The invention belongs to the field of cranes, particularly relates to a mechanical brake releasing device for a crane, and aims at the problems that an existing mechanical brake releasing device for the crane is relatively complex, high in production cost and not liable to use in use. According to the scheme, the mechanical brake releasing device comprises a first base and a second base, wherein afirst support and a second support are respectively fixedly arranged at the top of the first base and the top of the second base; a positioning rod is fixedly arranged at the top of the first base; afixing rod is fixedly arranged on the top end of the positioning rod; one end of the fixing rod is fixedly connected to the first support; a collision ruler and a sliding rod are slidably connected to the positioning rod; a connecting rod is fixedly arranged on one side of the collision ruler; an upper pulley is rotatably connected to one end of the connecting rod; and a pull rod is rotatably connected to one end of the sliding rod. The mechanical brake releasing device is simple in structure and convenient to use; and furthermore, rapid braking can be carried out on the crane during overloadlifting, so that the crane can be protected, and the mechanical brake releasing device is convenient for people to use.
