Conceptual analysis: Hand Crunked Gourd

Definition and Classification

Hand cranked haws are a composite concept that combines practical functionality and cultural symbolism. According to their application scenarios, they can be divided into two categories:

Mechanical tools: refers to manual lifting equipment that lifts heavy objects by manually turning the crank or pulling the bracelet, such as chain hoists and hand cranked hoists. Its core structure includes a differential pulley system, a gear transmission system, and an impact resistant gearbox, which can achieve efficient lifting by amplifying manpower (such as manual pulling force that can be increased by thousands of times). It is suitable for non power environments (such as mines, construction sites, docks) or portable scenarios.

Cultural handicrafts: Hand cranked musical instruments or cultural ornaments made from gourds. For example, the "Hand Carved Gourd Shaker" in Peru produces a sound effect similar to rain when shaken by carving the gourd shell and embedding beads, which is used in traditional music or rituals; Cultural gourds are made through techniques such as molding, carving, and painting, and have both playable, collectible, and cultural symbolic value.

Structure and Function

Mechanical tools:

Hand pulled hoist: composed of a chain, gears, handwheel cover, and load-bearing chain, using an aluminum integrated frame, it has the characteristics of impact resistance, lightweight and easy to carry. Its working principle is the "differential pulley system", which drives the internal gears to rotate by pulling the bracelet, achieving the lifting of heavy objects. Typical specifications range from 0.25 tons to 30 tons, with some customized models capable of larger lifting capacities.

Hand cranked hoist: By pulling the handle to drive a conical rotor motor or electromagnetic brake, it can achieve traction and lifting of steel wire ropes or ring chains. It is suitable for narrow spaces or inclined operations, with a rated lifting capacity ranging from 250 kilograms to 9 tons.

Cultural handicrafts:

Musical instruments such as the Peruvian "Rain Stick", which involves carving gourd shells and filling them with beads to create a continuous rain sound effect when shaken. It is commonly used in meditation, healing, or traditional rituals.

Cultural gourd: made through molding (shaping the shape of the gourd with molds), carving (engraving historical stories, myths and legends), or pyrography (drawing patterns with high-temperature soldering iron) techniques. The height of high-quality cultural and artistic gourds is usually 3-5 centimeters, with delicate leather and a yellow white color that becomes smooth and shiny over time. It also has the functions of massaging acupoints and fitness and health preservation.

Historical and Cultural Background

Practical origin: Gourd, as a plant fruit, was first used for carrying water, storing wine, or making household utensils, such as the record in the Book of Songs that "melons are eaten in July and pots are broken in August". Its wooden shell makes it an ideal container material.

Cultural symbolism: The gourd sounds like "Fu Lu" in Chinese, while the branch and stem sounds like "Wan Dai" in Chinese, symbolizing "double prosperity and prosperity, and ten thousand generations of descendants". In Taoist culture, gourds are regarded as sacred objects, such as the gourd with iron crutches symbolizing a fairyland; In folk customs, gourds are used for praying for blessings and warding off evil spirits, such as hanging at the front of a door or under a roof beam, symbolizing peace.

Technological development: During the Ming and Qing dynasties, the carving and molding techniques of gourds reached their peak. For example, in the Qing dynasty, the palace molded gourds were shaped using wooden or tile molds and solidified with gypsum or mud to form exquisite patterns. Literati and literati such as Li Wenzhai incorporated calligraphy, painting, poetry, and literature into gourd carving, creating historical story themes such as "Wang Xizhi Loves Geese" and "Seven Sages of the Bamboo Grove", making gourds a representative of the elegant hall of handicrafts.

Modern application: Hand cranked hoists in the industrial field are improved in efficiency and safety through technological advancements such as dual speed frequency converters and high alloy steel chains; In the cultural field, innovative designs such as geometric patterns and natural themes are used to attract young people and become a carrier for the integration of traditional craftsmanship and modern life.

Application scenarios

Industry and Construction: Hand pulled hoists and lever hoists are used for equipment installation, cargo lifting, object fixation, and traction operations, especially in outdoor, non powered, or narrow spaces where they have significant advantages.

Culture and Collection: Cultural gourds serve as objects of play, combining functions of fitness, collection, and cultural inheritance; Gourd instruments are used for traditional music performances, rituals, or artistic creations.

Folk customs and daily life: Gourds are used as mascots in weddings, praying for blessings, warding off evil, and other scenes. For example, the "Heji" ceremony symbolizes the union of husband and wife, or hanging them at home symbolizes peace.
