名称：港口门座式起重机（PORT PORTAL CRANE）
港口门座式起重机（PORT PORTAL CRANE）
港口门座式起重机为移动式全回转、四连杆组合臂架（或单臂架）、齿条变幅（或钢丝绳变幅）、杠杆活对重平衡、滑轮组补偿、圆筒体门架，吊钩、抓斗、集装箱吊具作业的港口起重机。
该港口起重机是按照欧洲搬运工程协会标准（FEM）-《起重机结构和机构》，结合中国国家标准“GB3811起重机设计规范”和“GB6067起重机械安全规程”设计、制造。
本港口机械采用交流变频调速、PLC控制。司机室视野良好，电气系统采用优质的船用电缆和控制器，中心滑环集电器容量大、性能好，能适应港口的繁忙作业。各机构设有电气、机械的安全保护装置，确保起重机安全地工作。
该港口起重机是综合港口多货种码头的理想港口机械。外型美观、工作安全可靠、、维修方便、自重轻、能耗低、投资小，可广泛用于内陆及沿海港口装卸作业。
The port portal crane is the double link jib parallelogram（or single boom） ａnd full-circle slewing moving crane, rack and pinion luffing(or rope luffing), equalizing beam for counterweight, adopt the means of compensation with pulley block, gantry with cylindrical structure. It’s designed for the handling of bulk materials and general cargoes from vessel alongside sea and river ports, storage yards and stations. The crane can be fitted with either hook or grab. It can also handle container when it is equipped with container sling.
The port crane should be designed and manufactured in accordance with the European standard rules of ＂FEM＂, the China standard rules of ＂GB3811-1983 design rules for cranes＂ ａnd ＂GB6067-1985 safety rules for lifting appliances＂.
The port machinery adopt the means of AC inverter to change the motors’ speed, and the electrical system will be controlled by PLC. The cab is of panoramic-view type. The high quality marine cables and controllers are provided in electrical system. The central slip-ring collector has the advantages of large capacity and good property and is suitable for port frequent operation. Necessary electrical and mechanical safety protection devices are provided for mechanisms.
It’s the best ideal type in port. Featuring in: good appearance, compact structure, smoothness of running realiability of operational safety, performance excellence, simple and easy maintenance, light weight, low power consumption, small investment, long service life. Thus it can be widely used for handling operations in inlａnd and coastal port.
