Certainly! Here's a refined and expanded version of the original text in English: --- Introduction to Three Types of Equipment for Free Space Operations: 1. **Tripods**: These are essential tools for working at heights, particularly in challenging environments like cliffs and confined spaces. A typical tripod is made from high-strength, lightweight alloy with retractable legs that feature self-locking mechanisms. Equipped with a specially designed stainless steel wire rope, these tripods offer excellent flexibility while ensuring durability against rust and wear. They are ideal for unconventional and non-continuous operations in confined areas such as storage tanks, reactors, railway tank cars, ship compartments, enclosed transport channels, underground pipelines, chimneys, tunnels, silos, pits, vertical shafts, and various liquid reservoirs. Their versatility makes them indispensable in fields like firefighting, municipal services, and emergency response teams. 2. **Mobile Cantilevers**: Unlike traditional tripods, mobile cantilevers provide broader functionality and adaptability. Primarily utilized for free-space rescue missions, fall prevention, lifting operations, and personnel entry/exit through manholes, they operate similarly to tripods but have a larger footprint. This allows them to function effectively in scenarios where tripods might not fit or be practical. For example, they excel in suspension tasks when paired with safety harnesses to prevent falls. Additionally, they serve as anchor points during rescues, facilitate material lifts during emergencies, and support both human and equipment movement within confined spaces. Their wide range of applications makes them invaluable across industries requiring efficient limited-space solutions. 3. **Side Entry Cantilevers**: Also referred to as Side Entry Systems (operating horizontally), these are specifically designed for use on vertical tanks featuring side flange openings. Ideal for lifting, fall prevention, and conducting rescue operations, these systems leverage their horizontal orientation to access otherwise hard-to-reach areas efficiently. Whether it’s moving personnel or materials into or out of restricted zones, side entry cantilevers ensure safe and effective handling of tasks involving limited access points. 4. **Hoisting Boom Cantilevers**: Known as Portable Hoisting Boom Systems (which can operate horizontally or vertically), these units are commonly deployed for rescue operations in confined spaces. To maximize utility, these systems require specific mounting configurations, including designated hoisting points atop the workspace and integration with a winch mechanism. Such setups enhance their ability to lift heavy loads safely and precisely under tight conditions.
