The latest complement to 161 Atlas Copco’s range of hydraulic attachments is the Hydro Magnet, a range of profitable tools for recycling plants, scrapyards and the demolition industry.

Hydro Magnets enable valuable iron and steel to be separated quickly and easily from concrete waste for subsequent recycling. Simply installed on the existing grapple or shear installation, they require no extra generator or electro cable on the carrier. Two Hydro Magnets are available in two versions, as a fixed magnet (F), or a mobile magnet with chain link (M). Load capacities range from 280kg up to 7.5tonnes.

In the Hydro Magnet, hydraulic power provides automatic flow and pressure control by means of a sophisticated flow divider. A high-activating voltage is said to rapidly achieve the magnetic power to attract a large amount of ferrous material and hold it firmly in place. A shock alternation of the polarity accelerates demagnetisation, resulting in fast material drop and a magnet plate free from even small pieces of steel.

The optimised weight/performance ratio and intelligent interaction between all integrated components in the attachment offers optimal handling performance. The overall result is a faster collection and loading process.

The electronically controlled generator is made of corrosion free alloy and has a digital control device in a waterproofed body. Atlas Copco’s digital generator control technology gives a magnetisation and demagnetisation process cycle that is up to 25% shorter than conventional magnet controllers. This, in turn, means lower fuel consumption. The digital control device also protects the Hydro Magnet against the risk of damage caused by short circuiting, overheating or excessively high or low revolutions of the generator.

All key components of the Hydro Magnet are integrated into a compact design and the magnet plate is made to handle rough environments. A hermetically sealed steel case protects the magnet coil against mechanical impacts and humidity, and an external Hardox steel ring protects against wear. The large steel surface compensates for temperature increases.

A multifunctional diagnostic panel in a waterproofed body indicates current working status and potential faults for trouble-shooting. No special maintenance is needed, apart from periodic control of the bolt connections and electro cable connection between the generator body and the magnet plate.

Collecting ferrous material remaining in the demolition bulk using Hydro Magnets not only means more profit, it also reduces risk of damage to crushers, conveyor belts, and other equipment. The high risk of tyre damage for trucks from rebars remaining on driveways on job sites is also substantially reduced by collecting them with Hydro Magnets.

    From 1 January 2018, the Hydraulic Attachment Tools division within Atlas Copco became part of Epiroc, the company that Atlas Copco plans to dividend out in mid-2018. From that date, all the division's current products will be delivered with Epiroc product branding. The division manufactures excavator attachment tools, such as hydraulic breakers, cutters, pulverisers, bucket crushers, shears, grapples and magnets. The company says that the hydraulic breaker was originally developed in 1963 by the German

    Atlas Copco is now offering an updated version of its proven QAS 60 generator that is designed to provide greater mobility. A smaller footprint allows for 12 QAS 60 generators to be fitted into a standard container. The firm has made the design more compact as this helps cut transportation costs for its customers, especially those in the rental business. The new QAS 60 is less than 2.4m long so it can be placed sideways on a truck. This allows more units to be carried on a truck and also ensures easier

    April 20, 2012
    Atlas Copco claims the angled shape of its two new hydraulic bulk pulverisers, available for carriers of 18 to 35tonnes, make them ideal for secondary demolition of reinforced concrete. The broad jaw of the BP 2050, BP 2050 R, BP 3050 and BP 3050 R machines ease the feeding in of material on the ground which, Atlas Copco (AC) claim, speeds up work and enables cleaner separation of rebar and concrete prior to their reduction into grain sizes suitable for crushing or use as back ll.
