Chain Bucket Elevator
A chain-bucket system was manufactured to lift material from shafts. The elevation depends upon shaft depth. This system is made with 36 m and 42 m and was used at Toheed Tunnel Project for the first time. The electro-motor, gearbox and chain-wheels transmit the power.
Hardox 450 type plates are used in buckets to protect them against erosion. Rate of material transport with this system is 36 cu m per hour.
