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. However, due to prolonged usage, […]

I. 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. Therefore, 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 […]

Section I: Acquisition and Rental of Tower Cranes 1. Purchasing New Tower Cranes To ensure operational safety and compliance, all new tower cranes must be procured from manufacturers with valid production licenses. The following documentation is mandatory upon purchase: Equipment compliance certificates. Warranty certificates for critical components, including high-strength connecting bolts and hoisting wire ropes. […]

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. Therefore, each crane is equipped with a unique lifting capacity chart corresponding to its operating radius, commonly […]

I. 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 […]

Tower cranes are a fundamental component of modern construction, playing a vital role in the efficiency and safety of building projects. Given their tall, upright structures and intricate designs, the proper installation and acceptance of tower cranes are of utmost importance. Any oversight in this process can lead to catastrophic accidents, potentially resulting in loss […]

Tower cranes are essential in the construction industry, facilitating the lifting and moving of heavy materials at significant heights. However, like any mechanical equipment, tower cranes are susceptible to wear and failure, which can significantly impact their operational efficiency and safety. The wear on tower crane components can generally be categorized into two primary types: […]
