Tower crane operations involve significant risks, particularly during lifting tasks. To minimize accidents and ensure safe operation, the following preventive measures are recommended: 1. Enhancing Safety Awareness Objective: Strengthen workers’ awareness of safety protocols. Promote adherence to established regulations to reduce unsafe behaviors. Implementation: Conduct regular safety training sessions. Integrate safety drills into routine operations […]

To adjust the rotational speed of an asynchronous motor, we can start with changing the following three parameters: the number of pole pairs of the stator winding, the slip ratio of the motor, and the frequency of the power supply. Changing the first parameter affects the synchronous speed. Changing the second parameter only enables speed […]

Introduction to Tower Crane Reducer Housings The reducer housing of a tower crane serves as a critical structural component, providing support and protection to the gears and mechanical parts inside. Manufactured primarily from cast iron, typically of grade HT150, these housings are designed to withstand significant mechanical stress during operation. با این حال, due to prolonged usage, […]

من. Purchase (Rental) of Tower Cranes 1. Purchase of Tower Cranes When purchasing a tower crane, it must be bought from a professional manufacturer with a valid production license. The manufacturer should provide technical documents such as the whole-machine certificate, quality guarantee for high-strength connecting bolts, quality guarantee for hoisting wire ropes, quality guarantees for […]

Tower cranes are large-scale hoisting machinery commonly used in building construction. Due to the structural characteristics of tower cranes, the tower body bears relatively large eccentric bending moments. بنابراین, their installation and dismantling require strong technical skills, and safety management is rather difficult. A slight oversight can lead to major accidents with the destruction of […]

The lifting capacity of a tower crane refers to the weight that its hook can safely lift. This capacity includes the weight of the slings, lifting devices, and containers. The lifting capacity varies with the crane’s working radius. بنابراین, each crane is equipped with a unique lifting capacity chart corresponding to its operating radius, commonly […]

من. Safety Precautions for Tower Crane Foundation Pouring The bearing capacity of the tower crane foundation ground should not be lower than the ground resistance value specified in the technical requirements of the tower crane foundation drawing.The foundation of a tower crane is the key to its stable operation. The ground beneath it must possess […]

Tower cranes with telescopic tower structures and horizontal jib configurations, such as the QT16-type quick-assembly lower slewing tower crane, often follow a sequential procedure for installation. Below is a detailed step-by-step guide: 1. Stabilizing the Base Frame Extend all four support legs and lower the support jacks to lift the tires off the ground. Adjust […]
