Complex combined action of forces with Enerpac - Synchronous Lifting System perfectly under control
Digital hydraulics helps to position railway bridge
Local conditions sometimes make it impossible to build a bridge on-site. In those cases the bridge must be built up on an adjacent site or bank and then be moved to the final position. This also happened in the Brussels Schaerbeke, where a steel railway bridge with a length of 140 metres and a weight of over 1600 tons had to be slid across a number of already existing tracks. Enerpac was asked to hydraulically monitor the movement and the forces that occurred during the movement with its digital ‘Synchronous Lifting System’ and to make corrections if necessary.

The new railway bridge in Brussels was built by order of the Belgian railways by Victor Buyck Steel Construction, a large internationally operating Belgian steel construction company. The bridge was supplied in parts and assembled on one side of the newly built railway viaduct. The bridge was ready to be moved to its place by the end of October. Because of the intensive use of the railways over which the bridge had to be placed and the fact that the railway traffic had to be stopped during the movement, the builder was given only 48 hours time to move the bridge to its proper place.

Complex combined action of forces

A steel construction may be called rigid and inflexible, but this is absolutely not true. Especially not in case of a steel railway bridge with a length of 140 metres and a weight of over 1600 tons. Enormous forces are developed during the movement. Under the influence of these forces the steel construction and in particular the superstructure are subject to high, changing tensions and will certainly bend.

In order to have the combined action of forces develop evenly during the movement of the railway bridge and to prevent these tensions from becoming too high, the occurring pulling and pushing forces had to be measured and reduced if required. Additionally, the vertical position of the bridge had to be monitored, of course.

Manual monitoring and correction of the movement is too inaccurate in these cases. Too much variation at the different points of support results in unacceptable tensions that may affect the construction. Besides, manual monitoring and correction takes very much time and the builders did not have much time. Therefore Enerpac was asked to guide the movement of the railway bridge with its ‘Synchronous Lifting System’ that had proven itself all over the world in the meantime.

Platform wagons and strand-jacks (cable-lift cylinders)

For the first phase of the movement a series of hydraulically controlled, multi-axle platform wagons (super transporters) were used on both sides beneath the bridge as rearmost support points. For the second phase – the wagons could only reach a certain point – use was made of a hydraulic pulling system with ‘Strand-Jacks’, cable strands that pull the bridge metre by metre over the remaining distance. Apart from that a hydraulic retracting and braking system was provided, because the railway bridge had to be launched under a downward slope with a level difference of 2 metres. Eight temporary steel pillars were built to support the viaduct parts during the movement. Each pillar had been provided with a so-called ‘draw beam’, a pivoting steel cross with heavy springs to compensate the force, the angular displacement and the bending of the lower beam of the bridge. Beneath each ‘draw beam’ two hydraulic cylinders were mounted. The primary function of these cylinders was to keep the construction at the correct height. In order to reduce the resistance as much as possible during the movement Teflon gliding plates were applied between the ‘draw beam’ and the lower beam. Additionally, a launching nose (beak) was provided on the front side of the bridge for a safer distribution of the forces and to limit the bends and tensions during the movement.

Forces under control

Victor Buyck Steel Construction accurately calculated the forces and tensions that could occur at each support point during the movement beforehand. In order to be able to control this complex combination of forces and to correct it if necessary, Enerpac installed a monitoring system especially built for this.
This system consisted of a total of 32 measuring points (28 of which were used) on an equal number of hydraulic cylinders, a central pomp unit with a pressure of 700 bar, plc-control and a computer system showing all movements and forces. Project leader J.P. Vrombaut of Victor Buyck Steel Construction was very satisfied during the implementation already. “Also thanks to Enerpac things are going much faster than we expected”, he said.

Both the hydraulics and the electronics of the system were designed and developed by a team of experts in the ‘Enerpac Centre of Excellence’ in Spain. Enerpac itself hired out the equipment to the client, in accordance with the policy pursued with respect to such large projects. The installation and implementation were taken care of by the so-called Hevilifts-team, experienced Enerpac experts from Great-Britain. The total project period – installation phase, test phase, implementation and completion - covered two weeks.

Synchronous Lifting System: Digital hydraulics

The integrated and automatic ‘Synchronous Lifting System’ of Enerpac is a combination of hydraulics with digital monitoring and control. No matter whether a bridge or a large building is concerned, this system offers an extremely effective method for both vertical and horizontal movement and positioning. The total system is built in such a way, that the different measuring points and cylinders are stable and do not influence each other and it checks the measuring way and force. For this the control system receives electronic signals from the movement sensors and the pressure in the cylinders is also electronically transmitted through sensors. The computer continuously calculates the force on each cylinder using pressure sensors. The system checks the position and movements of the individual cylinders and controls pomp and valves if necessary to keep the forces at the correct value. In this way each point of the object is moved automatically and fully synchronically and positioned with millimetre accuracy. When the force is outside a set value, the pressure is ‘adjusted’. Here the speed of the computer is used to quickly send short pulses to the hydraulic valves. The result of this is that the individual cylinder movements can be many times smaller than with manual operation. At the moment that a cylinder movement is outside the tolerance, a warning signal is sent and the entire movement is stopped manually or automatically.
Cartagena Port Expansion - Integrated Hydraulics shapes World-Record Size Concrete Blocks
The Cartagena Port, in the province of Murcia in the South of Spain is expending its capacity and additional jetties are being built to further protect the harbor from the sea.

The construction process for the jetties is based on that of concrete blocks. Not the average size concrete block, but the largest blocks ever built worldwide, 70 x35 x 35 meters. NECSO, main contractor for this project, purpose built a large catamaran style concrete block builder for the project. The “KUGIRA” is capable of building a super-size block every 7 days. On one of the existing piers of the Cartagena port a sizable concrete factory serves the enormous catamaran in the harbor that carries the actual concrete block builder.

The “KUGIRA”, uses a sophisticated hydraulic integrated system to lift and lower the so-called construction – umbrella that holds the block construction formers. On both sides of the catamaran 15 sets of stage-lifting hydraulic units operated by 3 high-flow power sources and controlled by a synchronized PLC system operate the 35 meters wide and 70 meters long umbrella. The umbrella is shaped to form the blocks including the internal cells for stiffness and valves for the control during the sinking process.

Controlled Movement

Due to the size of the concrete block and thus the umbrella, the risk of twisting and therefore locking the umbrella between both catamaran walls is a serious thread to the process. For that reason a fully PLC controlled synchronized hydraulic integrated system was designed by ENERPAC’s European Construction Center of Excellence. Technical director Jesus Gonzalez based the synchronized design upon a hydraulic climbing stage lifting technology.

Along both sides of the catamaran huge but lightweight constructions hold the climbing stage lifting steel notched plates, while the climbing stage lifting hydraulic units are fastened to the umbrella deck. As mentioned before, 15 units along each side of the umbrella deck. Each unit exists of an advanced ENERPAC hydraulic system including stroke– and and proximity–sensoring technology.

Climbing Units

All 30 climbing units comprise two long stroke hydraulic double acting cylinders of 70 tons capacity and two double acting hydraulic locking cylinders of 20 tons capacity. The long stroke cylinders, used for the actual lifting and lowering process, include a magnetic stroke sensoring system, which communicates the plunger’s position via a local manifold and valving unit to the central PLC-system. The locking cylinders also include stroke sensors that signal their position to the PLC-system where all data is processed and communicated back to the pumps and 2/2-way valves that control all cylinders (120 in total) in all 30 climbing units. The locking cylinders are used to fix the climbing units during the climbing process.

The main PLC-system is operated via a touch screen with a graphical user interface, continuously showing the actual stage of the process, including all parameters. Overall lifting and lowing accuracy of the entire system is 0,01 mm.

Flexible Design

The size of the port project and future upcoming projects of this type of port and jetty building was the main reason for NECSO to design the ship with maximum flexibility. Not only concrete blocks of 35 x 35 x 70 meters can be built, but also several other sizes. One option is to build 2 blocks simultaneously of 35 x 35 x 34 meter each, whilst another configuration allows the construction of one block of 35 x 35 x 34 and two blocks of 35 x 35 x 16 meter simultaneously. Consequently the ENERPAC hydraulic system is designed to deal with all these different configurations.
 
Buildings and stadiums & Large equipment repair
No two projects are the same. However, they all require innovative solutions, reliable equipment, and precise execution. Here are some examples of how Enerpac has helped in the successful controlled movement of large, well-known buildings and stadiums.

The controlled lifting of large equipment weighing several thousand tons leaves no room for error. Enerpac’s track record of successful heavy equipment projects helps to ensure worry-free and reliable lift execution.
 
Beijing’s National and Olympic Stadium
September 17, 2006, after two years of construction, the main venue for the 2008 Beijing Olympic Games came to a final and most important part of the construction of its steel structure: the dismantling of the temporary support towers.

When presenting their stadium design to the Chinese jury, the Swiss architects Herzog & Meuron used the analogy of a bird’s nest. Everyone loved the idea of a bird’s nest and so they won. Perhaps because of the culinary association; in China, a bird’s nest is very expensive and believed to be extremely healthy, something you eat on very special occasions.
During construction, the crisscrossed interwoven steel roof construction of the bird’s nest roof was supported by 78 temporary steel columns. For additional stability, the huge ‘twigs’ were welded onto the supports. After completion of the bird’s nets construction the ‘twigs’ had to be cut off the support piers, before dismantling of the piers could start.
In most western countries, cranes would have been hired to do the lifting job while welders would cut off the welds off the 78 supports laid during construction. However, due to the extreme high cost of hiring a number of 800-ton cranes for several days in China, a smarter and less expensive solution needed to be found. Key pre-requisites to the entire cutting-operation were safety, control, stability and cost. Enerpac, known from many complex hydraulic applications around the globe and in the Chinese market especially for their hydraulic solutions for moving roofs (NanTong stadium) and moving structures (Shanghai concert hall) was consulted.

Basically the disconnecting and dismantling process of the temporary supports comes down to synchronically and fully controlled lifting the structure of its supports, cutting the welds, followed by controlled and synchronized stage-lowering to allow the removal of the 50mm think leveling plates that were used during construction. Computer-controlled hydraulics is the perfect match for jobs like this, and Enerpac was granted the contract to perform the stage lifting and lowering of the roof.

The entire configuration including the central computer, satellite computer-controllers, 156 double-acting high-pressure hydraulic cylinders and 55 electronically controlled hydraulic power units was specified and custom designed by ENERPAC. For added safety, control and accuracy, multi-functional valves, load sensors, stroke sensors, shift detection and a digital feedback system were integrated.

The design of the bird’s nest is based on three construction circles; an outer circle, a central circle and an inner circle. Each circle has a specific number of supporting piers, varying from 24 for the outer and central circles and 30 for the inner circle. For load, control and accuracy reasons the 78 support points including their hydraulic systems are divided into 10 regions, each of which with its own satellite controller. For the actual stage lifting and lowering process each support pier is equipped with two 150-ton double-acting cylinders. At the central computer all load and stroke data are pre-programmed for a fully controlled lifting and lowering process. During the stage lowering process the bird’s nest is alternatively supported by the hydraulic cylinders and the leveling plates on the temporary supports.

After successful disconnecting the 45.000 ton steel structure from its temporary support piers, last year November, the bird’s nest stood on its own “feet” for the first time.

Maximium safety during maintenance of 5000 tons dredger at Loy Yang
One of the world’s most advanced heavy lifting systems has been deployed in Australia to maximise safety and precision during maintenance of a huge dredger at the largest coal mine in the Southern Hemisphere.

The PLC controlled Enerpac Synchronous Lifting system was used by Hydraulic and Pneumatic Pty Ltd of Morwell in conjunction with Plant Performance Group Pty Ltd to enhance precision and safety while monitoring the 2200-ton load’s centre of gravity during the lift on Dredger 16 at Loy Yang Power. Dredger 16 is longer than the MCG (200 metres), as high as a 16-storey building (55 metres) and has a slew ring bearing 15,2 metres in diameter containing 177 balls of 200mm diameter each weighing 32kg. It weighs a total of more than 5.000 tons and can remove 60.000 tons of overburden a day. The successful lifting and balancing of its huge superstructure illustrates the versatility of the Synchronous Lift system for major industrial and civil engineering tasks, including manufactured structures, buildings, bridges, oil platforms, ships, turbines, generators, mills, mining equipment and heavy but delicate computerised/electrical equipment, says Enerpac.

The Synchronous Lifting technology chosen for the task of hoisting Dredger 16’s superstructure to inspect and refurbish the giant machine’s slewing ball race uses digital synchronisation control accurate to within a 1 millimetre between leading and lagging lifting points. Accuracies are available down to 0,1mm.
The delicate job of carrying out the lift with maximum safety and minimum downtime was carried out with the assistance of a team led by Shift Supervisor Mr David Little of Silcar, which is an asset manager and provider of maintenance services for technically complex assets.

The task involved two-stage lifting and lowering over 250mm, with the Enerpac Synchronous system governing six 630 ton hydraulic cylinders used in pairs at three lift points. Project Manager Mr Tom Lamin of Plant Performance Engineering acting for Loy Yang Power, said the lift proceeded smoothly, with the hoisting being undertaken on May 7 and lowering on May 13. The huge task was facilitated by the accuracy and fluency of the synchronous lift operation, and the real-time centre of gravity display.

Hydraulic and Pneumatic Sales Manager Mr Robert Lewis said the job required thorough planning to maximise safety and minimise downtime for a client operating the largest open cut coal mine in the southern hemisphere. Loy Yang operates 24 hours a day mining more than 30 million tonnes a year of the brown coal that provides more than half of the State’s electricity needs.

“Everything is on a large scale – the slewing ring is huge and the superstructure above it is bigger than many ships’, so the job had to be done with incredible care and precision to meet the client’s top world class standards of safety.”

The Synchronous Lifting system used by Hydraulics and Pneumatic was an eight-point model that can be used with multiple cylinders ranging from 10-1000 tonnes capacity each. Larger models feature up to 64 control points. The hydraulic technology involved is the same type chosen to maximise safety on some of the world’s most precise lifts, ranging from Ariane rocket launch pads and oil drilling platforms in Europe’s North Sea, to splitting coal shovels and building and weighing wharves and infrastructure in Australia.

“In addition to being precise and giving us the centre-of-gravity accuracy we needed, the technology had to be able to function flawlessly in a harsh environment, with coal dust blowing around the power unit. We needed to be assured – and this turned out to be exactly the case – that the technology package developed in conjunction with Enerpac would operate in total safety and reliability.”

Controlled hydraulic movement

Enerpac Engineer Ray Paasila said safety was built into the synchronous system – “During lifting in automatic mode, the software meticulously follows each lifting point and each cylinder. The software also constantly monitors which lifting points are in the highest and lowest positions and whether these are still within the set tolerances. If a correction has to be applied, the 2/2 movement valve opens briefly and the relevant (lowest) cylinder receives a short hydraulic impulse, instantly followed by a new reading. This correction process is so fast that the relays that control the valves give the effect of perfect switches.

“The course of the lifting process can be followed on screen (per lifting point). The software also contains an extra control function, by which the system can temporarily be stopped and manually corrected. Emergency stops also built into the system. If something goes wrong, the system will stop automatically and block all points of support.

“In addition to time saving and the exceptionally accurate and virtually stress-free movement of an object, the advantages of Synchronous Lifting include its ability to record and document the entire repositioning process. All the values are stored in the control systems memory for later use. With satisfactory progression of the procedure, this provides both the contractor and the client with a clear guarantee that excessively high stresses have not occurred.”

Enerpac synchronous lifting technology has been used in Australia for integrated solutions involving ultra-precision civil, mechanical, industrial and maintenance engineering tasks, including the splitting of a dragline at Curragh coal for maintenance and during vital stages of the ongoing .2 billion expansion of the Dalrymple Bay Coal Terminal near Mackay, where it was used to lift and weigh 80-tonne sections of wharf.

“In addition to time saving and the exceptionally accurate and virtually stress-free movement of an object, the advantages of Synchronous Lifting include its ability to record and document the entire repositioning process.

“All the values are stored in the control systems memory for later use. With satisfactory progression of the procedure, this provides both the contractor and the client with a clear guarantee that excessively high stresses have not occurred.”
