Reaction to the ABTT Code of Practice for Tallescopes published in Sig, Dissertation Poll Options

[Ynot]

Hmmm... ™

Based simply on what you quoted .....
(my bold)

A circus worker was in an extended tallescope (a tallescope is a manually operated telescopic aluminum work platform) repositioning a wire rope cable on an arena rafter about 22 feet above grade. The tallescope suddenly retracted downward, then fell over onto the arena's concrete floor.

Ok, we don't know if the Tallescope was being moved or whether the outriggers were correctly deployed etc.

This suggests to me that the upper half of the ladder section dropped vertically, which in turn indicates that maybe the safety catches hadn't taken properly when the scope was extended...
Which sounds very much like a very different type of incident, and one that doesn't really fall into the type of which we're discussing.
I'll watch eagerly for the outcome of Bryson's investigations...

A concurrent post has been automatically merged from this point on.

Will investigate. Link?
