Cable Routing methods from Non-Slewing to Slewing Structure

-

In Slewing type Yard/Port machines, except Travel Drive all other drives viz., Bucket Wheel, Slew, Luff & Boom Conveyor are mounted on the Slewing structure of the machine, whereas the Electrical House is Mounted on the Non-Slewing structure of the machine.

This article is about various Electrical Cable Routing methods from Non-Slewing structure to Slewing Structure of the machine.




1. SWIVEL TABLE

Cable from Electrical House is taken to the Slewing Structure through Tripper. From Tripper (Non-Slewing Structure) to Pylon/Boom (Slewing Structure) by the Swivel Table arrangement.



2. CIRCULAR FESTOON

Cable from Electrical House is taken to the Slewing Structure through the Under carriage and then to the Slew structure by means of Circular Festoon arrangement.


3. ENERGY CHAIN

Cable from Electrical House is taken to the Slewing Structure through the Tripper by Energy Chain arrangement. Energy Chain arrangement is mounted between the Tripper discharge and the Slew Structure. 



4. SLIP RING

Slip Ring is mounted between the Non-Slewing & Slewing Structure. Slip Ring is the only available solution for the machine with 360° continuous rotation (Example – Circular Stacker).


5. CABLE LOOP

Cable from Electrical House is taken to the Slewing Structure through the Under carriage and to the Slew Platform just by forming a ‘Loop’. Care to be taken, else cables will entangle with the Yard Conveyor Belt Sway Switch / Self Aligning Carrying Idler Rollers. In general, this method is NOT PREFERRED by customers.



TO CONCLUDE, EXCEPT CIRCULAR STACKER MACHINE WITH 360° CONTINUOUS ROTATION (Slip Ring is the ONLY option), FOR ALL OTHER SLEWING MACHINES, SLEW ANGLE, LAYOUT RESTRICTIONS & CUSTOMER REQUIREMENT ARE THE FACTORS WHICH DETERMINE THE CABLE ROUTING METHOD.

Stockpile configuration

  To run any plant continuously, the basic requirement is the continuous supply of raw material. For example, to run a Thermal power-plant  or Steel plant or an Alumina plant, continuous supply of the raw materials viz., coal / iron ore / bauxite / limestone is required. Unfortunately, it is difficult to guarantee the continuous supply of raw material due to various factors viz., availability of raw material, transporting the raw material (by ship, wagon etc.,) or force majeure. Hence the solution is to store more than the required amount of these required raw materials in the plant itself. ‘Google’ defines stockpile as, ‘a large accumulated stock of goods or materials, especially one held in reserve for use at a time of shortage or other emergency’. Why the raw materials to be stacked and not dumped? It is because of the following limitations, ·        availability of space ·        quant...

Trapezoidal stockpile Vs Trapezoidal stockpile

Trapezoidal stockpile can be formed in the following two methods, 1.    Without compensating the travel length of the machine. 2.    By compensating the travel length of the machine. Each method has its own advantage and disadvantage. Before comparing the advantages and disadvantages, let us discuss how a trapezoidal stockpile is formed. Without compensating the travel length of the machine: The above figure shows a trapezoidal stockpile formed without compensating the travel length of the machine. By compensating the travel length of the machine: The above figure shows a trapezoidal stockpile formed by  compensating  the travel length of the machine. Travel length compensation: To understand travel length compensation, first let us discuss how a triangular stockpile is formed with the help of a stacking mode drawing. (Stacking mode drawing: Is the drawing which defines the slewing angle, luffing angle and the...

Stockpile end cone correction

Consistency is an important and inevitable factor in any process plant. To meet a consistent quality output of the product (for example steel or cement) the raw material shall be fed continuously for processing in the required ratio. Consider a case in which the raw materials are stored in the stockyard in number of layers and during reclaiming if the consistency in blending is disturbed after sometime of reclaiming. The result will be change in product quality. Case study: Form a stockpile of 40m (Width) x 12m (Height) x 250m (Length) with 6 layers and discuss the consistency (mixture of all 6 layers of material) during reclaiming operation. Machines used for stacking & reclaiming, Stacker       - Luffing Stacker or Twin Boom Stacker Reclaimer   - Bridge Scrapper Reclaimer or Barrel Reclaimer or Wheel on Bridge Reclaimer (Note: above mentioned reclaimers are with harrow arrangement) STOCKPILE: Below sketch shows a stockpile of 40...
