TC7035B-16 使用说明书
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.
4) 起升机构排绳系统；Rope pay-off system for hoisting mechanism;
5) 牵引绳张紧系统；Traction rope-tensioning system;
6) 刚性双拉杆悬挂大幅度起重臂，起重臂刚度好，自重轻，断面小，风阻小，外形
美观，长度有几种变化，满足不同施工需要；
Large-radius hoisting jib suspended by double rigid pull rods, featuring good jib rigidity,
light jib weight, small jib cross-section, small wind resistance and nice-looking appearance and
several jib lengths, it is satisfied different construction needs.
7) 司机室独立外置，视野好，内部空间大，给操作者创造良好的工作环境；
Out-hung operator cabin, featuring excellent field of view, spacious interior, it is
satisfactory working environment to the operator.

8) 采用先进的联动台操纵各机构动作，操作容易，维修简单。
Advanced inter-active control console, the operator handles the mechanisms easy and
services simply.
8、设计完全符合或优于有关国家标准。
The design of the crane completely comforms to or is superior to the relevant national
standards.
由于该机具有以上特点，因而它适用于高层或超高层民用建筑、桥梁水利工程、大跨
度工业厂房以及采用滑模法施工的高大烟囱及筒仓等大型建筑工程中。
The crane is suitable for use in such large-sized construction projects as high-rise or super
high-rise buildings, bridge and water conservancy projects, large-span industrial buildings,
large gymnasiums, and high chimneys and silos constructed with slip form.
