Samudal Rope sheaves Each set of rope sheaves on the headgear is mounted by means of anti-friction bearings on a stationary axle. The dimensions of sinking equipment had become larger and the total weight of kibbles, ropes and multiple deck sinking stages amounted to about tonne.

At present, the average daily hoisting time is 18 hours. Spillage from the loading flask is negligible if the skip positioning magnets are located accurately.

The permanent ladder way in the shaft provides access to the headrope cappels. Koepe winder Full speed is maintained constant to the beginning of the retardation period Point Birrespective of load. Device for lifting and supporting the drum shaft. The Koepe winder was used to release No. Underground mining Vertical transport devices Winches. A rail traverser was installed for the quick positioning of the conveyances on the bank.

Downtime for maintenance can therefore be kept to a minimum by having tubs in reserve and the capacity to reline worn tubs while hoisting kkepe continue. Test machine capabilities are: 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. 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.

Fire-setting Gold panning Hushing. To guide the skips in the shaft on ropes to minimise the windrr installation work in the shaft. Two years later, once the technology had proved successful and the Krupp Company demanded that Koepe surrender his patent rights, litigation between the two parties ensued.

Koepe winder Article about Koepe winder by The Free Dictionary If you imagine the rope at the top, the both pit cages and the rope connecting them at the bottom, you can nearly see a circle.

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. Rollers attached to the bottom door of the pan run over profiled horns attached to the bridle to op the koee. This operation was repeated for the other head ropes.

The bridle is now directed into the guides and hinged guides are closed and secured. The Koepe wheel is 5,8 m diameter. Simulaiton of the dynamic loads. When mounting a block on the rail, its braking or friction components, namely the cast iron and phosphor bronze wearing slippers, are pressed against the rail head by the tightening action of the four 2,5 cm diameter securing bolts with springs on the outer cast steel body pieces, so the block can absorb impact by friction.

The Ardic controller supervises the retardation of the winder only and shadows the helical controller by a cam and follower system. The steelwork for supporting the clamp was then removed and the Koepe winder used to free the clamps on the tail ropes. The ore pass control chute is fitted with a pneumatic radial cut-off door.

This was connected with the disadvantage that — with heavy loads in the pit cages and especially in the inner windings — a great strain was effecting the ropes, because they were winded up very tight. These crane units each have two control panels. The Chambers Reference with regard to availability. Two tonne hydraulic jacks raise and support the drum shaft.

Determination of the discardign critera for ropes under deep shaft condiitons and magnetic windre 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 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. Comparing the performance of different ropes under specific Koepe or drum winder. The skip cannot be hoisted unless the measuring flask door is dosed and locked in position. Lifting cylinders allow the maximum operating load to be lifted by 1.

May 15th,Published in Koele In case of defect or malfunction, this reserve channel is immediately ready to take over the function of the defective channel.

April 13th,Published in Articles: The ropes were mounted on steel trestles on the bank and wound onto the iwnder service winder in turn. The installation of a Koepe winding plant in a working shaft Part II — EE Publishers The head ropes and the bridle are lifted about 30 cm, to provide slack to enable the head ropes. The underground bridle is now moved to the station level and the final tensioning of the new rope is carried out.

The winder foundation of reinforced concrete accounted for tonnes of the superimposed weight. Arrangement for attaching the chain block to the cappel. Set-up for shortening a head rope. The winder drum is rotated to lift the new bridle and tail ropes.

This means that the availability of the system is not affected while damage of this kind is being repaired. TOP Related Articles.

The diodes need, according to the datasheet, a minimum of 20 uA to operate. Enric Blanco 4, 5 11 However, at 4V voltage drop, the 10k resistor can only provide 0. However when I measure it, OUT is only 2. When the voltage is less than 5V they can be neglected. Andy aka k 10 Email Required, but never shown.
