The structure of slewing jib crane is a jib suspended on a bracket, which can be driven by a motor to move and rotate horizontally and vertically within a certain range for lifting and carrying heavy objects. The fabrication process is to determine the design scheme, fabricate the bracket, fabricate the jib, install the motor, install the control system, test and debug.
1、Determine the design scheme: Determine the design scheme of the top manufacturer slewing jib crane according to the use environment, weight of the lifting object, working range and other factors.
2、Make the bracket: make the bracket of jib crane according to the design scheme, which can be made of steel, aluminum alloy and other materials.
3、Make the arm frame: make the arm frame of the jib crane according to the design scheme, it can use the same material, or use the composite material and other lightweight materials.
4、Installation of motor: install the motor on the bracket and connect it with the arm frame to form a complete jib crane structure.
5、Installation of control system: install the electric control box, remote control and other control systems to ensure the normal work of the jib crane.
6、Testing and debugging: after the installation is completed, testing and debugging are carried out to ensure the safety and stability of the jib crane.
The above is the basic production process of slewing jib crane with electric hoist supplier, the specific production process also needs to be adjusted and modified according to the actual situation.
Mobile jib crane in the structure of thin-walled profiles and shaped steel, reduce the structure of the splicing weld, improve fatigue resistance. The use of a variety of new high-strength low-alloy steel materials, improve the load-bearing capacity, improve the stress conditions, reduce self-weight and increase the appearance of beautiful. Most of the bridge structure type of mobile jib crane adopts box-shaped four-beam structure, and the main beam and end beam adopt high-strength bolt connection, which is convenient for transportation and installation.
In order to reduce the weight, improve the carrying capacity, improve the processing and manufacturing conditions, increase the product yield, parts and components as far as possible to use welding instead of casting, such as the reducer shell, roll Jane, pulley, etc. are used in welded structures. Reducer gears are hardened to reduce weight, reduce volume, improve load-bearing capacity, increase service life. The application of hydraulic actuator disk brake is also increasing. In addition, the motor used in each organization are to high speed development, thus reducing the motor base number, reduce the weight and reduce the external dimensions, and can be equipped with brakes with small braking torque.
Mobile automated slewing jib crane manufacturer in the electronic control development performance, low cost, high reliability of the speed control system and electronic control system, the development of semi-automatic and fully automatic operation. The use of electromechanical instrumentation and liquid integration technology to improve performance and reliability, increase the mobile jib crane function. The control technology of fuzzy logic circuit is developed to find the best moment to start accelerating by using neural information and fuzzy technology, and the data of the actual operation of the experienced driver’s anti-swing are inputted into the system to realize the optimal control. The fuzzy control method can determine the control instructions for implementing automatic work, and digitize and quantify the fuzzy quantities that are subjective to people through fuzzy sets
