GRAB CRANE Meaning and
Definition
-
A grab crane is a type of heavy-duty machinery designed to lift and move heavy materials or objects with the use of a mechanical grabber or grab bucket. It is commonly used in construction, shipping, and other industries that involve the transportation of bulk materials such as sand, gravel, coal, and various types of ores.
The grab crane typically consists of a large crane superstructure mounted on a stable base, usually on tracks or tires for mobility. It is equipped with a boom that can be raised or lowered to reach the desired location. At the end of the boom, a grabber attachment is fitted, which functions as a mechanical hand that can open and close to grab and release materials.
The grab bucket itself is composed of a series of jaws or claws that can be operated hydraulically or mechanically. These jaws are designed to securely grip and hold onto the material being lifted. The size and shape of the grab bucket can vary depending on the specific application and the type of material to be handled.
When in operation, the grab crane moves into position, lowers the grab bucket to the desired level, and then closes the jaws to securely clasp onto the material. The crane then hoists the load, swings it to the desired location, and finally releases the material by opening the grab bucket.
Overall, the grab crane is a versatile and powerful piece of machinery that plays a crucial role in the efficient handling and transportation of heavy bulk materials.

Etymology of GRAB CRANE
The term "grab crane" is a combination of two separate words with distinct origins:
1. Grab: The word "grab" comes from the Middle English word "graben" which means "to seize or capture". It ultimately derives from the Old English word "græppian". The word "grab" entered the English language around the 14th century.
2. Crane: In this context, "crane" refers to a machine used for lifting and moving heavy objects. The word "crane" originated from the Old English word "cran", which is a shortened form of "cranuc", meaning "a bird of the heron family". The machine was named after the long neck and arm-like structure of the bird, which resembles the mechanical apparatus used for lifting. The term "crane" was first applied to the machine in the late 19th century.
