Which type of crane is typically used for lifting heavy loads vertically and horizontally at construction sites?

The tower crane is specifically designed for the construction industry to lift and move heavy loads both vertically and horizontally. It has a vertical mast that provides stability and reaches significant heights, allowing it to lift heavy materials to upper floors of tall buildings. The horizontal jib can extend outwards, enabling the crane to place materials at various locations on the construction site.

One of the main advantages of tower cranes is their ability to maintain a compact footprint while having a high lifting capacity, making them ideal for urban construction where space is limited. Their design allows them to operate efficiently without the need for continuous relocation, further streamlining construction operations.

In contrast, mobile cranes are versatile and can travel over roadways, while crawler cranes have tracks for improved stability on soft ground, but they generally are not used for the high-rise lifting capabilities provided by tower cranes. Knuckle boom cranes are more suited for load handling in tight spaces and for tasks that require precision rather than the large-scale lifting performed by tower cranes. Therefore, for lifting heavy loads vertically and horizontally on construction sites, tower cranes are the most appropriate choice.
