The word "jib crane" is spelled with a /dʒ/ sound at the beginning, followed by a long /i/ sound in the vowel, and then a /b/ sound and an ending /kreɪn/. The letter "j" is pronounced as the affricate /dʒ/, while the letter "i" has the long vowel sound /aɪ/. The word "jib" comes from the nautical term for a triangular sail, which this type of crane's arm resembles. It is used to lift heavy loads in construction and manufacturing industries.
A jib crane is a type of crane that utilizes a horizontal arm, known as a jib, to lift and move heavy loads. It consists of a vertical mast or pillar that provides support and stability, along with a movable horizontal boom or jib that extends outward at a right angle from the mast. The jib crane is designed to be mounted or attached to a wall, floor, or other stable structure.
The jib crane operates through a manual or motorized system that allows the boom to rotate horizontally, allowing for easy maneuverability and precise lifting. It often incorporates a hoist or lifting mechanism that is attached to the jib, providing the power to raise or lower the load.
Jib cranes are commonly used in industrial settings, warehouses, and construction sites due to their compact design and versatility. They are particularly ideal for tasks that require precise positioning and control, as well as handling loads in confined spaces. The range of motion provided by the jib allows for lifting and rotation in a specific radius, effectively extending the reach and capabilities of the crane.
Overall, a jib crane is a specialized lifting device that utilizes a horizontal jib to facilitate the movement of heavy loads in a controlled and efficient manner, providing stability and enhancing productivity in various industrial and construction applications.
The word "jib" in "jib crane" comes from the Middle French term "giber", which means "to handle roughly" or "to shake". This word later evolved into the Old English word "gybban" or "gibben", which means "to fasten". Over time, "gibben" transformed into "jib", referring to the projecting arm or boom of a crane that can be moved or adjusted. The term "crane" in this context comes from the resemblance of the structure of the jib arm to the long-necked bird's beak and neck. Therefore, the term "jib crane" describes a type of crane with a projecting arm or jib that can be maneuvered to lift and move objects.
