Abstract:
An improved hydraulic lifting sectional security door, capable of being installed at an entry space to a room, comprising a pair of profiles (PRF) near to each frame (STP) of the entry space, a series of panels (PNL) articulated together and a device or group (GP) for lifting the panels (PNL), which includes a hydraulic cylinder (CI), to which fixed and mobile lifting pulleys (PL1, PL2, PL3, PL4) are fixed; according to the invention the lifting cables (FA1, FA2) start from stops (FE1, FE2), which are preferably next to the cylinder (CI) and their exit in the direction of the return pulleys (PU1, PU2) takes place in a balanced manner, on the two outer sides of the lifting pulleys (PL1, PL2, PL3, PL4), so a s to be able to obtain a reversible container (CAS), which allows the hydraulic cylinder (CI) and the exit of the hydraulic tube (TU) to the right or left of the entry space, according to the user's desires and requirements.
Abstract:
An improved vertical-winding high speed door, comprising a construction system that allows it to be produced very quickly and provided with a self-repair system of the shutter in the case of collisions; the door does not need a safety rib either, since it has a construction that is robust, as well as, at the same time, so light as to minimise the mass that can strike a person, who is positioned beneath the door whilst it is closing.
Abstract:
An improved rolling gate (1), is provided with a DC electric motor (25) at a very low voltage, said motor is powered by an accumulator battery (21) associated to a battery charger (20) which can be connected to the 220 V power grid. In this way the gate (1) can be driven independently of the presence of the power grid voltage and the electric system (9) is more economical since it does not require the expensive protective means needed for the corresponding electric systems which work with 380 V current.
Abstract:
An integral formwork system for the construction of pits (20) for loading ramps (10), comprising a set of appropriately reinforced sheet metal panels, piping and sections, bolted to each other; in particular, the formwork is of disposable type, built with specific construction, lightweight, resistant, and compact in size, in order to permit single operation casting for paving (PCL), from the pit level of the formwork without the need to provide special and expensive connecting structures such as flexible joints. Moreover, the system in question also permits the construction of overhang ledges (23) without special moulds; when work is completed, these overhang ledges (23) are able to bear the weight of the loading ramp (10) and the vehicle positioned on it (17).
Abstract:
The improvement consists in providing a motor-driven gate (2) with a 12 Volt DC electric motor (22), said motor being powered by an accumulator battery (18) associated to a battery charger (17) which can be connected to the 220 V power grid. In this way, the gate (2) can always be automatically driven independently of the presence of the power grid voltage. The electric system (6) and the gate (2) according to the present invention, besides being reliable, are more economical and safer with regard to electric shocks.

Abstract:
The improvement consists in providing the drive means (2,2A) of the loading ramp (1) with a DC electric motor (28) at a very low voltage, said motor is powered by an accumulator battery (24) associated to a battery charger (23) which can be connected to the 220 V power grid. In this way the loading ramp (1) can be driven independently of the presence of the power grid voltage and the electric system (9, 9A) is more economical since it does not require the expensive protective means needed for the corresponding electric systems which work with 380 V current.
Abstract:
In order to avoid, automatically, that the rolling gate (1) bumps into someone or something while they pass through the gate opening and to realise said rolling gate (1) in such a way that it has a simple, reliable and inexpensive structure, photoelectric cells (14, 15), which detect the presence of someone or something passing through the gate, are positioned at the ends of the folding arms (6) and they are positioned at a distance, from the lower edge (9) of the rolling gate (1), which is defined in function of the closing speed of the gate (1).
Abstract:
The elevator device (1) is fitted to the rear of the load-bearing structure (14) of a transport vehicle provided with a safety bumper (27). The device (1) comprises a loading platform (2), of which at least two arms (8, 9) operate between the lateral ends (26) of the safety bumper (27) and the point (28) of maximum lateral projection of the vehicle. The device (1) also comprises two elements (5) by which the vehicle load-bearing structure (14) is supported on the ground, these operating as yieldable supports to prevent the vehicle load-bearing structure (14) being able to locally deform permanently when the vehicle attitude changes with changing load.
Abstract:
A high safety hydraulic device for the operation of sectional overhead doors (POR), of the type comprising at least one hydraulic cylinder (CI), connected to at least one hydraulic circuit (MI), which allows the opening or closing of the overhead door (POR), through an electro-hydraulic motor (M), suitable for operating at least one pump for the circulation of a fluid within at least one pipe (TU) of the hydraulic circuit (MI); in particular, between the hydraulic cylinder (CI) and the discharge tank (SC) placed downstream the motor (M), is provided at least one first solenoid valve (VA), normally closed, placed at the outlet of the hydraulic cylinder (CI) and preferably integral with it, and a second solenoid valve (NS), normally closed, placed between the pipe (TU) and the discharge tank (SC).
