Lifting machinery refers to the mechanical and electrical equipment used for vertical lifting or vertical lifting and horizontal movement of heavy objects, and its scope is specified as a lift with a rated lifting capacity greater than or equal to; Cranes with a rated lifting capacity greater than or equal to 3t (or tower cranes with a rated lifting moment greater than or equal to 40t·m, or loading and unloading bridges with a productivity greater than or equal to 300t h) and a lifting height greater than or equal to 2m; Mechanical parking equipment with more than or equal to 2 floors.
2. According to the "Catalogue of Special Equipment" promulgated by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, lifting machinery is divided into: bridge cranes, gantry cranes, tower cranes, mobile cranes, portal cranes, lifts, cable cranes, mast cranes, and mechanical parking equipment.
3. Lifting machinery can also be called lifting equipment.
4. Crane refers to a multi-action lifting machinery that lifts vertically and carries heavy objects horizontally within a certain range. It is also known as overhead crane, aerial crane, crane.
5. Lifting machinery, according to its different structure and performance, can generally be divided into four categories: light chiming small lifting equipment, bridge type lifting machinery, boom type crane, and cable crane. Light and small lifting equipment such as: jacks, pneumatic hoists, electric hoists, balance hoists (also known as balance cranes), winches, etc.
Bridge type lifting machinery, such as beam cranes, etc. Boom type cranes such as fixed slewing cranes, tower cranes, truck cranes, tire cranes, crawler cranes, etc. Cable cranes such as lifts, etc.
6. According to the nature of lifting: mobile cranes, tower cranes, and mast cranes.
7. According to the driving mode, it is divided into: one is centralized drive, that is, a motor is used to drive the long drive shaft to drive the active wheels on both sides; The other type is separately driven, that is, the active wheels on both sides are driven by an electric motor. Medium and small overhead cranes mostly use brakes, reducers and motors to integrate the "three-in-one" drive mode, large lifting capacity of ordinary overhead cranes in order to facilitate installation and adjustment, the drive device often uses universal coupling embedding.
8. According to the structural form, the crane is mainly divided into light and small lifting equipment, bridge type (bridge type, gantry crane), boom type (self-propelled, tower type, portal type, railway type, floating ship type, mast crane), cable type.
9. The main parameters of the crane are the parameters that characterize the main technical performance indicators of the crane, the basis for the design of the crane, and the important basis for the safety technical requirements of the heavy machine. It can be divided into rated lifting capacity, maximum lifting capacity, total lifting capacity, effective lifting capacity, etc.

Anonymous users2024-02-06European single girder crane, with light weight, small structure and low energy consumption. The European-style crane adopts a unique design concept, which has the characteristics of small size, light weight and small wheel pressure. Compared with the traditional crane, the limit distance from the hook to the wall is the smallest, the headroom is the lowest, it can be closer to the front operation, and the lifting height is higher, which actually increases the effective working space of the existing plant.
The European-style single girder crane realizes the stepless speed regulation of frequency conversion between 0-45m min, and adopts a low headroom design, which can effectively increase the dispatch space, as well as the unique C-shaped structure, which correspondingly improves the dispatch space.
The European-style single girder crane starts and runs smoothly, without impact, and has a good silent effect, which can reduce the harm of noise.
The European-style single girder crane has a low failure rate, which reduces the maintenance cost to a large extent, and the service life is up to 30 years without worries.
The European-style optimized design not only has a light weight, but also can be programmed to lift and limit the position to achieve comprehensive protection, and the protection level is IP55 and H class insulation, which has a strong effect.
In the composition of the system, there is a hard tooth surface reducer, high bearing capacity, long life, electric disk brake, dustproof, self-debugging brake, no manual adjustment, semi-grease lubrication and high-strength galvanized anti-rust steel wire rope, maintenance-free, and there is a motor, brake, reducer three-in-one drive.
The European-style single girder crane can be applied to warehouse loading and unloading, material handling, mold assembly and other work scopes.
The main beam of the European-style single girder crane is mostly made of I-shaped steel or a combination of steel type and steel plate, and the lifting trolley is often assembled by chain hoist, electric hoist or hoist as a lifting mechanism component, which is used to lift goods on different occasions.
The European-style single girder crane adopts hardware configurations such as high-strength galvanized steel wire rope, disc brake, hard tooth surface reducer, programmable lifting limit, anti-cable-stayed rope guide, and is equipped with real-time monitoring, electronic anti-sway, inch function, micro-speed function, zero-speed hovering, 4G remote communication, remote diagnosis, automatic control and other intelligent modular functions, so as to easily realize intelligent handling.

Public relations companies, also known as public relations companies, are composed of professional public relations experts and various public relations professionals, and are informational, intellectual, communication and organizational service agencies that specialize in providing public relations consulting for social organizations or accepting and entrusting clients to carry out public relations activities.
Amway China is not the same as Amway America.
Wheat regions --- distributed in the central and northern parts of the Great Plains. Spring wheat in the north and winter wheat in the middle, depending on the climate. The natural reason for the development is the flat terrain, fertile soil, rain and heat at the same time, and abundant water sources. >>>More
Although Taoism is China's native religion, why don't people mention it now? The main reason is that the original Taoism has no essential elements of Taoism, but instead molds Taoism into a ghost and deification. To put it bluntly, Taoism is evil.
