HYDRAULIC LUFFING Hydraulic cylinders and power pack do hoisting or lowering of the bucket wheel boom. with gear unit and swing switch. which is of welded plate construction. economics solutions can only be achieved by the use of combined bucket wheel stacker reclaimer. The cable reeling drums are suitable to pay out the cable in both the direction from the central feeding point. BUCKET WHEEL The bucket wheel is cell or cell-less and fitted with replaceable buckets. SLEWING MECHANISM The slewing mechanism has direct current drives/ vvvf drives. which ensures stability and guarantees an even distribution of load over the entire assembly. Elecon bucket wheel stacker reclaimer machine can stack the material to form the stockpile or reclaim the stockpiled material and feed onto the main line conveyor. Bucket wheel drive gear is of spiral bevel helical or planetary design. THREE-POINT SUPPORT The lower carriage is of sturdy box type design and is supported on the travel mechanism. are provided on the lower frame. BUCKET WHEEL BOOM The bucket wheel boom is of sturdy welded plate construction or lattice girder construction. . BELT WEIGH SCALE Electronic belt weigh scale is provided optionally on the boom conveyor to measure the flow and also to regulate the reclaiming capacity of the stacker-cum-reclaimer.Wheel on Boom Reclaimer with 40 meters Boom Length handling Iron ore at 4000 MTPH capacity at izag Port Trust For continuous stacking an reclaiming of crushed bulk materials. The speeds of these motors are variable over a specified range controlled by a potentiometer provided on control desk with the sector-wise position left -O. The bucket wheel drive is reversible type to facilitate withdrawal of wheels in the event of excessive under cutting. is supported on ball bearing/roller bearing slewing ring. It has statically determined three points support.right. Slewing rang is ± 105 degrees. POWER AND CONTROL CABLE REELING DRUMS Motorised cable reeling drums. The super structure. The upper and lower positions of the bucket wheel boom are limited by control and limit switches. A Fluid coupling is provided between the motor and the bucket wheel gear. Travel drive is provided with spiral bevel and helical gear units of dust proof construction with gear casings of fabricated steel Cast-Iron. complete with suitably rated contorque drive motor. resistance boxes. ELECTRICAL EQUIPMENT AND CONTROLS FOR STACKER. in all climates and under all conditions. cable reeling drum. Various mode of controls exists to meet stacking and reclaiming systems.RECLAIMER The stacker-reclaimer machine must run reliably and without interruption. HT switchgear. special type of safety and operational monitoring devices. the alarm/trip signals in the control systems of the machine activate the audio/visual Signal to the machine operator in the operator's cabin. Stacker-Cum-Reclaimer in Operation at Thermal Power Station of Maharastra State Electricity Board . In case of reversible stacker-cum-reclaimer. dusty. LOCKING ARRANGEMENT Adequate locking arrangement is provided between the super structure and lower structure to make the machine withstand storms and cyclonic winds. WIND WARNING DEVICE The Elecon stacker-reclaimer machine is provided with wind warning device. Air-conditioner unit is installed on request. When the velocity of wind exceeds the set value. Electrical equipment includes large range and type like HT trailing cable. indications. vibration and jerks. The operator thereby applies the rail clamps and Stops the travel movement of the machine. variable speed AC. with the provision of a tripper car. Control Panel for the entire electrical equipment is also provided. AUTOMATIC OPERATION Stacker-cum-reclaimers can be designed for unidirectional flow or instantaneously reversible flow depending upon the application. wind warning alarm and protection (optional) etc. The recognition of these circumstances has formed the basis for the design of the electrical equipement for Elecon's stacker-cum-reclaimer. etc. ease of maintenance. material is conveyed in the same direction as It was stockpiled (this is done by reversing the main line conveyor).
