Preface:

In today's society, where children's education is increasingly valued, scientific enlightenment education has gradually become an important topic in the field of education, which is pursued and explored.
More and more teachers and parents are beginning to focus on cultivating children's scientific literacy from an early age, so that children can develop good personalities from the very beginning.
Behavior habits. Parent-child interactive crafts can improve the quality of parent-child companionship, improve the relationship between parents and children, and the time we spend with our children,
Without mobile phones, iPads, or televisions, there is only joy, interaction, and communication. This can cultivate the ability to solve problems by oneself.
Children should first see and experience the solution themselves, because this is how parents, teachers, and others solve problems when they are doing crafts. This can help develop children's problem-solving skills.
Children's imagination, in the world of children, cars can fly in the sky, the sun can be green... Playing with DIY crafts can cultivate
The children's ability to use tools has allowed their little hands to fully engage in activities. Brushes, paints, scissors, hot glue guns,
Glue....., all kinds of tools are willing to try, and to a certain extent, they are developing different skills. Improving children's self-confidence in handcrafting.
During the process, we tried everything possible and experienced many failures, but we always succeeded, which to some extent strengthened his self-confidence. Cultivating.
When a child is exploring various tools and crafts, he is very focused. If there is no external disturbance, he can continue to explore.

The purpose of the experiment: To enable children to understand more scientific knowledge and their own ability to practice through the fun of playing games.

Principle Application: This small model of a tower crane is a simulation of a real industrial machine used in construction scenarios. Tower cranes, also known as crane towers, are a type of crane used in construction.
Originated in Western Europe. The jib crane is mounted on the top of the tall tower and rotates. It has a large working space and is mainly used in the construction of building materials.
Direct and horizontal transportation and the installation of building components. It is composed of three parts: the metal structure, the working mechanism, and the electrical system. The metal structure includes the tower body.
The work mechanism consists of four parts: hoisting, swinging, rotation, and movement. The electrical system includes motors, controllers, and distribution cabinets.
Connecting lines, signal and lighting devices, etc.

Experimental Cognition: Little Science Facts: What is a Tower Crane?
A tower crane is a rotating crane with an operating arm mounted at the top of a tall tower. It has a large working range and is mainly used for the vertical transportation of materials and the installation of components in multi-story and high-rise construction. It consists of three main parts: a metal structure, a working mechanism, and an electrical system. The metal structure includes the tower, the boom, the jib, the attachment poles, etc. The working mechanism includes four parts: hoisting, luffing, rotation, and traveling. The electrical system includes motors, controllers, distribution boxes, connecting lines, signaling, and lighting devices.

Knowledge Expansion: Tower cranes are divided into two categories: top-rotating and bottom-rotating.
1. Top-rotating tower crane: The tower does not rotate, and the jib, balance arm, etc. above the rotating support rotate around the tower centerline through the rotating mechanism. It is divided into running, fixed, attached, and internal climbing types according to the requirements. Running tower cranes can move along the track, with a large working range and wide application, suitable for multi-story construction; if the crane base is fixed on the track or the tower body is directly fixed on the foundation, it becomes a fixed tower crane with a longer jib; if the fixed tower crane is connected to the building every certain height with attachment rods, it is an attached tower crane, which uses the tower heightening device to make the upper rotating part of the crane can be increased with the building height, used in high-rise construction; if the crane is installed in the elevator shaft or other holes or connected holes, it is called an internal climbing tower crane, which uses hydraulic cylinders to make the crane climb up the well along with the construction process, it saves some tower bodies, has a large service range, and does not occupy the construction site, but it has certain requirements for the structure of the building.
Two:
The under-rotation type hoisting crane: The rotating support is installed between the base and the turntable, and all other working mechanisms are arranged on the turntable to rotate together. In addition to track-type, there are track-type and tire-type with track-type and tire-type undercarriages as walking devices. It has a low center of gravity of the whole machine, can be disassembled and transferred as a whole, is light and flexible, and has a wide range of applications, suitable for multi-story construction.

Knowledge Extension: Are you having trouble with the production? Check if the following issues have occurred!
After the tower crane is installed, it cannot lift.
1. Check if the wiring is properly connected.
Check if the battery is low on charge and recommend replacing it with a new one.
3. Check if the rope is placed in the belt wheel groove.
4. Check if all fixed rings are spaced 1mm apart and are not too tight.
5. Check if the gears mesh correctly.

Safety Warning:

All the accessories in this product are specially designed for student experiments. Please use them under the supervision and guidance of your teacher and parents to ensure safety!
All products are non-edible! Not suitable for use by children under three years of age. Do not use near open flames. Before assembling any products that use batteries, please check the instructions carefully.
Check if the circuit is in good condition, if all the components are complete, and if all contacts are in good condition. The + on the battery is the positive terminal, and the - is the negative terminal.
Negative pole, during the assembly process, be careful not to get glue on your eyes or skin if it is used.
