It can provide lifting services for most medium and large construction projects. South Korea is one of the most important end markets for Yatai. We are honored to receive orders for various tower cranes and construction lifts from Korean customers. On August 8, 2020, Yatai Company signed a contract with a Korean long-term cooperative customer to provide a tower crane LTC5522-14 for its shopping center project in Seoul. Both the lifting motor and the arm motor of this equipment adopt the internationally renowned brand SEW supporting products, the inverter is the Siemens brand, and the quality of the whole machine is very reliable. After a close production cycle, the tower crane ordered by South Korea was completed from the production workshop in early November of the same year. After that, the company quickly completed the independent height trial installation and passed the 100% dynamic load test and the 125% overload static test in turn. After careful classification and packaging, we will ship the equipment by sea to the port of Incheon designated by the Korean customer on November 20, 2020.
