Rigid rail fall protection is the most popular line of fall protection equipment and has become the industry standard. Trolley beams are considered the most effective fall protection and deliver the safest fall arrest. FPS is the leader in this style of fall protection sales and installations.
The patented high strength integrated truss-based systems by Fall Protection Systems, has made FPS, the leading system manufacturer and installer in all of the Americas and is covered under US patent numbers 6,269,904B1 and D440,023S.
Secondary falls are a serious concern with cable systems. A safety cable behaves similar to a rubber band under load. A tensioned cable "bounces" a fall victim during a fall arrest, an effect known as a "Secondary Fall". Secondary falls are often more damaging to a fall victim that the initial fall arrest.
To minimize cable deflection and spring-back during fall arrests, safety cable systems cannot span long distances without using several intermediate attachments.
Safety Cables typically allow a falling worker to drop several feet before the fall is totally arrested, creating a much higher likelihood that a fall arrest victim will strike an impact hazard below. For example, slips and trips on a cable system are quite likely to cause a worker to strike his knees on the walking surface he is traversing.
To prevent excessive drag resistance on a walking worker's harness attachment, safety cable trolleys must pass smoothly over the intermediate connections without hanging up on the attachment brackets. Intermediate attachments must support the cable to minimize fall arrest deflection, however, the cable trolley must be able to pass these attachments without losing its hold on the cable.
Regardless of the manufacturer, all professionally engineered safety cable systems, must be quarantined after a fall arrest, and a thorough re-certification-inspection by a competent person is required before the system may be used again.
