Turn your neck around and you will observe applications of hydraulic engineering in one form or the other. For instance, in India’s national capital region of Delhi, the network of metro rail and scores of flyovers have become the index of the city’s skyline. And manual erection of a single pillar would have entailed tens of thousands of man-hours whereas it was possible to achieve the same in a fraction, both in terms of time and money. The credit for such an execution of the task goes to hydraulic solutions.
Yes, hydraulic applications in various forms and through different gadgets and machinery enabled the erection of a pillar, right from excavation of the earth and laying of pile foundation to transportation of the huge pre-fabricated concrete slabs and girders to the particular site from elsewhere and hoisting them atop. If you reckon the entire erection stage-wise and compute the overall time including the cost, don’t be surprised to learn that for a particular pillar, the cumulative break-up of the process may not exceed more than 60 to 75 days in toto.
In other words, the combined power of cylinders, motors and pumps in a hydraulic system is tremendous and almost unbelievable. This technology has been a boon for a car parking system manufacturer. Among the Indian companies in this segment of industry, the Delhi-NCR based Dantal has designed and developed economical and yet advanced car parking solutions. These systems are exported too.
Hydraulic lifting and lowering techniques are used to park two cars one above the other. One of them is classified as Puzzle Type. As the name suggests, it is lateral and vertical movement of platforms to accommodate multiple cars in a puzzle like structure! The other types are known as Automated, Semi-automatic, Multilevel, Dependent and Customised/Computerised electro hydraulic car parking systems.
