(Summary description)Different types of cranes usually use lifting torque as the main control. When the working range of the good price and quality QTZ250 (7030) tower crane increases or the heavy object exceeds the corresponding rated load, the overturning moment of the heavy object exceeds its stable moment, which may cause the tower crane to collapse.

Different types of cranes usually use lifting torque as the main control. When the working range of the good price and quality QTZ250 (7030) tower crane increases or the heavy object exceeds the corresponding rated load, the overturning moment of the heavy object exceeds its stable moment, which may cause the tower crane to collapse.

Information

The ratio of the height of the good price and quality QTZ250 (7030) tower crane to the size of the bottom support is large, the center of gravity of the tower body is high, the torque is large, the starting and braking are frequent, and the impact force is large. In order to increase the stability of the good price and quality QTZ250 (7030) tower crane, let's follow the editor of Huaxia Group to analyze the main reasons for the overturning of the tower crane:

1. Overload. Different types of cranes usually use lifting torque as the main control. When the working range of the good price and quality QTZ250 (7030) tower crane increases or the heavy object exceeds the corresponding rated load, the overturning moment of the heavy object exceeds its stable moment, which may cause the tower crane to collapse.
Second, inclined hanging. The overturning moment of the good price and quality QTZ250 (7030) tower crane will increase when the heavy object is slanted, and the horizontal component force and the vertical component force will be generated at the lifting point. An additional overturning moment occurs at the bottom support point of the tower crane, which reduces the stability factor and causes collapse.
3. The tower crane foundation of the good price and quality QTZ250 (7030) tower crane is uneven, the ground endurance is not enough, and the excessive verticality error will also cause the overturning moment of the tower crane to increase and reduce its stability. Therefore, we should carry out strict testing of the good price and quality QTZ250 (7030) tower crane from these key factors to prevent major equipment and personal safety accidents.

5015 tower crane

5015 Tower crane is the most commonly used lifting equipment on construction sites. The extension (height) of each section (hereinafter referred to as "standard section"). It is used to lift construction raw materials such as steel bars, wooden beams, concrete and steel pipes. The function of the 5015 Tower crane is to bear the upper load transmitted by the jib pull rope and the balance arm pull rope, and directly transmit 5015 Tower crane to the tower structure through the rotary tower, turntable, bearing seat and other structural components. 5015 Tower crane ；50 represents the boom length of 50 meters, and 15 represents the maximum lifting capacity of the boom tip of 1.5 tons.

QTZ250 (7030) tower crane

Model QTZ250 (7030) tower crane with lifting torque of 250tm.Tower crane: the boom form of tower crane is divided into horizontal type and pressure bar type. When the boom is horizontal, the truck runs along the horizontal boom and the luffing motion is balanced. The boom is long, but the boom weight is large. When the boom is of compression bar type, the luffing mechanism leads the boom to pitch luffing. The luffing motion is not as stable as the horizontal type, but its self weight is small. The lifting capacity of the tower crane varies with the amplitude. The product of lifting capacity and amplitude is called load moment, which is the main technical parameter of this crane. Through the slewing mechanism and slewing ring, the tower crane has large lifting height and large inertia mass of slewing and walking, so it needs to have good speed regulation performance. In particular, the lifting mechanism is required to be fast under light load, slow under heavy load and micro motion in place. Generally, in addition to resistance speed regulation, eddy current brake, frequency modulation, pole changing, thyristor and electromechanical combination are often used for speed regulation.

QTZ40 tower crane

QTZ40 tower crane is a new type of tower crane for construction. The machine is in the form of horizontal boom, trolley luffing and upward rotary hydraulic jacking; The working range is 45m-2m; The lifting capacity is 4T at quadruple rate and 2T at double rate; The rated lifting moment is 400kN m； The lifting height is 35m for independent use and 100m for attached use.
