Chain Driven Excavator Wheel

Our cutting wheel excavation system is for the most difficult deposits.   Current and the chain ladders from the past have solved the problem of nesting in rock and the ability to move large rock from the suction area. Also the chain ladder can move clay from fowling the suction profile. Chain ladders are necessary in certain deposits but also lead to lower production potential due to it’s limited excavation.   So far the only attempt to solve the lower production potential of the chain ladder was the bucket wheel excavator. Although the bucket wheel has enhanced excavation, fowling with rock and clay are still a problem. The bucket wheel application is similar to a rotary cutter, the wheel just rotates vertically not horizontally. Our system is totally unique and achieves all the advantages of a chain ladder, but also solves the limited production of the chain ladder. Our system has a very high excavation action to achieve maximum production and efficiency. This = PROFIT. We have had two producers install a chain ladder systems in the wrong application. Both felt they would increase production with a chain ladder. Both producers eventually went back to the rotary cutter to achieve higher production. For this reason we reimagined the chain ladder design. We addressed the weakness of current chain ladders.  Now with our new chain driven excavator all of the advantages of the chain ladder are achieved and the deficiencies of the past chain ladder systems are eliminated.

There are several advantages with our system:

1. Ladder hang up is eliminated

2. A moving continual screen provides much less chance for plugging with rock or clay.

3. The biggest drawback of current chain systems is the limited excavation due to a small excavation profile. “No cutter wheel” Usually only a few feet of chain sliding in front of the suction mouth. This is just a moving screen with little or no excavation potential. Our system aggressively agitates and excavates material. The excavation wheel has easily 500% more feed potential over a few feet of chain sliding in front of the suction mouth.. This is where it all starts and being able to bring excessive material to the pump is the first key to maximum production and profit.

4. The system is 120 horsepower with 35-foot ladder section. Size 14–18″ suction.       PATENT PENDING
