Abstract (en)
A drive (1) for goods hoists and elevators (2), of the type that comprises a compartment within which a car (3) and a counterweight (4) are guided so that they can slide in a parallel arrangement in opposite directions, comprising a motor drive (5). The motor drive (5) comprises a pinion (6) that is provided with a suitable set of teeth (8), whose diameter does not exceed 65 mm, and is functionally associated with a respective toothed belt (7). The reduced diameter of the pinion (6) determines the need for a low driving and/or braking torque with respect to the performance of the system in which it works, and therefore a reduction in the mass and moment of inertia of the motor drive (5).
