MB grapples built for demolition to minimize noise and dust
The latest MB Crusher grapple model MB-G900 weighs 780 kg, is built in Fara Vicentino-Italy, and is designed to be mounted on excavators with operating weights between 12 and 18 tons. These attachments are ideal for use in IC&I and C&D recycling applications, and are designed to minimize demolition impact, both in terms of noise and dust. The MB-G900 has a capacity of 0.43 cubic meters with closed claws and combines remarkable agility and strong clamping force, which allows operators to easily carry out demolition tasks, including masonry demolition. The unit's closing pressure, depending on the settings, can go from 200 to 400 bar (with a flow rate of 30 liters of oil per minute), while the rotation flow is up to 20 liters per minute (from a minimum of eight ).
According to MB Crusher, the MB grapple series is extremely responsive and allows for precise selection of materials in demolition applications. The "graduality" with which it can manage closing forces allows for very efficient recyclable materials handling of wood and metal, and all recyclable materials can be efficiently separated from those intended for landfill while at the same time operators can demolish materials including masonry which can then be transformed into recovered raw materials.
The model MB-G900 grapple has many design features that enhance performance, including an inclined plate connection that considerably increases the range of action of the grapple, continuous movement at 360°, allowing operators to always have the maximum working versatility to get the job done.
Particularly sturdy (built of Hardox steel), the MB-G900 claw's side supports are heavily reinforced and feature an optimal claw shape and wide opening (up to 540 mm) that allows recyclers to move a great deal of material. In addition, maintenance and upkeep is very simple, with easily accessible greasing points.
In addition to the MB-G900, MB has three other models of grapples, all with the same design and construction features:
1) The smallest model, the MB-G600 is designed for machines up to 12 tons, essentially mini- and midi-excavators or backhoes, and has a capacity of 0.29 cubic meters with closed claws.
2) The MB-G1200 comes in a capacity of 0.71 cubic meters (with closed claws) and is suitable for excavators with operating weights between 18 and 25 tons.
3) The largest model of the MB range is the MB-G1500, at 2-tons weight, which guarantees a capacity of 1.43 cubic meters with closed claws, a closing pressure between 300 and 400 bars and an oil flow rate corresponding to 50 liters per minute. This latter grapple is marketed by MB for excavators weighting from 20 to 25 tons and, like all other models in the range, has interchangeable claws, a safety valve (which keeps the claws closed in case of oil loss in the circuit), a silent block that completely eliminates the "clang" normally heard when clamps are opened completely, and all units are designed for simple, easy maintenance.
