Application Of Truck Cranes In High-Rise Building Construction

Truck cranes are a critical piece of machinery in high-rise building construction. The following is a detailed introduction to their application in this field:

1. Material lifting

Building steel lifting: In the early stages of high-rise building construction, a large amount of steel bars need to be lifted to designated floors. With its mobility and flexible boom operation, truck cranes can easily lift bundles of steel bars from the ground to the floors under construction, and can accurately complete lifting tasks around the building foundation pit or in relatively narrow construction sites.

Formwork lifting: The formwork used for pouring concrete is often large and heavy. Truck cranes can lift the assembled formwork to the corresponding floor for installation, and when the formwork is removed, it can be safely lifted back to the ground. The length and lifting capacity of its boom can meet the lifting needs of formworks of different heights and weights.

2. Installation of precast concrete components

Precast beam and slab lifting: With the development of building industrialization, precast concrete beams and slabs are increasingly used in high-rise buildings. Truck cranes can accurately lift prefabricated beams and plates to the designed position. During the lifting process, the angle and length of the boom and the position of the crane can be adjusted to ensure accurate installation of components and improve construction efficiency and quality.

3. Lifting of construction equipment

Installation of tower crane components: In high-rise building construction, tower cranes are important vertical transportation equipment. Truck cranes can be used to lift various components of tower cranes, such as tower sections and booms. In the installation and disassembly process of tower cranes, truck cranes play an indispensable role. Their flexible maneuverability can complete lifting operations in the narrow space around tower cranes.

Lifting of other small construction equipment: When small construction equipment such as mixers and electric welders are transferred between different floors, truck cranes can also quickly and safely complete the lifting to ensure the continuity of construction.

4. Safety assurance and operation points

Site requirements: When using a truck crane, it is necessary to ensure that the construction site is solid and flat to ensure the stability of the crane. For soft ground, auxiliary measures such as laying steel plates may be required.

Operation specifications: Operators must strictly abide by the operating procedures and accurately calculate the weight and lifting radius of the heavy objects before lifting to prevent overloading of the crane. At the same time, they must maintain good communication and coordination with other personnel and equipment on the construction site to ensure the safety of the lifting process.
