1. Introduction: What are Jib Tower Cranes?
Jib tower cranes are towering structures commonly seen on construction sites. They are used to lift and move heavy materials and equipment, making them essential for various construction projects. These cranes consist of a vertical mast, or tower, and a horizontal jib arm that can rotate 360 degrees.
2. How Do Jib Tower Cranes Work?
Jib tower cranes operate using a combination of hydraulic systems, counterweights, and electric motors. The tower provides stability, while the jib arm extends and retracts to reach different areas of the construction site. The lifting capacity of these cranes can range from a few tons to several hundred tons, depending on the model.
3. Types of Jib Tower Cranes
3.1. Hammerhead Cranes
Hammerhead cranes are the most common type of jib tower cranes. The jib arm extends horizontally from the top of the tower, resembling a bridge. These cranes are known for their high lifting capacity and are often used in large-scale construction projects.
3.2. Luffing Jib Cranes
Luffing jib cranes have a jib arm that can be raised or lowered, allowing for greater flexibility in congested construction sites. These cranes are ideal for urban areas where space is limited.
3.3. Flat Top Cranes
Flat top cranes have a flat jib arm that resembles a table. These cranes are popular for their ease of assembly and disassembly, making them suitable for projects with frequent crane relocation.
3.4. Self-Erecting Cranes
Self-erecting cranes are portable and can be easily transported and set up on-site. These cranes are commonly used for smaller construction projects or in areas where a large crane is not feasible.
4. Advantages of Jib Tower Cranes
Jib tower cranes offer numerous advantages in the construction industry. They provide exceptional lifting capacity, allowing for the efficient movement of heavy materials. Their ability to rotate 360 degrees enables operators to reach various parts of the construction site without repositioning the entire crane. Additionally, the sturdy construction of jib tower cranes ensures stability, even in challenging weather conditions.
5. Applications of Jib Tower Cranes
Jib tower cranes are used in a wide range of construction projects, including high-rise buildings, bridges, dams, and infrastructure development. These cranes are also employed in the installation of heavy machinery, such as HVAC systems and large-scale construction components.

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.
