PCS Scissors Creek – Rope-Up & Cage/Counterweight Installation The scope of this project was to rope-up the new Koepe hoist at the Scissors Creek mine site. As this shaft was a bare shaft, the scope of work included the installation of all new guide ropes, balance ropes and head ropes along with the installation of a new cage and counterweight.
Osborne Mine is a copper/gold mine and processing operation located approximately 195 kilometres south-east of Mount Isa in northwest Queensland. Mined ore is processed through an underground - primary crusher and then hoisted to the surface via a 700 metre shaft and a double drum winder with a skip/cage combination and counterweight.

Mine hoisting systems are comprised of five major components: hoists, conveyances, wire ropes, shafts, and headframes. Each of these components requires extensive design considerations. ... This type of drum hoist is good for …
cage/counterweight configurations are well suited for multilevel mines. The counterweight solution is also preferable when hoisting dis-tances are short. Friction hoists are normally the most economical solution for permanent …
These sheaves are fitted with friction linings, including rope grooves, on the outer rim. With a usual contact arc of 180 to 200 degrees, the shared ropes for both shaft hoist ways are running in the rope grooves. Frictional engagement between the rope grooves and the ropes transmits the movement of the traction sheave to the ropes and limits ...
Get a Quote Mine shafts pose special and complicated elevator counterweight issues. Not only does the elevator car need counterweights but it usually requires guide wires to keep the elevator properly aligned within the mine shaft. Mine …
This allowed the counterweight to fall to the bottom of the shaft, causing the car to overspeed and crash into the overhead structure. Accident: Coal Mine Friction Hoist December 1977, the personnel hoist cage at Island Creek Coal VP-5 Mine crashed into the headframe at 4734 ft/min. or 53.8 miles/hour.

A cage or skip in which people are travelling should not be accelerated or decelerated at a rate greater than 1.5 metres/second/second. In cases of an emergency, deceleration of the cage or skip should not be less than 2 metres/second/second or more than 5 metres/second/second. 6.3.8 BRAKE. The brake on a winder should comply with the

During a car (cage in mine) rising, a counterweight accelerates it. Contrarily, when the car descends, the counterweight slows it up, and in the result the less power consuming of the engine occurs. Guide rails are indispensable components of elevator systems as well. Not just they balance a car, they help the car to move properly as well.
The counterweight balances the load in the lift-shaft. ... The winding house houses the engine that raises and lowers the mine's cage (lift). What happens in the winding house of …
