TC7525-16D 塔式起重机 基础、平衡重及压重 1.2-2
4、工作速度高，调速性能好，其中起升机构、变幅机构、回转机构采用当
今国际上最先进的变频无级调速方案，工作更加平稳可靠。
It has high working speed and good regulated speed performance. The technique
of the stepless speed regulated and frequency altering is used in the hoisting
mechanism, the trolleying mechanism and the slewing mechanism, so the crane
works more smoothly and reliably.
5、电气控制系统主要电器元件选用国际名牌，寿命比国产元件长 3～4 倍，
故障少，维修简单，工作可靠。
The main electric components are used world-renowned products, which service
life is 3～4 times longer than China-made counterparts with less failure, simple
maintenance and reliable working.
6、各种安全装置齐备，且为机械式或机电一体化产品，适应于恶劣的施工
环境，能确保塔机工作可靠。
All equipped safety devices are mechanical or mechanical-electrical integrated
products, and adapt to all badly conditions to ensure the crane working reliably.
7、设计在坚持切实符合国情，确保安全可靠原则的同时，尽可能地吸收采
用国内外成熟可靠的先进技术，来提高整机的技术水平，采用成熟可靠的先进技
术有：
The design of the crane is based on the actual situations in China and on the
safe-reliable operation principles. Greatly absorb and adopt the well-established and
reliable advanced technology to enhance its overall technical level at the same time in
the world. Well-established advanced technology adopted as following:
1) 专业电器厂引进法国 TE 公司技术生产的电器元件；
Electric components are made by specialty electronics factories that have
brought in the technology of TE company, France;
2) 引进国外先进技术并国产化了的重量限制器、力矩限制器、高度限位器、
幅度限位器、回转限位器、回转、变幅机构的制动器等安全装置。
Weight limier, height limiter, radius limiter, slewing limiter, slewing brake,
traction brake and similar safety guards are China-made based on the brought in
technology;
3) 小车防断绳装置（防溜车）和防断轴装置；
Rope-break-proof device (carriage slip-proof) and axle-break-proof device are
used on the carriage.
