Suretech Infrastructure offers a wide range of resonance free hammers, ideal for noiseless operation.
Suretech Infrastructure, the authorised dealers of ICE- Holland in Netherlands, offers a wide range of hydraulic vibratory hammers, resonance free vibratory hammers, excavator mounted vibratory hammers, earth augers and submersible dredge pumps. Suretech has been dealing with ICE vibratory hammers from Dieseko Group for the past 12 years and are proud to have supplied nearly 200 machines to the Indian customers. The hammers are ideal for noiseless operation.

The details
Conventional vibro hammers have a constant eccentric moment. When passing through the critical frequency area during start-up and stop, the constant amplitude causes disturbing negative vibrations in the boom of the crane and in the soil; not just at the spot, but with a considerable perimeter distance.

However, when making use of a resonance free vibratory hammer with an adjustable frequency of zero to a maximum of 2,350 revolutions per minute, critical vibrations in start-up and stop are eliminated. After passing the critical frequency area, the eccentric weights are automatically adjusted and synchronised to the current eccentric moment.

The process
It is not necessary to readjust the vibro hammer when stopped and re-started. The hammer will automatically select the last setting. Resonance free vibro hammers can even work next to dilapidated structures without causing any damage. The advantage of resonance free vibratory hammers is that these do not pass bad or harmful vibrations to the surroundings and thus can work in city centers and congested areas.

India To Boost US LPG Imports, Cut Middle East Reliance

India is planning to reduce imports of liquefied petroleum gas (LPG) from the Middle East as state-owned refiners prepare to ramp up purchases from the United States, according to sources familiar with the matter. The move aligns with New Delhi’s efforts to expand energy cooperation and secure a broader trade deal with Washington. State refiners have already notified their traditional LPG suppliers in Saudi Arabia, the United Arab Emirates, Kuwait and Qatar of the potential reduction in imports. Although the exact size of the supply cut was not disclosed, earlier reports suggested that Indi..

UK Sanctions Nayara Energy in Crackdown on Russian Oil

The United Kingdom has announced fresh sanctions on 90 entities, including Indian refiner Nayara Energy Limited, in its latest bid to curb Russian oil revenues and weaken President Vladimir Putin’s war funding. The sanctions, unveiled jointly by the Foreign, Commonwealth and Development Office (FCDO) and the UK Treasury, aim to disrupt networks supporting Moscow’s crude exports amid the ongoing war in Ukraine. According to the FCDO, the new restrictions are intended to “strike at the heart of Putin’s war funding” by targeting firms and assets that enable Russia’s energy trade. “..
