In 1984 the Chinese Ministry of Construction appointed Zoomlion, formerly the Changsa Construction Machinery Research Institute, as the technical supervisor for the implementation of three tower crane technologies from the French POTAIN company. This gave Zoomlion the first opportunity to study and implement foreign technology and manufacturing concepts

In 1996 ZOOMLION marketed their full frequency altering tower crane series being the first and only Chinese tower cranes to be equipped with international advanced technologies bringing their products upto the same standard as those of the leading international crane manufacturers.

Putting their 40 years of high level R&D into good use, Zoomlion tower cranes are of the solid structural design, with a reliable electrical control system and excellent safety and reliability standards, creating a series of the first and only in and from China .

Zoomlion has the largest export volume of tower cranes in China, with exports to Africa, Qatar, U.A.E, Kuwait, Eastern and Western Europe, India, Asia, North and South America and Oceana.

Today Zoomlion are the Nr. 1 manufacturer of medium and large tower cranes in China . They are the first to use micro-computer-control technologies; the first to use the completely-frequency-alteration-technology for tower cranes; the first to equip the tower cranes with lab instruments; they manufactured the first hoisting and concrete placing crane and have designed and implemented more advanced tower crane technologies into their cranes than of any other manufacturer in China will ever be able to do.

With their 50 years of expert recognition within the industry and through their professional consistency, Zoomlion have laid down and drafted six key national and industrial standards for tower crane designs. Zoomlion however understands that these standards alone do not make Zoomlion professional and authoritative, but rather it should be quality oriented market competition that demonstrates their power. Fast growing construction projects require 24 hr work, thus reducing down time and achieving shorter construction times to increase profit is the crucial concern of every customer.

At the same time customers are primarily concerned with higher safety, superior efficiency and mechanical structure, no break downs of electrical equipment, higher sensitivity and greater lifting ability for tower cranes. Only by ensuring that these requirements are reliably met can high profitability for tower cranes be achieved.

Zoomlion tower cranes are equipped with weight limiters and moment limiters. The safety orientated Zoomlion tower crane is adapted with specially shaped square steel pipes and provides safe stress levels and low resistance.

Owing to ample experience in the implementation of the European F.E.M. standard and verification by the European CE standard, the safety of Zoomlion tower cranes has been increased to the highest level.

Zoomlion tower cranes are well known for their safety, reliability and low breakdown rates. Their sturdy steel structure and superior efficiency makes them completely reliable and worry free allowing operators to use the cranes with the utmost of confidence.

The reliability and superior safety of the tower cranes reduces breakdown rates to the lowest possible level making the cranes of tremendous commercial value to customers in the leasing business for example.

The superior reliability of the Zoomlion tower crane comes first from a focus on care and precision in technology and manufacture. The welding, the key process in manufacturing, plays an essential role in the fatigue resistance in the entire crane structure.

In order to maintain the crane as near to perfection as possible, inside and outside, Zoomlion makes use of submerged arc welding and mixed gas welding techniques. The quality of the cranes is not only dependent upon the raw materials used but also of the machinery and methods used in the production process. Zoomlion uses the precision controlled plasma cutting machine from the the german “Messer” company which ensures the precision of the raw materials used, better than any other machine available. Zoomlion also has the largest tower crane mechanism equipment laboratory in China , an extensive electrical laboratory, and Asia ’s largest tonnage electric-hydraulic-servo-controlled-fatigue-resisting testing bench.

The electric-hydraulic-servo-controlled-fatigue-resisting test bench is the first step in testing the performance of the tower crane. Only after a series of such tests and scientific experiments is each tower crane released into the market. The precise tooling is worth noting and if the customer’s construction site is located in an area of extreme cold or extreme heat, the clients will have an excellent opportunity to see the quality and reliability of the equipment and experience for themselves how well it holds up under actual conditions.

The tower cranes exported to exceptionally warm climates are further adapted to ensure that the electrical circuit and components do not overheat

Reliable technical controls

In the current state of development of tower cranes, even for first class international brands most non-core techniques have become standardised in quality, but professionals all know what counts most in choosing a tower crane is its electric systems.

The electrical control system is the brain of the tower crane. If the soul of the tower crane is endowed with its own inherent thinking abilities to enable it to deal with emergencies, customers can avoid countless dangers and failures caused by operational errors.

The reliability of the Zoomlion tower crane is rooted not only in the high quality of its foreign electrical components but also in the perfect match between its advanced design concept and the electrical components. The super combination of three top ranking global brands MITSUBISHI, SCHNEIDER and YASKAWA enables the patented PLC programmable controller to collect information from every part of the tower crane for processing, thus giving full play to the tower cranes intelligent brains.

The CPU and programmable controller both provide added convenience for a causation analysis and trouble shooting and save space in the electrical cabinet.

Stability, Precision and Efficiency

The greatest dangers to the tower cranes are two types of surges, the inertia serge and the current surge. These however are easily controlled by means of the patented frequency- alteration-stepless-speed regulation in the four mechanisms of Zoomlion tower cranes. The slewing operations starting and stopping are particularly stable, with quick and accurate positioning which definitely improves the efficiency of the tower crane. 1n 1996 innovative Zoomlion applied the digital converter technology to the tower crane. Thus a full frequency alteration and timing tower crane was produced bearing witness to the first international level achievement in tower crane design and manufacture.

The tower cranes are accurate, stable and rapid and are not susceptible to swaying when picking large loads as is the case with other brand names

High speed and high efficiency

As a tower crane manufacturer Zoomlion is aware as to the importance of time to its customer. Zoomilon tower cranes adopt a hook with automatic change over, quick coupling action in the connection of the slewing tower and jib and the root of the counter-jib, handy installation, and the unique trolleying-rope-double-tension device and an added tower section device with the anti-release function.

The Zoomlion cranes provide for fast installation and dismantling, fast crane hoisting, fast anchoring and adding of the tower sections and good acceleration and deceleration.

Zoomlion constantly work to improve their service and capability and in adapting to the new construction pace and changing construction technologies. Zoomlion tower cranes are always capable of solving the problems that customers deal with, whether the requirement be a longer jib to cover a larger operation area, a more powerful hoisting capacity for the single jib, or any other specific needs, for example wire rope anchoring and dismantling jib in mid air on special construction sites such a thermo power stations

Zoomlion have over 50 years experience in tower crane production and technology, with over 40 years top level R&D. Other Chinese tower crane manufacturers do not even come close to the quality, efficiency, safety and reliability of the Zoomlion tower crane TC series. Zoomlion are the Nr 1 crane manufacturer and exporter in China . Their technologies are patented both nationally and internationally.
