Hydraulic Tower Crane

Hydraulic tower crane is a kind of rotary crane installed on the upper part of the towering tower, which is mainly used for the vertical and horizontal transportation of materials and the installation of building components in the construction of houses, using the lever principle of Archimedes. That is, the force at both ends is equal to the product of the force arm, and the longer the force arm, the less force is required.

The hydraulic tower crane is composed of three parts: metal structure, working mechanism and electrical system.

Metal structure: including tower body, boom, base, attachment rod, etc

Working mechanism: there are four parts: lifting, luffing, slewing and walking.

Electrical system: including motors, controllers, distribution frames, signals and lighting devices, etc.

The reason why the hydraulic tower crane can "grow taller" is very simple, it is assembled one by one, which involves 3 very important parts: the standard section, the climbing section and the hydraulic jack.

The standard section is the metal bracket of the tower crane; The second is the "climbing section", and the lifting of the tower crane depends on this part.

The "climbing section" is a climbing casing that is installed on the top of the tower. The height and size of the climbing section are larger than the standard section, so the "climbing section" is like wearing a hat, which is put on the standard section, thus making room for upward movement.

The hydraulic jack is installed inside the climbing section, and the operator will operate the hydraulic system to raise the climbing sleeve to make room for the installation of the new standard section. When the climbing sleeve rises to a certain height, the operator aligns the new standard section with the main structure of the tower crane and bolts it. Finally, the operator lowers the climbing sleeve so that it wraps around the bottom of the crane again, completing a "grow taller" cycle

The tower crane is so stable that it needs a stable tower crane foundation, which is very important. The factor related to the stability of the crane is a large concrete platform, which the construction team will spend weeks pouring before the crane arrives, which is the foundation of the crane.

The structural design of the tower crane makes it have high stability. Its dead weight and the counterweight on the balance arm work together to maintain the balance of the tower crane. Furthermore, the end of the balance arm of the tower crane is usually equipped with a large number of counterweights, which can offset the torque generated when lifting materials, so as to maintain the stability of the tower crane.

According to the operation specification, when the tower crane encounters strong winds, it is necessary to loosen the brake of the slewing mechanism, so that the boom can rotate with the wind, so as to release the kinetic energy of the wind load to the greatest extent, enhance the wind resistance and resist the attack of strong typhoons. So we will see tower cranes rotating with the wind in typhoon weather.
