It took a full three years of unwavering dedication from the start of research and development to the acquisition of this invention patent. Led by senior engineer Pang Meixing, the company’s mechanical technology team, inspired by the Jianhuan spirit of “rolling up one’s sleeves and working with all one’s might”, surmounted layer upon layer of technical hurdles, scaled the lofty peaks of science and technology, and ultimately claimed the prestigious invention patent.

This invention patent controls the on – off of the entire circuit of the tower crane through a contact device. In the event that the operator loses consciousness or is influenced by uncontrollable external forces, as long as the operator releases their grip, the machine will halt regardless of the position of the operating lever. This effectively prevents major safety accidents and provides safety protection. Its economic value and social significance are both profound and far – reaching. It not only addresses the potential safety hazards in current tower crane operations but also fills a technical void in safety protection for tower crane operations in the domestic market. It stands out uniquely among peer enterprises nationwide.

The attainment of this invention patent has elevated the technical quality of the company’s products, strengthened the company’s voice and competitiveness in the market. It both adheres to Jianhuan’s corporate spirit of “pioneering and being bold in innovation” and fully expounds the core values of “originating from technology and commanding the future”. This achievement has given Jianhuan an added edge, propelling the company to stride forward vigorously towards the Jianhuan dream of “establishing an international – brand enterprise”.
