Uncategorized

The working strength of the cantilever crane is light. The crane consists of a column, a rotary arm rotary drive device and an electric hoist. The lower end of the column is fixed on the concrete foundation by anchor bolts. The cycloidal pinion reduction device drives the cantilever rotation. The electric hoist is in the cantilever. The word steel runs on the left and right lines and lifts heavy objects. The swing arm of the crane is a hollow steel structure with light weight, large span, large lifting capacity and economical and durable. The built-in walking mechanism adopts special engineering plastic walking wheel with rolling bearing, which has small friction and light walking; the small size of the structure is especially beneficial to improve the hook stroke.

Gantry cranes can be easily split into several easy-to-transport sections and assembled quickly in another location, a feature that is beneficial in many situations. I-beam steel gantry cranes can weigh up to 2,000 kg.gantry crane supplier

The wall-type cantilever crane is a new type of material lifting equipment developed on the basis of the wall-column cantilever crane. The traveling track of the machine is installed on the cement column of the factory building, and can be longitudinally moved along the track, and the electric hoist can complete the lateral movement along the selected cantilever and the vertical lifting. The machine greatly expands the scope of work, more efficient use of the plant space, and the use effect is more ideal.

Light crane working principle and structure type

Uncategorized

The light crane adopts a unique design concept with 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, and the clearance height is the lowest. The Keli crane is closer to the front work, and the lifting height is higher, which actually increases the effective working space of the existing plant. Due to the light weight and low wheel pressure of the light crane, the new plant can be designed to be smaller and more complete.light crane manufacturer

Light crane working principle

It can be divided into two categories: one is centralized driving, that is, one motor drives the long drive shaft to drive the active wheels on both sides; the other is driven separately, that is, the active wheels on both sides are driven by one motor. Medium and small bridge cranes use the “three-in-one” drive method in which the brakes, reducer and electric motor are combined. The common bridge crane with large lifting weight is easy to install and adjust, and the drive unit often adopts universal joint. .

Light crane structure type

The crane operating mechanism generally uses only four active and driven wheels. If the lifting weight is large, it is common to increase the wheel to reduce the wheel pressure. When the number of wheels exceeds four, the articulated equalization frame device must be used to evenly distribute the load of the crane on each wheel.

The metal structure of the bridge consists of main beam and end beam, which are divided into two types: single main beam bridge and double girder bridge. The single main girder bridge consists of a single main beam and end beams on both sides of the span. The double girder bridge consists of two main beams and end beams.

The main beam is rigidly connected to the end beam, and the ends of the end beam are provided with wheels for supporting the bridge to run on the elevated frame. The main beam is welded with a track for the lifting trolley to run. The main types of the main girder of the bridge are more typical of box-shaped structure, four-truss structure and hollow truss structure.

The box-shaped structure can be further divided into two types: a normal-rail box-shaped double beam, a deviated rail-shaped double-beam, and a deviated box-shaped single main beam. The normal-rail box-shaped double beam is a basic form widely used. The main beam is composed of upper and lower flange plates and vertical webs on both sides. The trolley rail is arranged on the center line of the upper flange plate, and its structure is simple. It is easy to manufacture and suitable for batch production, but its weight is large.

The cross-section box-shaped double-beam and the off-track box-shaped single main beam are composed of upper and lower flange plates and unequal-thick main and auxiliary webs. The trolley rails are arranged above the main webs, and the short-boosting of the casings The plate can be omitted, wherein the single-segment box-shaped main girder is replaced by a wide-flange box-shaped main beam instead of two main beams, and the self-weight is small, but the manufacturing is complicated. The four-truss structure is composed of four flat trusses combined into a closed space structure. The upper horizontal truss surface is generally covered with a walking platform, which has light weight and high rigidity. However, compared with other structures, the outer dimensions are large, the manufacturing is complicated, and the fatigue is complicated. Low strength and less production.

The hollow truss structure is similar to the derailed box-shaped main beam. It consists of four steel plates and a closed structure. Except for the main web, which is a solid abaxial I-shaped beam, the other three steel plates are cut into many windows according to the design requirements to form a non-slanting rod. The fasting truss is provided with a walking platform on the upper and lower horizontal truss surfaces. The crane running mechanism and electrical equipment are installed inside the bridge. The self-weight is light and the overall rigidity is large. This is a widely used type in China.crane manufacturers

Ordinary bridge cranes are mainly driven by electric power, usually operated in the driver’s cab, and also controlled remotely. The lifting capacity can reach 500 tons and the span can reach 60 meters.

Simple girder cranes, also known as girder cranes, have a structural composition similar to that of ordinary bridge cranes, with small weight, span and working speed. The main beam of the bridge is a simple section beam composed of I-beam or other steel and sheet steel. The chain hoist or electric hoist is equipped with a simple trolley as the lifting trolley. The trolley generally runs on the lower flange of the I-beam. The bridge can be run along an elevated track or along a track suspended below the elevated frame. This type of crane is called a suspended beam crane.

Metallurgical special bridge cranes can participate in specific process operations in the steel production process. The basic structure is similar to that of ordinary bridge cranes, but special working mechanisms or devices are also installed on the lifting trolleys. The working characteristics of this kind of crane are frequent use, poor conditions and high working level. There are five main types.

The jib crane lifting equipment

Uncategorized

The more large the project, the more it will use some lifting equipment. The jib crane is mainly used in engineering. So, how can we play its role in engineering? Let’s take a closer look at how it works correctly.crane manufacturers

The jib crane lifting equipment

The jib crane has a larger span and is economical and durable. It has a built-in walking mechanism and is smaller in size, which is particularly advantageous for improving the travel of the hook.

In the jib crane, the steel bars obtained by it are all disposed at the root of the cantilever of the bridge. However, the current calculation program often only pays attention to the distribution of the longitudinal bending reinforcement on the bottom of the box girder, although the longitudinal reinforcement according to the calculation has been matched. foot.

However, according to the characteristics of the actual force situation, the stress concentration occurs at the root of the cantilever side web, and the gradual decrease on both sides of the web root is reduced. If it is designed according to the conventional design, the longitudinal force-reinforcing steel bar in the cantilever side web is unreasonable, which leads to insufficient bending resistance of the root of the side web of the cantilever plate of the cantilever beam and cracks.

The jib crane is used in engineering applications. It is designed to take into account the stiffness and strength of the port crane work.

Moreover, under the action of any load, the cantilever beam of the jib crane can obtain large deformation by bending, and provides a versatile method to obtain large deformation. The jib crane can also be obtained smoothly by the deflection of the section.

As a common crane equipment, the cantilever crane must have a strict posture and careful observation during use to avoid accidents and reduce costs. gantry crane supplier,Therefore, the following points should be noted during the operation of the boom crane:

1.The bumper or baffle at both ends of the cantilever I rail is used only for unrestricted positions. It is not allowed to be used as a normal parking method during normal operation and is not suitable for frequent collisions.

Points should be noted during the operation of the boom crane

2.Sometimes in order to protect the equipment on the cantilever crane from corrosion, it is necessary to periodically accumulate the polymer on the track and apply some anti-rust oil. The operator of the jib crane should strictly abide by the operating procedures. No-load operation should be carried out before each use of the cantilever crane, and it is checked whether the rotation, operation, lifting, limit and other mechanisms are normal. If an abnormality is found, the machine should be shut down for inspection before it can be used.

3.In the cantilever crane, it is not allowed to tilt and lift heavy objects. It is forbidden to use the hook to drag heavy objects along the ground or forcibly lift the buried heavy objects. It is also not allowed to use the local swivel arm to drag or hit the work.best overhead crane supplier

Also in the jib crane, after the operation is completed, the weight should be removed to avoid deformation of the mechanism for long-term suspension. In addition, the following stations are strictly forbidden during operation and some devices are installed to avoid accidents during construction.

The Risk Factors of the Real Estate (II)

Uncategorized

Generally speaking, the employment center area provides a demand market for residential areas, and the residential area provides sufficient labor for the employment center area, which also creates conditions for the rapid development of shops. The rise of shops will start the second boom in residential and employment. In particular, the quality and price of new properties will increase significantly, which in turn will make the value of shops even more impressive. However, if the shops in the investment community need to be more cautious, on the one hand, the flow of people is limited; on the other hand, the consumption of households in the community is only convenient, and it is difficult to have sustained and large-scale consumption. The shops in the community suitable for investment should generally have a large enough scale, or an open-plan community with spacious block roads.

2.The environment

Improvements in environmental conditions such as ecology, humanities, and economy will increase the value of the property. The ecological environment depends on whether the community can improve the climate due to changes in green space. It is necessary to pay attention to the guiding function of urban planning and try to avoid choosing residential buildings located in industrial areas. Every community has its own cultural background. The higher the cultural level of the community, the more value the real estate has. The investment in shops depends on whether the surrounding business environment has formed a mature business district. If it is affirmative, the appreciation of the store is unquestionable. galvanized steel coils

3.Building quality

For properties with investment value, one must have durability. The more durable the property, the more the investor will save and the more rewards the investor will bring. Durability is embodied in: Firstly, the material of the property must withstand the test of time, if it is real. Secondly, the property manufacturing process should be fine. Thirdly, the equipment of the property must be durable and efficient. Fourthly, there is good property management, which is equivalent to a support system for the repair and maintenance of fixed assets.
