The term "low net empty handed gourd" might be a specific reference in a niche context, but generally, when discussing materials related to hoists or similar lifting devices that could be colloquially referred to with such terms, the focus is on the structural and functional components. However, if we interpret this as inquiring about materials relevant to a hoist system (given the context of corrosion prevention methods previously discussed for a hand chain hoist), the main materials would typically include:

Metals for Structural Components:

Commonly used metals include stainless steel, galvanized steel, or other alloys known for their strength and corrosion resistance. These metals form the frame, hooks, chains, and other load-bearing parts of the hoist.

Protective Coatings:

To enhance corrosion resistance, materials such as paints, varnishes, or powder coatings are applied to the metal surfaces. These coatings act as barriers against moisture and corrosive agents.

Lubricants:

Lubricating materials, such as oils or greases, are used to reduce friction and wear between moving parts. They also help to displace moisture and prevent corrosion in the internal mechanisms of the hoist.

Ropes and Cables:

If the hoist includes a rope or cable system for lifting, these are typically made from high-strength synthetic fibers or steel wires, chosen for their durability and load-bearing capacity.

Fasteners and Connectors:

Bolts, nuts, screws, and other fasteners are used to assemble the hoist. These are usually made from corrosion-resistant metals to ensure the integrity of the connections over time.
