MB Crusher introduces three new excavator grapples
September 22, 2021 By Rock to Road Staff
MB Crusher has developed three new grapples for small, medium and large excavators.
Mini and midi excavator grapples
Two of the new grapple models, the MB-G350 and the MB-G450, are designed for smaller excavators.
The MB-G350 weighs 187.4 pounds and is compatible with mini excavators weighing from 2,600 pounds to 5,200 pounds.
The MB-G450 weighs 644 pounds and can be installed on midi excavators weighing 6,000 pounds to 12,000 pounds.
Both grapples have a very wide opening – despite being small, they can still pick up and handle large materials. They are equipped with a fall prevention valve to ensure safety. The parts prone to wear are made of Hardox steel.
Both models are designed to have an electrical kit installed for dual-acting hydraulics – this way, the two grapples can use 360-degree rotation even with mini excavators that only have two hoses.
Like the larger models, the MB-G450 sorting grapple comes with interchangeable blades, which can be flipped around, extending the life of the blades. Both units have two versions: with or without a rotation turret.
Both can also have accessories installed to simplify managing materials – the clamshell kit to collect and handle small material such as soil, gravel, and sand, and the multi-purpose blade kit to pick up oddly shaped materials.
For the MB-G450 sorting grapple, you can install the tilting lift rubber protection kit to manage angular blocks and delicate material.
Heavy-duty excavator grapples
Weighing at 3,560.47 pounds and with a load capacity of 0.44 m3 /440 L for versatile, compact and reliable equipment, the new MB-G1000 grapple was explicitly designed for heavy work. Due to the work, the unit has been reinforced without losing its agility and ease of use.
There are two new features that are now the standard: the dual motor, which allows for greater rotation and closing force, and the balancing valves installed on the hydraulic cylinder, allowing the unit to be more precise when handling materials.
This new model also comes with an inclined plate, allowing the unit to work regardless of the angle, and has the 360-degree hydraulic rotation, allowing the grapple to pick up materials in all working conditions efficiently.
It’s also equipped with a safety valve, preventing accidental openings if the excavator’s pressure drops. There’s also a silent block, allowing the unit to work in areas where one must be mindful of the noise.
Depending on the work, the MB-G1000 model can be equipped with various accessories: the grip improvement kit for the blades, allowing the unit to handle materials with a better grip and greater control, perfect for materials of particular weight and shapes.
The multi-purpose blade kit consists of a double blade: one side has teeth while the other is smooth. Another accessory is the tilted lift rubber protection kit, which handles angular block or delicate material.
Lastly, there’s the clamshell kit to collect and handle small materials.
