The PEBCO® Rod Gate is commonly used as a maintenance gate that is placed above crushers or other equipment.

Traditionally this style of gate has rods that are 1 ½” - 2” in diameter entering the gate frame from one or two opposing sides. The rods are driven in with a sledgehammer and extracted with a come-along, chain-fall, or other manually operated hoist. In many applications this works quite well, especially with gates that are 30 inches square or less and because these rods are reasonably easy to insert and extract the occasional nature of their operation results in a cost effective solution for the plant.

Unique to PEBCO® Rod Gates is they can now be provided with a Hydraulic Actuator.

How Does PEBCO Operate a Rod Gate Hydraulically

N/A

PEBCO® has designed a Rod Gate that utilizes a hydraulic cylinder on each of the opposing sides to insert and extract the rods individually. Each cylinder is mounted on a trolley assembly that can traverse the entire width of the gate. The manually operated directional control valve is also mounted on the trolley for motion control of the hydraulic cylinder.

The cylinder is positioned directly behind the rod that is to be inserted or removed and the ram extended until it engages the back of the rod. A groove is cut into the back of each rod that engages a custom designed receiver mounted to the end of the cylinder rod and a clip is inserted over the receiver to lock it onto the rod.

The cylinder is then actuated in the desired direction to insert or remove the rod. The clip can then be removed, the cylinder retracted and the trolley moved to the next rod where the process is repeated.

Why Choose a Hydraulic Rod Gate Vs a Conventional Slide Gate

N/A

Hydraulically operated Rod Gates still prove to be a cost effective solution when compared with hydraulic slide gates of equal size. Conventional Slide Gates or Knife Gates can require tremendous force to close through a static column of material as the operational forces increase exponentially with the area of the opening.

A Rod Gate can minimize actuator force requirements by closing off only small sections of the opening at a time with the pointed rods that tend to push material out of the way. The problem most often encountered with large Rod Gates is that the operational force to insert a single rod is still more than a man can generate with a sledgehammer. In this case, hydraulics can be utilized but on a much smaller scale than a conventional Slide Gate.
