Compact and Powerful Hydraulic Actuators

As the name suggests, the hydraulic power unit, based on Pascal’s law of dynamics is the main driving component in a hydraulic system. It consists of a motor, a reservoir and a hydraulic pump. Their synchronised action even in a mini hydraulic power unit generates ample power to stir up motion and drive the hydraulic ram. This space saving vertical style device is designed for quiet and leak-free operation.

These power units generate power as per the pressure exerted on a specific area. With a wide range of applications, these are designed depending on the ultimate utility and manufactured. To illustrate this aspect, the Delhi NCR based Dantal Hydraulics is one of the leading Indian companies engaged in the development and fabrication of such silent and leak-free operation power units. Apart from customised applications, the Mini Compact Power Packs produced by this company are extensively used in systems like – Read more

Amazing Action of Hydraulic Cylinders

This is a true story of an inquisitive journalist. Watching an off-shore rig of Oil and Natural Gas Commission (ONGC) on the Bombay High during early 1980s from a helicopter or aboard an OSV (off-shore supply vessel) was a delight for him. He would grab every opportunity of visiting Sagar Samrat and another rig as and when the occasion arose for coverage in the magazine for which he was the correspondent in Bombay.

He used to wonder as to how such an expansive platform was hoisted and placed on the mammoth jacked up rigs in the middle of the sea with the anchor winches operating round the clock by turns. And then came the day in late 1982 when a gigantic rig assembled at the Robin Shipyard in Singapore was towed and tugged by several barges to Bombay.

All this while, this journo’s inquisitiveness grew with each passing day and after covering the event of formal induction of this new rig from Singapore, he sought an exclusive visit by an OSV to watch its commissioning that was to take place a fortnight later. Three weeks later, he was thrilled to receive a telephonic call from the PR Manager as well as an invitation from the Director of Engineering to watch the commissioning of the new rig. Read more
