A 3D model of a tower crane is a digital representation of the real-world construction equipment. The model captures the key components of a tower crane, including the base, tower, jib, and operator’s cab. The base is typically a solid, heavy structure that provides stability. The tower, or mast, is a vertical steel structure that reaches impressive heights. The jib, or working arm, extends horizontally from the tower and is where the lifting gear is located. The operator’s cab is where the crane operator controls the machinery.

The 3D model can be designed with a high level of detail to accurately represent the mechanical complexity of a tower crane. It can be used in various applications such as construction planning, safety training, and virtual reality simulations.

A 3D model of a safety helmet, on the other hand, represents personal protective equipment used in many industries, including construction. The model captures the helmet’s hard shell designed to resist impact and a suspension system inside the helmet to provide additional shock absorption. Some models may include additional features such as visors or earmuffs.

The 3D model can be used in safety demonstrations, product design, or virtual reality applications to provide an immersive experience in workplace safety training.
