Mounts to horizontal concrete or steel structures providing anchor point base for offset davit mast. Attaches to horizontal surfaces where frequent confined space system set-up is required providing a permanently installed davit mast base to an existing structure. Stainless steel offers maximum corrosion resistance to stand-up to the harshest environments, providing added longevity. Offers a compatible anchor point for all Advanced™ davit masts and is perfectly matched to handle the variable capacities. Designed to allow installed davit mast to rotate freely for maximum flexibility and freedom of movement. PVC davit mast sleeve liner eliminates metal to metal contact improving performance and ensuring smooth consistent davit mast rotation. Install with tools found in most facilities reducing time and cost of set-up. Provides great corrosion resistance and durability in harsh environments for extended longevity. The Advanced™ series hoist system bases are designed for manhole and confined space entry/retrieval applications. Portable units are constructed of lightweight high-strength aluminum and adjust to fit most standard entries.
