LX Traditional Single Girder Suspension Crane

Traditional single girder suspension crane

The single girder suspension crane is designed according to international standards. It is a kind of light duty material handling single girder overhead crane, with single girder running on the suspension track, and usually equipped with CD1 and/or MD1 type electric hoist. The lifting capacity of the single girder suspension eot crane is 1 – 10 ton, and the span is 3 to 15 m, and the traveling speed is 20 m/min and 30m/min. Custom desigend overhead crane is provided according to application conditions and customer requirements.

Main parameters of traditional single girder suspension crane

  • Product Type : LX Traditional single girder underhung / underslung crane
  • Lifting capacity of underhung crane: 1~10t
  • Span length of underhung crane: 3~15m
  • Working class of underhung crane: A3
  • Ambient temperature of underhung crane: -20~40℃

Suspension crane is usually designed in single girder configuration for lighter service and lower-capacity lifting applications. When it is designed in double girder, it also can handle loads with higher capacity, but it will be impractical and expensive.

Single girder suspension crane

A single girder suspension crane usually select the under running electric hoist and trolley as the lifting mechanism to moves across the bottom flange of the bridge beam.

Double girder suspension cranes

A double girder suspension crane can run its electric hoist and electric trolley along on the top or the bottom of the bridge beams.

Basic structure of single girder suspension crane

The single girder suspension crane also called underhung craneis consisted of main girder, cross beam, electric hoist, electric parts, lifting mechanic devices, etc.

Application of single girder suspension crane

The light duty crane is usually used in the working environment with no combustible, explosive or corrosive substance or media, such as, machinery assembly, warehouse, caves, etc.

Main features of single girder suspension crane

  1. One type of main girder is consisted of I-beam and channel, used for lifting small tonnage loads and the other type is consisted of U shaped steel and I- beam, used for large tonnage loads.
  2. All the hoist and crane movements are independent and can be run simultaneously.
  3. Electric hoist mobile power supply is constituted by flat cables or special cables.
  4. The electric hoist can be selected according to your requirements.
  5. Ground control method: pendant and remote control.

Advantages of single girder suspension crane

  1. High safety and reliability
  2. Tight structure and good rigidity
  3. Flexible operation and low maintenance
  4. Low noise and no pollution
  5. Wide selection and application
  6. Smoothing moving, effectively braking and long service life.
  7. High quality and cost-effective crane price.

Single girder underhung/ underrunning crane v.s Top running single girder crane

An suspension crane, or under-running overhead crane rides on the lower flange of the beam, comparing with a top running overhead crane.

On crane i beam & Crane tracking

An suspension crane outcomes the top running crane in that the suspension crane experiences fewer tracking problems than a top-running crane due to the suspension crane is bolted to the I-beam, which is secured to the building structure. Whereas, it also limits the overhead crane crane’s movement and lessens the chances of rail misalignment.

On realignment

But when an suspension crane system does require realignment, the required downtime may be greater than for a top-running crane system, due to suspension and rigging required for alignment of an underhung system. In contrast, while top-running crane systems require more frequent rail alignment checks and more frequent rail alignment, they are easier service.

Suspension crane: single girder or double girder design?

Suspension cranes is usually designed in single girder configuration for lighter service and lower-capacity lifting applications. When itis designed in double girder, it also can handle loads with higher capacity, but it will be impractical and expensive.

Suspension crane saves your floor space with existing structures

Due to the suspension crane is supported by the existing ceiling trusses or the roof structure, it will helps to maximize the floor space of your facility. Suspension cranes provides excellent side approach and makes the most of your facility’s width and height for being supported by roof or ceiling structures. Suspension crane is the first choice for facilities with limited vertical clearance or headroom to install a top-running overhead crane system.

Free standing designs for factory with no exsting structrues

Suspension cranes also can be used in the facility without existing supporting structures which can support the crane runway. In the condition, it will be designed in a free-standing configuration with the support or mounting columns.

On lifting height of suspension crane

Compared with the top running overhead crane, the suspension crane has less hook height and lift height due to the bridge and electric hoist hang underneath the runways.

Installation of suspension cranes

As for installation and service of an suspension crane system, the procedure can be complex and may cause to longer downtime. Because the suspension crane is suspended from the runways, longer time will be taken to check the alignment or service the wheels of the overhead crane, but it is easier to maintain the alignment and cause fewer tracking problems because the I-beam design is secured to building structure—limiting movement

When buying an suspension crane

When buy an underhung overhead crane, the following should be considered:
Is your building’s structure strong enough to support a crane system? If not, a freestanding overhead crane system is an option. The drawback of a freestanding suspension crane system is that it takes up floor space from production and other uses.

Generally, the under running overhead crane flexibility, functionality, and ergonomic solutions, whereas, the top running overhead crane kits is featured of higher capacity lifts and higher lift heights and more overhead room.If you are in need of an overhead crane, and do not how to select from the top running system or under running system, please leave a message below.
