Types of Tower Cranes:
Self-Erecting Tower Cranes: These cranes are compact, mobile, and can be assembled and disassembled quickly. They are ideal for small to medium-sized construction projects.
Hammerhead Tower Cranes: Featuring a horizontal jib with a trolley that moves the load in and out along the jib, these are commonly used in various construction projects.
Luffing Jib Tower Cranes: Equipped with a jib that can be raised or lowered, these cranes are suitable for sites with limited space or where multiple cranes are in operation.
Flat Top Tower Cranes: Designed without a “cathead” (the assembly at the top of the crane), these cranes are easier to erect and dismantle, making them suitable for projects with height restrictions or multiple cranes.
