Industrial Mine Shaft Weights | MarsMetal Specialty

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 shaft elevators are critical for moving men and equipment through the various mine levels stretching hundreds, and often thousands of feet deep. The car itself requires a

DESIGN OF MINE SHAFT ELEVATOR

counterweight is attributed to the end of the suspension rope and the other end is connected to the car. 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

How to Calculate the Size of a Mine Hoisting System

Then, in whatever position the cages are in the shaft, there is the same weight of rope hanging in each compartment. Thus the entire weight of the hoisting mechanism is in perfect balance at all times, and the engine only has to raise the weight of the ore and overcome the friction of the moving parts. The main rope may be wound on a pair of cylindrical drums, or it can be wrapped back and

Hoist (mining) Wikipedia

In underground mining a hoist or winder is used to raise and lower conveyances within the mine shaft.Modern hoists are normally powered using electric motors, historically with direct current drives utilizing Ward Leonard control machines and later solid-state converters (), however modern large hoists use alternating current drives that are variable frequency controlled.

The counterweight weighs about the same as the car filled to 40-percent capacity. In other words, when the car is 40 percent full (an average amount), the counterweight and the car are perfectly balanced. The purpose of this balance is to conserve energy. With equal loads on each side of the sheave, it only takes a little bit of force to tip the balance one way or the other. Basically, the

Mine Hoist | Article about Mine Hoist by The Free Dictionary

The receptacles used in mine hoists may be cages, skips, or buckets. Depending on whether or how the weight of the hoist cables is balanced, the hoisting may be unbalanced, statically balanced, or dynamically balanced. The winding drum or driving sheave may have a single radius or a large and a small radius. Cylindrical drums and Koepe sheaves have a single radius; bicylindroconical drums have

Counterweight Wikipedia

A counterweight is a weight that, by exerting an opposite force, provides balance and stability of a mechanical system. Its purpose is to make lifting the load more efficient, which saves energy and is less taxing on the lifting machine.. Counterweights are often used in traction lifts (elevators), cranes and funfair rides. In these applications, the expected load multiplied by the distance

Mini-pat: a mine needs a lifting system Grade 7-9

The mine cage and skips are raised when the steel cable winds up again. Part 2: The sheave wheel is a pulley wheel that sits above the mine shaft. The hoist cable passes over the sheave wheel and then down the shaft of the mine. The sheave wheel reduces the sliding friction of the mine cable. Part 3: The head frame is the structure that supports the sheave wheel. It must be strong enough to

How do elevators and lifts work? Explain that Stuff

11/06/2019· The counterweight makes it easier for the motor to raise and lower the car—just as sitting on a see-saw makes it much easier to lift someone's weight compared to lifting them in your arms. Thanks to the counterweight, the motor needs to use much less force to move the car either up or down. Assuming the car and its contents weigh more than the counterweight, all the motor has to lift is the

Underground Mining Transportation Systems

A cage used for lowering and raising persons must be covered and equipped with gates for safety. The size and number of decks on the cage depends on the size of the operation and the equipment being handled. Cages vary from a single deck up to a triple deck.
