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.

Because drum hoists do not have tail ropes, the hoisting system is more suited to slinging beneath a conveyance. Comparing the performance of different ropes under specific Koepe or drum winder. The ropes stretch by about 51 cm as the skip is filled. New shoes were used for each test.

Privacy policy Terms of Use Terms of sale Contact. Lubrication of the main bearings is by a gravity feed from an overhead tank which can be filled by pumps. At the top of this page there is a picture of the Koepe principle, the corresponding explanations can be found here: On the rig are mounted several magnet operated relays in suitable positions see Fig.

The old rope is secured to the drum of the service winder and the used rope is removed from the shaft. Planning of work to allow maximum assembly at a location remote from the site, transport of large pre-assembled components.

The Chambers

The bridle, with the chain blocks attached, is driven down and stopped at the lower station elevation m below surface. Part I of this article Vector, April discussed shaft preparation; headgear superstructure; tail rope protection; underground skip loading; the installation of the lead ropes, and transferring the load to the Koepe wheel. It is essential that the tread grooves on the Koepe wheel be kept to the same diameter. The rope fixed under the pit cages for leveling out the different loads.

The purpose of this controller is constant control of the rate of retardation irrespective of any variation of load. Balanced friction hoists are not suitable for hoisting from multiple loading pockets on different horizons within a shaft, and are generally not suitable for deep shafts.


April 13th,Published in Articles: Hoist Headframe Winding engine Whim Man engine. The new head rope is clamped at the bank and the rest of it is removed from the service winder.

Two years later, once the technology had proved klepe and the Krupp Company demanded that Koepe surrender his patent rights, litigation between the two parties ensued.

The rock winder could only average 22 hoisting hours per day at an average of 28 trips per hour, the payload kooepe 11,2 tonnes being drawn from three loading positions in the shaft. This page was last edited on 21 Aprilat This operation was repeated for the other head ropes. Basic Search Advanced search options Archives. The ropes were mounted on steel trestles on the bank and wound sinder the rope service winder in turn. The head ropes and the bridle are lifted about 30 cm, to provide slack to enable the head ropes.

Following acceptance of the study, the decision was taken within a few weeks to implement it.

A straight type fully-open or fully-closed pneumatically operated quick discharge door is used for the measuring flask. The foundation for the Koepe winder was superimposed on the existing headgear and the Koepe winder was erected. The Koepe wheel is 5,8 m diameter. Reference with regard to availability. Winxer in cases of malfunction, deceleration has to be controlled, otherwise rope slippage would occur.

To each of the four 27 kg rails were arranged as shown in Section M — M of Fig. Clamping and lifting device CLD 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.

Other steel top-hat guides Uallow spillage to build up joepe provide a cushion for falling spillage. They are situated at each end of the drum shaft, between a main bearing and the motor armature as shown in Figs.

The tall ropes are attached to the bridle tailpiece by means of sealed ball-bearing swivels and straight wedge-type cappels. Drum hoists require rapid fluctuations in power demand, which can pose a problem if power is generated on site rather than provided through the main power grid.

Deep Mining, Rope Service Life and Performance Evaluation

If the winder fails to respond to the signal initiated by a relay of the helical controller, koepd not retard and is running at overspeed, the Ardic controller trips the safety circuit and the winder must retard at a rate defined by the magnetic amplifiers and come to rest.


The cappels is connected to the bridle. It is necessary to shorten the head ropes from time to time due to rope stretch. This Koepe winder has operated satisfactorily since its commissioning in Marchfor the hoisting of mineral and has augmented the capacity of the shaft considerably.

The rope is disconnected from the bridle in the headgear, passed over the Koepe wheel and lowered to bank level by means of the kospe winch A. Besides, with this type of skip, the carrying frame or bridle which takes the load and rope forces, is separate from the actual payload container or tub which is filled with ore.

Comparison of the technical data, design, and availability of the planned machinery with reference plants.

During cycle, these rotation deformations are associated with tension – tension fatigue. Unless the skip is in the correct loading position, an interlocking magnetic contractor prevents the discharge door from being opened. The installation of a Koepe winding plant at a working shaft: Statement of the investment and operating costs.

It is situated below the Koepe wheel and is set winnder the point of the tool on the centre line winde the drum shaft as shown in Fig. It was therefore necessary to arrest the upper and lower conveyances and the moving rope system. Extensive acceptance testing in workshop to allow fastest possible start-up on site. This type of singlepoint suspension is designed to facilitate winrer and calibration. The winder foundation of reinforced concrete accounted for tonnes of the winfer weight.

Device for lifting and supporting the drum shaft. A carriage mounted on rollers and holding a permanent magnet is rotated round the centre thread, guided by two vertical rods driven from the winder drum shaft. The concentric design of the friction pulley and the motor connection as well as the symmetrical design of the winder guarantee long-term stability of the entire drive system.
