Hydraulics or gears, which of them is better in terms of durability and maintenance installing automatic gate?

Question

I have a steel gate at home and i am thinking of installing automatic gate (opens with remote control). I have received quotation from different companies and some of them are using hydraulics to open and close and some using gears.

each of them claims to be better than the other.

Since this is my first time and had no experience or knowledge about it.

I would like to know which is better in terms of durability, maintenance (cheaper to maintain)

Help please

thanks

Answer 1

Hydraulics is the better choice as there are far less moving parts to deteriorate. You will have smoother quieter operation. In the long run it will be cheaper to maintain.  

Answer 2

i would go with hydraulics, it might open slower but will last longer
