Bulkmatic Rod Gates are used as emergency shutoff gates for bunkers containing lumpy, abrasive material.
The pins are manufactured from 304 stainless steel. Two holes on the pin insertion side result in a sturdy cantilever support for the pins. A locking pin ensures that the rods cannot be pulled free of the guide holes. This ensures that the rods cannot be lost while the gate is in the fully open position.
The rods are usually knocked into the head of material using a mallet. For large gates a hydraulic cylinder can be used to push the pins into place. A smaller single cylinder is often used for this purpose and a specially designed tray holds the cylinder. The cylinder is moved by hand from one pin to the next.
Standard material of manufacture is a mild steel frame with stainless steel rods. Other materials of manufacture are available on request. Optional extras include ceramic liners to the sides of the gate.
Standard sizes include: 150, 200, 250, 300, 350, 400 and 500.
