Introduction of Synchronous lifting jack

The synchronous lifting hydraulic system is computer-controlled overall lifting and lowering. The technology adopts flexible steel strand load-bearing, lifting steel strand hydraulic jack clusters, computer control, and hydraulic synchronous lifting principles. Combined with modern construction technology, it realizes large tonnage, large span, and large area. The super-large components are lifted and lowered synchronously at high altitudes. The flexible steel strand is used for load bearing, the lifting height is not limited, the self-locking property of the anchor is improved, and any position can be locked reliably for a long time.

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, 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.

The key process technology of Synchronous lifting jack
①Determination of the scope and form of the overall improvement:
Scope, the determination of the scope must consider the stability of the load-bearing structure (permanent and temporary structure) and the stability of the component itself. Therefore, before the scope is determined, it must be carefully negotiated with the design unit and the civil engineering unit to obtain a consensus. Then formulate and implement corresponding measures.
Form, the principle of form selection is to try to reduce the height of the supporting working column to ensure the stability of the working column; the second is to ensure the stability of the component itself during the overall lifting and the safety when it is in place, so the lifting tie point should be selected at the component. at the bottom chord node.
②Determination of lifting point and selection and configuration of lifting equipment
