Kundeanmeldelser for VEVOR 30 tonn 4 tommers slag hul hydraulisk sylinderjekk 66000LBS løftesylinder Industriell slitesterk bilkarosseribøying

Démontage douilles sur mini pelle. A parfaitement répondu aux attentes.

Only one star on "easy to use" because it is said to be 66 mm inside. Perfect for me as I was about to pull out a 50 mm axle on an excavator. But it isn´t 66 mm inside. It is only 35 mm in the ends and 33,5-34 mm between the ends, meaning that I had to use longer pulling bars and some 50+ mm inside diameter thick wall tubing (pictured) to get the job done. This is costly but Vevor refunded me 30% to compensate for this. But what worries me is that Vevor hasn´t updated the product specifications even after two weeks. How many more products have the wrong specifications just because Vevor doesn´t know how to make a simple measurement? And even worse, how many more products still have the wrong specifications after their customers has filed a complaint? Only four stars on quality because the hydraulic port doesn´t have a ground flat for a Tredo sealing washer. Yes, you can use liquid thread sealant which I did, but a ground flat and a sealing washer is the preferred method. And PTFE tape is absolutely forbidden in hydraulics. The reason for this comment is that the cylinder is supplied with a Chinese hydraulic connection that isn´t used in Europe so you have to change the connection. The thread is female R3/8" if anyone plans on making the same modification. But once the above has been solved it does the job and that´s the reason for five stars on "Functions". I strongly recommend buying a hydraulic pump as well because using a 30 ton cylinder with a manual pump isn´t exactly a joy. I had to work really hard for each pump stroke to achieve a one mm move of the axle I was pulling and the axle was 320 mm long. You do the math! 😊 It ended with me buying a hydraulic pump from Vevor as I have another three axles to remove.

Good

It's very good but I was expecting a female end on the ram to join the male end on my pump

I used this a couple of times. I bought it to to pins and bushings on heavy equipment but have yet to do that yet. I used it to hold a piece of plate steel in place to do some reinforcement. Ended up dropping it right on the hose connection and ripped it out threads and all. I had some NPT taps already and retapped the hole and got it back together and fixed.

Beste , ben zeer tevreden over deze aankoop. Toch wacht ik nog steeds op een antwoord op mijn eerder gestelde vraag. Graag had ik enkele koppelingen bijbesteld, identiek als degene die bij de hydraulische cilinder geleverd werden. Alvast bedankt
