applications. Straight rails can be bent to accommodate directional changes up to a 350 mm radius. Machined
corners up to 200 mm radius bends are available for both horizontal and vertical transitions.
TROLLEY DESIGN
• Strong: tested to 1200 kg (2645 lb)
• Complies with 2x MCA requirements
• Compact: minimum intrusion on narrow
deck and restricted work areas
• Multidirectional load bearing
• Anodized for maximum
corrosion resistance
RAIL DESIGN
• Vertical and horizontal
operating planes
• 1.3 m unsupported span
• High-strength, marine grade
6061-T6 aluminum rail
• Anodized for maximum protection
• Countersunk M10 fasteners
for flush fitting
BRAKE TROLLEY DESIGN
• Screwpin on trolley keeps it in
position when not in use
DELRIN®ROLLERS
• No lubrication required
• Low friction
• Smooth movement
• Roller fully supported on both ends
TIGHT RADIUS SYSTEM
The Tight Radius rail and trolley system
can be used for fall restraint. It is
independently tested and CE certified
under EN795.2012 Type D, meets

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.
INSTALLATION AND MAINTENANCE
The system can be installed either at initial build or as a
retrofit. Flush clean with fresh water and mild detergent.
It is important to clean the trolley. Excessive build-up of
grease, dirt, and salt will affect trolley movement.
