In order to better support the use of container cranes, HXME has actively invested manpower and material resources in year 2018 to develop a new generation of rail-mounted container cranes used in back yard, and has developed a new type of critical gauge rail-mounted gantry crane of which the crane gauge is adjustable, and with patented technology. The crane rail has no gnawing or small shaking when the bogie is running, and has good rigidity. The new products were put into operation in year 2019 and year 2020 respectively, and were well received by clients. Since then, the products provided by HXME have covered almost all port machinery equipment, which enriched the company's product categories.
