EMD2) is backed by Hamilton’s Three Year Product Warranty. Refer to selection table for qualifying wheels.
