Suspension Crane:Single Girder Under Running Bridge Crane with European Style Rope Hoist 500kg -10 T

European single girder suspension crane is a light duty material handling single girder overhead crane designed based on the European standards and FEM standard, with the crane bridge running under the crane rail. Therefore, the single girder suspension crane is also called the single girder under running bridge crane. The European style suspension crane is installed or attached on the ceiling structure or roof structure without any supporting column on the ground, saving space and lowering cost. The hoisting trolley is small and loads can be lifted to the place as near as possible to the wall of the workplace. The traveling range of hoist trolley can exceed crane span trough side jib or jib cantilever. The lifting capacity of European single girder suspension crane is a type of overhead crane with lifting capacity from 1 to 16 ton and the working class is A5.

Features of single girder underhung bridge crane

Generally, electric hoist crane has the following features:

1. On mechanical parts:

• Single main girder, welding box structure and camber meeting national standards.
• Crane driving IP55, F class insulation, contact continuity reaches 40% ED.
• Epoxy zin-rich paint, a long service life, beautiful outlook and lustre.

2. On electrical parts

• Safe slide wire: high conductivity, small voltage drop and swift current collector slide speed;
• Lifting mechanism: independent control system for trolley and crane, synchronous and individual operation is possible;
• Electric control box: reasonable layout, simple maintenance and insulation class IP55;
• Cables: flat cable, galvanized track and cable pulley for trolley traveling power supply;
• Electric contactless module speed regulation controlling.

3. Protection devices

Electric hoist crane has the protection devices, such as, overload warning, secondary class anti-clamp, sound and light alarm devices, circuit self-check protector, and flow phase lack protection, etc.

4. Operation

Electric hoist crane has several operation methods for your selection: ground flashlight door, remoter, flashlight door+remoter, etc.

Application of single girder under running bridge crane

When supporting steel work is not possible and optimum hook coverage is required, suspension cranes are an excellent choice.

Single girder suspension cranes, also known as under-hung, under-running, or suspension cranes, are ideal for factories and warehouses that require a large amount of free space with no obstructions. They allow for more flexible production flow while also improving safety and accessibility when a process necessitates the use of floor-traveling vehicles as well as hoisting cranes. The under running cranes runs on track beams that are part of the building's roof structure, eliminating the need for supporting floor columns. The under slung crane runs on the lower flanges of track beams suspended from the roof or ceiling. Tha’s why, the udnerlusng crane also is called ceiling crane or ceiling mounted crane, etc.

The light duty single girder under running overhead crane is typically used in general use applications and environments that there is no contain combustible, explosive, or corrosive substances or media, such as machinery assembly, warehouses, caves, and so on.

Advantages of single girder under running bridge crane

• Consistent quality is one of the advantages of using a single girder under running bridge crane .
• End truck of the suspension crane is designed with an optimized structure.
• For optimal load distribution, the rigid beam girders or welded box girders are adopted optionally.
• Loads can be handled directly adjacent to the building wall using girder ends that are tailored to the application requirements.

Factors to consider w hen buying a suspension crane

When buy a suspension crane, the following should be considered:

Is the your building structure strong enough to support the weight of suspension crane system and the rated load weight? If this is not possible, a freestanding overhead crane system is an option. The disadvantage of a freestanding crane system is that it takes up floor space that could otherwise be used for production or other purposes.

In general, the single girder under running bridge crane kits have greater flexibility, functionality, and ergonomic solutions, whereas the higher running overhead crane kits have higher capacity lifts, higher lift heights, and more overhead room.
