The FZQ800P-40T topless tower crane is quite different form the traditional tower craning machinery in structural design. It is safe in operation, light in dead weight, high in working performance, good in mechanical sensitivity, and precise in lifting height. It mainly applies to the power plant, shipyard, petrochemical factory, metallurgy plant, and many other places where the industrial equipment need to be positioned precisely. This topless tower crane is the achievement of our ten year's effort in serving the foreign customers, so its thoughtful design can meet the needs of foreign customers well.

1. The good configuration is the insurance of high quality. All the key parts and components of our topless tower crane are purchased from the world renowned suppliers.
2. In order to adapt our machine to the complex foreign natural environment, we put various poor weather conditions in consideration, such like the rain, high temperature, and moisture. We did a lot in rust proofing, leakage proofing, and electronic elements insulating, as well as the performance testing.
3. In order to adapt our machine to the foreign humanistic environment, we learn about the operation custom of foreign operator, and add a number of humanized functions into the product, such as the collision and interference proof system, multiple three dimensional interlock protection, rough operation protection, capsule style control room with constant temperature, and remote monitoring.
4. In order to adapt our machine to the foreign electric power supply systems and possible emergencies, such like the frequent power failure, voltage fluctuation, irregular wave, and dust pollution. Our topless tower crane adopts the large voltage margin to protect the electrical part from being damaged by electrical surge.
4. None of the parts of our product exceed the dimension or weight limit of highway transportation. The sectional area of our tower is 2.6×2.6m2, which is extremely convenient for the truck to transport.
5. Our patent, quick-type pin connection structure, can simplify the erection of our product greatly.

As a professional crane manufacturer and supplier, we offer a variety of products that includes luffing jib tower crane, overhead crane, box girder type gantry crane, large lifting device, stationary derrick crane, and more.
