英国曼彻斯特运河公司同伦敦的科特和派德纳公司以及英国水力学研究协会流体工程所作为顾问共同在曼彻斯特运河海船闸上设计、研制和装置了一种新颍拦船装置,以阻止船舶撞击闸门。 这种拦船装置能使2万吨以内的船舶在时速接近3海里的情况下在14米距离内停船。 拦船装置采用了直立在船闸两侧成对的大型液压缸。英国水力学研究协会负责设计、研制和供应液压缸设施。在曼彻斯特运 The Manchester Canal Company of the United Kingdom worked with Cotte and Pedlar of London and the Fluid Engineering Institute of the British Hydraulics Research Institute as consultants to design, develop and deploy a new barrage on the Canal Lock at the Manchester Canal to prevent the ship from impacting Gates. This type of barge enables vessels within 20,000 tons to stop within 14 meters at a speed of close to 3 knots. Barges use large hydraulic cylinders that stand upright on either side of the lock. British Hydraulic Research Association is responsible for the design, development and supply of hydraulic cylinder facilities. Shipped in Manchester
