1. A vehicle lift comprising:
a movement system configured to be installed in a pit in the ground,
a platform engaged with the movement system and movable entering to and exiting from the pit,
an arm carried by the platform and configured for lifting a vehicle, said arm being movable with respect to the platform at least between an extended position and a retracted position,
a stop carried by the platform, said stop being movable relative to the platform at least between:
a grip position where the stop engages the arm to block relative movement of said arm with respect to the platform,
a release position where the stop disengages the arm to allow said arm to move between the extended position and the retracted position,
at least one actuator carried by the platform, said actuator being configured for moving the stop between the grip position and the release position, wherein the actuator comprises a hydraulic cylinder or a pneumatic cylinder comprising:
a jacket,
a stem entering and exiting movable with respect to the jacket, said stem being in contact with the rod of the stop,
wherein said stem is movable at least between:
an upper end stop position where a main part of the stem exits from the jacket,
a lower end stop position where a main part of the stem is placed inside the jacket,
wherein the stem, in the lowered position of the platform, is movable between the upper end stop position and the lower end stop position to move the stop from the grip position to the release position.
