Suspension Crane With Cantilever Design, Cantilever Bridge Crane

Suspension Cantilever Bridge Crane, Underslung Bridge Crane with Cantilever Design

The suspension cantilever bridge crane is a underslung bridge crane that suspends and fixes the crossbeam on the building’s steel structure or roof structure. Based on the your lifting requirement, the suspension bridge crane can be design with single cantilever or double cantilever at one or both sides, with the length of 1/3 main girders.

With cantilever design, the suspension bridge crane enables the hoist trolley travelling go beyoud of the main girder, which will enlarge the working space of the overhead cranes.  

Underhang Running Single Girder Bridge Cranes

LX under hung cantilever overhead crane is one kind of light duty crane, it runs under I steel rail . It is designed and made by reasonable structure and higher strength steel .

It uses together with CD1 model MD1 model electric hoist as a complete set, it is a light duty crane with a capacity 0.5 ton ~ 10ton. The span is 5-30m. Working duty is A3~A5, working temperature is -25-40℃.

Advantages and features of LXC electric single girder suspension crane:

• a: The compact and solid bridge crane design increases the available space.
• b: The box-shaped (or welded H-shaped steel) beam designed by computer optimization is used as the main load-bearing beam.
• c: The operating mechanism adopts an internationally accepted hard tooth surface, helical gear, and self-lubricating reducer.
• End carriages design of suspension cantilever bridge cranes
• The features of end beam design of electric single-girder suspension cantilever bridge crane are as following:
• a: Through the cantilever at the side end, the driving range of the trolley can exceed the gauge of the crane, increasing the lifting space.
• b: Due to the unique design of the end beam, the limit size of the hook is small, which can quickly lift heavy objects to the end of the factory building, and can utilize the building area.
• c: It adopts modular design and has high interchangeability. The wheel pressure can be arranged according to the span of the crane to ensure the movement performance.
• d: Stepless speed regulation is adopted to control the walking speed of the trolley, so that the shaking of the heavy lifting is small, the positioning is accurate, and the operation is convenient and reliable.
• e. The electrical components are selected from the world's Schneider products, large-capacity contactors are used, and integrated continuous load electronic monitors are used for overload.
• f. Limit the lifting capacity through the electronic overload switch on the wire rope suspension device.
• g. The brake adopts an automatic conversion device with high-voltage start and low-voltage operation, which realizes the rapid synchronous start and brake of the brake and the drive device.
• h. The electrical connection between the control switch and the running motor and the quick plug-in connection of electrical components make the on-site installation quick and avoid connection errors.
• i. The use of PE corrugated pipe greatly improves the wear resistance, oil resistance, acid and alkali resistance, ultraviolet resistance and flame retardancy of the cable. The protection level is IP68, and the operating environment temperature is -40 ° C ~ 100 ℃.
• j. According to user needs, frequency conversion control of lifting and running motors can be selected.
• k. The remote control can be installed according to the needs. There are German HBC, Taiwan Yuding and other brands for users to choose

According to main girder and hoist type, it separate with two type:

• 1. LX Under Running Cantilever Overhead Crane Single Beam Universal Design
• 2. LXE Under Running Cantilever Bridge Crane Single Beam European Design
• 3. Underhung telescoping cantilever bridge cranes

Under Running  Cantilever  Overhead Cranes Specification:

Underhung telescoping cantilever bridge cranes

The telescoping cantilever bridge cranes are typical designed for limited space workshops or applications. The underhung bridge cranes can extend the lower cantilever outdoor of the crane span or outdoor workshops or any other types of obstacles.

The telescoping cantilever bridge crane with lifting capacity up to 500kg, 1000kg and up most 2 ton, and the cantilever designed length can be the 1/3 of the main girder to ensure safety. If you have any need, please feel free to contact us. The custom design is available.

Under running overhead crane application

A cantilever crane has a wide range of motion and can lift loads in narrow spaces. It can raise loads that are larger than those that can be lifted by a standard bridge crane. The cantilever crane, unlike a standard bridge crane, includes an additional trolley that permits the hook to travel outside of the bridge.

LX type single girder cantilever bridge cranes are mostly used for production and maintenance. They can be used for material handling in places and factories such as, Pre Engineered Steel Building, Steel Plant, Steel Product Maker, Oil Industry, Plastic Plant, Cement Plant, Power Plant, Mine Industry, Food Industry, Chemical Industry, Cable Plant, Machine Tools, Car/Truck Industry, Transport Company, Construction Company, Electrical Company, Shipyard, Stone Yard, Installation and Maintenance, and so on.
