Abstract:
An hydraulic force-multiplying actuator is disclosed comprising adjustable pneumatic reaction means (60) adapted to exert a constant reaction pressure and to perform a constant-force stroke, and supplied by compressed-air supplying ducts (52); the actuator further comprises a shoulder (50) for the oil in the working area, and at least one element (11) adapted to prevent the pad of the reaction means (60) from rotating.
Abstract:
The present invention relates to a mixer for concrete and similar mixtures, of the type composed of a parallelepiped tank (2) internally provided with one or more mixing shafts (3), each of them driven into rotation by a corresponding motor unit (UM) in external position with respect to the tank (2), which comprises, with the necessary connections, an electric motor (4), a gear motor (6) and an intermediate gear (7) interfaced with the end of the corresponding mixing shaft (3), characterised by the fact that the electrical motor (4) and the corresponding gear motor (6) of each motor unit (UM) are fixed to a single bearing frame (8) that is hung to the border of the tank (2) by means of one or more hinges (9).
Abstract:
The present invention relates to a mixer for concrete and similar mixtures, of the type composed of a parallelepiped tank (2) internally provided with one or more mixing shafts (3), each of them driven into rotation by a corresponding motor unit (UM) in external position with respect to the tank (2), which comprises, with the necessary connections, an electric motor (4), a gear motor (6) and a cascade of intermediate and reducing gears interfaced with the end of the corresponding mixing shaft (3), characterised by the fact that it is provided with a low-power auxiliary motor (10) connected with the main motor (4), designed to be actuated to drive into very slow rotations the mixing shaft, associated to the main motor (4) during the internal cleaning operations of the tank (2).
Abstract:
The present invention refers to a mixer for concrete, mortar and similar materials, provided with a parallelepiped tank in which two mixing shafts are horizontally mounted in parallel, which rotate inside basically cylindrical chambers, with a longitudinal overturned V-shaped profile in intermediate lower position, whose continuity is interrupted by the presence of a small central rectangular trap, with a hopper fixed in lower external position on the tank and provided with an upper mouth slightly larger than the length of the trap; it being also provided that the trap is equipped with a tilting lid to guarantee closing and opening by means of a suitable actuator.
Abstract:
A modular bed adapted to be composed (1), particularly for truck cabins, is disclosed, composed of a plurality of modular elements (3) adapted to be composed, that are mobile one with respect to another, and that are equipped with respective accessories (5, 7).
Abstract:
An automatic cart for transporting golf clubs or other objects and accessories. The cart has at least one electric drive motor connected to at least one wheel of the cart, at least one electronic controller for controlling the motor, and a plurality of sensors peripherally disposed on the cart. The sensors are used to detect the presence of obstacles in the path of the cart and to sense the signals coming from an external signal source associated with the user. A microcomputer control unit analyses information from the sensors and coordinates movement of the cart so that it stays near the user.
Abstract:
The present invention relates to a support arm (1) for a blade-holding plate (4) used in mixers for concrete, mortar and similar materials, provided with light, inexpensive metal structure obtained with oxygen lance cutting technique and capable of ensuring rapid and fast adjustment of blade-holding plate incidence with respect to the internal vertical walls of the mixer tank.
