Hi again guys,
One more sort of OT question. This question deals with hydraulics, specifically porto-powers.
What I want to do is separate two light pole sections. The light poles are galvanized steel approximately 70’ tall (in two sections) and about 20” in diameter at the joint. The poles are tapered and the joint between the two sections is a slip fit joint 1.5’-2.5’ long. Typically the poles are assembled by lubricating the pole sections with dishwashing liquid, then sliding the two sections together and pulling them together with two 3 ton cable hoists. The top section including the light fixtures, crossarms and top pole section can weigh up to 4 tons. This pole would have been sitting out in the weather for up to 10 years or so.
I want to separate the pole at the slip joint without damaging the top section of the pole. I am thinking of using two porta power rams with a single mule (hydraulic pump) to separate these sections.
My question is how large a porta power do I need (or how much pressure will it take to separate the sections)? Will a single mule power both rams to full capacity? Is there a better way to do this?
