THAT’S WHY WE CHOOSE CMAX TOWER CRANE

1. Advanced technology

The most advanced technology is adapted to our product design. All concerned matters such as raw material selecting, structure designing, working mechanisms, control system, efficiency, safety and reliability can reach the world level. And structure parts designed by three-dimensional software and force calculation software, make sure high Safety and perfect performance.

2. Craftsmanship

(1) New Advanced equipments for rust-removing applied in material pretreatment process to ensure rustless structure welding.

(2) Precise data control cutting machine ensures accurate specification of each component.

(3) CO₂ shielded arc welding ensures welding quality thereby enhances the longevity of the products.

 (4) High-quality surface coating that can meet different requirements of transporting and using. It is durable under environments of low, high, wet as well as oceanic environment.

(5) The pin-connected mast sections ensure a very short assembling time, visual check and easy assembling. Our mast’s cross-sections including: 1.6 x 1.6 m, 2 x 2 m and 2.45 x 2.45 m, easier for transport with dismountable panels design.

3. Leading technology of working mechanism

(1) Hoisting mechanism: Equipped with frequency inverter & multipolar dynamo (For lifting capacity≥10T). With Optima, the hoisting speed is optimized depending on the load. For each load level, the inverter authorizes the highest possible speed (hoisting or lowering), thus improving the productivity. It’s more convenient for maintenance work by the Human / Machine dialogue carried out by screen and keyboard.

(2) Trolleying mechanism: Equipped with frequency inverter(For lifting capacity≥10T) and wound-rotor motor can also applied to conduct speed regularly. Make trolley moving more economic and efficient. Diagnosis aid by screen and keyboard

(3) Slewing mechanism: Equipped with frequency inverter (For lifting capacity≥10T) or HRCV controller, make sure slewing with high productivity (stable speed, correct stopping angle), can control over several motors in the meantime.

4. Control system

Using of electronic components from world famous brands such as SCHNEIDER, YASKAWA, SIEMENS and MITSUBISHI, that ensures stability and reliability of the products. And all of the cables which applied in our product select domestic well-known brands.

5、CMAX tower crane is equipped with inspection system (like black box，optional), which could store 10000 tower crane operation reports, easy to inspect and diagnose.

6. CMAX tower crane will past all the inspection before leaving our factory, we always adheres the principle “Quality is the priority, management is the essential”. Every unit tower crane will be inspected by our quality control department, and the main welding line of tower crane will be inspected by ultrasonic flaw detection to ensure high quality.

7. CMAX have several excellent and professional encasement team, ensure our product avoid any damage in the shipping process.

8. CAMX can supply more than 40 professional & experienced overseas engineers for installation and after sales field.
