Introduction and Working Characteristics of Top Running Cranes

Top running crane is a lifting equipment that is placed horizontally over workshops, warehouses and yards for lifting materials. They are mounted on rails on top of the building’s support structure, allowing the crane to move along the length of the building. Top running overhead crane is the most commonly used crane type which has a fixed track system installed on the top of each runway beam. The lifting capacity of 탑 러닝 오버헤드 크레인 will not be limited and it can be manufactured to lift loads from 1 ton to 450 tons. Since the top running crane is supported by steel support columns or existing concrete steel building support structures, it is very suitable for moving extremely heavy loads. What’s more, the heavy duty top running crane cost reasonable and help to save factory space for you.

The crane and trolley are suspended from main beams that span the width of the building. Top running bridge crane is a kind of lifting machinery with wide range of use and large quantity. Top running cranes are important tools and equipment for mechanizing and automating the production process in modern industrial production and lifting transportation. They can reduce the labor intensity of operators and improve productivity. Top running cranes are widely used in industrial and mining enterprises, steel and chemical industries, railway transportation, ports and terminals, logistics turnover and other departments and places. It is an indispensable piece of equipment in people’s production activities.

There are many types of top running cranes, among which general bridge cranes and gantry cranes are more common. The structures and operating methods of these two types of cranes are basically the same. The difference lies in the position of the trolley running track. The industrial electric top running crane for sale is at high altitude. The gantry crane is on the ground, which brings about different support structures.

Although there are different types and models of top running bridge cranes, with differences in appearance and structure, they all have one thing in common, which is the intermittent working method. A working cycle generally includes: displacing the material through the lifting and lowering of the fetching device, and then moving in the opposite direction to return to the original position or another position for the next working cycle. Between the two working cycles, time, usually a short interval. It can be seen that when the top running bridge crane is working, each mechanism is often in alternating motion states of starting, running, braking, and forward and reverse phases. In addition, top running overhead cranes also have the following working characteristics:

1. Hoisting machinery usually has a huge metal structure and a relatively complex mechanical structure. It can complete one lifting, lowering or several horizontal movements. During the operation, there are often several movements in different directions at the same time, which is technically difficult.

2. 들어올리는 자재도 다양하고, 하중도 다양합니다. 무게는 수십 톤, 심지어 수백 또는 수천 톤에서 수십 킬로그램의 가벼운 무게까지 다양합니다. 길이는 수십 미터에서 1미터 미만까지 다양합니다. 그리고 모양도 다양할 수 있어요. 과립형, 핫멜트형, 가연성 및 폭발성 물질뿐만 아니라 규정으로 인해 리프팅 작업이 복잡하고 위험해졌습니다.

3. 대부분의 크레인 장비는 넓은 범위 내에서 작동해야 하며 일부에는 레일, 강철 바퀴 또는 타이어형 크롤러가 장착되어 이동 공간이 넓고 위험 표면이 넓습니다.

4. 노출된 움직이는 부품이 많아 리프팅 인력(예: 후크 및 로프)과 직접 접촉하는 경우가 많습니다.

5. 작업 환경이 복잡합니다. 산업 및 광업 기업, 항구, 건설 현장 및 기타 장소에서 리프팅 장비가 작동 중입니다. 또한 작업 중에는 고온, 고압, 인화성, 폭발성, 송전선, 강한 자기장 등과 같은 위험한 요소가 발생합니다. 이러한 불리한 조건은 사람과 장비 모두에 해롭습니다.

6. 작업에는 사람의 협력이 필요한 경우가 많으며 매우 어렵습니다. 대원과 지휘관은 서로 협력하고, 협력하고, 능숙하게 보살펴야 합니다. 운영자는 현장 응급 상황에 대처할 수 있는 능력을 갖추어야 합니다.

With the rapid development of modern industry and the continuous advancement of science and technology, some new changes and new characteristics have appeared in the structural design and degree of automation of overhead cranes.

For example, in terms of structure, the custom top running crane manufacturer uses computer optimization design to improve the mechanical performance of the crane and reduce its own weight. In terms of performance, we continue to introduce advanced foreign technologies and adopt novel energy-saving speed regulation systems, such as thyristor cascade open-loop or closed-loop systems. The speed regulation ratio can reach 1:30. As the requirements for speed regulation increase, variable frequency speed regulation systems And microcomputer control technology has also been applied in cranes.

In short, with the rapid development of science and technology, various domestic advanced electrical control and mechanical technologies are gradually being applied to cranes, and the cranes produced by SEVENCRANE top running crane factory  are becoming more and more automated, with increasingly simpler structures, more reliable performance, and higher lifting capacity It’s getting bigger and bigger, and the variety is getting more and more complete.
