KATTOR, based on its advanced technology in hydraulic equipment and many years’ experience in construction engineering, has researched and developed its Intelligent Synchronous Lifting System (SLS), which integrates computer controlling technology and unique performances of hydraulic equipment. This SLS system provides a more dependable, efficient and customized solution for those working conditions requiring lifting, lowering and leveling movements. 

Accurate control

SLS system capable of setting up, controlling and monitoring the pressure and displacement of each lifting point respectively;

Synchronous accuracy of less than 1mm can be ensured between all action points

Beam lowering has the same accuracy with lifting process.

Flexible adaptability

One module to control 2, 4, 6 lifting points, max. 99 modules in one PLC system

Additional oil tanks can be added on each modular unit to improve oil capacity

Compatible with both single and double acting cylinders

Synchronous lifting for bridges with long-distance, large-span and multiple piers, and other complicated projects

Easy operation

Quick connectors applied on PLC controlling system, hydraulic pumps and all related attachments;

Touch screen and intuitive human-machine interaction interface proffering easy and convenient operation

Safety and reliability

Automatically record, store and feedback of operation data, dynamically monitor and display the position of all lifting points.

System secured with warning and stopping functions when deviation happens

Project Name:Chengdu-Guiyang Passenger Railway Caiba Minjiang River Bridge

Location: Yibin City, Sichuan Province

Project profile:

Caiba Minjiang River Bridge is a double-track passenger-dedicated railway bridge, with a total length of 1.19km and designing speed of 250km/h. Bridge spans are composed by precast box girders (13 X 32m), continuous beams (48m+80m+48m), through type steel-truss beams (140+224+140), cast-in-situ box girders (2 X 32m). The steel truss beams is 16-32m in height, and 14m in width. Caiba Minjiang River Bridge is one of key projects of Chengdu to Guiyang Railway in Sichuan Province, also the biggest Steel Truss Bridge in Yibin. 

Challenge:

During bridge joining process, for the long and heavy continuous steel-truss beams (140 + 224 + 140), how to precisely control horizontal movement, linear adjustment and positioning is one of the most critical parts. 

Solution:

Kattor’s intelligent hydraulic equipments and synchronous controlling technology were adopted to make the steel truss girder segments move smoothly and accurately to designed position.

Meanwhile, Kattor 3D Adjustment System (3DAS) was successfully applied on deviation-correcting of the beams,  which has achieved precise adjustment and ensured each segment of the beam meet designed requirements. 

Applied products:

KATTOR Intelligent 3D Adjustment System (3DAS), Incremental Launching System (ILS), Synchronous Lifting System (SLS)
