Today is 11th, Nov., 2015. I send a set of hydraulic jack with hand oil pump to my Uzbekistan customer. This is a 100 ton single acting hollow jack, stroke is 100mm, center hole is 40mm, body height is 285mm. It is matched a hand oil pump, its oil capacity is 950Ml with a 1.5m oil hose. The single acting hydraulic jack could match a electric oil pump, like the second photo, this is a electric oil pump.
My customer bought the jack, he want the jack to tension a 33mm wire. The single acting hole jack also could be used for lifting heavy on bridge and building.
