[0002] Tower cranes are also called tower cranes. They originated in Western Europe and are rotating cranes with booms mounted on the top of tall towers. Tower cranes are composed of three parts: metal structure, working mechanism, and electrical system. The metal structure includes the tower, boom, and base. Tower cranes are independent construction equipment. The equipment is fixed on an independent foundation and is raised by adding standard sections to achieve vertical lifting of the equipment at different heights of buildings.

[0003] The existing tower cranes are high in height, difficult to assemble, and have high overall transportation costs. In addition, when in use, people need to climb from the bottom to the top of the cab to operate. The climbing process involves vertical movement up and down, which is very dangerous. For this reason, we propose a detachable standard section inclined ladder and tower crane. Utility Model Content
