What are the advantages of a rescue tripod over a quadruped

The rescue tripod is a new type of rescue equipment composed of three light aluminum alloy supports, the top cover at the top and the ring protection chain at the bottom. It is a support frame integrating the two functions of support and rescue. It is mostly used by firefighters in deep well falling rescue accidents, and it is also often used by municipal constructors as a standby tool for lifting and rescue, just because it has many advantages, These advantages are also not possessed by the four corner bracket. Specifically, these advantages are mainly reflected in the following aspects:

1. The fire rescue tripod is easy to carry, because the triangular support has one or even two frames less than the quadrangle support, so it is much lighter in weight and easy for the staff to carry.

2. It is easy to expand. After the operation ground is determined, the staff can directly support the three supports on the ground, while the four corner supports need to be evenly expanded and then supported, and the size is large, which virtually wastes working time.

3. It is convenient to hang the lifting hoist. The three supports of the triangular support jointly lift the top cover, and the top cover undertakes the lifting task. The lifting ring hung under the top cover can be used for the steel wire rope of the manual winch to pass through, and can also be used to hang the lifting hoist for lifting work. The four corner bracket does not have this top cover.

The rescue tripod adopts retractable feet made of high-strength light alloy, with a safety factor greater than 10, and the bottom foot is equipped with a ring-shaped protective chain; The winch is equipped with self-locking devices for lifting and lowering to ensure the safety of the sling; The sling adopts special stainless steel wire rope, which has good flexibility and will not be damaged by corrosion or lack of oil; Convenient assembly, the device can be installed at the wellhead and pit mouth according to local conditions, and is not limited by the uneven ground. The structure is composed of main body, sling, winch and ring protective chain.
