Different models of cranes

Different models of crane
 1,  Large scale application of truss type Longmen crane in bridge industry
 We also call trussed gantry cranes for highway bridge and portal cranes, road  bridge doors cranes, road bridge cranes, bridge cranes, etc. Why can the double beam truss Longmen crane be widely used in the highway and bridge industry? What are the characteristics of the truss crane?

Road and bridge project girder factory, material field, suspension bridge is the main site of double girder bridge portal crane. The bridge type Longmen crane can be divided into single hook door machine and double hook door machine, also known as single door Longmen crane and double door Longmen crane. The two structures of the leg (angle steel, square steel  assembly) and round tube and leg are the main structures of the leg of Longmen crane. The lifting weight has no fixed value, which can be changed at any time

According to the requirements of the factory. Double beam truss Longmen crane operates in two ways: bridge operation and improved remote control. The main girder of the truss crane is simple in structure, and the metal structure of the overhead  traveling crane is connected by pin or flange.
Main structure of truss gantry crane
The main structure of the truss type gantry crane is nine parts of the main structure of the truss type gantry crane: big car walking, leg, main beam, lifting trolley, stabilizer bar, balance beam, operation room and the base of the operation room.

Advantages of truss gantry crane
It is easy to transport, install and disassemble, the work place is not high, the speed stability is the advantage of the truss gantry crane, its hoisting bridge needs two gate machines, and the double beam truss Longmen crane hoisting bridge can be independent but the span requirement is larger. Because of wind resistance, the portal crane with large sand frame structure is not easy to collapse. This is why the double beam truss Longmen crane can be used in large-scale application of road and bridge industry.
2,  Tong Crane for Sale: Crane with Lifting Tongs
The cranes can be used to hoist different materials by installing different tongs. Trailer cranes, cranes, wooden tongs, log tongs, industrial tongs, metal tongs, rail tongs, ingot tongs, clippers, tongs, and trolley tongs, these are all kinds of tongs.

The operation forms are ground operation, remote control, cab operation structure, box girder double main girder.
The product principle diagram and technical specification of the general type crane 

A summary of the product structure of the clamp crane 

The bridge crane consists mainly of three parts
Tung bridge crane across the runway
The hoisting trolley crosses the bridge and bumps up and down.
A runway connected to a building structure.
The crane pliers are parallel to the main beam.
Steel plant, shipyard, port, yard, warehouse and other indoor and outdoor intersections are the operating places of the general type bridge type crane, the main responsibilities are loading and unloading, loading and unloading materials such as slab, profile and so on.
The clamp crane is especially suitable for lifting the steel billet of different  specifications. It can be equipped with different lifting tongs according to the specifications of the hoisting material (thickness, length, plate quantity, etc.) so as to meet the requirements and weight of the lifting operation.
Meet customer requirements, speed regulation (above 1:10), overload alarm, remote  control, PLC control and fault detection, display system and so on.
A double mechanism 4 brake structure hoist is adopted to ensure that the motor  belt overspeed switch is lifted smoothly and safely.
The main electrical control elements are arranged in the main girder, which can  prolong the service life of the electrical components and reduce the electrical control failures.
The double hanging crane clamp device can be operated by self locking clamping  device, switch positioning and automatic tinctle opening and closing. It not only does not consume electric energy, but also is beneficial to environmental  protection. Its advantages are simple structure, convenient manufacture, low price, small appearance and light weight.
Slab Tong Crane Application 

Lifting Tongs Application
Bale tong, Billet tongs, Box tong, Crate tong, Cylinder tong, Die lifting tong, Gear tong, Ice tong, Ingot tongs, Mill roll tong, Paper roll tong, Pipe tong, Slab tong, Tube tong
We provide you not only tong crane but also overhead crane,gantry crane, jib crane,electric hoist and electric winch, if you  need, please feel free to contact us.

 3.  Cantilever crane

1).  Type selection of cantilever crane
Low requirements for mechanical mobility, stability and ground pressure; use of a truss arm (mechanical drive) or a cantilever hanger with a telescopic boom (hydraulic transmission); is a professional cantilever beam used? Cantilever crane selection should consider the following three questions.
When there is a large weight in the hoisting project, it should be installed with high height and large change of operation. According to the existing mechanical conditions, it is a good solution to use a caterpillar or fixed cantilever crane.
The crawler cantilever is most suitable for the soft working environment with poor driving conditions, and the tire type cantilever suspension is suitable for the environment which is not allowed to damage in the working area.
2).Model selection of cantilever crane
According to the lifting capacity and height, the appropriate specifications can be found in the sample or technical performance of a moving cantilever crane, while other conditions in the field are taken into account. Due to the maximum lifting weight of the crane, it is difficult to give full play to the difficulty of all kinds of performance in the hoisting project, and the use rate is low. So, as long as the technical requirements are met, there is no need to choose a large model crane.
3).The choice of the economic performance of a cantilever crane
The application of cantilever crane in stone processing industry

Cantilever crane and column cantilever crane are used in stone processing industry to install and hoist stones.

 Cantilevered cranes solve problems arising from stone processing plants 

Stone is heavy and heavy, and it also meets the needs of fast peers. This kind of work makes the failure workers of private enterprises lose quickly. With the passage of time, industrial glue is widely used in stations, and the pollution of working environment and human body will become more and more serious. Ultimately, people's transport safety is very dangerous and efficiency is reduced.
The reason for choosing a cantilever crane
The cantilever crane adopts the ground installation, directly existing bolts on the ground, and does not need to add special foundation. So the 360 degree rotation hoisting operation is realized, the position of the artificial forklift is liberated effectively, and the production cost is greatly reduced.
A slewing pin on the shaft of a cantilever crane can effectively prevent the boom from rising unexpectedly. At the same time, the rotating shaft bearing makes the rotation extremely convenient, effectively improves the on-site processing and counterpoint efficiency, reduces the accidents and reduces the labor cost.
According to your workshop conditions, we can provide you with customized cantilever cranes. Under your request, we will provide you with satisfactory crane design.
4. Bridge cranes
Bridge cranes can be used to maintain rail transit vehicles.
Double beam crane is used to lift heavy load machinery, such as the normal operation of urban rail transit vehicles and urban rail transit or the maintenance and  maintenance of urban rail traffic vehicles.

 East elevated overhead cranes can be used for rail, high-speed trains, subway vehicles, and freight vehicles. The new double girder bridge crane designed according to the European standard has the following characteristics: 

Full frequency control, smooth lifting operation, small impact;
Anti swing crane technology which can effectively reduce load swing.
The structural parts that ensure the installation precision are processed as a  whole.
The appearance is beautiful, the weight is light, and the noise is low.
If you want to improve heavy materials, you can choose ramhoist double girder overhead crane. The selection principle of comprehensive economic performance standard is to make materials or parts in the process of transportation, hoisting and handling. The wall hanging cantilever crane is the lowest unit  price in all cranes, so that the workload (or contract production capacity) is used to calculate the unit price of material transportation, and the consumption is the least. In addition, less energy consumption should also be considered in the direction of reducing labor intensity of products.
