Demolition grapples are heavy-duty hydraulic tools, designed for applications involving demolition of non-concrete structures and material handling.
Idrobenne’s DG demolition grapples are gripping devices formed by two tines in synchronous closing, put in motion by an hydraulic double-acting cylinder with non-return valve, with a single hydraulic circuit. The jaws’ tips touch each other at the end of the closing phase, so as to allow a very precise and firm grip on objects. These hydraulic equipment are conceived to perform small demolitions and to separate the resulting materials. Demolition grapples are therefore very useful where controlled demolition and separation of waste must be processed. Easy to use and versatile, the demolition grab for mini excavator is an increasingly popular tool, even on waste dumps and recycling sites. Idrobenne’s demolition grapples, which have a great structural strength and an enormous clamping force, are offered in eight models that can equip machines from a minimum weight of 2.5 tons to a maximum of 27 tons. Idrobenne also produces a line of similar equipment, with a lighter construction, intended for rapid selection of materials. These take the name of SG – sorting grapples – and are produced in 5 models, suitable for from 1.5 to 8 tons machines.
Unlike orange peel grapples, clamshell buckets and log grapples, which must be mounted on an hydraulic machine via a cardan suspension link (the so-called “pendulum mounting”, that allows the oscillation in the longitudinal and transverse direction), demolition grabs can be mounted by a rigid connection, which allows faster and more precise movements. The clamp operates as an extension of the excavator arm and ensures a great accuracy. On demand, Idrobenne can make or supply the adapters for the most common couplers like Caterpillar, Verachtert, Geith, Arden Equipment, Trevi, Vtn, Cangini, Morin, Lehnhoff and Volvo (nordic standard).
Idrobenne uses high-tensile steel for the manufacturing of structural parts of demolition grapples. On the other hand, the parts which come in contact with the material, such as the sides of the claws and the wear blades, are made of the best wear-resistant steel HB400. Bolt-on counter-blades are supplied as standard, included in the price, and are reversible. Every demolition grapple is supplied with a continuous hydraulic rotator as standard. Depending on the model, this can be provided by the German company Kinshofer, synonymous with high quality in orbital rotation systems, or assembled within the company. In the latter case, the rotator is composed of a very resistant slewing-ring wheel, with one or two rounds of balls, which is set in motion by a top-quality hydraulic motor Parker. The structure of DG demolition grapples is designed to offer maximum reliability, being built with a concept that combines structural rigidity with the minimum weight. In particular, models DG200 and DG250 are built with the so-called QUADRA-BOX system. It consists of a reinforced, very rigid frame, with oversized bearings in the joints of the claws. Even in this case, the design is simple and essential: a constructive criterion which facilitates routine maintenance and lifespan of the equipment. The entire Idrobenne production system is carried out under ISO 9001 quality certification.
Demolition grapples are offered in two versions: demolition and universal. The first, more popular, is the traditional version with metal ribs on the tines. The parallel metal ribs give the jaws a high structural strength while ensuring the operator a great visibility. The universal version, on the other side, has jaws with closed bottom, saw-tooth profile and ESCO-type digging teeth. All these differences are designed to make the grapple perfectly suitable for environmental architectures and tasks like formation of terraces, positioning of stones and handling of boulders. In the construction of dry walls, for example, the tines with saw-tooth profile and teeth allow a firm grip and a great accuracy in the laying of the stone, while the closed bottom of the clamps can perform like a clamshell bucket and allow the operator to apply a layer of earth between a row of boulders and the other. Thus, the sorting grapple "universalgreifer" version combine the features of a clamshell bucket with the precision movement of a demolition grab. These hydraulic tools, thanks to their versatility, are very common in mountainous regions such as Austria, Switzerland and the Italian region of South Tyrol, where Idrobenne faces with other brands like Martin and Huppenkothen. These equipment are genrally mounted on spider excavators type Eurocomach and Menzi Muck.
Idrobenne demolition grapples are very robust and can equip most of the construction equipment for rental, such as excavators, telehandlers and wheeled excavators. Given the quality of materials and the reliability of the design, it is not difficult to find a used demolition grab. In particular, the company based in Isorella (Brescia) can offer pre-owned grabs for mini excavator, the most of them overhauled, with guarantee. The price of second-hand demolition grab can be really competitive. Looking for a used grapple could be a good deal. Idrobenne has a repair shop and, most important of all, has ready on stock spare parts for every hydraulic equipment. Idrobenne’s demolition grapples for mini-excavators have low prices; do not hesitate to ask for a demo video. Last but not least, the Company can build adapters for the most common hydraulic quick couplers. Ask our after-sale service.
