Evolution of sub-mechanisms: the last steps of the world’s own crane

Evolution of submechanisms

Among the most famous examples of the massive use of lifting mechanisms in ancient times, the Egyptian pyramids are 2000 years old. All multidimensional blocks have been modified to be suitable for use with properties called shadufs.

Large-scale construction of the Egyptian pyramids

In recent years, the Greeks have been actively captured by “cranes,” which translated into German sounds like “crane.” The remaining number of machines are called “cranes”. With the help of their predecessors, lever lifts, the last temples and palaces were erected to epostes, and in the East, water was moved.

Rotating cranes, reinforced with wooden beams, can be installed, allowing you to lift loads to a height of up to 12 m. At the same time, glue lifts appeared – the “ancestors” of modern elevators.

In this case, a wheel is used in the middle part of the mechanism. This is the final step in separating the skull into water. Armstrom in 1846.

The intense progress in this area was isolated by the steam engine. In 1853 the city of Bath (English) began to be used as the first parsonage.

19th century steam crane

In 1873, the first Koslov crane port was created, in 1875 – a railway crane, in 1887 – the first overhead crane machine.

Types of cranes

Cranes today are one of the most famous classes of special equipment. By design they are divided into majority, gantry, boom, tower, radial, portal and cable.

Depending on the design of the device’s undercarriage, cranes can be rail-mounted, floating, walking, crawler-mounted, automobile, or aircraft.

Overhead crane

They are separated from the skull and by the turret structure – this is the most powerful and the lowest/upper counterweight, with a fixed turret; when building stars with an arrow; in the construction of heavy equipment, casting and foundries; by type of drive – electric, mechanical, hydraulic, combined and by control method.

Overhead crane

The most common types of cranes are overhead, gantry, tower and gantry cranes. Most of the skull bones are used in the above mentioned areas. The lifting mechanism (hoist, winch) moves along a bridge – horizontal guides. Most of the time they are protected by stencils to prevent environmental contamination and work on closed surfaces.

Common Crane

Improving the flow of an overhead crane – gantry crane. Unlike pavement, it has vertical supports and upper parts. These are the most horizontal images. This doesn’t change the mechanism. Gantry cranes move on rails.

Tower crane

Tower crane

It is impossible to imagine a construction site without a tower crane. They are separated from the arrowheads and also mixed with the rails. The lower part represents its platform shape and its vertical position. In the most remote corners of the city there are horizontal stars and engine cabins. The robust crane and platform are difficult to use, as well as the special ial counterweight – kk to the opposite part of the boom. The power is meager, the book is not needed at all.

Portal crane

Portal crane

Cargo is transshipped to the port by powerful gantry cranes. They are also very popular, durable and very cheap. The portals are combined with clocks.

10 identical large cranes in the world

Among our specialists, the ten largest and most beautiful cranes in the world are represented.

1. Liebherr LR13000 crawler crane (Germany, weight 3000 t);
2. Crawler self-propelled jib crane Terex CC8800-1 TWIN (Germany, lifting capacity 3200 t);
3. ALE crane AL.SK190 (UK, weight 4300 t);
4. Under-transport mechanism DLV4000 (China, weight 4400 t);
5. Super crane Sarens SGC-250 (Belgium, weight 5000 tons);
6. Super crane Husenic Biggle 125 AFRD (USA, weight 6803 t);
7. Self-propelled floating crane Svanen (Netherlands, lifting capacity 8700 t);
8. Hyundai 10000 (Junior Korean, total load capacity 10,000 tons);
9. SSCV Thialf (Japan, payload capacity 14200 t);
10. Taisun (China, gross lifting capacity 20,000 t).

Taisun

In April 2009, Yantai Raffles will launch the Taisun crane, which has an incredible lifting capacity of 200,00 tons (this was combined with 420 T-90 tanks). This is, in fact, a stationary gantry (fixed) crane.

Yantai Raffles Shipyard (YRS) was established for Dalian Huarui Heavy Group. Planning for commissioning into 2nd operation lasts 10 months. Taisun specializes in the use of tankers and shallow water platforms.

At the moment, it was possible to display a skull in display cases in 30 minutes. Here is a record of 20,130 tons – the absolute record of the group. Unfortunately, it was not limited to 15 hours.

Technical characteristics of Taisun:

• Design capacity – 20,000 tons;
• Height – 133 m;
• The distance between supports is 120 m;
• Crane lifting height – 80 m;
• The main cable length is 50,000 m.
