Abstract
A turntable includes a floor-level deck and a central support system configured to support the deck for rotation by a central area of the deck. The deck has an underside, a topside and, at its central area, a central relief opening from its underside to its topside. The central support system includes an above-floor stanchion that extends through the deck's central relief, and a topside rotary bearing mounted between the stanchion and the deck to carry the deck for rotation.
Claims20
A turntable, comprising:
- a floor-level deck with an underside, a topside and, at a central area of the deck, a central relief opening from its underside to its topside;
- and
- a central support system configured to support the deck for rotation by its central area, the central support system including an above-floor stanchion that extends through the deck's central relief, and a topside rotary bearing mounted between the stanchion and the deck to carry the deck for rotation.
A turntable, comprising:
- a floor-level deck with an underside and a topside, the deck having a main body formed at least in part from one or more decking elements, and including a topside reinforcement member having a box frame construction spanning a diameter of the deck and connected along the deck's diameter to the one or more decking elements to increase bending resistance across the deck's diameter;
- and
- an above-floor undercarriage configured to support the deck for rotation.
A turntable, comprising:
- a floor-level deck having a main body formed at least in part from a centrally located hub and one or more decking elements connected to the hub, the deck having an underside, a topside and, at the hub, a central relief opening from its underside to its topside, and including a topside reinforcement member having a box frame construction connected along a diameter of the deck to the one or more decking elements;
- a central support system configured to support the deck for rotation by a central area of the deck, the central support system including an above-floor stanchion that extends through the deck's central relief, and a topside slewing bearing that has a stationary inner ring connected to the stanchion, and a rotating outer ring connected to the hub to carry the deck for rotation by the hub;
- and
- a peripheral support system configured to support the deck for rotation by a peripheral area of the deck, the peripheral support system including an underside peripheral guide rail connected to the deck, and one or more above-floor trolleys each including one or more rollers on which the underside peripheral guide rail rides.
