DBI-SALA SRL Fall Arrest Blocks

All models of the DBI-Sala Sealed Blok and the Ultra-lok are available from Lifting Safety at hugely discounted prices, with many being readily available to buy online.

For both the SALA Sealed-blok and the SALA Ultra-lok SRL (Self-retracting Lifeline), there are a variety of cable length options, with the choice of galvanised or stainless steel wire rope on most lengths. All of the sealed-blok's are certified to EN360, but some are also certified to EN1496, whereas the rescue option is not available on the Ultra-lok series. The sealed-blok is available in working lengths from 4.5 metres up to a huge 53 metres, whereas the Ultra-lok is only available with a maximum 25 metre working length with the shortest length being 6 metres.

Both models are available with the 3M DBI-Sala RSQ function (but not all working lengths have this option), which is a toggleable setting on the fall arrest block, where when the RSQ function is selected/engaged, the fall arrest block will not only arrest a fall, but it will also then slowly descend the arrested party at a controlled speed, which can be used a rescue or self-rescue means.

Automatic descent is not always a good idea, or the best idea, or even an option, though. For example, the last thing that you would want to do if a fall was arrested above machinery is to descend into the machinery automatically. Another example is working down a manhole with a rescue tripod like the Sala UCT aluminium tripod as your anchorage point supporting the fall arrestor. After the fall has been arrested in this situation, the likelihood is that you would want to rescue by raising the casualty, so you will need either a separate means of rescue, i.e. a standalone EN1496 rescue winch, or the variant of the Sealed-blok with the rescue winch (EN360 and EN1496) built into the device itself.
