Single girder overhead crane is the most effective hoisting equipment used in plant or workshop. Overhead crane can travel on top of runway, so it’s also called bridge crane. There is also another type of overhead crane called single girder underhung/suspension crane. It travels under the runway which is fixed on roof of plant. With single girder overhead crane, you can achieve six motions: up, down, left, right, forward,back.

Building materials, logistics, warehousing, engineering, metallurgy, power industry, chemical industry, steel storage, open storage areas, cargo yard etc.

Compact design, small deadweight, large capacity, easy operation, non-stop run, design lifespan 20 years.

Based on different requirements of site, we can offer suitable solution and proposal.

Technical design base:

Capacity: According to weight of lifting load, working environment, plant structure load capacity, crane wheel pressure and so on. Our single girder overhead crane can be designed up to 20t capacity. Single girder underhung/suspension crane can be designed up to 10t capacity.

Span: According to distance between runways or columns in workshop, our engneers can derive specific technical scheme. Further more, if customer can provide layout of the plant, our engineer will offer precise and economic solution. Generally, span of crane can be up to 31.5m and available for customized span.

Lifting height: According to distance from roof top to ground in workshop, our engneers can confirm lifting height needed. Also, height from roof top to runway will be very important for installation. If customer can provide drawing of the plant section, we can find better choice for you.

Power supply: Power grid is very different from country to country. To insure our equipments have stable and reliable performance, please inform us local power supply conditions. For example: Voltage 220v,380V, 400v, 415v or 440v. Frequency 50Hz/60Hz. 3 phase.

Control method: Pendant control, remote control(wireless radio control), cabin control.

Our single girder overhead crane apply measures as below to insure crane safety during operation:

• Overload limiter, for lifting safety.
• Electromagnetic brake, quick response, up to 1000000 times braking lifespan.
• Limit switch for long traveling.
• Welding quality inspection, guarantee load capacity of main girder and end beam/carriage.
• Thermal electromechanical protector.
• Electrical protection system.
