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.
