The use of twine and rope for everyday activities of humankind, aged in ancient times, maybe prehistoric, when the early humans to perform fastening, joining, pulling, carrying and lifting objects (in the style of today’s lifts) They used something like a rope. It is possible that the use of humans used to be something like “ropes” naturally and from plant fiber, such as grapevine, palm fiber, and the like, during an exploration that led to the founding of a fossil of A piece of the “Probably two-Ply ground rope of about 7mm diameter” rolled into one of the “Lascaux” coils, after examining the experts on the fossa Yale showed that:
“The existence of the rope is estimated to be around 15,000 BC.” The ancient Egyptians were probably one of the first civilizations that succeeded in making ropes of papyrus, palm shells, flax, straw, leather, and skin and animal hair in various ways, producing ropes for about 3,500-4,000 years before In the Middle Ages (between the 13th and 18th centuries), the Ropewalks were used, except for everyday life, in mines, and in sailing and building (in a hoist mode).
Italian designer Leonardo da Vinci, designer Leonardo da Vinci Leonardo da Vinci, designed a cord fabric design that, like many designs and inventions, never produced.
In 1586, Domenica Fontana succeeded in using thick, hand-made, pyramidal stone pillars made of red granite with a weight of 327,000 kg, with a height of 25.5 meters, with the help of force A total of 900 people, along with 150 horses and 47 self-propelled elevators, were located in the middle of the Rome’s Sainpeter’s Square, at that time moving, lifting and holding the stone was remarkable for this magnificence. Is.
The 25.5-meter stone is installed in the middle of the field.
(In the case of this stone it is said that this red granite stone dates from the 13th century BC, which was transmitted to Rome in the first century AD) and installed it at the time of St. Peter’s Square in Rome The rule of the Siwtus V was done ..
• When did cotton yarn ropes turn into wire ropes?
ParsLift site has been working hard to collect pristine and first-hand information and has been working with extensive and continuous research, in this field, although small, to the large family of elevator industry and industry enthusiasts and all the scientific information seekers. It is surely possible to narrow down and slip in this path, therefore, all the loved ones who are reminded of these shortcomings with magnificence are grateful.
The first towed wire was invented by Wilhelm August Julius Albert, Wilhelm August Julius Albert. “Albert is known as the inventor of wire rope.”
He was born on January 24, 1787 in Hanover, Germany, and died on July 4, 1846 in Clausthal.
In 1831-1834, Wilhelm August, Julius Albert, a mining engineer, was managing the Clausthal Caroline Mine in the Harz Mountains.
Considering that in this mine the conveyor chains and the ropes of vegetable fibers with pulleys and elevators were used, the moisture content of the mine and the friction of the rope with stone walls and their stretching caused a very short life due to their failure, Albert in this The idea was to think for this problem, and so in the years 1832 to 1833, using the ancient spinning technique, manually weld metal wire strands into triangles to form a string, then three or four Use these strings around a core using a string of wires
Fabrication of a combination of natural textile fibers: Manila, Sisal, Henequen
(Fibers used for weaving or hemp) made the wire to be soft and flexible, and largely prevented fatigue and fracture of the wire bead layers. This item is one of the great features and creations of John Augusto Roebling. Although the metal rope was very rigid and relatively bulky, it had a high resistance and durability.
Wire wire production was very difficult at that time, because it was necessary to hit an iron mass after heat by using the hammer and the anvil, so that the mass was turned into bars, then the thick wire and with repetition Hammer make it slimmer and thinner.
Then the welded joints are welded together to form a long wire line.
For the first time, the Wilhelm August Molly Albert Handlebar (for lift) was used for 384 meters in July 1834 for use in the Clausthal Caroline mine in the Harz Mountains.
The lift wire to which it was used had a diameter of about 17 mm in diameter, made up of three wires of steel wires with an internal diameter of about 3.5 mm, and these three strands formed the core of the main tower .
In those years, Albert’s invention of wire rods became known as “Albert Ropes” long after its invention.
ROBERT STIRLING NAWAL INVENTOR SWIVEL WIRE SWIVEL MACHINE
Meanwhile, another Andrew Smith, Andrew Smith, using various methods on Albert’s wire rope and using the Ropewalk technique tried to reduce its stiffness and stiffness to some extent, and to use it more appropriately. Make
ONE OF THE EARLIEST WIRE BENDING MACHINES
In 1838, Robert Stirling Newall, who was studying at the mine, Robert Stirling Newwald, English (born May 27, 1812 in Dundee, Scotland), visited a silver mine, closely connected with Albert and the cable tray of the invention. He got acquainted.
Using a series of pulleys and gears that were massively interlocked with the Albert winding simulator, he attempted, with the general rotation of the wires from the pulleys, to open and at the point The focal length was combined with the collision and was tangled through the continuous rotation to the opposite end, where it was removed by a more compact system of integrated wires. Eventually, in 1840, with the completion and design of the “wire towing machine”, he succeeded in automatically tightening the wire rope.
