       纽科伦STI系列钢丝绳电动葫芦是由我公司开发设计的全新低净空系列产品。该产品按照欧洲FEM、DIN标准，对起重量系列、基型、机构工作制度和性能参数全面规划，以模块化设计思想研制开发。该系列产品达到了世界同类产品的技术水平。STI系列产品为国际市场普遍采用的结构形式之一，它的结构紧凑，空间利用率高。

  主要特点及优点：
   1、可有效提高葫芦起升高度，较普通CD运行式电动葫芦可使起升高度提高200-500mm。
   2、优良的三合一传动技术，起升减速机采用优质合金钢制成的渐开线斜齿轮减速机，三级减速，运行平稳、寿命长、性能可靠，避免了CD葫芦中间轴长距离传动的缺点。
   3、电机为专门设计的平面制动三相异步电动机，工作制为S3，有效提高了动力系统的工作级别。制动器电流通过整流器及控制器，实现高压启动低压运行，制动效果优良。
   4、运行采用蜗轮蜗杆减速器，使葫芦运行平稳，噪音小，系统寿命更长。
   5、可根据用户要求做到：葫芦起升、运行变频无级调速控制，遥控操作，过载保护，电机过热保护等多种功能。
   6、STI系列产品有多种起升吨位、起升高度、起升速度、运行速度可供用户选择。

    STI series wire rope electric hoist is our newly-designed low headroom series product. As per European FEM, DIN standard, generally plan the capacity series, basic model, and mechanism work system and performance parameter, develop and research with modularized design idea. This series product is up to technical level of world products of the same kind. STI series products are one of commonly used structure form in international market with compact structure and high space utility.

    Main features and advantages:
   1、Effectively uplift hoist lifting height by 200～500mm compared with common CD travel electric hoist.
   2、Excellent three-in-one transmission technical, lifting gearbox adopts good quality alloy structure steel made involute bevel wheel gearbox, 3-pole reducing, stable traveling, long life-span, reliable performance, avoid shortcomings like CD hoist intermediate shaft long-distance transmission.
   3、Motor is special designed plane brake 3-phase asynchronous motor, work system S3，JC=40% , effectively uplift work classification of electric system. Brake current pass through rectifier and controller, realized high voltage startup and low voltage travel, good brake effects.
   4、Travel adopts worm wheel and worm gearbox, make hoist travel more stable, lowwer noise, longer system life.
   5、Double speed of lift and travel, automatic speed conversion，small impact, stable traveling.We could do as per customer requirements: hoist lifting, traveling frequency nonpolar speed-adjustment control, remote control operation, overload protection, motor overheat protection and other functions.
   6、STI series products including various kinds lifting tonnage, lifting height, speed, traveling speed for customers' selection.
