What is wrong with this picture?

LOL, er, no. I'd sure like to watch the first few crews try to open those gates in the dark early in the morning at start of shift in the demo of the old building. Trying to push them in the way you describe, then uttering some expletives, then pushing one sideways up the slope and watching it roll back down the slope on its own... "Hey you two, come here and hold these ***** gates open!"

Nononono, you misunderstand the goal. Just look at the latest updates from the IT job market. The idea is to discourage people _leaving_.

They managed to do a poured concrete floor such that a welded steel frame door, after installation, had a half inch gap on one side.

Makes one wonder - if apparently not the universal language of math - what language the architectural blue prints were rendered in...

A quick technical update -- I saw the gate today and it is held open by the roller bearing friction on the rails. I didn't see any hold-open latches or anything. They've been using the gate for demolition equipment and support trucks, and it seems to stay open just fine. I'm resisting the urge to do the WD-40 experiment on the roller bearings...

If you have time to service the rollers with WD-40 for them, you might also consider changing a car's radiator coolant, then cleaning all the insulators on their electric fence by dressing them with a light coating of dilute glycol from a spray-bottle.

A more constructive observation is that a spot of glycol (hygroscopic), on the clear plastic face of a moving coil meter, attracts sufficient moisture to bleed off the external electrostatic charges that can cause weird errors of the pointer readings. To test meter sensitivity, just wipe the external meter face with a dry finger. If the pointer moves or dances wildly, dab the outside surface with a spot of dilute glycol.

First thing was - it doesn't close all the way. Then I was guessing swing gate. But closer look at the photo - it looks like there are some rails, but they don't appear to be level, so not sure how that's going to go.
