Trolley and Rail Systems

LOW-FRICTION LINEAR MOVEMENT                    Trolley Information  Rail Information

Harken trolley and rail systems provide a simple low-maintenance way to move loads smoothly. Trolleys feature recirculating ball bearings housed in strong, lightweight, corrosion-resistant aluminum for dependable, low-friction linear travel.


Low friction, smooth rolling
Harken rails and trolleys provide a low-friction rolling solution under both compression and tension loads.

Torlon® or Delrin® ball bearings reduce friction to move loads easily, and require no lubrication. Wire retaining clips and composite corner keepers keep ball bearings captive, allowing trolleys to be easily removed for maintenance.

Harken trolleys are designed with an open-ball race for easy maintenance. The rail can be bent to various radiuses, allowing the trolley to run freely.


Curved rail
Rails can be bent to suit various applications. Minor bends can be made when the rail is installed.

If the rail requires greater bend, Harken can provide horizontal, vertical, or compound curves to specification.

Contact Harken for more details.

Harken trolleys are available in a variety of sizes and configurations.

Q: Can Harken trolley and rail systems be fitted retroactively?
A. Yes. The simplicity of the systems means they can be easily installed at a later date.

Q: Are Harken trolley and rail systems able to accommodate a radius?
A: Yes. Trolley and rail systems can accommodate a radius bend. Contact Harken for information.

Q: Are Harken trolley and rail systems suitable for human suspension?
A: No. Only 27 mm and 32 mm Access Rail systems are certified. Please see Access Rail pages for further information.

Q: What other benefits are there to Harken trolley and rail systems?
A: Harken strong, lightweight trolleys and rails are specifically designed to resist the corrosive effects of an outdoor environment. Wire retaining clips and composite corner keepers hold ball bearings captive when the trolley is removed from the rail. An open-ball race makes trolleys easy to clean with soap and water.
