Cranes, gantry cranes are industrial lifting equipment, capable of moving heavy objects with very large loads. So what is the manufacturing process of these devices to ensure quality and meet job requirements? Let's find out in the article below!
Cranes and gantry cranes are made of steel structures and manufactured and installed according to technical drawings. The manufacturing process of cranes and gantry cranes includes 3 stages: design, manufacture and installation.
Manufacturing process of cranes, gantry cranes
1. Design of cranes and gantry cranes
Cranes and gantry cranes are designed based on the needs of use and the premises of the workshop using this equipment.
The design is sketched for the investor, after agreement, the design is completed. All design drawings are verified, ensuring quality and safety, along with static and dynamic load capacity according to usage requirements.
Requirements with design drawings are to ensure accuracy, complete dimensions, number and number of components.
2. Manufacture of cranes and gantry cranes
The manufacturing stage of cranes and gantry cranes is done based on design drawings and must absolutely comply with the drawings. The manufacturing process must always be strictly supervised and checked to ensure the correct implementation of the technique and drawings.
The details on the crane, the gantry are linked together through welds. Therefore, to ensure the certainty of these connections, visual inspection, ultrasound or magnetic testing are required to ensure the connection between the two steel plates.
Use a straightening machine to ensure that the structure is not warped, according to technical requirements.
Cleaning: The characteristics of cranes and gantry cranes are made of steel, so it is inevitable that dirt will stick and lead to rust. Directly affects the life of the device. To overcome this phenomenon, it is necessary to use equipment such as iron brush, sandblasting or ball blasting to clean the layer of dirt before spraying.
Spray painting: this is the final stage in the production of gantry cranes and cranes. Components are sprayed with 3 layers in sequence: anti-rust paint and 2 layers of color paint. To ensure the best service life of steel, the coating thickness should not be lower than 80um.
3. Construction and installation of cranes and gantry cranes
After the structure is completed, it is inspected and transported to the construction site to prepare for construction work.
During the construction and installation of the crane, the gantry crane needs to comply with the principles of safety assurance and the technical order of installation.
After completing the installation of the crane, the crane needs to check the bolts again, tighten them to ensure safety and certainty.
To ensure the safe operation of this equipment system, it is necessary to conduct no-load test run and check carefully before putting into operation with load.
Warning: If your facility is not a unit specializing in the production and installation of crane equipment, it is absolutely not advisable to make this equipment yourself for use, it will be very dangerous if you deliberately make the equipment yourself. this.
Above is the basic content of the 3 stages of crane and gantry manufacturing that we want to send to you for reference. Hope this information is useful for your work. If you need more advice on lifting equipment, please contact us for the most detailed answer.
