Trolleys And Carriers

Maximum Strength and Easy to Operate

Acco Trolley

A trolley is one of the basic elements of monorail and crane equipment. Long life and dependable service are absolutely essential. All parts of the trolley, including wheels, bearings, yokes, loadbars and swivel fittings have been designed and constructed from proven materials to meet the most exacting requirements. Designed for maximum strength and ease of operation, our trolleys are built to carry the specified weight and to move the load with a minimum of effort. Since trolleys in most monorail and crane systems must withstand hard, rugged service, Louden® trolleys have been engineered for durability under a wide range of operating conditions.

Flanged Wheels

Trolley with flanged wheels for use with special loadbars, racks and carriers.

Flangless Wheels

For smooth travel on tighter radius curves.

Increased Loading

Standard Patented Track Carriers come with up to 8 wheels to increase the allowable load. Customizable options with additional wheels are available upon request.

TROLLEY - FEATURES
  • Trolley yokes are one (1) piece cold formed steel
  • Precision ball or tapered roller bearings mating wheel with high strength axle
  • Utilizes flat tread wheels turned from forged steel blanks with induction hardened tread and flanges
  • Has a minimum hardness of 425 Brinnell
  • Bolt through the side of the yoke
  • All trolleys are fully articulating
  • Standard engineered loadbar, with properly spaced trolleys
  • Bronze wheels available on some units
  • Trolleys equipped with external grease fittings
  • Flangeless wheels with guide rollers available
  • Standard engineered load fittings available
TROLLEY - BENEFITS
  • Structural and dimensional integrity, resulting in a consistently high quality component
  • Easy horizontal movement of trolley along track, adds longevity to components
  • Long wearing tread and flange for exceptionally long service life, with minimum rolling friction
  • Contains loadbar in trolley, and is easily removed thereby simplifying erection of the system
  • Equalizes load to both sides of rail, minimizing unit stresses, resulting in longer life of track Definite plus over “Kingpin” type. Additionally, trolleys guide smoothly around curves and through switches and latches in monorail systems
  • Equalizes wheel load along track for reduced unit stresses (as above), plus protecting trolleys from damage with rugged bumpers
  • For applications where atmospheres dictate the use of spark-resistant components
  • Enables refreshing lubricant to be added as required on systems with severe duty cycle
  • Reduces track wear on systems with severe duty cycle or a large number of curves and switches
  • Swiveling clevis, hooks, or eyes may be specified for attaching a wide variety of loads to the trolley
