Abstract: A monitoring device and connected monitoring method are provided for monitoring an operating area of an operating machine. The operating machine includes a work member and support and movement means for the work member. The monitoring device includes at least an optical recording unit able to acquire images of the operating area surrounding the work member. A management unit is configured to receive and process the images and to send a command signal to the work member when an obstacle is detected in the operating area. A positioning member is able to position the optical recording unit in relation to the position of the work member and in relation to the possible presence of one or more fixed and/or moving obstacles in the operating area.

Abstract: An excavation device having a pair of milling wheels with a substantially horizontal axis (X) of rotation. Each milling wheel peripherally equipped with an excavation apparatus to define an excavation front substantially parallel to the axis (X). The excavation device also has a chain-type transmission to draw in rotation, in a first operating condition, each of the milling wheels. The transmission is driven by a motor and provided, on its side which is external during use, with an excavation apparatus. The excavation device also has a thruster able to be activated to selectively move the transmission into a second operating position, widened and external with respect to the first operating condition.

Abstract: An automatic loader (10) for drill rods (11) adapted to be associated with a boring machine having a guide and drive assembly (12) for the drill rods (11) includes at least a store (13) containing a plurality of drill rods (11) and a movement assembly (14) that is able to selectively remove, one at a time, the drill rods (11) from the store (13) to position them on the guide and drive assembly (12). The movement assembly (14) is arranged in an intermediate position between the store (13) and the guide and drive assembly (12), so as to not interfere with the latter during the removal of the drill rods (11) from the store (13).
