ABSTRACT:
The invention relates to a process and device for dynamic measurement of a load in displacement in a vertical plane, this load undergoing a force exerted upward.
The value of the load is determined from its displacement speed in a determined portion of its travel and from a parameter exhibiting a relation with said force in this same travel position. The device comprises a sensor (4) of the hoisting speed of the load in a determined portion of its travel, means (3) for measuring the upward force undergone by the load when it is being hoisted in a determined portion of its travel, and processing means (6) to deduce the value of said load from the displacement speed of the load and of said force.
