The Four Piece Hoist System is designed for manhole and confined space entry/retrieval applications. The modular design allows use of components in various configurations and applications. Multiple winches and/or lifeline systems may be mounted as required. Tool-less design breaks the system into lightweight, manageable components for storage, transport, and setup. The DH-2 features the DH-3 Mast, and DH-4 Base to further increase adjustability and setup options.
