Large Tonnage Bridge Tension Lifting Jack
Introduction of Synchronous lifting jack
The hydraulic synchronous lifting system is equipped with security measures such as anti-electromagnetic interference, misoperation locking, hydraulic pipeline pressure loss self-locking, clamper reverse movement self-locking, overload alarm, and other security measures to ensure a smooth, safe, and reliable construction process. Each lifting point of the system can automatically adjust the height difference during construction, which has the advantages of high synchronization accuracy, high construction efficiency, economical and practicality, etc.

Applicable fields of Synchronous lifting jack
According to the difference in the installation position of the hydraulic jack relative to the structure during use, the construction process can be divided into three methods: lifting, jacking, and climbing. The hydraulic synchronous lifting system is widely used in the vertical hoisting or lowering of large structural parts, such as the hoisting of steel box girders of bridges, the lowering of bridge piers and weirs, the hoisting or lowering of hanging baskets, the hoisting of chimney steel inner tubes in power plants or chemical plants, and the steam drums of power plants. And stator hoisting, gantry crane installation, aircraft maintenance garage, gymnasium, and other steel structures and other super high and super heavy large-scale structure hoisting, etc.
Features 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, and 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.
