Synchronous bridge lifting systems have become the standard for complex lifting operations due to their ability to provide precise control and stability. They are used in many industries, including construction, prijevoz, i teške strojarije. This transition sets up the next section, which will explore what synchronous jacking actually is and how it operates.
What Is Synchronous Jacking?
Synchronous jacking refers to the process of lifting a bridge using multiple hydraulic jacks that move in unison to ensure even load distribution. Unlike traditional lifting methods, which may rely on manual control or simple hydraulic systems, synchronous jacking uses advanced technology to coordinate all lifting points simultaneously.
This system is particularly useful when lifting large, heavy structures that require delicate handling. The movement of each jack is carefully monitored and adjusted to maintain uniformity during the lifting process. This ensures that the bridge is lifted safely and without distortion, maintaining its structural integrity throughout the operation.

Synchronous jacking is not a new concept, but modern advancements have made it more reliable and efficient. The system relies on hydraulic jacks that are interconnected through a central control unit. Each jack receives the same pressure level, ensuring that they extend and retract at the same rate. This uniformity is crucial for structures like bridges, which can be hundreds of meters long and weigh thousands of tons.
The key to effective synchronous jacking is the synchronization of all lifting points. If one jack moves faster or slower than the others, može uzrokovati naginjanje ili pomicanje mosta, što može biti opasno. Da bi se ovo spriječilo, sustav koristi senzore tlaka i hidrauličke krugove koji pomažu u održavanju ravnoteže. Ovi senzori otkrivaju bilo kakvu neravnotežu u sustavu i automatski prilagođavaju tlak kako bi osigurali stabilnost podizanja.
Sinkrono podizanje također je vrlo prilagodljivo. Može se koristiti za razne vrste mostova, uključujući čelik, betonski, i modularne strukture. Ova fleksibilnost ga čini popularnim izborom i za novogradnju i za naknadno opremanje postojećih mostova. Kod LONGLOOD hidrauličkih alata, nudimo niz rješenja za sinkronu dizalicu koja su prilagođena potrebama različitih projekata. Naši sustavi osiguravaju da proces podizanja bude što glatkiji i precizniji.
Što je PLC kontrolirana tehnologija dizanja?
PLC (Programabilni logički kontroler) tehnologija kontroliranog podizanja ključna je komponenta modernih sinkronih sustava za podizanje mostova. It enables precise and automated control of the lifting process, making it highly efficient and safe. PLC systems are designed to monitor and regulate the operation of hydraulic jacks in real time.
The PLC acts as the central brain of the system, receiving input from pressure sensors and sending control signals to the jacks. This allows the system to adjust the lifting force and timing automatically, ensuring that the bridge moves smoothly and without any sudden shifts or stops. The use of PLC technology has revolutionized the way bridges are lifted, offering greater accuracy and control than older methods.

PLC controlled lifting technology combines automation with real-time monitoring to ensure a smooth and safe lifting process. Unlike manual or semi-automated systems, PLC controls allow for precise adjustments at each lifting point. This is achieved through a network of sensors that continuously monitor the pressure and position of the jacks. If any deviation is detected, the PLC can respond instantly, adjusting the system to maintain balance.
The main advantage of PLC controlled systems is their ability to handle complex lifting sequences. Each jack is connected to the PLC, which can program different lifting stages based on the project’s requirements. This includes adjusting the speed, sila, and timing of the jacks to match the specific needs of the bridge being lifted. The technology also allows for remote monitoring and control, which is particularly useful in large-scale projects where on-site visibility may be limited.
In addition to control, PLC systems offer data logging and diagnostics. This means that operators can track the performance of each jack and receive alerts if any part of the system is not operating correctly. These features help ensure that the lifting process is not only efficient but also reliable. Kod LONGLOOD hidrauličkih alata, our PLC controlled systems are designed for maximum performance, with features that allow for precise control, real-time monitoring, and data tracking. This ensures that every bridge lift is completed with the highest level of safety and precision.
What Are the Benefits of Multi-Point Synchronization?
Multi-point synchronization is a feature of synchronous bridge lifting systems that ensures even lifting across all designated points. This provides several benefits, including increased safety, improved efficiency, and reduced risk of structural damage.
By distributing the load across multiple points, the system prevents any single jack from bearing too much weight. This leads to better stability and a more predictable lifting process. Multi-point synchronization also allows for precise control of the bridge’s movement, making it easier to adjust the position as needed. Dodatno, this system can reduce the number of jacks required, saving time and money on equipment and labor.

One of the most significant benefits of multi-point synchronization is enhanced safety. When a bridge is lifted, even minor imbalances can lead to serious consequences. Multi-point systems ensure that the load is evenly distributed, reducing the risk of tilt, wobble, or structural failure. Sinkronizirano kretanje svih dizalica znači da most ostaje stabilan tijekom cijelog procesa, minimiziranje mogućnosti nesreća.
Još jedna prednost je poboljšana učinkovitost. Sustavi s više točaka mogu podići velike i teške strukture s manje dizalica, što smanjuje ukupne troškove opreme i rada. Također omogućuju brže operacije dizanja jer se sve točke pomiču koordinirano, eliminirajući potrebu za ručnim podešavanjem ili odgodama. To čini proces jednostavnijim, posebno za složene ili vremenski osjetljive projekte.
Sustav također omogućuje veću preciznost pri dizanju. Sinkronizacija u više točaka osigurava da svaki dio mosta bude podignut za isti iznos, održavanje njegove cjelovitosti i sprječavanje neravnomjernog naprezanja. This is particularly beneficial when lifting bridges that are long or have irregular shapes, as it helps maintain their structural alignment. Kod LONGLOOD hidrauličkih alata, we design our synchronous lifting systems to deliver accurate and stable results, što ih čini idealnima za širok raspon primjena.
What Are the Common Engineering Applications of Synchronous Bridge Lifting?
Synchronous bridge lifting systems are used in a variety of engineering applications, from construction to maintenance. These systems are particularly useful in projects that require precision, stabilnost, and controlled movement. One of the most common applications is in the relocation of existing bridges. This is often done to restore or upgrade the structure without disrupting traffic or surrounding infrastructure.
Another application is in bridge maintenance and inspections. Synchronous lifting allows engineers to access hard-to-reach areas of the bridge without compromising its stability. It is also used in the installation of new bridge components, such as support structures or girders, by lifting the existing bridge to create space for these additions. Dodatno, these systems are employed in the construction of new bridges, where they help lift and position heavy sections with minimal risk.

In construction, synchronous bridge lifting systems are used to raise and position bridge sections during assembly. This is especially important when building large-scale infrastructure, such as viaducts or overpasses. The system ensures that each section is lifted evenly, preventing structural misalignment or damage. In such scenarios, our synchronous lifting systems provide the precision and control needed for safe construction.
For maintenance tasks, synchronous lifting systems are invaluable. They allow engineers to lift a bridge just enough to access critical components, such as joints, ležajevi, or support structures, without causing any disruption to the surrounding area. This is crucial in urban environments where traffic cannot be blocked for extended periods. By using our synchronous lifting solutions, maintenance crews can work efficiently while keeping the structure safe and stable.
One of the most critical applications is the relocation of bridges. When a bridge needs to be moved, such as to make way for new infrastructure or to repair a damaged section, synchronous jacking allows for controlled and safe displacement. The system ensures that the bridge is lifted without twisting or bending, preserving its structural integrity. This is especially important in historical or heritage bridges that must be moved with great care.
Na kraju, these systems are used in the installation of new bridge components, such as beams, nosači, or support structures. During these installations, the system allows for accurate positioning of the components, ensuring that they align correctly with the existing structure. The use of synchronized lifting guarantees that the installation is done with minimal risk and maximum efficiency.
