Q&A and Explanations Related to Truck-Mounted Cranes

1. What brands of crane machines are there for truck-mounted cranes?

For truck-mounted cranes, the prominent brands available in the market include: XCMG, Shimei, Zoomlion, Furukawa, among others. When it comes to the chassis, the common options are: Dongfeng, FAW, JAC, Foton, Jiangling, and so forth.
It’s important to note that the choice of brand depends on various factors such as your specific requirements, budget, and the operational conditions in which the truck-mounted crane will be used.

2. Which brand of truck-mounted crane is good?

Selecting a truck-mounted crane isn’t simply a matter of determining which brand is superior. A truck-mounted crane is a modified vehicle and is composed of three main parts: the chassis of the vehicle, the crane itself, and the cargo box.
(1) The chassis of the vehicle can be sourced from manufacturers like Dongfeng, FAW, Foton, Sinotruk, etc.
(2) Popular crane machine brands include XCMG crane machine, Shimei crane machine, Dahan crane machine, and more.
(3) The cargo box is typically modified by enterprises with the necessary modification qualifications.
The choice of a good truck-mounted crane involves considering the quality and reputation of each component manufacturer, as well as the overall integration and performance of the assembled vehicle.

3. What certificates are required for the driver of a truck-mounted crane?

The driver of a truck-mounted crane is obligated to possess three essential certificates: a Class B driver’s license, an operation certificate for getting on the vehicle, and a professional qualification certificate. The driver’s license is commonly referred to as the off-vehicle certificate, while the operation certificate is known as the on-vehicle certificate.
These certificates ensure that the driver is qualified and legally authorized to operate the truck-mounted crane safely and in compliance with the law.

4. How long can the carriage of a truck-mounted crane be?

The carriage length of a truck-mounted crane varies depending on its capacity. 2-ton crane machines are usually installed on relatively small vehicle chassis, such as those produced by Dongfeng, including the Dongfeng Xiaobawang truck-mounted crane chassis and the Dongfeng Jinba truck-mounted crane chassis. The carriage size of 3-ton, 4-ton, and 5-ton truck-mounted cranes generally ranges from 3 to 6 meters. The length of the carriage for 5-ton, 6-ton, 8-ton truck-mounted cranes can typically be 5.8 to 6.1 meters. For 8-ton, 10-ton, 12-ton, and 16-ton truck-mounted cranes, the carriage length can extend to 7.5 – 8.5 meters.
It’s crucial to select the appropriate carriage length based on the specific tasks and payload requirements to ensure efficient and safe operation.

5. Are there any differences between a truck-mounted crane and a vehicle-mounted crane?

Yes, there are distinct differences. A truck-mounted crane, also known as a truck-mounted crane transport vehicle, represents a seamless combination of a freight vehicle and a crane. It enables both lifting and transportation in a single operation. In contrast, a vehicle-mounted crane refers to a lifting platform installed on an automotive platform but lacks the capability to carry goods. Its sole function is lifting and it is not designed for the transportation of goods.

6. Are there currently dump-type truck-mounted cranes?

Typically, standard truck-mounted cranes come equipped with regular cargo boxes and do not inherently possess the dump function. However, upon customization by the manufacturer of truck-mounted cranes, the dump feature can be incorporated. Naturally, in such cases, the strength of the cargo box also needs to be concurrently enhanced to withstand the additional stress and functionality.

7. In an 8-ton truck-mounted crane, does the “8 tons” refer to the maximum lifting weight of 8 tons or the limited load of 8 tons?

In an 8-ton truck-mounted crane, the “8 tons” indicates the maximum lifting weight it can handle.

8. What can a 3-ton truck-mounted crane haul?

A 3-ton truck-mounted crane finds applications in landscaping, small-scale construction sites, power companies, and similar settings. A 3-ton truck-mounted crane often features a powerful card blue-plate truck-mounted crane and can be equipped with a 2-ton or 3.2-ton straight-fold boom crane machine.

9. What does the boom section of a truck-mounted crane mean?

Truck-mounted cranes typically offer two types of booms: the folding boom and the straight boom. The straight boom can be further divided into two sections, three sections, four sections, five sections, and six sections. When not in use, all the boom sections can be retracted for convenience and storage.

10. How to select the slewing bearing for a truck-mounted crane?

Generally, the selection of the slewing bearing for a truck-mounted crane is based on the load-bearing curve. Firstly, the static safety factor is taken into consideration. Then, calculations are made for the maximum working load, axial force, and overturning moment. Finally, the static reference load of the slewing bearing is computed.

Now, let’s delve deeper into some additional aspects related to truck-mounted cranes:
When it comes to the maintenance of truck-mounted cranes, regular inspections of the crane’s mechanical components, such as the winch, pulleys, and cables, are essential. Any signs of wear or damage should be addressed promptly to prevent potential failures during operation.
The hydraulic system of the crane also requires frequent checks for leaks, proper fluid levels, and the functionality of valves and pumps. Contaminated hydraulic fluid can cause significant damage, so regular fluid changes and filtration are necessary.
In terms of safety precautions, operators should always ensure a stable and level working surface before operating the crane. Overloading the crane beyond its specified capacity is strictly prohibited and can lead to dangerous accidents and damage to the equipment.
When transporting the truck-mounted crane, it’s important to secure all components properly to prevent any movement or damage during transit. Special attention should be given to the boom and any loose attachments.
For those considering purchasing a used truck-mounted crane, a thorough inspection of the vehicle’s history, including maintenance records and any previous accidents or damage, is crucial. It’s also advisable to have a qualified mechanic assess the condition of the crane and its components.
The location and environment in which the truck-mounted crane will be used can also influence the choice. For example, if the crane will be operating in corrosive or extreme weather conditions, special coatings or protective measures may be needed to prolong the lifespan of the equipment.
Finally, staying updated with the latest industry standards and regulations regarding the operation and maintenance of truck-mounted cranes is vital to ensure compliance and safe operations.
In conclusion, understanding the various aspects of truck-mounted cranes, from their brands and components to their operation, maintenance, and safety considerations, is essential for making informed decisions and ensuring their efficient and safe use in various applications.
