The purpose and application of the crane, and what are the main application fields of the loading an

Application of crane: Xinxiang Degong machinery crane is an important tool and equipment to realize the mechanization and automation of the production process in modern industrial production and lifting and transportation. Crane customization is in Xinxiang City, so the crane has been widely used in indoor and outdoor industrial and mining enterprises, iron and steel chemical industry, railway transportation, port terminals and logistics turnover and other departments and places.

The bridge of the crane runs longitudinally along the track laid on the elevated on both sides, and the hoisting trolley runs transversely along the track laid on the bridge to form a rectangular working range, and the space under the bridge can be fully utilized to lift materials, and is not hindered by ground equipment. Xinxiang Degong machinery cranes are widely used in indoor and outdoor warehouses, workshops, wharves and open-air storage yards.

What are the main application fields of loading and unloading cranes, the types of loading and unloading machinery can be divided into bulk material loading and unloading machinery and finished item loading and unloading machinery according to the different materials loaded and unloaded. According to the structural type, it can be divided into two categories: fixed type and running type, and the running type is divided into two types: rail type and trackless type. Chain bucket unloader:

It spans the cargo vehicle and moves on a specially laid track, which is mainly composed of a chain bucket hoist, a belt conveyor, a chain bucket hoisting mechanism, a vehicle running mechanism and a metal frame. The bucket is taken from the open car and the material is lifted and unloaded onto a transverse, bi-directional belt conveyor where it is thrown off the outside of the dumper track. The lifting mechanism of the chain bucket is a set of drum pulley group, which can make the chain bucket hoist lift.

The operating capacity of the chain bucket unloader is generally less than 300 tons. Its disadvantage is that there are often residual materials under the car, and dust flies when unloading. Historical screw unloader:

The working device is a spiral in which two blades rotate in opposite directions. As the spiral rotates, the blades push the material out of the side door of the vehicle. The spiral can be raised and lowered to accommodate the height of the material.

When the operating capacity of the screw unloader can reach 1000 tons, it requires the use of side-opening railway open cars, and the unloading section should have a high roadbed or pit yard. In winter, if the bulk material freezes in the open car, before using the above two types of unloaders, it should be heated and thawed or the frozen block should be crushed. Pneumatic unloader:

A pneumatic conveying device used to unload bulk grain or cement loaded by a boxtruck. The loading and unloading machinery of finished items is used for the loading and unloading of bagged, packaged, bundled, boxed items and timber, metal profiles, machinery and equipment and other finished items. The loading and unloading machinery used in containers and pallets is mainly container carrying bridges, container gantry cranes, straddle trucks, forklifts and pallet trucks.

Application field of loading and unloading machinery portal crane: used for small and medium-sized ports for the loading and unloading of general cargo or bulk cargo, its boom is a single boom type, the whole machine is light in weight, the wheel pressure is small, can reduce the investment in the wharf, and create ideal economic benefits for small and medium-sized ports. As a result, this is a completely new model with a lot of life.

Shipbuilding portal cranes: used for assembly work in shipyards. Its boom is a four-link or single-boom type, the whole machine is light in weight, the wheel pressure is small, and its luffing system adopts wire rope luffing, which can be carried and transfigured, and horizontal displacement.

Rubber tyred crane: It is a kind of full-rotation amplitude non-self-propelled crane powered by three-phase AC power supply, which has the advantages of high limb modification with working efficiency, safety and reliability, simple structure, convenient maintenance, low cost, low energy consumption, low noise, no pollution, etc., it is suitable for ports, factories, mines, docks, etc., and does not need to be used as a frequently moving place for loading and unloading of pieces of goods or bulk cargo. This model is designed and manufactured in accordance with the "GB3811-83 Crane Design Code" and "GB6067-85 Crane Safety Regulations".

Floating crane: marine crane is a hoisting machinery installed on a special hull or hoarding ship of the frame crane, this model can use rack luffing and wire rope luffing (compound pulley compensation) two forms, can be load luffing, and displacement. Hope it helps!

1. Heavy equipment can be divided into several categories according to different structures, such as light and small lifting equipment, lifts, cranes and overhead monorail systems.

2. Light and small lifting equipment mainly includes lifting pulleys, spreaders, jacks, manual hoists, electric hoists and ordinary winch, most of which are small in size, light in weight and easy to use. Except for electric hoists and winches, most of them are driven by manpower, which is suitable for occasions where the work is not heavy. They can be used alone, and some can also be used as a lifting mechanism for cranes.

Some light and small lifting equipment has a large lifting capacity, such as hydraulic jacks, which have a lifting capacity of 750 tons. Lifts are mainly used for vertical or near-vertical lifting movements, with fixed lifting routes, including elevators, lifting platforms, mine hoists and hopper hoists.

3. Cranes. A crane is a multi-action lifting equipment that lifts vertically and handles heavy objects horizontally within a certain range. Overhead type cranes include overhead cranes, special cranes, gantry cranes, loading and unloading bridges, etc.

Boom type cranes include truck cranes, rubber-tyred cranes, crawler cranes, tower cranes, portal cranes, floating cranes, and railway cranes.

4. The elevator is a lifting machinery that lifts heavy objects or fetching devices along the guide rail, and it includes a manned or freight elevator. Although the elevator has only one lifting action, the mechanism is very complex, especially the elevator for carrying people, which requires perfect safety devices and electronic control devices.

Hoisting machinery is a kind of machinery that can complete vertical lifting and horizontal movement of heavy objects at the same time, and is widely used as the main construction machinery in industrial and civil construction projects. There are many kinds of lifting machinery, and mobile cranes are commonly used in construction, including: tower cranes, truck cranes, tire cranes, crawler cranes, etc., as well as the most basic lifting machinery - winches and construction lifts for vertical transportation of high-rise buildings.

The characteristics and scope of application of commonly used cranes are shown below: tower crane 1Pros:

Hello, I have seen your question and am sorting out the answer, please wait for two minutes

Hello, I am happy to answer this question for you, there are many kinds of lifting machinery, which are commonly used in construction for mobile cranes, including: tower cranes, truck cranes, tire cranes, crawler cranes, etc., as well as the most basic lifting machinery - winches and construction lifts for vertical transportation of high-rise buildings.

Some of the working characteristics of lifting equipment are to do intermittent movement, and the crane is customized to Xinxiang Degong Machinery, that is, in a working cycle, the corresponding mechanism of reclaiming, moving, unloading and other actions is alternately working, and the development and use of cranes in the market are becoming more and more extensive.

Due to the lack of outriggers and lifting heavy driving, there are often some accidents, and the speed of Xinxiang Degong machinery crane is also fast; The operation is stable, the lifting capacity is large, and the lifting can be carried within a specific range, but the road must be smooth and solid, the tire pressure meets the requirements, and the lifting from the ground shall not exceed 50cm; It is forbidden to walk long distances with loads.

In order to ensure the safety of the operation, it is basically forbidden to carry out hoisting operations without outriggers in China. The varieties of wire ropes used in Xinxiang Degong Machinery Cranes include phosphate-coated wire ropes, galvanized wire ropes and smooth wire ropes.
