Tether Track Lifelines
Protect Your Workers Operating in Elevated Environments
Available in several mounting styles: Ceiling Mounted, Free Standing Monorail and Bridge Anchor Systems the Tether Track system is designed to be safer and more efficient than typical wire rope lifelines. Using a shock absorbing lanyard or self-retracting lifeline the worker is tied off directly overhead to reduce secondary fall injuries.
Engineered for OSHA and ANSI Standards
The Gorbel rigid rail lifeline systems are designed by qualified engineers to exceed the OSHA 1926 Subpart M Construction standard as well as ANSI Z359 Fall Protection Code using a maximum off-vertical loading of 30-degrees. This strict design criteria means that our track supports the full impact of falls vertically and also at a 30-degree angle. Thats important for applications where the risk is to fall off the side of an object rather than straight down.
Tether Track can be used in a variety of scenarios.
Train Yards
Protect workers who are elevated on the the tops of train rail cars. The Tether Track can be cantilevered over the edge of the track to create a safe working environment on top of the train. The rigid rail limits the fall distance if a fall would occur, reducing the chances of secondary fall injury.
Truck Loading Platforms
Protect workers who are elevated on top of a truck or loading platform. Our cantilevered system allows trucks to drive underneath a fall protection unit. Once underneath the crane, the worker can tie off to an anchor point that stays directly over their head and has no line sag. This keeps the worker on a mobile, yet "short leash" and allows them to work safely while mounted on a truck.
Bus Depots
Protect workers who are elevated on top of the bus doing maintenance and repairs. Ceiling mounted monorails and bridge cranes are a perfect match for bus garages where workers need to get on top of the bus for maintenance, cleaning and repairs. The monorail can be mounted to an existing structure or through a freestanding or fold away system.
Aircraft Maintenance
Protect workers who are elevated on top of an aircraft doing maintenance and repairs. Our bridge crane solution allows workers to be able to move on two axis. In this scenario, the bridge crane could be mounted to the ceiling of an aircraft hanger.

Tether Track Configurations
Ceiling Monorail
This involves mounting a rigid rail to the ceiling of a warehouse, hanger or other existing structure. The monorail can be dropped down to the appropriate height or mounted flush the ceiling. The monorail can support multiple tracks, allowing multiple workers to pass each other while tied off to the same rigid rail system.
Ceiling Bridge Crane
The bridge crane allows two axis of motion. This allows the worker complete mobility, moving on the x and y axis while keeping the fall protection anchor point directly over the worker's head.
Free standing Monorail
The free standing monorail can be supported in two ways. 1) It can be cantilevered from one side, such as in a rail car or trucking application. 2) Additionally it can be supported from two sides. The cantilever option requires the columns to be larger, while supporting it from two side requires smaller support columns.
Free Standing Bridge
The bridge crane allows two axis of motion. This allows the worker complete mobility, moving on the x and y axis while keeping the fall protection connector directly over the workers head. The freestanding unit is supported by columns on either side of the unit.
Choosing the Right Track
The following information is intended to assist you in choosing the best track for your application. ANSI defines one worker as an individual with tools that does not exceed 310 lbs. For applications that require a worker and tools exceeding 310 lbs, please consult us for a custom engineered system. All systems listed are designed for components that are rated for the industry standard 900 pounds maximum arresting force (MAF). MAF is defined as the shock force the body feels when decelerating from a fall. For applications with higher potential force, systems can be custom designed as high as the OSHA specified 1800 lbs MAF.
Plain Track
Plain enclosed steel track provides smooth motion with the benefit of offering the most headroom of any track style.
Trussed Track
Single trussed track allows for the longest possible spans between supports, reducing hardware and installation costs.
Dual Trussed Track
The dual-track enables one worker to pass by another on a monorail system without unsafely disconnecting.
Tether Trolleys™
Gorbel's Tether Trolleys were engineered specifically for fall protection applications to provide fluid movement and stability. The trolley uses DURACOMP4 wheels, a proprietary material that delivers unmatched durability and consistent long term performance. To match the 2-degree taper of the lower running flange, wheels are also tapered 2-degrees to help keep the trolley centered in the track for effortless movement.
The swivel eye secures the lanyard or SRL, allowing free movement beneath the trolley and prevents twisting of the lanyard or SRL.
The three wheel design of the monorail trolley prevents binding inside the track, even when side loaded up to 30- degrees. This means that as the workers moves, the trolley moves as well.
