Which Linear Actuator is Best for a Sliding Gate at a Cottage?

[Kapitonov]

I want to put myself a linear actuator on the sliding gate to the cottage. I looked in the internet, there are a lot of offers and the prices are very different. Maybe there are people here who understand this and can advise me what type of actuator is better, manufacturer and where to buy? I will be very grateful.

Welcome to PF.Are you opening and closing the gate?

How heavy is it?

You could probably use a rotary actuator ratchet than linear.

How far does the gate need to move? I think chain and sprocket systems are used commonly for that...

Hi! Thank you all! Gate weight 150 kg. Gate width 3.4 m.
I choose between https://www.haroldbeck.com/actuators/42/model-42-109/ and https://www.actuatorzone.com/electric-linear-actuator

I still stuck with this problem. Can't decide which is better. Any help?

Those linear actuators have stroke lengths a lot less than 3m. How are you going to lengthen the effective stroke to open that 3m gate?

I thought to attach it not close to the far side of the gate.
Or use something like telescopic tube,

Here's what the local airport uses for a gate about the size you mentioned:

The manufacturer is Tymetal: https://www.tymetal.com/. This particular gate is controlled by detector loops in the road, plus the airport manager has a remote for it. There are pushbuttons inside the panel. This is a heavy duty gate designed for many years of use in a climate with summer temperatures over 90 deg F, and winter temperatures less than -30 deg F. So it will not be cheap.
