Grab Overhead Crane Product Introduction
Underhung overhead cranes are a type of light and small bridge cranes with rail operation.It is widely used in machining, assembly, repair, and warehouses, and is used for lifting and handling heavy objects.As the name suggests, the underhanging crane is suspended on the roof structure of the building and runs on the bottom flange of the track beam.
Single-beam suspension cranes are designed and manufactured in strict accordance with the industry standard JB2603-94, and are usually equipped with AQ-CD and AQ-MD electric hoists.Due to the special structure, downstream bridge cranes usually use a single-beam design, so the lifting weight is not large.The lifting weight range is 0.5 tons to 10 tons, the span is 3-22.5 meters, the working level is A3-A4, the working ambient temperature is -20-40 degrees Celsius, and the relative humidity is ≤85%. Work under environmental conditions without flammable, explosive and corrosive media.
Underhanging cranes can also provide excellent lateral approach capabilities and maximize the width and height of the building when supported by the roof or ceiling structure. They are ideal for facilities that lack vertical space to install and run bridge crane systems on top.
How Much Does Underhung Overhead Cranes Cost
The price of underhung overhead cranes will vary depending on factors such as lifting capacity, span length, and work level. The following is the price list of some underhung overhead cranes：
| Underhung Overhead Crane | Span/m | Working System | Power Supply Voltage | Price/USD |
|---|---|---|---|---|
| 1 Ton | 7.5-28.5 | A3 | three-phase 380v 50Hz | $1,820-5,230 |
| 2 Ton | 7.5-28.5 | A3 | three-phase 380v 50Hz | $2,040-6,090 |
| 3 Ton | 7.5-28.5 | A3 | three-phase 380v 50Hz | $2,130-7,470 |
| 5 Ton | 7.5-28.5 | A3 | three-phase 380v 50Hz | $2,570-8,370 |
| 10 Ton | 7.5-28.5 | A3 | three-phase 380v 50Hz | $3,770-9,720 |

Top Running Ceanes VS Underhung Overhead Cranes
| Parameter | Top Running Cranes | Underhung Overhead Cranes |
|---|---|---|
| Runway beams installation method | The top running cranes are mounted on the top of the bridge girder. | Underhung overhead cranes are mounted to the bottom of the bridge girder. |
| Capacity | Larger weight below 20t | Below 10t |
| Hook operation interval | Smaller | Larger |
| Hook height | High | Low |
| Work level | Light | Light |
| Cost (comparison with specifications) | Same | Same |
| Most suitable for the scene | Small workshop, assembly line. | Coal silos in thermal power plants and pump houses in sewage treatment plants. |
| Installation conditions | Need column crane beam system. | The top of the plant needs to have a bearing structure. |
In summary, if your plant space is limited, you can choose a hanging crane. If you need to lift heavy objects of more than 10 tons, it is a better choice to run a crane on top of work in small workshops, assembly lines and other industries.
The roof of the workshop has a carrying beam, which rotates down; the roof of the workshop does not have a carrying capacity, but the ground of the workshop has a column crane beam system installed, using top running crane.
