A synchronized lifting system is a technological innovation that has revolutionized heavy lifting across various industries. This system comprises several hydraulic jacks that work in tandem to raise and lower heavy objects with actual effectiveness. The synchronized lifting system is becoming famous due to its ability to complete complex lifting tasks previously unattainable with traditional lifting equipment. In the following article, we’ll examine the details of the synchronized lifting system and how it operates.
What exactly is a synchronized lift system?
A computer system that is designed to allow controlled hydraulic motion is a lifting system that is synchronized. The extension and pressure of cylinders are transmitted to an electronic control system within this system that is electronically controlled.
The control system will automatically open and close the valves for directional control as required to ensure that the load level is within a specified and exact tolerance. The system can correct minor variations in the pump output or the cylinder’s size. A synchronous lifting and lowering system is commonly utilized for bridge lifting or shifting, lifting and lowering large equipment, leveling structures, and structural testing.
Individual cylinders can be operated by hand to set up the cylinders in addition to fully automated lifting and lower. Monitoring and data recording are displayed on a touch screen, and all security features are included.
The Synchronous Lifting System allows synchronous lifting and jacking to be completely computerized. This system is geared towards precision, tolerating as close as 0.04 mm between the leading and the lagging cylinders. As many as 24 lifting points can be controlled.
Data can be recorded and stored, and the system could be operated with regular double-acting cylinders or single-acting ones. To position and weigh loads, strokes and load-controlled movement are employed. To ensure maximum security, alarms for stroke and load are in place. Hydraulic pumps and controls are integrated with up to 10,000 PSI.
Synchronous Lifting Technical Requirements
The actual task of lifting and taking down the old bridge before erecting the new bridge is the background for this paper. The need for precise monitoring of the lifting equipment is enormous, requiring precise control of the speed and displacement and ensuring that the multipoint synchronization failures remain within a specific range.
The force study of the bridge is carried out with the aid of finite element software. Suppose the displacement deviation in the lifting process of a bridge demolished in the past is lower than millimeters. In that case, the bridge structure will likely fail to crack in principle and meet the requirement for demolition.
Since the bridge of the future has been designed as an integrated steel construction, the deformation limit is essential when put together as a whole. Also, it can meet the requirements for construction and installation. It means that the deviation in displacement must be controlled to a limit of 5 millimeters.
It poses substantial technical challenges when creating an electrohydraulic control device. When the deviation of displacement reaches or exceeds the allowed amount, it will issue an alarm and close the hydraulic system to protect the bridge’s structure, examine and identify the root of the issue and then resume lifting when all issues have been addressed.
