New Atlas Copco MG 1900 Grapple
"Whatever gets between those grapples is held absolutely tight" is what Abram Block, excavator operator of Messrs. Hagedorn GmbH from Gütersloh, a town in North Rhine-Westphalia in Germany, is saying about the new Atlas Copco MG 1900 Multi Grapple. He was testing the unit which is part of a completely new series of grapples and was very pleased with its performance. "The work can be easily surveyed, the grapple gets into every corner, the power, and the jaw opening to grapple width ratio is also OK", said Mr. Block.
With the MG 1900 from the Essen-based Atlas Copco Construction Tools the engineers are resolutely pursuing their objective to reduce the number of movable parts, thus minimizing possible sources of malfunctions, cutting down the maintenance costs and reducing downtime for the operator.
One of the logical consequences of this orientation is the concept of using only one central hydraulic cylinder to reduce possible malfunction sources and improve reliability.
The grapples have a straightforward design and plates with elongated holes to prevent the rubble from getting stuck. The two cutting blades on each side can be easily and quickly reversed 3 times. Amply dimensioned bearings provide a stable support and ensure minimum wear.
The housing, too, has been modified. Its simple but sturdy design gives the multi grapple the robustness it needs for heavy work.
And the rotation gear has also been improved. An oil directing plate integrates both connections so that hose couplings are no longer needed inside the rotation gear.
The MG 1900 replaces the MG 2200 D in Atlas Copco's lineup. It has a service weight of 1900 kg and a 350 bar static end pressure to better match modern carrier units in the 20-30 t class.
