Intelligent Bridge Construction Machine Hydraulic Synchronous Lifting Jack

600t Hydraulic Strand Jack with Synchronous Lifting System

Introduction of Synchronous lifting jack

The hydraulic synchronous lifting system is mainly composed of the hydraulic pump station, lifting jack, and control system. It is a high-tech product integrating mechanical, electrical, hydraulic, and computer principles. Equipment for overall hoisting or lowering of high-altitude construction structural parts and overweight structural parts.

Technical Parameter of Synchronous lifting jack

Working Principle of Synchronous lifting jack

To integrate the prestressed anchor anchoring technology with the hydraulic jack technology, anchor the steel strand through the anchor, and then use the computer to centrally control the flow and oil pressure output of the hydraulic pump station.
The device drives the jack piston to extend and contract (displacement sensor device)and forces the steel strand and the component to rise, descend, and continuously translate to realize the overall synchronous lifting (translation) and lowering movement.

Advantages of Synchronous lifting jack

1. The lifting equipment is small in size, light in weight, large in carrying capacity, convenient and flexible in installation, especially suitable for lifting large-tonnage components in small spaces or indoors;
2. By expanding the combination of lifting equipment, the lifting weight, span, and area are not limited;
3. Using low-relaxation steel strands, as long as there are reasonable load-bearing lifting points, the lifting height is not limited;
4. The hoisting jack anchor has the self-locking property of reverse movement, which makes the hoisting process very safe, and the components can be reliably locked for a long time at any position during the hoisting process;
5. The equipment has a high degree of automation, convenient and flexible operation, and has various operation modes such as automatic operation, semi-automatic operation, single-point adjustment, and manual operation. The display has a liquid crystal display, and the touch screen display is very intuitive. And the control system is equipped with a self-correction protection program, even if it is misoperated, it will not cause a safety accident.
6. Using this equipment for construction, the construction period is short, the cost is low, and the economic benefit is good.

Process and Technology of Synchronous lifting jack
1. Scope of application
This technology is suitable for the overall lifting of steel mast antennas of TV towers and the overall lifting of grids, roofs, steel overpasses, and other components of large-scale public works such as gymnasiums, swimming pools, hangars, theaters, waiting for (ship) rooms, etc. The overall lifting of the crane's main beam and the slippage of the steel roof truss (cover) of the main building of the airport terminal.
2. Methods and Features
Lifting method
At present, the methods of "steel strand suspension load-bearing, hydraulic lifting jack cluster, and computer control synchronization" are mostly adopted. There are two methods as follows:
①Pull-up type (that is, lifting type): The hydraulic lifting jack is set on the permanent column of the load-bearing structure, the upper end of the suspended steel strand is fixed (anchored) with the hydraulic lifting jack through the core, and the lower end and the lifting member are anchored and anchored with special tools. Connected together, like "lifting water from the good platform", the hydraulic lifting jack holds the steel strand and lifts it up, thereby lifting the component to the installation height. This scheme is the pull-up lift type.
②Climbing type (climbing pole type): the upper end of the suspended steel strand is fixed on the permanent structure (or the foundation or the temporary reinforcement facility connected with the permanent object), and the hydraulic lifting jack is set at the lower end of the steel strand (hydraulic lifting jack The anchor is connected to the component), like a "monkey climbing pole", the hydraulic lifting jack holds the steel strand and climbs up, thereby lifting the component to the installation height.
The climbing type is most suitable for the lifting of upright members with high lifting height, general projection area and relatively light weight, such as steel mast antennas of TV towers.
