Why choosing PLC synchronous lifting system?
To achieve the synchronous lifting requirement for large buildings, the semi-automatic hydraulic lifting systems were widely used in the past. But with increasing weight and volume of the large building, more complex structure, nonuniform loads, these require the more higher synchronous precision and more control points. That means the hydraulic lifting systems must reach the multi-point synchronous lifting with high precision, but how to achieve that has become a difficult problem. The feature of PLC synchronous hydraulic lifting system lies in it can achieve multi-point synchronous lifting with high precision.
System Features
- Variable frequency, pulse width speed adjusting closed loop control, high speed reaching, low speed lifting. The lifting speed can be controlled.
- Advanced Oil feeding with speed regulation, heavy load preferential declining hydraulic circuit.
- Not only keeping the precisely synchronous when lifting, the same as declining with load.
- Multi-point synchronous, and in this condition, except keeping the position synchronous, the load in every point can be adjusted.
- The points can be: 4, 8, 12, 16, 24, 40, 80 to infinite.
- Operation mode: button and touch screen combination or button and Industrial computer combination.
- The main console using industrial computer, concise interface easy operation. Strong stability makes it can be used to kinds of Industrial environment.
- Lifting data can be imported into the equipment database one time, for checking, printing, download.
- The system with function of “automatically being Zero position” through one button. No matter how complex of the foundation, all jacks can reach to the foundation at same time.
- Telecommunication bus connect with Central synchronization console and PLC stabilization of many pumps using. Inserting way, to achieve the purpose of passing Information.
- This system can work with the most of KIET standard hydraulic jacks together, the sing acting jacks and double acting jacks both can be chosen.
- Good quality, flexible configuration, high cost performance.
System Description
PLC multi-point synchronous hydraulic lifting system is consisted by 5 parts: hydraulic pump, PLC computer control system, hydraulic terminal, displacement and pressure detection and human-machine interface operation system. This system integrates the hydraulic lifting system, PLC signal processing, displacement detection, analysis of bridge structures, and construction technology as a whole advanced system. The core is that based on the analysis of bridge structures and conclusion of construction technology, according bridge features to design the PLC signal processing and hydraulic system. Inputting the displacement signals and outputting oil control information of hydraulic system. Using terminal cylinder groups to achieve the purpose of lifting bridge with safety and high efficiency. The precision error no more than ±0.5mm.
