The bridle of the conveyance on the side nearest to the rope service winder is driven to the lowest main station of the shaft and supported from the steelwork at the station. To a large extent, the headgear is designed as a box-type structure with a minimum of smoothly painted surfaces which make it especially resistant to corrosion.

Koepe winder

View of the helical retardation controller. Discharge flask The discharge flask is also lined with special steel plates. In he became the technical director of various mines owned by the Krupp Mining Company. Principles and testing methods of earth ground resistance. The auxiliary winch lifts the capped end of the rope to the underside of the conveyance. From Wikipedia, the free encyclopedia.

Windre head rope to be removed is now clamped and suspended from support steelwork D at bank level in the compartment nearest the service winder C. The design and construction of this protection is important as the Koepe winder installation must provide tail rope protection and must not restrict rope movement or looping.

So there are two pit cages fixed at each rope – one moving upwards and the other moving downwards the shaft at the same time. Joepe tread trueing device is incorporated in the design for this purpose and may be used during winding operations.

Definition of Koepe winder – glossary

This Koepe winder has operated satisfactorily since its commissioning in Marchfor the hoisting of mineral and has augmented the capacity of the shaft considerably.


New friction hoists are less expensive than new drum hoists, and the lead widner for delivery may be shorter as there is more competition for manufacturing.

This page was last edited on 21 Aprilat A 3 m diameter sheave wheel mounted on the bank on suitable steelwork was koe;e and this could be placed wlnder various positions as required. Braking system The braking system of the winder is designed as a multi-channel brake with a fully closed-loop controlled safety brake.

Two 2,5 cm diameter slings are passed through the bridle crosshead and secured to the steelwork at the station. Some tons of ore per month could be brought to surface if optimum performance is attained.

In underground mining a hoist or winder [1] is used to raise and lower conveyances within the mine shaft. Comparison of the technical data, design, kepe availability of the planned machinery with reference plants.

To simplify work on the rope including pulling the ropes through the rope thimblea clamping and lifting device CLD is provided that is designed to clamp all four hoisting ropes under full load.

These generators feed a DC circuit in which is a relay that trips on low current. Testing under Drum Winder conditions. The winder completes the cycle at creep winer Point D where it is stopped by the application of the mechanical brake.

Saunders and Koeppe Shore bottom discharge skips were installed see Fig. In automatic operation, the winder is started by pushbutton and is stopped by the magnetic switches of the helical controller.

A rope is now wound on the rope service winder passed over windee sheave wheel at the bank and is clamped to the old tail rope, which is pulled up a short distance to enable the connecting pin to be removed from the attachment under the conveyance in the headgear.

That is why this kind of hoisting is called “Endlosseilfoerderung” in German, the nearly windr translation of this expression is “endless rope hoisting”. Retrieved from ” https: The skip pan returns to the vertical position and the bottom door closes and locks simultaneously. The opposite conveyance is brought to the bank level.


Because drum hoists do not have tail ropes, the hoisting system is more suited to slinging beneath a conveyance. Device for lifting and supporting the drum shaft.

Hoist (mining)

A weight of kg was dropped from various heights onto a friction block secured to a rail. The ore pass control chute is fitted with a pneumatic radial cut-off door. To guide the skips in the shaft on ropes to minimise the time-consuming installation work koele the shaft. The guide frame is hooked into a tripod block frame to keep foundation work at the shaft collar to a minimum. Arrangement for attaching the chain block to the cappel. This unusual koe;e considerably increases the period before the highly time-consuming operation of pulling the ropes through the rope thimble becomes necessary.

The maximum daily hoisting schedule wimder the Koepe winder is approximately 22 hours. EE PublishersArticles: The skips are discharged by swinging out the tubs by use of slewing beams operated by hydraulic cylinders. Its peripheral length is approximately 65 feet.

Deep Mining, Rope Service Life and Performance Evaluation

The winder is designed to haul a payload of 20 tonsnes from a depth of m at a speed of m per minute. The use koep an integrated 3-phase asynchronous motor is ainder absolute novelty. Underground mining Vertical transport devices Winches. The head rope to be changed is disconnected from the bridle and the cappels is removed. It is manufactured in two halves and is of all welded construction and has a total weight of 70 tonnes. The machine’s driving wheel.

Lubrication of the main bearings is by a gravity feed from an overhead tank which can be filled by pumps. A simple and effective method was devised to do this:. Design The Olympic Dam Shaft 3 is designed as a downcast shaft for a capacity of 9. They are secured to the steelwork by phosphor bronze bolts whose heads are countersunk into the wlnder.
