How To Choose A Jib Crane?

How to choose a jib crane?

 

 

The first is to choose the type of cantilever crane. Compared with bridge cranes and gantry cranes, cantilever cranes are more suitable for short-distance, frequent and intensive lifting operations. They are generally divided into three types: column type, wall-mounted type and balance crane. form.

 

① A column-type cantilever crane is a cantilever crane composed of a column and a cantilever whose cantilever can rotate around a fixed column fixed on the base, or the cantilever and the rotating column are rigidly connected and rotate together relative to the vertical centerline in the base support. It is suitable for occasions where the lifting capacity is small and the operating service range is circular or sector-shaped. Generally used for loading and transporting workpieces in machine tools, etc.

 

Column cantilever cranes mostly use electric chain hoists as the lifting mechanism and operating mechanism, while wire rope electric hoists and hand chain hoists are rarely used. Rotation and horizontal movement operations are mostly performed manually, and electric operation is only used when the lifting capacity is large.

 

②A wall crane is a cantilever crane that is fixed to a wall, or a cantilever crane that can run along an elevated track on a wall or other support structure.

 

Wall cranes are used in workshops or warehouses with large spans and high building heights. They are most suitable when lifting operations near the wall are frequent. Wall cranes are mostly used in conjunction with the beam or bridge crane above. They serve a rectangular space near the wall and are responsible for lifting light and small objects. Large objects are borne by the beam or bridge crane.

 

③Balance crane is commonly known as balance crane. It uses the principle of four-bar linkage mechanism to form a balance system between load and balance weight. It can use a variety of spreaders to flexibly and easily lift loads in three-dimensional space. The balance crane is light and flexible, and is an ideal lifting equipment for lifting small items. It is widely used in machine tool loading and unloading in factory workshops, workpieces in process rooms, automatic lines, production lines, sand box lifting, parts assembly, and Stations, docks, warehouses and other occasions.

 

 

Secondly, you need to choose according to your own work needs: lifting capacity, lifting height, working range, working environment, control method, safety performance, maintenance, cost budget, etc.

 

1. Lifting capacity: Determine the lifting capacity based on the weight of the objects that need to be transported. Ensure that the rated lifting capacity of the crane can meet the work needs while leaving a certain margin.

 

2. Lifting height: Determine the lifting height according to the height of the object that needs to be lifted. Make sure the crane's lifting height meets the work requirements.

 

3. Work scope: Determine the work scope according to the coverage area of the objects that need to be moved. Make sure the crane's jib length can reach the area where the object needs to be moved.

 

4. Working environment: Consider the constraints of the crane in the working environment, such as indoors or outdoors, narrow or open space, etc. Choose a crane that adapts to the working environment. For example, outdoor working environments require special designs such as protective covers, rain protection, and anti-corrosion.

 

5. Control method: Choose the appropriate control method according to your needs, such as manual control, remote control, automatic control, etc.

 

6. Safety performance: Ensure that the crane has good safety performance, such as safety limiters, overload protection devices, emergency shutdown devices, etc.

 

7. Maintenance: Consider the difficulty and cost of crane maintenance and choose a crane that is easy to maintain.

 

8. Cost budget: Determine the appropriate crane model and configuration based on the budget.

 

Before choosing, communicate with the jib crane manufacturer or supplier to provide appropriate suggestions and customized solutions based on specific work needs. At the same time, for large or complex projects, conduct site surveys and assessments to ensure the appropriate jib crane is selected.
