Tower crane QTZ250(TC7021/6528/6036/5544/5050/4558/4060) Topkit crane
The QTZ250 tower crane is a large-scale upper-slewing jack-up tower crane manufactured by our company. The model is novel in design, the tower body is a chip structure, easy to assemble and disassemble, lifting, turning, luffing, walking, jacking, etc. The institutions use foreign technology and have advanced and reliable performance.
This model has various types of use, such as walking type, fixed type, attachment type and internal climbing type, which can meet the construction technical requirements of various large and medium-sized construction projects and ensure safe and efficient construction.
The QTZ250 tower boom is 70 meters long, with a maximum hoisting weight of 12 tons. The maximum hoisting weight is 2.1 tons at 70 meters. The maximum lifting height is 50 meters. It can transport concrete to 240 meters or more.
The machine has the following main features:
1. The tower body is the standard section hydraulic jacking heightening, and the height of the tower crane can be determined according to the height of the building. The lifting capacity of the tower crane is not reduced by the rise of the tower crane.
2. The working speed is fast and the speed regulation performance is good. Work smoothly and efficiently.
3, the length of the boom frame varies widely, there are seven lengths of 40m, 45m, 50m, 55m, 60m, 65m, 70m, which can meet a wider range of engineering needs.
4. The driver's cab is independently placed on the side and has an open view, which creates a better working environment for the operator.
5. The safety device is complete, which can ensure safe and reliable work.
6. The whole machine is arranged reasonably and has nice appearance.
7. The boom is supported by rigid double tie rods and the structure is stable.
8. This machine is easy to operate and easy to maintain.
