Tëtruck-mounted craneis highly popular in the special vehicle market. It finds extensive applications in various fields such as garden construction, engineering construction, factory warehouses, ports and docks, and many others. With an extremely wide range of uses, it has become an essential piece of equipment in many industries. When you decide to purchase atruck-mounted crane, the salesperson will likely mention several professional terms and parameters related to the crane. But do you truly understand the meaning of these terms? For instance, moment, maximum working radius of the crane, maximum lifting height, and so on. Comprehending the significance of these terms can greatly assist you in making a better choice and purchasing atruck-mounted cranethat meets your specific needs.
Let’s start with the term “moment.” Moment is calculated as the product of force and force arm, which in the context of a crane is the product of lifting weight and working radius. Essentially, the moment represents the lifting capacity of the crane. For each specific specification of crane, the moment is fixed. There is an inverse relationship between the working radius and the lifting weight. As the working radius increases, the lifting weight decreases, and vice versa. When the working radius is smaller, the lifting weight is larger, and when the working radius is larger, the lifting weight is smaller.
For example, let’s consider a 10-ton crane. The moment of this crane can be calculated as follows: 2.5 × 10 = 25 ton·meters. Here, 2.5 meters is the reference distance at which the crane can actually lift. Now, let’s say we want to know how much weight the crane can lift at 5 meters. We can calculate this by dividing the moment by the working radius, so 25 ÷ 5 = 5 tons. However, it’s important to note that when considering the actual lifting weight, we need to take into account the weight of the boom itself. Due to the weight of the boom, the actual lifting weight will be less than 5 tons.
Similarly, for a 20-ton crane, the moment is calculated as 2.5 × 20 = 50 ton·meters. So, if we want to know how much weight the crane can lift at 6 meters, we divide the moment by the working radius, giving us 50 ÷ 6 = 8.3 tons. Again, considering the weight of the boom, the actual lifting weight will be less than 8.3 tons.
The maximum working radius is another crucial parameter. The maximum working radius is defined as the length from the center of the column to the hook when the boom is fully extended horizontally. This measurement gives an indication of the farthest distance at which the crane can reach to lift an object. Understanding the maximum working radius is essential for planning and executing lifting operations in different work environments. For example, in a construction site with limited space, knowing the maximum working radius can help determine if the crane can reach the required lifting locations without having to reposition the vehicle. In a port or dock setting, a larger maximum working radius may be required to handle cargo from different parts of the shipping area.
The maximum lifting height is also an important consideration. The maximum lifting height is the vertical distance from the center of the hook to the ground when the boom is at the maximum elevation angle and the maximum boom extension. This parameter is crucial for applications where objects need to be lifted to significant heights. For instance, in high-rise construction projects, knowing the maximum lifting height of the crane is essential for determining if it can reach the upper floors of the building. It also helps in planning the placement of materials and equipment at different heights.
Outrigger span is another term that plays a significant role in the operation of atruck-mounted crane. The outrigger span is the horizontal distance between the centers of the two outriggers when the horizontal cylinder is extended. The maximum outrigger span is the horizontal distance between the centers of the two outriggers when the horizontal cylinder is fully extended. A larger outrigger span provides greater stability to the crane during lifting operations. When the outriggers are extended to their maximum span, they distribute the weight of the crane and the load more evenly, reducing the risk of tipping over. This is especially important when lifting heavy loads or operating in uneven terrain.
Total mass is a term that combines several components. Total mass is equal to curb weight plus rated load mass. Curb weight, in turn, is the sum of the curb weight of the chassis and the weight of the crane. The curb weight of the chassis is the weight of the vehicle without any additional loads. The weight of the crane includes the weight of the boom, the hoisting mechanism, and other components of the crane. Rated load mass refers to the weight of the goods carried by the vehicle as specified in the announcement. The larger the rated mass, the more goods the vehicle can load. Understanding these components of total mass is important for ensuring that the crane is not overloaded and for complying with weight restrictions on roads and bridges.
Do you now understand all these professional terms? If so, then take action quickly. Currently, the price oftruck-mounted cranes is still relatively cost-effective. Investing in atruck-mounted cranecan bring many benefits to your business or project. Whether it’s for construction, logistics, or other industries, a truck-mounted crane can improve efficiency, reduce labor costs, and enhance safety. By understanding the professional terms and parameters oftruck-mounted cranes, you can make an informed decision and choose a crane that best suits your needs.
In conclusion, understanding the professional terms related totruck-mounted cranes is essential for anyone considering purchasing or using one. These terms provide valuable information about the capabilities and limitations of the crane, helping you make a wise investment and ensure safe and efficient operation.
