加氢反应器 hydrogenation reactor
China Petroleum & Chemical Corporation (Sinopec) has installed the world's largest slurry-bed residue hydrogenation reactor in Zhoushan, Zhejiang Province, setting a record for hoisting the heaviest single piece of equipment in the country.
The reactor's outside diameter is 6.156 meters and it has a wall thickness of 320 mm. It is the core equipment of a key refining-chemical integration project of Zhejiang Petroleum & Chemical Co., Ltd. The record-breaking installation used the 5,200-tonne slidable hydraulic gantry lifting system for the main hoisting task, and a 2,000-tonne crawler crane coordinated the lift from the other end.
中国石油化工股份有限公司(中石化)在浙江省舟山市安装完成世界上最大的渣油床加氢反应器，创下中国最重的单件设备吊装纪录。
该反应器外径6.156m，壁厚320mm，是中石化浙江石油分公司一个关键炼化一体化项目的核心设备。此次破纪录的吊装采用了5200吨的可滑动式液压龙门吊装系统作为主要吊装设备，另一端由2000吨的履带吊装协同吊装。
磁悬浮列车 magnetic-levitation train
Performance checks of China's domestically-developed prototype magnetic-levitation train, with a designed top speed of 600 km per hour, began in Shanghai on June 21.
Maglev trains generate less noise due to the absence of wheel-rail friction. Besides, their minimum turning radius is only half that of a subway, allowing it to better bypass buildings in route planning.
6月21日，中国自主研发的最高时速600公里磁悬浮试验样车在上海开始性能测试。
磁悬浮列车没有轮轨的摩擦震动，因此产生的噪音较少。同时，列车最小转弯半径仅为地铁的二分之一，在路线规划中可以更好地绕开建筑物。
