Sevencrane multipurpose gantry crane

Industrial multipurpose gantry crane price can be classified according to the structure of the door frame, the form of the main beam, the structure of the main beam, and the form of use.

1. According to the door frame structure

Divided into gantry cranes and cantilever gantry cranes

Sevencrane multipurpose gantry crane for sale
1. 풀 갠트리 크레인: 메인 빔에 돌출부가 없고 트롤리가 메인 스팬 내에서 움직입니다.
2. Semi-gantry crane: The outriggers have height differences, which can be determined according to the civil engineering requirements of the site.

캔틸레버 갠트리 크레인
1. Double cantilever gantry crane: The most common structural form, the stress of the structure and the effective use of the site area are both reasonable.
2. Custom multipurpose gantry crane supplier: This structural form is often selected due to site restrictions.

2. According to the main beam form

1. 단일 메인 빔
단일 주 대들보 갠트리 크레인은 구조가 간단하고 제작 및 설치가 용이하며 질량이 작습니다. 주 거더는 대부분 편향 상자 프레임 구조입니다. 이중 주 대들보 갠트리 크레인에 비해 전체 강성이 약합니다. 따라서 이 형태는 리프팅 용량 Q≤50t, 스팬 S≤35m일 때 사용할 수 있습니다. 단일 대들보 갠트리 크레인 도어 다리는 L 유형과 C 유형으로 제공됩니다. L형은 제작 및 설치가 용이하고 내응력성이 우수하며 질량이 작습니다. 그러나 물품을 들어 올려 다리를 통과시키는 공간은 상대적으로 작습니다. C자형 다리는 경사지거나 곡선형으로 제작되어 측면 공간이 더 넓어져 물품이 다리를 원활하게 통과할 수 있습니다.

2. 더블 메인빔
Double main girder gantry cranes have strong load-bearing capacity, large spans, good overall stability, and many varieties. However, compared with single main girder gantry cranes with the same lifting capacity, their own mass is larger and the cost is higher. According to the different main beam structures, cost multipurpose gantry crane cost can be divided into two forms: box beam and truss. Generally, box-shaped structures are used.

3. According to the main beam structure

1.트러스빔
앵글강이나 I빔을 용접한 구조형태는 저비용, 경량, 내풍성이 좋은 장점이 있습니다. 그러나 트러스빔 역시 용접점이 많고 트러스 자체의 결함으로 인해 처짐이 크고 강성이 낮으며 신뢰성이 상대적으로 낮고 용접점을 자주 검출해야 하는 등의 단점도 가지고 있다. 안전 요구 사항이 낮고 리프팅 용량이 작은 현장에 적합합니다.

2.박스빔
Steel plates are welded into a box structure, which has the characteristics of high safety and high stiffness. Generally used for large-tonnage and ultra-large-tonnage gantry cranes. As shown in the picture on the right, MGhz1200 has a lifting capacity of 1,200 tons. It is the largest gantry crane in China. The main beam adopts a box girder structure. Box beams also have the disadvantages of high cost, heavy weight, and poor wind resistance.

3.벌집빔
일반적으로 "이등변 삼각형 벌집 빔"을 말하며 메인 빔의 끝면은 삼각형이며 양쪽 경사 웹에 벌집 구멍이 있으며 상부와 하부에 코드가 있습니다. 허니컴빔은 트러스빔과 박스빔의 특성을 흡수한 것입니다. 트러스 빔과 비교하여 강성이 더 크고 처짐이 적으며 신뢰성이 더 높습니다. 그러나 철판 용접을 사용하기 때문에 자중 및 비용이 트러스빔에 비해 약간 높다. 사용 빈도가 높거나 무거운 물건을 들어올리는 현장이나 빔 현장에 적합합니다. 이 빔타입은 특허제품이기 때문에 제조사가 적습니다.

4. According to the form of use

1. 일반 갠트리 크레인
This kind of crane mostly adopts box type and truss type structure, and has the most wide range of uses. It can handle various finished items and bulk materials, with a lifting capacity of less than 100 tons and a span of 4 to 39 meters. Ordinary gantry cranes with grab buckets work at a higher level. Ordinary gantry cranes mainly refer to hook, grab, electromagnetic, and hoist gantry cranes, and also include semi-gantry cranes.

2.Hydropower station cost multipurpose gantry crane cost
It is mainly used for lifting, opening and closing gates, and can also be used for installation operations. The lifting capacity reaches 80~500 tons, the span is small, 8~16 meters, and the lifting speed is low, 1~5 meters/min. Although this kind of crane is not frequently lifted, the work is very heavy once it is used, so the work level must be appropriately increased.

3. Shipbuilding gantry crane
Used to assemble the hull on the slipway, there are always two lifting trolleys: one has two main hooks, running on the track on the upper flange of the bridge; the other has a main hook and an auxiliary hook, on the lower flange of the bridge. Run on rails to flip and lift large hull segments. The lifting capacity is generally 100~1500 tons; the span is up to 185 meters; the lifting speed is 2~15 meters/minute, and there is also a micro-movement speed of 0.1~0.5 meters/minute.

4. 컨테이너 갠트리 크레인
Used in container terminals. Container track gantry crane unloading the quay wall container carrying bridge from the ship with a trailer
After being transported to the yard or rear, they are stacked by a container gantry crane or directly loaded onto a truck for transportation, which can speed up the turnover of container carrying bridges or other cranes. Stacking yards that can stack containers with 3 to 4 layers in height and 6 rows in width usually use tire type, but rail type is also used. Compared with container straddle trucks, container gantry cranes have larger spans and heights on both sides of the mast. In order to meet the transportation needs of port terminals, this kind of crane has a higher working level. The lifting speed is 8~10 meters/min; the span is determined according to the number of rows of containers that need to be spanned. The maximum is about 60 meters, corresponding to the lifting weight of 20-foot, 30-foot, and 40-foot long containers of about 20 tons and 25 tons respectively. and 30 tons.
