Many construction companies are opting for redevelopment, renovation and urban reuse in the absence of new build opportunities. This often involves the total removal of obsolete buildings of no historic or artistic value.

MB Crusher’s MB G-900 is one of the items of equipment currently being specified for selective demolition. By mounting it on to the excavator, the impact of the demolition is minimised in terms of both the noise and dust produced.

The grapple, designed by MB Crusher in Fara Vincentina, Italy, weighs 780 kg (1,720 lb) and can be mounted on excavators with operating weights between 12 and 18 t.

It has a capacity of 0.43 cu m with closed claws and is said to combine agility with a strong clamping force, allowing easy masonry demolitions.

The closing pressure, depending on the settings, can go from 200 to 400 bar with a flow rate of 30 l/min of oil per minute, while the rotation flow is up to 20 l/min.

Design features of the grapple, which is one of four models in the MB range, include an inclined plate connection that considerable increase the range of action of the grapple, and the continuous movement at 360° allowing the operator maximum working versatility.
