Product Description :
With increased cost of land and construction of built up area, industries requiring to stock substantial volumes of their products or inputs, especially if they are diverse and palletized, are looking into material handling systems which maximize utilization of warehouses by volume instead of by floor area, besides of course swift retrieval and stocking. This concept has become urgent in metros and mini metros, with spiralling cost of land and construction.
The above has been traditionally achieved by Fork Lifts, either battery or diesel operated operating in conjunction with an appropriately designed racking system. This method has the following disadvantages.
Electromech Engineers has developed Double Girder Stacker Cranes overcoming all above drawbacks. Essentially a stacker consists of -
1.A pair of Main Girders spanning the entire ware-house with cross travel rails mounted atop.
2.A pair of End Carriages on which the Main Girders rest.
3.A motorized trolley moving along the main girders with a sub-trolley mounted atop the main trolley. The sub-trolley has a hoisting mechanism that can also rotate about its own axis.
4.A rigid fixed mast suspended from the sub trolley.
5.A movable mast with adjustable forks running on the fixed mast on rollers.
•Exhaust fumes if diesel Fork Lifts are employed
•Battery charging station if battery operated Fork Lifts are employed
•Specialist maintenance crew for both
•Limitation in storage by height (limited by fork travel) reducing storage space by volume
•Increased aisle width (consequent to turning radius of the fork lift), reducing storage space by area.
