A hybrid mobile operating machine comprising a motor vehicle driven by an internal combustion engine, an articulated arm associated with a pipe, a pumping unit and a stabilization unit, primary services and auxiliary services, wherein the internal combustion engine is suitable to power at least a first and a second power take-off. The mobile operating machine is provided with both a first drive unit which comprises at least one electric accumulator, a first electric motor and a first hydraulic pump, and a second drive unit which comprises at least one second electric motor and a second hydraulic pump.

Hybrid mobile operating machine and its functioning method

Telescopic arm for a crane for lifting loads, which comprises a first tubular segment, a second tubular segment located in the first segment and extractable with respect to the first segment along an extraction axis (X). The telescopic arm comprises a clamping device configured to axially and selectively clamp, along the extraction axis (X), the first segment and the second segment. The clamping device comprises a clamping seating provided in the first segment and a clamping pin associated with the second segment, sliding along a sliding axis (Z) transverse to the extraction axis (X) and able to be selectively inserted in the clamping seating.

Telescopic arm for crane and crane comprising said arm

A method to manufacture a tubular element for transferring abrasive materials such as concrete, inert materials or suchlike, wherein the tubular element comprises an internal tubular component made of chromium carbide or other wear-resistant material, and an internal tubular component in contact with and coaxial to the internal tubular component and made of composite material.

Tubular element to transfer abrasive materials, in particular concrete, and method to manufacture it

A method to make a tubular element to transfer abrasive materials such as concrete, inert materials or suchlike, where the tubular element includes an external tubular component made of steel and an internal tubular component, coaxial to the external tubular component, where the internal tubular component is made of chromium carbide, or other similar material resistant to wear.

Method to make an arm in a composite material for articulated or telescopic modular structures for the distribution of concrete, which comprises a first step in which one or more layers of fiber () are distributed on the external surface () of a male-type mold () having a cross section defined by at least a substantially flat wall. The section of the male mold () reduces, in at least one of its sizes, passing from one of its ends to the other. The fibers () may or may not be pre-impregnated with a resinous matrix. The method also comprises a second step in which the male mold () is ejected from the product thus obtained, a possible heat treatment being provided, for example in autoclave, before the extraction of the product.

Auxiliary extension device for a crane provided with a telescopic extendable arm having at least one end segment provided with a free end, wherein the auxiliary extension device is made of one or more composite materials.

Auxiliary device for a crane and crane comprising said auxiliary device

Segment of an articulated arm made of composite material, with an elongated shape defining a longitudinal axis, and having a box-like cross section. The segment includes a first end portion, configured for the pivoting of a further segment, a second intermediate portion configured for the pivoting of an actuation member, and a third end portion. The first, second and third portions are made in a single body. The second intermediate portion includes a protruding zone defined by a first side and by a second side converging with respect to each other to define a top. Pivoting elements are provided in the protruding zone for the pivoting of the actuation member between the protruding zone and the first end portion. The first and the second side defining the protruding zone are filleted to substantially rectilinear adjacent tracts of the first and third end portions.

Segment of an articulated arm and articulated arm comprising said segment

An arm made of composite material, and relative production method, consisting of a plurality of articulated segments with a longitudinal main axis (x), pivoted to each other, each of the articulated segments comprising a box-like structure and at least a joint element attached thereto by means of gluing, the box-like structure having an end cooperating with an end of the joint element on the inside of the surface of the joint element. The ends define a substantially conical reciprocally overlapping area and have profiles concordantly inclined by an angle (&#x3b1;) with respect to the longitudinal axis (x).

Arm made of composite material and relative production method

An arm to distribute concrete comprising a plurality of articulated segments selectively able to be folded back and extended with respect to each other, made of composite material, wherein at least one of said segments comprises at least a first tract and a second tract, each having a constant cross section, wherein the section size of the first tract is different from the section size of the second tract, a connection tract being provided between said first tract and said second tract.
