Abstract
A mechanism for transporting a hub is provided. Particularly, a transport mechanism for a pelletizer knife hub is disclosed. The mechanism comprises a clamp for selectively engaging and releasing the shaft of the pelletizer knife hub. The clamp is connected to a support bar. The support bar, in turn, has a hoisting connector for being raised, lowered, and maneuvered by a hoisting system. According to the mechanisms of the present invention, the clamp is rotatable relative to the hoisting system. In one embodiment, a counter-balance to the hub is provided. In another arrangement, the hoisting system supports the hub above the hub for balancing the system.
