A synchronized lifting system is an electrical technology that allows for controlled hydraulic movement. In this electronically regulated system, the pressure and expansion of some cylinders are communicated back to the central computer control system. To maintain the load level within such a predefined and accurate tolerance, this control software automatically opens as well as closes direction control valves as needed. As a result, minor variations in pump output or cylinder size will be compensated for by the system. Bridge raising and repositioning, heavy machinery lifting and lowering, structure levelling, and structural testing are all prominent uses for a synchronized lifting system.

Individual cylinders, and also fully synchronized lifting and lowering, can be operated manually for setup purposes. On the touchscreen, monitoring as well as data logging are provided, and all safety features are included.

A Riverlake Hydraulic split flow pump, including the Hi-Force HSP family, provides a multipoint lifting solution on a superstructure with unequal load distribution. The pump raises the load by delivering approximately equal flow of oil to each output, which is sufficient for a wide range of applications. However, when there is an uneven load dispersion or the cylinder stroke needed is extremely long, tiny discrepancies in the lift are amplified, which may result in an unequal lift in some cases.

Whereas the HSP family of pumps features a control hand piece that allows for separate modifications to each cylinder as required throughout the rise, if higher accuracy is required, a synchronous lifting device may be the preferable option. Hi-network Force’s offers a variety of HSP split flow pumps, but synchronized lifting systems are custom-designed to match each application by the design as well as engineering team. Throughout the lifting and lowering phases, FPT’s synchronous lifting technology was used to lift a bridge with an accuracy of 1 mm. Routine and emergency repair of roads, motorways, bridges, viaducts, railways, including undergrounds are necessary in the sphere of road infrastructure as well as construction, necessitating the usage of lifting equipment. The Synchronous Lifting System fully automates synchronous lifting and jacking. With inaccuracies as tight as 0.04′′ between the leading but also lagging cylinders, this system promotes precision. The system can manage up to 24 lifting points, save and record data, and work with ordinary single and double-acting cylinders. Stroke combined load-controlled movement are employed for positioning as well as weighing. Load as well as stroke alarms are incorporated for maximum safety. To 10,000 psi, hydraulic pump plus controls are incorporated.

Technical Requirements for Synchronous Lifting

This paper is set against the backdrop of the real process of raising and dismantling the old bridge as well as installing the new bridge. The demand for precise lifting device control is high, necessitating precise control of lifting speed and displacement as well as ensuring that multipoint synchronization errors are kept within a safe range. The force study for the bridge is done with finite element software. The construction will not break in principle as well as will satisfy the demolition requirements if the displacement deviation throughout the work task of an antique bridge deconstruction is less than 5 mm.

The permissible deformation range is large when the new bridge is constructed as a whole, and it can meet installation as well as construction criteria because it is an integral steel structure. As a consequence, the movement deviation must be kept to less than 5 mm, providing significant technological problems in the design of an electro – hydraulic control system. Whenever the displacement variation reaches or exceeds the permitted quantity, the control system will sound an alarm immediately closed down the hydraulic system that protects the bridge body. The control system will then investigate and discover the cause before resuming lifting operations.
