12V 8"

Have it on my snowblower shut. Delivered on time and works as needed.

I used this little miracle device for my new yard sweeper. No More hopping on and off the lawn tractor to change the sweeper height. I wired this to the 12 volt system and installed a up down switch. Game changer!

The ECO-WORTHY Heavy Duty 330lbs/1500N Solar Tracker Linear Actuator does exactly what I need. I use the 300mm version to keep my solar panels optimally pointed at the sun. I also use the ECO-WORTHY Linear Actuator Motor Controller. Together the ECO-WORTHY devices work flawlessly. The Actuator is quiet. The controller switch is modified (yes, breaks warrantee. It's okay) to allow for a Wifi switch to trigger the motor controller. Tech info: Use the Wi-Fi device "inching" capability to trigger up/down configured to time after/before sunset and sunrise. Using Wi-Fi also allows me to manage the Actuator while away from home.

I bought two and fabricated a system for them to open and close the levers that work the pins that hold on my tractor bucket and attachments. They worked great. No more getting on and off the machine to release/attach my bucket, grapple, etc. They were perfect for the job. I used them for about six months, worked perfectly. It was a stupid thing that i did the caused one of them to explode. They have a built in stop switch when reaching full extension or retraction. I thought they would stop if they reached maximum load limit, but i found out otherwise. I accidentally caused one of them to be grossly overloaded (stated capacity of 330 lbs, i had it up against an immovable object) and instead of stopping, it continued until it literally blew the gearbox off the back of the unit with a bang. The back of the gearbox flew away, the gears went in opposite directions. The screws that held the cover on stripped out of the housing. It was all my fault, but on the good side, i got to see the innards of the unit and am very impressed with the quality or the parts and the manufacturing. No plastic junk. I'd give it 5 stars, but i can see instances where an overload might occur in many applications. I feel it should not self destruct. Other than that it's well made and designed to last. Good product if you dont abuse it.

It works like a champ. The brand new one that arrived with the Eco-Worthy Dual-Axis Sun Tracker, quit working within a week! Thank goodness for replacements that apparently are NOT UNDER WARRANTY from Eco-Worthy.

I needed a way to easily lift my very heavy hot tub cover. The manual lift I bought just didn't cut it (it was the cheap one). So I engineered a way for these to work and they have performed perfectly. Yes, as you can see in the video... a bit slow and noisy. But for the price and ease of installation.... Can't beat it. I installed a 12v adapter fed from the hot tub's electrical system, and installed a DPDT switch wired to control direction. They have a self liminator, so rarely is there a reason to return the switch to the center position unless I need the lift to stop half way through.

Eco-Worthy has horrible customer service! If you can even get a hold of them, they will take no responsibility for the product, and blame the warehouse and tell you to send an email to China to wait for a reply that takes forever. I'm on my third one of these that obviously the pallet fell from height and damaged multiple units because I have received them broken in the same place. Motor detached, actuator rod end damaged so bad it won't accept mounting pin. Third one is in mailbox waiting for me when I get home so we will see...

Not sure how someone rated this as heavy duty or over 300 lbs. My shaft bent under less than 300 lbs. Before it bent, it worked well. I bent it back into place but it's not perfectly straight.

Je l'aie utilisé pour lever ma gratte de moto-neige.

I already had a few linear actuators, but they were too long for my application. I received this 4" version and was impressed right away by the fact the they actually use an o-ring to seal the assembly from allowing any water/dust etc to enter the body. The unit itself operates perfectly and I'm confident that it will give me years of service.

Awsome lift for our RV bed storage area. Very strong, quiet and useful. Great accessory for our RV.

Pas rapide pour levé et descendre j'ai mis une vitre sur le toit de mon spa pour faire sortir la vapeur d'eau
