A jack includes a main body (14) with a cavity (18). A lifting cylinder (42) is supported on the main body and is extendable into the cavity. A lock (30, 34) is movably coupled to the main body. A spring (38) is coupled to the lock and biases the lock into the cavity. A cylinder (86) is coupled to the lock and biases the lock out of the cavity against the biasing force of the spring.

    Un vérin comprend un corps principal (14) ayant une cavité (18). Un cylindre de levage (42) est supporté sur le corps principal et peut s'étendre dans la cavité. Un verrou (30, 34) est accouplé de façon mobile au corps principal. Un ressort (38) est accouplé au verrou et sollicite le verrou dans la cavité. Un cylindre (42) est accouplé au verrou et sollicite le verrou hors de la cavité contre la force de sollicitation du ressort.
