Abstract

Mecanismo limitador de la carga de una grúa (1) en una embarcación, donde la grúa (1) comprende un brazo (2) con prolongaciones hidráulicas (3) y una columna de giro (4) unida a la embarcación, con al menos un cilindro de elevación (8) asociado al brazo (2), que comprende un final de carrera (7) que, cuando el brazo (2) de la grúa (1) entra dentro de dos espacios angulares laterales (17) activa un segundo limitador, y un sensor de presión (9) que mide la presión que soporta el al menos un cilindro de elevación (8), tal que con el final de carrera (7) activando el segundo limitador y el sensor de presión (9) midiendo una presión superior a un umbral, el brazo (2) tiene limitado su movimiento a recoger las prolongaciones hidráulicas (3).Mechanism limiting the load of a crane (1) on a vessel, where the crane (1) comprises an arm (2) with hydraulic extensions (3) and a turning column (4) attached to the vessel, with at least one lifting cylinder (8) associated with the arm (2), which comprises a limit switch (7) which, when the arm (2) of the crane (1) enters two lateral angular spaces (17) activates a second limiter , and a pressure sensor (9) that measures the pressure that supports the at least one lifting cylinder (8), such that with the limit switch (7) activating the second limiter and the pressure sensor (9) measuring a pressure above a threshold, the arm (2) has limited movement to collect the hydraulic extensions (3).
