Getting a grip - Atlas Copco's new magnets
13 February 2014
Two new Hydro Magnets, aimed at the recycling, scrap and demolition sectors, have been launched by Atlas Copco to complement its range of hydraulic attachments. Each model is available in two versions as either a fixed (F) or mobile (M) unit. Load capacities range from 280 kg (616 lb) up to a maximum of 7,500 kg (16,500 lb)
Hydraulic power provides automatic flow and pressure control through the use of a state-of-the-art flow divider. According to Atlas Copco, a high activating voltage rapidly achieves the magnetic power to attract a large volume of ferrous material and hold it firmly in place. When it comes to letting the material fall, a shock alteration of the polarity accelerates demagnetisation, resulting in fast material drop and a magnet plate free from even the smallest pieces.
An electronically generator is made from corrosion free alloy and has a digital control device in a waterproof body. Digital generator control technology gives a magnetisation and demagnetisation process cycle that is up to 25% shorter than conventional magnet controllers, leading to lower fuel consumption. It also protects the magnet against the risk of damage resulting from short-circuiting, overheating or excessively high or low revolutions of the generator.
