Abstract: In the field of hoisting and controlling hoisted loads, a hoisting device for hoisting a load includes a support beam, two load carrying units, structured to be slid along the support beam and being structured to hold the load, at least one counterweight structured to be slid along the support beam, at least one sensor capable of measuring the weight force held by the load carrying units, a first driving unit structured to slide the load carrying units, a second driving unit structured to slide the counterweight, a third driving unit structured to hoist the load, a hooking point structured to be hooked from a crane, and a processing unit structured to receive the information produced by the sensor and structured to operate the first driving unit, the second driving unit and the third driving unit.

Abstract: An apparatus for hoisting and positioning a load in a self-balanced manner regardless of the position of its center of gravity. The apparatus comprises an upper platform adapted for being hoisted from a general hoisting point, a lower platform adapted the attachment of a load to be hoisted and positioned, and a six degrees of freedom actuator comprising six variable length tendons, adapted for moving the lower frame with respect the upper frame in the three directions of the space and tilted around the three axis of the space. A configurable counterweight system supported by the upper platform is arranged for modifying the center of mass of the apparatus over a horizontal plane, and processing means are configured for dynamically calculating a desired position of the counterweight system, for balancing the apparatus with the respect to a general hoisting point.

Abstract: The invention relates to a solar tracker having oleo-hydraulic cylinders that increase the rigidity of the system by keeping the two chambers of each cylinder pressurized, even while on stand-by. This makes the system more accurate, avoiding undesirable cylinder movement caused by oil compression. The system includes a circuit having at least one cylinder assembly (8,9), an oleo-hydraulic plant and a control system (5), wherein the oleo-hydraulic plant supplies the oil to the cylinders controlling the speed of movement of these latter, and the control system (5) supervises and controls the correct operation of the entire system and protects said system against possible accidents.

Abstract: The invention relates to a tower-type system (11) for concentrating and capturing thermosolar energy, comprising a tower (13) having a fixed part (81) and a movable part (82), wherein the movable part ascends or descends along a shaft of the tower (13) and is provided with a gondola (83) that can perform azimuthal rotation, and wherein an assembly of heliostats (12) that can move around the tower (13) direct the solar radiation toward a panel.

Abstract: The invention relates to a cable-based lifting device intended to move loads using multiple cables (1) coupled to an equal number peripheral grooves (2) provided in a single driving pulley (3). The invention comprises: a power unit (6) formed by a motor, a brake, a centrifugal brake and gear reducer, all mounted on a supporting shaft (7); a housing (8) which can be secured to the load to be lifted and in which the aforementioned supporting shaft (7) is housed; a structure (9) which can pivot in relation to the shaft (7) and in relation to the housing (8), said structure containing a pinion coupled to the output of the gear reducer of the power unit (6) and meshed with a toothed wheel (10) that rotates integrally with and concentrically to the driving pulley (3) about the shaft (5); and rollers (11).

Abstract: The invention relates to a cable lifting apparatus for lifting people or loads, including a traction sheave provided with a peripheral groove housing a suspension cable against which rollers apply a pressure in order for the traction sheave to perform the pulling function thereof. The apparatus is designed such that the radial load on the cable is a function of the load to be lifted and of the torque applied by a pinion mounted at the output of the reduction power unit and meshed with a gear wheel integrally connected to, and rotatably concentric with, the traction sheave. The described apparatus allows using a variable number of cables, either by means of the use of a modified sheave provided peripherally with as many grooves as there are cables and having an independent group of pressure rollers for each cable or through the formation of grooves between portions separated by notches made in radial planes between successive portions and having a single group of pressure rollers for all of the cables.

Abstract: The system comprises a cylindrical recirculator (1), with a membrane concentrically fitted therein (6) for defining two chambers, one front chamber (8) and another outer one (9), in such a way that fluid flowing into either chamber causes expansion or constriction of the actual membrane (6) and corresponding impelling of the fluid, all this associated with a set of intake and impeller valves (16?), in combination with intake pumps (33) and impeller pumps (37) and check valves (34) and (35), whereby the fluid is impelled from the intake (31) towards the recirculator (1), so that the fluid flows from the recirculator to a reactor (32) and back again to the recycler (1) for the ejection of the processed fluid through the discharge conduit (36).
