The weight capacities of tower cranes may vary depending on the size, design, and type of cranes. In general, small tower cranes may have a load capacity of 2 tons, whereas large cranes may have a load capacity of 20 tons and more.

Furthermore, the load capacities of tower cranes may vary depending on factors, such as the height and horizontal range of the cranes. The load capacity of the cranes is indicated in the operating manuals of the cranes and it is important to follow this information carefully.

The weight capacities of tower cranes are extremely important for the safe operation of cranes. Operators must not exceed the maximum weight capacities of cranes and must ensure the proper fasting and lifting of the loads. It is also critical to ensure the safe operation of the cranes by regularly maintaining and periodically inspecting.
