Modern supertall construction relies completely on the integrity of the hydraulic jack up system. This system allows the crane to insert new mast sections and self-climb into high elevations.
The entire self-climbing sequence depends on custom-engineered telescoping hardware. Key components include the telescoping cage (climbing frame), high-strength joint pins, guide rollers, hydraulic cylinders, climbing beams, and safety pawls. If any single weldment or material component exhibits fatigue, structural failure is risk-magnified under wind loads and shifting centers of gravity.
As a leading supplier, Dazheng ensures that every climbing frame and joint pin undergoes rigorous Non-Destructive Testing (NDT) to sustain extreme torsional force at heights exceeding 300 meters.
Our main products include various types of tower cranes, agricultural machinery, plate rollers and leveling lines, which are widely used in many fields such as construction, agriculture and manufacturing.
Our production plant covers an area of 208 acres, with 50,000 square meters of modern production workshops equipped with advanced production equipment. We have introduced large-scale CNC gantry five-face machining center HF-8M from SNK, Japan, AREA-EV8 and MECOF M1040 five-axis linkage moving column boring and milling machining centers from FPT, Italy, as well as large-scale CNC floor milling and boring machine TK6920A from Wushong and Kunming Machine Tool of Shenji Group and TK6913 from Wuhong Machine Tool Co. and other high-end equipments.
These advanced tools provide the best service for molds and have the ability to process major equipment for molds, nuclear power, heat and power, wind power, hydropower, and ships. In addition, we are equipped with large measuring instruments such as 3D measuring instruments to ensure the precision and quality of our products.
Our systems represent the frontier of safety, performance, and metallurgical reliability.
Our climbing cages utilize structural steel profiles made of Q355B and Q460. These alloys prevent structural cracking at low temperatures and support extreme load distributions during the critical jacking phase.
Equipped with high-performance power packs, our hydraulic units utilize proportional flow valves to guarantee uniform cylinder extension, mitigating structural lean during lifting operations.
Integrating mechanical lock pins, gravity-activated safety pawls, and electronic pressure sensors to prevent pressure drops. In the event of a hydraulic leak, the load is mechanically locked instantly.
