QTZ250tower by my company is developed and large tower. The tower for turning on theshelf, the car horn level arm, hydraulic ZiSheng walk type tower. Rated liftingtorque for 2500 kN m., biggest independent lifting height for 46 m, maximumlifting weight for 12 tons, the most greatly place up to 3 tons of weight, themost greatly for 70 m.

The tower design is reasonable, the standardsection for chip, and greatly reduce the costs of transportation. Modellingbeautiful, quality excellent, safe, reliable, and is the building of enterpriseideal building construction machinery. The machine has a hoisting, slewing, derricking and roof up, walk five kinds of work units, hoisting, slewing, luffing independently or composite action to improve the work efficiency. Roofup mechanism for mai take high or drop tower; Used to expand the space walk towork. Three big institutions through the variable frequency speed regulationproduce various different speed to meet the needs of the different workingconditions. Hoist boom can be positive and negative spin 540 °, slewing, luffing flexible reliable, hoisting in place accurate, and can be one-time meet in vertical and horizontalconstruction of transportation needs.

The machine has the weight limit device, torquelimiter, lifting height limit device, amplitude limit device and rotarylimiters device. Safety protection device is sensitive and reliable, ensure thenormal work tower. In addition, but also is equipped with the rest platform, such as fence safety protection facilities. The driver room independent sidebuy, beautiful modelling, vision and interior space is big, easy to operate.

This machine can be widely used in high-risehotel, residential, industrial building, top of the large span industrialworkshop, such as high chimney large construction projects.
