摘要
 胎式集装箱龙门起重机，简称RTG，是码头堆场装卸集装箱的一种专用设备。目前全球RTG的保有量约6000余台，占各种集装箱龙门起重机总量的90%以上。
 由于RTG采用柴油发电机组提供动力，存在能耗高、运行成本高、污染重等缺点。同时，港口环境受到了较大的污染。
 本文档采用刚性滑触线供电方案完成了由城市电网直接供电的RTG电动化改造（简称ERTG），实现了将节能减排、节支增效和可灵活转场作业集于一身的改造设想。
 其基本原理是：在集装箱堆场箱区边，架设刚性滑触线供电线路，电网电力通过滑触线和移动供电装置输送到RTG，移动供电装置随RTG同步移动，从而实现对RTG的移动供电。

 The Design Planning of “Electricity Instead of Oil” for RTG And 3D

Abstract
 Rubber-tyred container gantry crane ,which is short for RTG，is a special equipment for to handling containers in terminal yard .Nowadays the number of RTG has reached over 6000,which is accounting for 90% of the total.
 But RTG adopt the diesel generator sets to supply the driving force. It existed the problems of high energy consumption, high operating costs, pollution .At the same time, diesel generator sets produced the exhaust air, the leak of noise and oil, water etc. That made the bigger pollution to the terminal.
 After doing the research on the electric RTG and comparison between several technical plans, we adopt the plan of the sliding - touch line to finish the “electricity instead of oil” for the RTG by the urban power networks directly(which is short for ERTG).It realized the assumption as a whole of low energy consumption ,low emissions ,high efficiency and flexible working.
 The basic principle is erecting power supply networks by the sliding - touch line. RTG gets power through the sliding-touch line and mobile power supply device from the networks. While the mobile power supply device is synchronous moving with RTG, it realized the power supply to RTG.

Key words: Electricity instead of oil ; Sliding touch line ; 3D design；Sync Mobile; Comparison Argument
