BASICS IN STACKER RECLAIMER

Wagons on Transfercar! This conceptual 3D animation video from my archive shows the effective utilisation of space.

Video of s hifting a Bucket Wheel Stacker cum Reclaimer machine (400t monster) from one bay to another bay by a Transfer Car. Single machine is used in multiple bays. One of my successful projects!

Is it possible to provide a 3/4 undercarriage support instead of 3/3 undercarriage support for the machine which is operating on an offset yard conveyor? The answer is ‘ YES ’ . Integrate a  BWSR/Stacker machine which has 3/4 undercarriage support an offset yard conveyor . SOLUTION: By providing a 3/4 undercarriage support we will face the following problems, 1. Feeding the material from the boom conveyor to the yard conveyor during reclaiming operation. 2. Feeding the material from the yard conveyor to the boom conveyor during stacking operation. 3. Feeding the material from the tripper to the intermediate conveyor.   Let us discuss the solution in 3 parts. a. Undercarriage WITH inclined chute. b. Intermediate conveyor WITH a tilt. c. Tripper a. Undercarriage WITH inclined chute Below figures show 3/4 undercarriage support machine on an offset yard conveyor. An inclined chute with proper valley angle (see the below figure) feeds the material from the boom c

I n any Bulk Material Handling Plant, when the raw material enters and leaves the Stock Yard from the same Junction Tower, ARTICULATED TYPE TRIPPER is provided in the Yard Machine. (Articulated type tripper arrangement is one of the 2 types of tripper arrangement used in any Bucket Wheel Stacker Reclaimer machine which is suitable for this layout requirement. The other type of Tripper arrangement suitable for this layout is SCISSORS TYPE TRIPPER. I will be writing an article on Types of Trippers & By-Pass arrangements separately ) In addition to Luffing Cylinders, Articulated Tripper needs one more set of Hydraulic Cylinders for its articulating operation. In a Bucket Wheel Stacker Reclaimer Machine, the luffing cylinders are mounted on the Slewing Structure (Slew Platform) whereas the cylinders for articulated tripper is mounted on the Non-Slewing Structure (Tripper). Hydraulic Piping to be done for both sets of cylinders. For the operation of these two sets of Hydraulic Cylin

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.

This title always flashes in every Mechanical Engineers mind along with the answer “HYDRAULIC DRIVE”. Is this true? If this is true, then to what extend? Let us discuss in brief! No doubt that comparing Electro Mechanical drive with Hydraulic drive is like comparing a Conventional car (which runs on Petrol/Diesel) with a Tesla car.  Still Conventional car has advantages over a Tesla car. In the same manner, Electro Mechanical drive has advantages over Hydraulic drive as mentioned below: 1.    Commercial -       Price of Electro Mechanical drive is much lesser than Hydraulic drive 2.    Installation -       Electro Mechanical drive is easy to install and needs less time to install, whereas installation of Hydraulic drive needs EXPERTS and time consuming one. Pickling of Hydraulic Pipes consumes more time and NAS (National Aerospace Standard) value of the oil to be guaranteed as per the standard before commissioning the Hydraulic drive. 3.    Maintenance -
