Now, society is developing at a rapid pace—especially since the Fifth Plenary Session of the 18th Central Committee, when rural development has become the top priority. And this very fact has made our crane industry a hot sector. Today, let’s take stock of the crane industry.
What is a crane? We commonly refer to it simply as a "crane," but it actually has another name: a "crane-lift truck." These cranes come in two types—large and small. A small crane is essentially a compact lifting machine combined with a chassis, designed as a versatile transport vehicle. It consists of key components such as a boom, turntable, frame, and outriggers. The crane’s mechanical movements—like luffing, telescoping, slewing, and hoisting—are achieved through the coordinated operation of these mechanisms, allowing for efficient lifting tasks when various motions are combined.
Cranes are categorized into mobile and stationary types. Mobile cranes include truck cranes, crawler cranes, and gantry cranes, among others. Stationary cranes, on the other hand, encompass dock cranes, portal cranes, and tower cranes. Among the mobile cranes commonly seen in our daily lives are truck-mounted cranes, telescopic cranes mounted on vehicles, and even homemade mini-cranes. We’ll focus specifically on the knowledge related to these mobile cranes.
Based on our current environment, the tonnage we typically use is 3–20 Tons—some areas require compact vehicle bodies, and since these don’t need license plates, you can opt for custom-built mini cranes. Some might wonder if these homemade mini cranes could actually be less powerful than their commercial counterparts. But don’t let their small size fool you; despite their compact design, these cranes come packed with high-end features: power steering, 360-degree rotation capability, fully hydraulic outriggers, and a robust chassis that extends backward for added reach. 1 Rice.
A mobile crane is a crane whose lifting mechanism is mounted on a universal or specialized vehicle chassis, while retaining the mobility of a conventional truck. To meet the demands of operating in challenging, off-road conditions, specialized versions of mobile cranes with enhanced off-road capabilities have been developed.
