Introduction of Synchronous lifting jack

Synchronous lifting jack is a new type of large-scale component lifting equipment, which is mainly composed of a lifting jack, hydraulic pump station, and control system. The principle is to integrate the prestressed anchorage technology with the hydraulic jack technology, anchor the steel strand through the anchorage, and then use the computer to centrally control the flow and oil pressure output by the hydraulic pump station, drive the piston of the lifting jack to extend and retract, and drive the steel wire. The stranded wire and components are lifted and lowered to achieve the overall synchronous lifting and lowering of large components.

Working Principle of Synchronous lifting jack

The Lifting Hydraulic Strand Jack working principle is 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.

Applicable fields of Synchronous lifting jack

This technology is suitable for the steel tower mast of the antenna and the gym, swimming pool, hangar, theatres, waiting room (the ship), and other large utility of network frame, roof and steel bridge structures, and large gantry crane girder of the ascent of the whole as well as the main building of the airport terminal of the ascent of the whole steel roof truss (cover) slip.

Performance characteristics of Synchronous lifting jack

• Principle: large steel structure hoisting, large bridge erecting, large ocean platform positioning.

• Small lifting equipment, lightweight, large carrying capacity, easy installation and flexible, especially suitable for small spaces or indoor large tonnage components to enhance;

• Increase the weight, span, and area without restriction by expanding the combination of equipment;

• The use of a low relaxation strand, as long as a reasonable load lifting point, lift height is not restricted;

• The lifting jack has self-locking properties of reverse movement to make the lifting process very safe and the components can be locked reliably in any position during the lifting process;

• High degree of automation equipment, easy to operate and flexible, with automatic operation, semi-automatic operation, single-point adjustment, manual operation, and other operations. The display has a liquid crystal display, touch screen display is very intuitive. And the control system is equipped with self-correcting protection program, even if the misuse will not cause security incidents.

• Construction with this equipment, short construction period, low cost, good economic returns.

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 lightweight, such as steel mast antennas of TV towers.

Bridge tensioning equipment is our primary research and development project, from R & D to manufacturing and installation, we strictly control every link to provide customers with high-quality products and active after-sales service.

Late autumn yellow, can also be customized according to personal preferences. Note: The specific color of the actual production batches shall prevail! The wooden package can also be customized according to individual needs packaging.
