DasMorineDC 12V 14 Inch Stroke Linear Actuator with Mounting Bracket 300MM 6000N/1320LB Maximum Load for Recliner TV Table Lift Massage Bed Electric Sofa Linear Actuator (14inch 350mm)

Pleasantly surprised that these do in fact operate fairly quietly. Speed is a tradeoff, but I will be using some gear or other mechanism to offset that. Will update my review once my build is complete with a video.

Used this to open my chicken coop door

A simple test placed between two concrete blocks had no trouble at all pushing the two blocks apart, I do not doubt that it can lift the 598kg as claimed. It has a multitude of uses wherever you need to lift, move, slide or fold anything. It is quite slow, taking about a minute to fully extend or retract but it is very powerful as well as being smooth and quiet. There are two built-in limit switches (not adjustable) which stop the arm movement at both maximum and minimum extent. The two-core cable is marked brown and blue but this does not represent polarity, simply reversing the connection to your power source changes the direction of movement. So a simple control device could just be a basic crossover switch or you could use a more intelligent electronic controller perhaps with a remote control. I have utilised this on our super-king ottoman bed, my wife struggled to lift the heavy ottoman lid (especially with the mattress etc on top). But with a quick modification using this actuator, a push-button crossover switch and a suitable 12v 5a power supply and now it’s just a push of the button and it takes about a minute to silently open or close with no effort on her part at all.

The actuator itself is brilliant, however the brackets that are supplied are useless, they are like butter no strength in them at all. I’d still buy again and plan to do so, but would mount using homemade brackets instead

The media could not be loaded.  Anyone looking at this is probably the kind of person who watches YouTube videos of makers creating cools stuff or doing something epic in their workshop. I certainly am. I also have the advantage of being an engineer as well as having a workshop and thus my next project which is to build a new large workshop fully kitted out is also going to have some lifts for small bench machinery.And along came this to review so happy days because I was looking at hydraulics but now I'll probably use electric actuators to save on mess and make control easier.So, for not much money you get a 12" or 300mm stroke actuator that can lift around 600kg which, is more than enough for anything I'd use this on. To be honest it might lift that but 600kg is a fair amount and I'd probably go for something beefier and double up for safety. However, I reckon this would do that number.This is a 12V DC actuator thus you need a 12V DC supply which is most likely to be a battery. In fact this is probably the cheapest way to do it if you are on a budget. Get a cheap battery and charger which will give you plenty of amps - although this only pulls around 5A max. You can of course get a suitable power supply but that's likely to be more expensive and complicated.Cables come marked blue and brown same as UK 220v wiring for negative and positive. This is misleading because it's DC and it's driven both ways so you need to swap polarities. I used a battery for test purposes and simply changed the cables over but when made up properly I'll use a three position hold over switch that move one way for up and one way for down and on release springs back to the middle off position.The time to raise or lower minus a load is 1min 12sec so slow enough to not get caught out in the way of it. That doesn't mean you can be blasé because 600N of force is enough to easily hurt or worse.Comes with mounting brackets so easily fitted into your project.It's well enough made for 'maker' use although it's not a heavy duty industrial job.For the money, this is a great bit of kit.

The linear actuator was packed well on arrival. The quality is excellent. The poles are very thick and sturdy. The wires are easy to connect ( I did get someone to do it for me). Also the brackets were supplied so it made mounting it very easy. Good value for money.

The media could not be loaded.  I have been looking for a while for a linear actuator for a DIY product. This should be able to fit the bill.The actuator moves around 30cm, and has internal limit switches. These are not adjustable so whatever you are implementing it in will need to ensure that power is cut before it got too far. Apparently it is able to produce a push of 6000N (which would be the equivalent of lifting more than 600KG) and pull at 4000N, so it could well damage anything that gets in its way.The actuator is impressively quiet too. In the attached video you should be able to still hear the clock ticking in the background.It is 12v, but only rated for indoor use. For this test I just had it going from a wall adapter.It comes with a bracket for each end allowing it to rotate slightly from its connection points. These are held in by a thick bolt and pin.The cable length is reasonable, but I could foresee that some will need to extend it.All in all a decent product I think

The build quality is good. It has plastic casing around the motor gears and a plastic cap on the extending end of the actuator but the main shaft and casing is made of metal so it feels nice and sturdy. The base of the linear actuator has a metal mounting point and it also comes with two metal mounting brackets.It takes a minute or two to fully extend so it isn't fast but it is very powerful. it's designed for things like electric wheelchairs and electric sofas so it makes sense that it isn't fast.I have a couple of projects in mind that I want to use it for, either a system to raise and lower my screen behind my desk or a powered car creeper that raises up into a stool. I have tested it and it has plenty of power for either project. I just can't decide which one I want to make first.Overall it works great and I am very happy with it.
