QWORK 20T Mini Hydraulic Cylinder Jack Porta Power Ram 2" Stroke, CP-180 Manual Hydraulic Hand Pump, Single Acting Lifting Cylinders for Machinery Shipbuilding

I am using this hydraulic ram and pump to re press truss plates on a garage roof. I needed something the would work in the horizontal position and this worked just fine. I do wish there were instructions included showing how to add hydraulic fluid. Tip: The pump will work in the horizontal position as shown and it also in the vertical position if the hose is on the bottom. The ram works in any position and it has a built in return spring making it much easier to work with.

I used it to press a 3/8" thick piece of steel back into place after it got damaged. Used it like a porta power. Worked excellent. It needed to be less than 5" tall to fit between the two pieces that needed to be bent back to a 7" gap.

Works very well

Just opened mine, and it DOES NOT WORK! In trying to figure out if I'm doing something wrong. I started reading other negative reviews, and some complain of no oil. Well, when I attach the pump to the ram on mine, then disconnect it, a few drops of oil do come out, so it at least has some. Both check valves (on the pump and the ram) are closed when the two are disconnected, so it's not that it all leaked out. I am curious about one thing (hopefully the manufacturer is reading the reviews). There are are small pins on the open/close valve knob. There is one on the knob, and one o the body of the pump under the knob. When twisting it to on, the pins bump each other stopping the knob from turning any further. It does not feel ,Ike like the valve is closing all the way. I'm thinking about clipping these pins off. Any advice?

After reading reviews mainly complaining about no fluid, not working, or no instructions. First I wanna say people make it sound difficult and probably not a person who works in a hands on field. Ordered 3 they all worked out of the box! Because of the reviews the first thing I checked was fluid. Simply unscrew the yellow tube from the top and found 1/2 tube full of oil. When you get it out of the box remove the plastic ends and hook up the hose to the ram. It does take up to 15 pumps before it starts to pick the first time and get full of fluid. Next these types of things are made to lift extremely heavy loads. They dont lift quickly. Probably 50 pumps for 2 inches. Which if you truly are picking something in the 30 to 40k pounds its something your gonna want control. For me we was jacking up a 60 foot tall tank so we needed control to make sure it didn't fall over due to the wind.

Nice tool, but didn’t come with any documentation. No warranty, no owner’s manual. NO INSTRUCTIONS This is actually a dangerous situation. I almost bought the wrong fluid. A real novice could have hurt himself trying to guess how the thing works

Good Quality portable pump I used it to lift a roof truss to make a repair and it didf the job.

Excelente

I needed a small port-a-power with a short ram, this worked perfectly for my project with much more reserve power than I required.

Excellent et très fort bien construit

Had to add fluid to get it to go all the way up. After that it worked well

The unit didn't work out of the box. It appears there is no hydraulic fluid. There are also no instructions on how to bleed the air and refill the cylinder with hydraulic oil. I spent over an hour bleeding some air and adding hydraulic fluid at both the pump and jack ends, but it still didn't work. A simple page of instructions would have gone a long way and saved a lot of wasted time.

Worked very well, no complaints, great value
