Flat-top tower crane, also known as topless tower crane, is obviously different from top-kit tower crane. The upper rod mainly bears tension, the lower rod mainly bears pressure, there is no alternative stress, which makes the installation and disassembly quick and easy. Flat-top tower crane’s unit weight is smaller, installation height lower, can be installed in restricted building site and is especially suitable for multi-tower cross operation.
QTZ100(6513) flat-top tower crane’s max. Lifting capacity is 8 tons with the radius range of 3-65m; the free standing height is 47m. With anchoring hook, it can reach as high as 215m. QTZ100(6513) is an ideal topless tower crane for high-rise building construction and cargo handling.


1. Top-Quality Q345B Manganese Steel
The original material is adopted from Baosteel and Laigang Group, scale purchase lowers the cost. The mast section of standard section, frame, the upper chord and lower chord of the jib, pull rod, tower hat are made of Q345B manganese steel, the strength of extension is improved by 30%, more safe and reliable.
2. Advanced Fully-Automatic Welding and Mixed Gas Arc Welding Technology
The feeding, welding and end-surface processing are all completed by the fully-automatic robot, and main parts are also welded by robot. Xinyu adopt international the most advanced carbon dioxide and argon mixed gas arc welding technology, which of big penetration, high welding quality and stability.
3. Famous Brand Parts and Components
We adopt Schneider electrical components, aviation-level plug, and stainless steel power box, all of which guarantee low failure frequency and easy installation. The hoist equipment adopts famous JIANGTE or DESHENG brand machine which are infused top-quality engine oil to ensure high reliability, non-maintenance and low repairing frequency. The slewing bearing adopt Ma On Shan FY or Xuzhou Rothe Erde equipment, duel-tempering-process technology makes the running more stable and greatly prolongs the whole machine’s using life.
4. Concentrate On Detail Quality
High-rigidity bolts adopt ship-level Dacromet technology which keeps the bolts from rusting more than 10 years. The tightening force of nf bolt is improved 30% compared to traditional bolt. The weight limiter is designed as tension ring structure, and the hoist limiter and luffing limiter are protected by cast aluminum shell, all of which largely prolong the devices’ using life.
5. Excellent Painting Technology
The whole equipment adopts impeller blasting technology thoroughly cleans the steel surface, removes internal stress of welding, enhances steel’s rigidity and hardness, improves the paint film’s adhesive force. Two priming and one finishing paint make the equipment beautiful, and improve the corrosion-resistance ability by 2 times. The platform, trolley and guard rail are processed by hot galvanizing after pickling and phosphating, further improving the rust-proof ability.
6. Comprehensive Safety Protection
Hoisting, trolleying, slewing are all equipped with moment or weight limiters; the wire are equipped with anti-skipping and anti-breaking device; the slewing trolley are equipped with anti-breaking axis and anti-falling and anti-tipping device; the electrical system adopts overflow and overload protection, and the PLC can realize self-diagnostics for easy maintenance.
