Abstract: A mining elevator carrying platform and carrying method, the platform comprises a power system (1) and a four-rod carrying device (5), a rotating rod (3) connected with the power system (1) is set on the carrying device (5); the power system (1) comprises a flameproof motor (1-1), a upper-limited switch (1-2), a down-limited switch (1-5) and a main pulley (1-6), the flameproof motor (1-1) is connected with the main pulley (1-6) through a main steel cable (1-4), a baffle (1-3) is set on the main steel cable (1-4), a double cable channel is set on the main pulley (1-6), and the main pulley (1-6) is connected with a sub-pulley (1-8) by a sub-steel cable (1-7), a sliding plate (1-9) is set on the sub-steel cable (1-7), and a sliding rod (1-10) is set on the sliding plate (1-9). The main pulley (1-6) is driven to rotate by the flameproof motor (1-1) through the main steel cable (1-4), thus the sub-pulley (1-8) is driven to rotate.

Abstract: Carrier car door assemblies respectively comprising a carrier car comprising a body, a door, a drive mechanism, a driven mechanism, and a magnetic release mechanism are disclosed herein. The carrier car travels along a track system between teller and customer stations to transport materials there-between. The door is connected to the body and movable between a door-closed position and a door-open position. The drive mechanism is connected to the body and to the driven mechanism so that the drive and driven mechanisms synchronously move between respective door-closed positions and door-open positions. The magnetic release mechanism is connected to the driven mechanism and moves from a magnetically coupled state to a magnetically de-coupled state when a user manually moves the door from the door-open position to the door-closed position. The magnetic release mechanism in the magnetically coupled state synchronously moves with the driven mechanism between door-closed and door-open positions.

Abstract: In an underground storage space, particularly for endangered goods, access is effected via a left the opening of which, leading into the storage space, can be closed by two covers which are arranged spaced apart from each other.

Abstract: Waste collection device that includes a pit provided with a lid that has waste insertion pillars and with a lifting unit that is suitable to move at least one waste container; the device is characterized in that the monolithic lid is pivoted to the edge of the pit and is kinematically connected to the lifting unit so as to perform the opening and closing motions respectively during the ascending and descending movements of the lifting unit.

Abstract: An elevator drive, which moves an arcuate car door attaching to a support that rotates about an axis, has a motor having an output, an arm attached to the output, and a linkage having a first coupling allowing compound motion attached to the arm and a second coupling allowing compound motion attached to the support, the door moving as the arm rotates in response to motion of the output.
