Non-plc: Something about scaffoldings

Hi guys,

I'm sorry to interrupt for posting a non-plc related thread, but I think most of you guys should be able to help/enlight.

I'm in the mist of sourcing for scaffolds mobile tower with platform height of 6m. Some quoted me 7 rungs frame, some with 4 rungs frame. Frame height is 2m. Does anyone know if 7 rungs or 4 rungs frame is better?

The price are the same.

Thanks.

OK so
Frame height is 2 M about 7 feet.
One frame has 4 rungs
other has 7 rungs.

Here in USA the common practice and I believe required by OSHA for many if not all ladders is a rung spacing of one foot. Measured from top of rung to top of rung.

Pragmatically speaking get the 7 rung unit - lots easier to climb.
