We are set up with 3 tandem bays. The inside portion of the tandem bays have four 10'x10' overhead
doors & for our RV-truck bay there are two 13'x11'
doors with the one in front no roof but 8'x20' windbreak fiberglass-redwood homespun structures. Via cameras we can do some closing & opening remotely via ZAP operators that Airlift sold back in the day as their extra safe (Made in England)
door opener option. We don't auto operate the Zap operators or let the customers use them even though I believe they are safer than standard
door openers. There has never been an incident of a customer not being able to safely use the ropes on the
doors. The signs clearly state that the
door must be lifted completely open to prevent an unwanted fall down.
In our North Dakota climate there are times during the winter when we have to make sure ice does not build up on the overhead
doors. Airlift's strapeze counterweight system have been a life saver for us compared to if we had been stupid enough to put in torsion springs.
Our main & very almost brand new self service competition "sensor auto opens & closes" the
doors for their customers 24/7 ... time will tell if they will be able to maintain that luxury in my opinion. I am sure we have lost a few customers because of that luxury convenience. Does anybody else uses that approach? My mindset is that if the customer opens & closes manually & the
doors are kept light enough for even dainty women ... it makes more sense it seems to have the customer be in total control & not have to rely on sensors.
Having the rope on at least one
door does stop the tunnel wind effect ... that is why even above freezing temps we allow our customers to close our south
doors even if the wind is coming from the north.
BTW ... we had a custom setup made about 19 years ago that a machine shop friend helped us with to
lock our
doors from inside the equipment room by use of air cylinders & linkages etc. Definitely something worthwhile knowing what it was like to fight with the locking mechanisms on our previous overhead non alaskan
doors.
Debra ... depending on to what length some northern cold windy area operators want to share ... this thread could turn out to be veeewy intteeerestingg. There was a Canadian Style 14 bay indoor self service back about 1984 here in Bismarck that was closed down because they were not keeping up with the payments on their SBA loan ... that was really something with a US Marshall involved in the shutdown etc. By Canadian Style ... just two
doors with many internal bays a bit like a parking ramp. There was at least one Canadian operator with that type of format on this car wash forum. I believe he was from Winnipeg, Manitoba.
