Level Luffing Crane
A level-luffing crane is a crane mechanism where the hook remains at the same level while luffing: moving the jib up and down, so as to move the hook inwards and outwards relative to the base. Usually the description is only applied to those with a luffing jib that have some ''additional'' mechanism applied to keep the hook level when luffing. Level-luffing is most important when careful movement of a load near ground level is required, such as in construction or shipbuilding. This partially explains the popularity of fixed horizontal jibs in these fields. Toplis cable luffing An early form of level-luffing gear was the "Toplis" design, invented by a Stothert & Pitt engineer in 1914. The crane jibs luffs as for a conventional crane, with the end of the jib rising and falling. The crane's hook is kept level by automatically paying out enough extra cable to compensate for this. This is also a purely mechanical linkage, arranged by the reeving of the hoist cables to the jib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Crane (machine)
A crane is a machine used to move materials both vertically and horizontally, utilizing a system of a boom, hoist, wire ropes or chains, and sheaves for lifting and relocating heavy objects within the swing of its boom. The device uses one or more simple machines, such as the lever and pulley, to create mechanical advantage to do its work. Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment. The first known crane machine was the shaduf, a water-lifting device that was invented in ancient Mesopotamia (modern Iraq) and then appeared in ancient Egyptian technology. Construction cranes later appeared in ancient Greece, where they were powered by men or animals (such as donkeys), and used for the construction of buildings. Larger cranes were later developed in the Roman Empire, employing the use of human treadwheels, permitting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Jib (crane)
A jib or jib arm is the horizontal or near-horizontal beam used in many types of crane to support the load clear of the main support. An archaic spelling is gib. Usually jib arms are attached to a vertical mast or tower or sometimes to an inclined boom. In other jib-less designs such as derricks, the load is hung directly from a boom which is often anomalously called a jib.

Stothert & Pitt
Stothert & Pitt was a British engineering company founded in 1855 in Bath, Somerset, Bath, England. It was the builder of various engineering products ranging from Crane (machine), Dock cranes to construction plant and household cast iron items. It went out of business in 1989. The name and intellectual property became part of Clarke Chapman. History George Stothert (n.b. early on the name is sometimes rendered as Stoddard or Stodhert) moved to Bath in 1785 having taken over Thomas Harris's ironmonger's business. He was an agent for Abraham Darby I's Coalbrookdale, Coalbrookdale Iron Company, selling all types of domestic ironmongery.

Meccano
Meccano is a brand of construction set created in 1898 by Frank Hornby in Liverpool, England. The system consists of reusable metal strips, plates, angle girders, wheels, axles and gears, and plastic parts that are connected using nuts and bolts. It enables the building of working models and mechanical devices. In 1913, a very similar construction set was introduced in the United States under the brand name Erector. In 1990, Meccano bought the Erector brand and unified its presence on all continents. In 2013, the Meccano brand was acquired by the Canadian toy company Spin Master. Meccano maintained a manufacturing facility in Calais, France until 2023. History First sets An early Meccano set on display in the Museum of Childhood (Edinburgh), Edinburgh Museum of Childhood In 1901 Frank Hornby, a clerk from Liverpool, England, invented and patented a new toy called "Mechanics Made Easy" that was based on the principles of mechanical engineering.
