The boom form of Wholesale QTD 160 tower crane is divided into two types: horizontal type and pressure rod type. When the boom is horizontal, the load trolley runs along the horizontal boom to luff, and the luffing movement is balanced. When the boom is a pressure rod type, the luffing mechanism drags the boom pitch and pitch, and the luffing movement is not as stable as the horizontal type, but its own weight is small.
The lifting capacity of the Wholesale QTD 160 tower crane varies with amplitude. The product of the lifting weight and the amplitude is called the load moment, which is the main technical parameter of this kind of crane. Through the slewing mechanism and slewing bearing, the lifting height of Wholesale QTD 160 tower crane is large, and the inertial mass of slewing and walking is large, so it needs to have good speed regulation performance. Install it in place. Generally, in addition to resistance speed regulation, eddy current brake, frequency modulation, pole change, thyristor and electromechanical combination are often used for speed regulation.
