Brief of 600t Hydraulic Strand Jack with Synchronous Lifting System
Synchronous lifting jacks are a new form of large-scale component lifting equipment that consists primarily of a lifting jack, hydraulic pump station, and control system. The concept is to combine prestressed anchorage technology with 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 lifting jack piston to extend and retract, and drive the steel wire. The stranded wire and components are lifted and lowered in order to achieve synchronized lifting and lowering of massive components.
Process and Technology of Synchronous lifting jack
1. Scope of Application
This technology is appropriate for elements of large-scale public projects.
2. Methods & Features
Lifting method
Currently, the methods of "steel strand suspension load-bearing, hydraulic lifting jack cluster, and computer control synchronization" are widely used. The two ways are as follows:
(1).The pull-up lifting method involves anchoring the upper end of the suspended steel strand to the permanent column of the load-bearing structure with a hydraulic lifting jack. Special tools are used to anchor the lower end and lifting member. Connected together, like "lifting water from the good platform," the hydraulic lifting jack grips the steel strand and raises it up, raising the component to its installation height. This scheme is a pull-up lift.
(2).② Climbing type (climbing pole): the upper end of the suspended steel strand is fixed on the permanent structure (or foundation or temporary reinforcement facility connected with the permanent object), and the hydraulic lifting jack is set at the lower end of the steel strand. The anchor is attached to the component; like a "monkey climbing pole," the hydraulic lifting jack clutches the steel strand and climbs up, elevating the component to the installation height.
The climbing type is best suited to lifting upright parts with a high lifting height, large projection area, and low weight, such as TV tower steel mast antennas.
