In general terms a "commercial" motor will be more suited to higher duty cycles. Some operators are designed to work all day long whilst others like a more laid back lifestyle and prefer a home with lazy usage. If however the gate/s performed 25 operations for half an hour in the morning and the other 25 during a half hour period in the afternoon then this would be considered medium to high duty cycle. NUMBER OF DAILY OPERATIONS OR "DUTY CYCLE" - In general terms we consider even 50 operations a day to be a small number assuming that the 50 operations were spread evenly over an eight hour period.So, note down your wind and slope resistance level - "low", "moderate", or "high". A 200kg gate on a site that slopes 150mm from end to end can effectively weigh 1000kg as far as the motor is concerned. Any slope off perfectly level will have a large effect on motor choice (Look for a motor marked " GOOD ON HILLS"). Note that unlike swing gates where wind resistance can be critical with sliding gates the wind resistance although real is not considered critIcal but more a "point to note". EG: Wind resistance of a fully enclosed sliding gate of 5.5 metres width in a coastal environment would be considered "high" whereas a well protected site and an open design gate of the same size may be considered "low". You need to consider your wind resistance taking into account site conditions and size. A gate with 25mm vertical uprights at 150mm centre's as it's main centre infill will have a smaller wind resistance than a gate with a totally enclosed centre infill of say timber or colorbond. GATE CONSTRUCTION AND SLOPE - The main point to consider here is the style of gate.So note down your gate weight as your first point of reference. We assume that you have a good set of wheels and guides or you will be choosing a good set of wheels and top guides. Although width is a consideration the weight of a sliding gate has the major influence on choice of sliding gate motor. Listed below are factors you should consider when making your choice. Next, I surrounded the post with cinder blocks and more concrete between the steel post and the cinder block, then used bricks.There are many factors that together combine to help you choose the right operator for your gate. Then I filled the 6" 圆" post with concrete. Mine stated with a 6" x 6" square metal pole, stuck 6' into the ground, with concrete poured around the large hole I dug for it. I hope you built one hell of a post to mount your gate to, given its size. If not, the gate opener will take the brunt of the force when it comes to a stop. Also make sure you have a very sturdy, positive stop for the gate when its in the open position. I have sensors that I mounted in the driveway to prevent the gate from closing on a car, or more importantly, my 4 or 6 year olds. Also needed by Gas/Electric to read the meters. Same goes for the Gas/Electric company (in case there is a gas leak). In my area, an over ride switch with a universal key is required for the fire department. There are other things you should look into when installing your gate. During big storms, the gate almost doesn't want to open with the wind pushing against it. We live at the very top of a hill (about 2000ft above sea level) and a half mile from the Pacific Ocean in San Diego. In the long run the movement will destroy the gate opener. The wind can really move a gate that size around. Be sure to buy an electric magnet to keep it firmly shut. I ended up purchasing a GTO/PRO SW4000XL.
