Recently, the PT6020 flat-top tower crane designed and developed by the other party's special equipment inspection and testing center of Shandong Province has carried out the performance test. The new tower crane of Fangyuan Group passed the test smoothly, and the technical performance of the product reached the leading level of similar products in China. . According to GB/T5031-2008 (standard), the testing group carried out stress tests on the key structural members such as the lifting arm, balance arm, rotating tower body and diagonal strut of the other round PT6020 tower crane, and the weight limiter and torque limiter were applied. Safety protection devices such as height limit, amplitude limit, and swing limit are tested. In addition, tests such as rated load and overload were also carried out. The test results show that the Fangyuan Group PT6020 tower crane is a horizontal boom, trolley luffing, upper swing, and flat-head self-lifting tower crane. The three major mechanisms adopt variable frequency speed control, with large speed range and stable braking. The hoisting mechanism adopts a variable frequency motor with a rotary encoder, which can be controlled by closed loop or open loop speed control. The heavy load is lifted and lowered without slipping, and the speed brake can be realized, and the operation is stable without impact. The trolley luffing mechanism is composed of a semi-built-in planetary reducer reel and a frame of a variable frequency motor, and has the characteristics of speed brake, smoother starting and shifting, high transmission efficiency, safe and reliable braking, and accurate positioning. This type of tower crane has a maximum lifting capacity of 10 tons and a boom length of 60 meters. It can also achieve an arm length of 50 meters and 40 meters according to user requirements. The main limb structure of the standard section of the tower body is made of angle steel material, which is convenient for transportation and installation on the construction site, and better meets the different needs of various users.
