how to choose a suitable pillar jib crane

How to choose the type of pillar jib crane?

The choice of pillar jib crane is mainly considered the following three questions: mechanical, mobility and stability. It is more appropriate to choose a truss arm (mechanical transmission) or a box type telescopic boom (hydraulic transmission) pillar jib crane. Whether to use a professional jib crane?

1. Because of material handling, sporadic hoisting and the need to quickly enter the construction work, the choice of truck pillar jib crane is appropriate. It is more advantageous to use a hydraulic motor vehicle with a telescopic boom and a landing leg. For the need to put the telescopic arm into the window or hole working , the hydraulic truck pillar jib crane is the most ideal lifting equipment.
   
   
2. It can be based on the existing mechanical conditions for the use of crawler or tyre type pillar jib crane when the lifting project requires a large weight, high installation height and big amplitude change. On the other hand. If the ground is soft and the driving condition is bad, the crawler pillar jib crane is the most suitable choice. If the ground is not allowed in the operating range, the use of the tyre type jib crane is the best.
   
   
3. When the construction condition is limited, it is required that the crane load travel operation (It is dangerous, if it is unavoidable to work, the weight should be in accordance with the instructions of the use of the machine)can choose a crawler or a rough terrain pillar jib crane. The maneuverability of the rough terrain pillar jib crane is better, and the stability of the crawler jib crane is higher.
   
   
4. Specialized operation should choose the professional pillar jib crane. Such as the short distance of the scattered commodity to carry, can be chosen to use the truck mounted pillar jib crane installed on vehicle (YD type),so it is needed for the two machines to complete the work originally, but now can be replaced by one single.
   
   
5. The best choice for multi use, efficient, energy-efficient pillar jib crane products. Such as construction sites requires both self lifting and lifting by a tower type pillar jib crane ,in this case, the use of a self- propelled tower type pillar jib crane should be chosen, in order to save the investment of mechanical units.
   
   

How to choose the capacity of pillar jib crane ?

According to the weight and the lifting height, also taking into account the other conditions of the site, the suitable specifications can be found from a sample or technical performance table of a movable pillar jib crane. Due to the bigger lifting weight of the crane, it is more difficult to make full use of its various performance in the lifting project, and the lower utilization rate. Therefore, as long as it can meet the technical requirements of lifting, the pillar jib crane is best choice and that needn’t to choose a large capacity crane.

The choice of economic performance of pillar jib crane girder

The principle of selecting the integrated economic performance of self-propelled type pillar jib crane is that it has the lowest unit price, such as the material or component costs in the transportation, lifting, loading and unloading ,etc. So we can use the norm of the lifting weight ( or the productivity of a contract ) and the cost of machine-team ( or the cost of the provisions of the contract ) to calculate the unit price of material transportation, then choose the lowest one. In addition, we should also consider the lowest energy consumption and more functions products, to reduce labor intensity. In short, only when we choose the most suitable pillar jib crane and model specification that provides the most effective use, can we obtain the maximum effectiveness.
