The winder is a 4-rope Koepe winding machine with integrated motor. This type of design of the winder guarantee long-term stability of the entire drive system. Assembly of the winder in the workshop. 4-Rope Koepe winder. 3+1 Channel brake system. ▫ Statement of the investment and operating costs. ▫ Comparison of . The objective of this study is to monitor four Koepe winder head ropes, which have six triangular-shaped strands and are 38 mm in diameter, by.

It was therefore necessary to arrest the upper and lower conveyances and the moving rope system. The permanent ladder way in the shaft provides access to the headrope cappels.
Both skip pans are removed from their respective bridles at bank level. That is why this kind of hoisting is called “Endlosseilfoerderung” in German, the nearly correct translation of this expression is “endless rope hoisting”. This service may provide the following benefits: Method for changing a head rope. Switch To Mobile Version. In wimder operation, the winder is started by pushbutton and is stopped by the magnetic switches of the helical controller. In case of defect or malfunction, this reserve channel is immediately ready to take over the function of the defective channel.
Single-drum hoists can be used in smaller applications, however double-drum hoists easily allow the hoisting of two conveyances in balance i.
The retardation gear operates through the stepped resistances used in the circuits which regulate the speed of the winder, in this case, the excitation circuit of the Ward Leonard generator. The new tail rope, wound onto the rope service winder and with a cappels attached, is passed over the sheave wheel and is lowered to the shaft bottom. Following acceptance of the study, the decision was taken within a few weeks to implement it.
The solid-tyred roller units, attached at either end of the bridle assembly, reduce wear on the shaft guides and bridle slippers and reduce shock to the bridle assembly. The loading flask is also designed as a removable container and is lined with special steel plates, too. Conveyances operated by the Koepe system cannot be detached from the winding ropes in the event of overwind.
It is fixed under the pit cages and connects their floors. The clamps on the tail rope are removed and the supporting steelwork taken from the compartment. The Ardic controller supervises the retardation of the winder only and shadows the helical controller by a cam and follower system. The head ropes and the bridle are lifted about 30 cm, to provide slack to enable the head ropes. The new bridle is moved into the compartment, the head ropes are attached and then the tail rope connections are put on.
The installation of a Joepe winding plant in a working korpe Part II. Its peripheral length kospe approximately 65 feet. A tachogenerator at each end of the drum shaft is driven mechanically from the same shaft that drives the helical controller or the Ardic controller.
The braking force applied is therefore inversely proportional to the oil pressure beneath the piston. Two 2,5 cm diameter slings are passed through the bridle crosshead and secured to the steelwork at the station.
Statement of the investment and operating costs. The opposite conveyance is hoisted to release the tension in the rope to be changed. The Koepe wheel weighs 70 tonnes, the drum shaft 30 tonnes, and each armature of the two driving motors weighs 25 tonnes.
The foundation for the Koepe winder was superimposed on the existing headgear and the Koepe winder was erected. Control can be diverted from one point to the other by means of a changeover switch. In underground mining a hoist or winder  is used to raise and lower conveyances within the mine shaft.
Kooepe simulation of these deterioration is complicated.
Hoist (mining) – Wikipedia
The retardation controller can be used for other signalling, interlocking or control purposes relative to the position of the conveyance in the shaft, such as:. Rollers attached to the bottom door of the pan run over profiled horns attached to the bridle to op the pan.
This shaft had to be prepared to accommodate the Koepe winder, klepe was to be a single-purpose winding plant to hoist ore from the lowest loading point in the shaft. Loepe the rope is driven by the driving wheel and after this it is sent back vertically into the shaft after passing another wheel at the winding tower.
The principal points of the study were as follows:. Principles and testing methods of earth ground resistance. Completion of the shaft-hoisting system from planning to successful commissioning within only two years Completion of the system as scheduled, including planning and execution of shaft sinking, through optimum coordination of technology and project timing Design and execution of the machinery for maximum availability and minimum maintenance through use of highly reliable state-of-the-art technology In South Australia, BHP BILLITON operates the underground copper and uranium mine Olympic Dam.
The skips are of the swing-out type with a large cross section allowing rapid loading and unloading. Determination of the discardign critera for ropes under deep shaft condiitons and magnetic testing device calibration During fatigue testing under drum or Koepe application the damage as broken wires, abrasion may be recorded and mapped by means of magnetic testing.
The layout of the winder is shown in Fig 6. In he became the technical director of various mines owned by the Krupp Mining Company. The initial installation of all ropes was completed in four days.
To each of the four 27 kg rails were arranged as shown in Winde M — M of Fig. The Olympic Dam Shaft 3 is designed as a downcast shaft for a capacity of 9. The winder drum is rotated slightly to allow the clamps to take the weight of the tail ropes.
The design and wjnder of this protection is important as the Koepe winder installation must provide tail rope protection and must not restrict rope movement or looping.
