Overall view of gate. This gate has two integrated Swing-Out gates so cows can come to the holding pen from the left or right. Both Gates pivot in the center. Where and how they swing is up to you.

Crowd Gates
....are a lower-cost alternative to air-driven Gates, mostly because they do not require an air compressor and the air drier to go with it. Also the controls are somewhat simpler.

A 2 hp 3-phase motor coupled to a 60:1 gear box make up the drive. You can vary the speed and the force of the gate by exchanging
1) The gear box to a lower ratio, e.g 30:1, 40:1, or 50:1, and
2)  By exchanging the two pulleys to different diameters

Electrically driven gates come in two versions - those you can lift anywhere in the holding pen and those you can't. Gates without lift are standard, but lift cylinders are optionally available. The cost of electrically driven gates with lift are roughly the same as all-air gates. 
The design of the basic carriage is identical for all gates, by the way.
