The lifting weight of two rail-type container portal cranes is 70t and 60t respectively. The length and span are 53 meters and 27.5 meters. The lifting weight of tyred container gantry is 40t and the span is 23.47 meters. In order to meet the customer's requirements, Nucleon designers repeatedly demonstrated, determined the design plan and put it into production after several reviews. Due to the perennial operation of the equipment in the port, considering the wind, high temperature, humidity and other environmental factors, one is the key parts of the design and installation of the closed-loop anti-swing system, in case of strong wind and other external forces, can be stopped at any time. The second is the introduction of anti-corrosion source design, in addition to the special requirements of the paint, but also a number of structural parts horn optimization design, not only to facilitate welding, and improve the quality of painting. Third, when the equipment is running or stationary, the anti-skid system is added to ensure the safety of the equipment. At the same time, more than 10 kinds of main components such as reducer, brake and motor are imported to improve the service life of the equipment.
