ballast device for optimization of conditions for static balance and dynamic of cofferdams, push

摘要

the subject of the patent claim is a device of ballast offset for optimization of conditions of static balance and dynamic of cofferdams to push water subjectto condition variables and wave motion.the device in question, explained in the technical description and the box graphs annexes, is a ballast for selective intervention.in the sense that only take action for inclination angles of the lift that up above the inclination of exercise or only in the field of positions in which the lift that up to problemi instability of balanceachieving functional characteristics of stability of the sluices is significantly superior to those obtainable with elements of ordinary ballast to surgery is not selective.
