| custom_attr2︰ | Properties and merits of QTZ40(4208)tower crane
1. The load moment of QTZ40 tower crane is 400KN.m,the maximum lifting weight is 4T, and the maximum range is 42 meters.
2. The lifting height of QTZ40 tower crane can be 29 meters when standing stationary a lone, and 120 meters when anchored,suitable for the construction of building lower than 40 stories. The structure of this tower crane is rational, for the main functioning steel parts, such as the tower and the crane,are are made up of seamless steel tubes with proper hardness,little wind resistance and a pleasant appearance.
3. QTZ40 tower crane adopts the Tianshui electric parts which are most famous in China.These high-quality parts can serve for a long time, reducing breakdowns and improving efficiency.
4. QTZ31.5C tower crane has helmet structures with two hoisting points, adopts small trolleys, hoists with upper slewing liquid pressure, and it can be installed quickly and conveniently.
Properties and merits of QTZ400(4708)tower crane
1. The load moment of QTZ400 tower crane is 438KN.m,the maximum lifting weight is 4T, and the maximum range is 47 meters.
2. The lifting height of QTZ400 tower crane can be 29 meters when standing stationary a lone, and 120 meters (ratio 2) when anchored,suitable for the construction of building lower than 40 stories.With advanced parameters, reliable properties, rational structures and a pleasant appearance, the tower crane is an ideal machine for construction enterprises of all sizes.
3. QTZ400 tower crane has level jibs,adopt small trolleys and hoists with upper slewing liquid pressure.All its indexes meet or surmount the national standards.
4. QTZ400 tower crane is fixed with advanced security equipment,load moment limiter and weight limiter.So it is highly sensitive and easy to maintain ,able to effectively avoid accidents.
