Dual Linear Sliding Gate Operators Replaced in South Chicago Facility

ECI was called in last year to replace dual sliding gate operators for the facility as shown in the image above. The entry gate at this Chicago south side location is to the right of the guard building and the exit gate is on the left. Notice the black box housing one gate operator behind the gate, between the dark vehicle and the light pole on the left in the image.

Both the previous sliding gate operators and the replacement units were furnished by Nortek Linear? (OSCO). Shown below is a close-up view of the sliding gate operator on a standard post mount. An optional pad mount is also available.

Linear? offers commercial duty slide gate operators available in one-half, one and two horsepower versions. The 1/2 horsepower model has the capacity to move gates up to 45 feet in length and weighing a maximum of 1100 pounds. The one horsepower unit can handle gates up to 78 feet in length and 2500 pounds. And the two horsepower unit supports gates up to 100 feet long, weighing a maximum of 4000 pounds.

The tan wire to the right, in the picture above, leads to a small rectangular box mounted on the post. This is one end of a photoelectric beam and the other end is across the lane. A similar hookup can be found on the other side of this post. These signal the gate operator when a car has entered or passed through the opening and then trips a relay so the gate can automatically close.
