Dear sea friends, do you use tower cranes for the installation of steel structures in your projects?

Our company has never used tower cranes in steel structure installation; we have always used truck cranes or crawler cranes instead. But I’ve seen some construction companies use tower cranes; I think the tonnage should be determined based on the maximum weight of the steel structures, as the lifting methods are more or less the same.

Whether to use a tower crane depends on the volume of work involved in the structure’s construction as well as the installation requirements; if the height is great and the structural weight is heavy, then a tower crane is generally an appropriate option. For small-scale structures, a truck crane is sufficient; tower cranes are better suited for construction projects with longer timelines and those that involve the use of many machines. Truck cranes are ideal for installing small-scale structures, especially when the prefabricated components are quite large, as this allows for centralized lifting and thus helps to reduce machinery costs. Currently, there are two types of tower cranes in use in China: one is of the cylindrical type, and the other is of the cantilever type. The most widely used is the cantilever type. It is easy and flexible to use. Moreover, it has a wider coverage area. If the weight to be lifted is large and the machinery is used frequently, using a tower crane is more cost-effective compared to a crane. When selecting a tower crane, two points need to be considered: First, determine preliminarily where the crane will be installed. As a general rule, it is advisable that the crane’s swing radius be as close as possible to the components to be installed; however, consideration also needs to be given to the installation of the crane and its attachments, as well as its subsequent removal. Second, based on the preliminary location determined for the tower crane, determine the maximum weight of the components at the greatest distance; the specifications of the tower crane are then set according to the maximum weight of the components at that farthest rotation radius. I have experience using 400T tower cranes and 750T tower cranes. Their service life is quite long, reaching one and a half years, which makes them quite cost-effective compared to using large cranes.

Crane towers are frequently used in steel structure installation, as they represent the most economical cost for such machinery. Of course, it is generally used for longer construction periods, with appropriate component weights and structural forms.

Crane towers are generally not used; instead, truck cranes are employed as they are more convenient and flexible. However, it is harder to find ones with a high lifting capacity.

The friend on the 3rd floor explained it very clearly – learn *. One project I was involved in involved the framework for an aromatic compounds processing unit; it was 96 meters high and made of entirely steel. We initially planned to use tower cranes for construction, but in the end we didn’t do so. The reason was that at that time it was the period when the large equipment for the entire unit was being installed, and there were many cranes available – 1250-ton cranes, 500-ton cranes, and 400-ton cranes as well. We decided to use these cranes for the work at higher heights, to pre-fabricate the components there first, and then use those crawler cranes to lift them into place ； For installation at low heights, we use our unit’s 200-ton truck crane. In this way, making rational use of existing resources is also one of the aspects that contribute to the success of this project.

We have few steel structure factories here, but many steel structure supports, which are scattered throughout. Prefabricated components are transported to the site using gantry cranes, while truck cranes are used for delivery on-site. The crawler crane has never seemed to be used

We use truck cranes for our steel structures; tower cranes are suitable for lifting heavy loads over extended periods of time, while truck cranes are more convenient and flexible. Steel structures are usually prefabricated in advance, and it takes only a few days for cranes to complete the lifting process. Tower cranes are mostly used in factory building construction.

The use of tower cranes depends on the specific circumstances; currently, they are widely used in the installation of steel structures for power plant boilers, as well as in the construction of accessories and furnace tubes for ethylene cracker units, where there is a large volume of lifting work to be done
