MHS Electric Hoist Double Beam Gantry Crane
HS type electric hoist double beam door type crane model routine configuration: ground exercise or room operation, single speed or double speed wire rope hoist, large, small car can use single speed rat cage motor or winding motor. Chauffeur room separate and closed two kinds. The working level is A3~A4, and the working environment temperature is -200C~+400C. This type is not recommended for hoisting hot metal or toxic hazardous substances. It is not suitable for working environment with explosion-proof and insulation requirements.
The function and characteristic of crane
Gantry crane is a deformation of bridge crane, also called gantry crane.Mainly used for outdoor yard, yard cargo, bulk cargo handling operations.Gantry cranes are widely used in port yard due to their high utilization rate, wide range of operation, wide adaptability and strong versatility.
Its metal structure is like a portal frame, bearing the main beam under the installation of two legs, can be directly on the ground on the track, the main beam at both ends can have an overhanging cantilever beam.
Crane parameters and details
Gantry crane is also A gantry crane working level A: it reflects the crane in the state of load and the use of two aspects of the busy working characteristics.
Single girder gantry crane is simple in structure, convenient in manufacture and installation, low in quality.Compared with the double girder gantry crane, the overall stiffness is weaker.Therefore, when lifting weight Q 50t and span S 35m, this form can be adopted.Single girder gantry crane gantry legs have L and C two forms.The L type is easy to manufacture and install, with good stress condition and small weight. However, the space for lifting goods through the leg is relatively small.The legs of type C are inclined or bent so that there is a large horizontal space for the goods to pass through the legs.
The double girder gantry crane has strong bearing capacity, large span, good whole stability and many varieties, but its own quality is larger than the single main beam gantry crane with the same weight, and the cost is higher. According to the main girder structure, it can be divided into two forms: box girder and truss. Generally, the box structure is usually used at present
1. Gantry crane: the main beam is not overhanging, and the trolley is carried out within the main span;
2. Half-gantry crane: the supporting legs are different in height, which can be determined according to the civil construction requirements of the site.
Jib gantry crane
1. Double cantilever gantry crane: the most common structural form, its structural stress and effective use of site area are reasonable.
2. Single cantilever gantry crane: this structural form is often chosen due to site constraints.
