Descriptions of Tower Crane
The 8T QTZ80 tower crane features a dynamic lifting torque of 80 tm and max. lifting capacity of 8 tons. The max lifting capacity at its max radius of 60 meters is 1 ton.
The hoisting mechanism of the 8T QTZ80 tower crane feature a double speed, three-phase winding asynchronous motor drive, it works in coordination with the motor start speed regulation resistor and the eddy current brake. This significantly improves the motor's starting and adjusting performance. A multi-speed mechanism can gradually accelerate the machine and meet all performance requirements. The luffing mechanism adopts a planetary reducer with a simple structure and small size, which allows the lifting trolley to work at dual speeds of 20m/min and 40m/min, respectively. The slewing mechanism adopts the form of torque motor and planetary reducer, which can be regulated through the variable frequency system. Moreover, the structure is compact, the transmission efficiency is high and the noise is small.
