Tight Radius System (TR31)
Tight Radius System (TR31)

Work Securely and Safely

The Tight Radius rail and trolley system is designed to work as a moveable anchorage point for fall restraint applications.

Rails are composed of straight and curved sections that change direction in both horizontal and vertical planes, allowing trolleys to run exceptionally smoothly around very tight radii and joints.

The system is independently tested and is compliant with EN795.2012 Type D, meets ANSI Z359 and is OHSA compliant.

How Does it Work?

The TR31 continuous rail and trolley system allows a fully-harnessed crew member, safely tethered to the trolley, to move freely along the rail during inspection and maintenance, or when assisting in pilot transfer.

Rails can be either surface or stanchion mounted and are designed so the user never has to unhook and rehook the tether as he moves around the deck.

Logo-R27LongspanLong-Span Version of Classic R27 Access Rail System 

Harken Industrial developed the Long-Span Access Rail (R27LS) as an alternative to its flagship R27 Classic Access Rail system. The R27LS system offers the same strong, free-rolling ball bearing trolleys as the classic, but has a more robust profile, allowing it to handle longer spans without compromising strength.

Support brackets are offered in a variety of styles for ease of installation, and for mounting on surfaces of different types and configurations. Like the Classic Access Rail system, the R27LS can be used for fall protection and for rope access.

Available standard in clear-anodized. A wide range of optional specialty colors are available via request/special order. Please contact Harken Industrial for further details.

Engineered for Diverse Applications

The R27LS is used as a horizontal rail system in many fields (industrial, architectural, civil, etc.) to create a rigid mobile anchor for fall protection and rope access systems.




Longer Span Reduces Cost

The longer span between attachment points reduces installation costs: 3 m (9.84′) span for fall protection; 1.5 m (4.90′) for rope access.

High-Beam Rail

Choose high-beam rail for spanning unsupported spaces.

end-stops

Endstops

Endstops absorb shock loads and prevent the trolley from coming off the rail.

Ideal for Moving Heavy Loads

Harken Industrial rail systems can be used in a wide range of applications, including:

  • Construction
  • Renewable energy
  • Facilities management
  • Vessel maintenance
  • Material handling
  • Film production
  • Architectural
  • Utilities, oil & gas
  • Exercise
  • Transportation

Curved Rail 

Rails can be bent to suit a variety of applications.

Minor bends can often be made when the rail is installed. If the rail requires more bend, Harken Industrial can provide horizontal, vertical, or compound curves to specification.

The trolley’s length must suit the track radius to carry the correct load and perform smoothly. If the load requires a long trolley, but the radius is too tight, consider using two short trolleys joined by a coupler.

Below are the profiles of the four sizes of rails.

Torlon® vs. Delrin® Ball Bearings

Torlon® ball bearings are designed to cope with abrasion, dirt, and salt, and offer higher performance than Delrin® ball bearings. The balls have good elasticity so do not suffer permanent deformation until 70% of break load.

control-systems

Control Systems

Use for 2:1 to 6:1 purchases. Control blocks let trolleys instantly adjust and release under load. Assemblies secure to the rail, eliminating additional holes.

pinstop


Pinstop

The pinstop feature allows free movement along the rail when open. Closing it locks the trolley in position.

coupler

Couplers

As the size of a trolley increases so does friction. For higher load assemblies, a coupler can be used to join two trolleys together to spread the load.

Adjustable Seat Rail System
Adjustable Seat Rail System

A BETTER RAIL SYSTEM FOR SEAT MOUNTING

This system is specifically designed for the marine environment, giving you a flexible cockpit layout with fast, hassle-free reconfiguration. These systems meet HSC regulations.

How Does it Work? 

Seats are mounted on four trolleys that run on parallel rails. Two of the trolleys have pinstops that fit into the holes in the rails. Two trolleys are free sliding. To adjust the trolley location, simply raise the two pinstops and slide to a new location.

Trolley Design

  • Strong – tested to over 20 kN (25 kN for the 27mm rail)
  • Adaptable – can be fitted to dive tank racks, weapons racks, deck boxes etc.
  • Compact – minimum intrusion on cockpit sole
  • Black hardcoat-anodized; maximum corrosion resistance

Rail Design

  • High strength 6061-T6 aluminum low-profile rail
  • Hardcoat-anodized for maximum protection
  • Pinstop holes for maximum flexibility in seat spacing
  • Countersunk fasteners for flush fitting
  • Underside of rail recess for mastic sealant

Installation and Maintenance

Flush clean with fresh water and mild detergent. To reduce friction further, use McLube® high-performance dry lubricant. Do not use oils or greases. For added protection against corrosion, Harken Industrial recommends using Tef-Gel® corrosion eliminator on the fasteners when installing the rail.

The Shock Mitigation Seat Rail System should only be installed by a competent person or organization in order to meet the requirements of HSC regulations.

All rails listed are designed to use stainless steel fasteners. Attachment to the vessel must be in accordance with HSC regulations. Harken Industrial does not recommend installing with aluminium fasteners. Use of non- stainless-steel fasteners is at the liability of the installer and must be designed to meet the requirements of HSC regulations.

Always use thread locking solution or locknuts. Precise rail alignment at joints is critical for smooth-running cars.
