TRAM - Advantages
- Robust components that requires little maintenance
- Designed by experts in the fields of ergonomics and engineering and is certified and tested to international standards
- Fall restraint rather than arrest
- A Travelling Hand Rail provides a stable environment in which to work.
- Fall Arrest Rated for instances where restraint is not possible
TRAM vs Traditional Fall Protection
- All fall arrest systems allow workers to drop while the fall is arrested. There is a very high risk of trauma through impact with hazards below.
- Fall arrest systems are subjected to much greater loads as vertical fall is arrested. The total load on the static line system is much greater than the loads on a travel restraint system.
- When a worker falls on a static line system the cable trolley will slip along the cable to the midpoint of the cable span. This effect increases the risk of impact as the person falling may be travelling horizontally, as well as dropping vertically, during the fall.
- After a fall, all static line systems must be taken out of service until they are inspected and re-certified. Costly repairs are not covered by manufacturer's warranty.
- Pop-up guard-rails are typically 35.4" (900mm) and lower than the centre of gravity of most workers. They are therefore unlikely to prevent a worker falling over them if they lose their balance or are struck by a foreign object.
- Guardrails do not prevent a fall on the same level.
- Floor/deck-mounted horizontal lifeline systems (HLL) can snag and accelerate a fall on the same level.
- Overhead HLL systems can snag and suffer from trolley hang-ups.
- Falls with HLL can cause suspension trauma.
