Vertical Rigid Track Systems

Rigid Track Ladder Lifeline Systems

Ascending and descending from ladders is a key safety issue in many different market sectors. From utility towers and wind turbines to fixed ladders found on silos and bulk storage towers, the use of a vertical rigid track lifeline system minimizes drop distance and forces exerted on a worker in the event of a fall.  In addition, a Vertical Rigid Track Fall Arrest System typically offers longer service life than a Vertical Lifeline constructed with steel cable, but it is important to discuss the length of the system and anticipated number of users with your fall protection company to make a sound decision on which style of fall arrest system will best suit your specific application.

Design Considerations

Vertical Rigid Track System Design Considerations For installations utilizing vertical rigid track systems, shuttle devices must run the length of the rail in an unhindered manner. Any snagging of the shuttle will make it difficult to move freely on the system and could pose safety issues.  While allowing freedom of movement up and down the length of the system, in the event of a fall, the shuttle must lock instantly to minimize fall distances and forces exerted on the user. Vertical Fall Arrest systems must be installed in a manner that does not restrict foot space on the ladder rungs or offer resistance as the user climbs or descends on the ladder  By offering a wide range of mounting brackets, the system can be configured to accomodate many ladder styles, including narrow gauge ladders where foot space is restricted. In applications requiring the use of a ladder where none is present, the rail is machined to accept ladder rungs, providing the dual benefit of fall protection while meeting the need to ascend and descend the system.

OSHA Regulations

  • OSHA Considerations
    • 1926.1053(a)(1)(iii) Each Fixed ladder: At least two loads of 250 pounds (114 kg) each, concentrated between any two consecutive attachments (the number and position of additional concentrated loads of 250 pounds (114 kg) each, determined from anticipated usage of the ladder, shall also be included), plus anticipated loads caused by ice buildup, winds, rigging, and impact loads resulting from the use of ladder safety devices. Each step or rung shall be capable of supporting a single concentrated load of a least 250 pounds (114 kg) applied in the middle of the step or rung. Ladders built in conformance with the applicable provisions of appendix A will be deemed to meet this requirement.
    • 1926.1053(a)(2) Ladder rungs, cleats, and steps shall be parallel, level, and uniformly spaced when the ladder is in position for use.
    • 1926.1053(a)(3)(i) Rungs, cleats, and steps of portable ladders (except as provided below) and fixed ladders (including individual-rung/step ladders) shall be spaced not less than 10 inches (25 cm) apart, nor more than 14 inches (36 cm) apart, as measured between center lines of the rungs, cleats and steps.
    • 1926.1053(a)(6)(i) The rungs and steps of fixed metal ladders manufactured after March 15, 1991, shall be corrugated, knurled, dimpled, coated with skid-resistant material, or otherwise treated to minimize slipping.
    • 1926.1053(a)(18) Fixed ladders shall be provided with cages, wells, ladder safety devices, or self-retracting lifelines where the length of climb is less than 24 feet (7.3 m) but the top of the ladder is at a distance greater than 24 feet (7.3 m) above lower levels.
    • 1926.1053(a)(19) Where the total length of a climb equals or exceeds 24 feet (7.3 m), fixed ladders shall be equipped with one of the following:
    • 1926.1053(a)(19)(i) Ladder safety devices; or
    • 1926.1053(a)(19)(ii) Self-retracting lifelines, and rest platforms at intervals not to exceed 150 feet (45.7 m); or
    • 1926.1053(a)(19)(iii) A cage or well, and multiple ladder sections, each ladder section not to exceed 50 feet (15.2 m) in length. Ladder sections shall be offset from adjacent sections, and landing platforms shall be provided at maximum intervals of 50 feet (15.2 m).
