In fields such as engineering construction, logistics transportation, and urban operation and maintenance, the "multifunctionality" and "flexibility" of equipment often directly affect operational efficiency and cost control. As a special vehicle that integrates lifting and transportation functions, the mobile crane (referred to as "mobile crane") has become a convenient choice in many scenarios due to its core advantage of "one vehicle for multiple uses". It organically combines the crane with the chassis of the cargo truck, which not only has the cargo transportation capacity of ordinary trucks, but also can complete cargo loading and unloading, equipment lifting and other operations through its own lifting device, without the need to call for additional lifting machinery, greatly simplifying the operation process and reducing comprehensive operating costs.
The convenience of truck-mounted cranes essentially stems from their integration of the two core needs of 'transportation + lifting'. In traditional operation modes, if equipment or goods need to be transported from location A to location B and then lifted, it often requires coordinating two devices: a cargo truck and a mobile crane. This involves two dispatches and two operations, not only increasing labor and time costs but also potentially affecting efficiency due to site restrictions and poor equipment coordination. In contrast, a truck-mounted crane can complete 'load and lift immediately upon arrival' with just one device, making it particularly suitable for scenarios with narrow sites and dispersed work points. For example, in building material delivery in rural areas, it can transport steel bars and cement to the construction site and directly lift them to the designated floor; in power repair operations, it can quickly transport repair equipment and lift it into place, saving precious time for repairs. This 'integrated' operation mode gives it significant advantages in efficiency, cost, and flexibility.
Truck-mounted cranes have extremely wide application scenarios. Equipment with different lifting capacities and boom lengths can meet various operational needs ranging from light to heavy. The following are several typical working conditions:
（1） Engineering construction and infrastructure field
In the construction of small and medium-sized projects, gantry cranes are indispensable auxiliary equipment. For example, in municipal road maintenance, it can be used to lift components such as curbstones, manhole covers, and small streetlight poles; Responsible for transporting and hoisting scaffolding, small prefabricated components, decoration materials, etc. during the early or final stages of building construction. For small-scale infrastructure projects in remote areas, such as rural road and bridge construction, the on-board crane does not need to rely on the transportation and entry conditions of large lifting equipment, and can independently complete the transportation and lifting of steel bars, templates, and small prefabricated parts, greatly improving construction convenience.
（2） Logistics and loading and unloading field
In logistics transportation, on-board cranes are particularly suitable for loading and unloading large or scattered goods from door to door. For example, in furniture and home appliance distribution, goods can be directly lifted from the warehouse onto the vehicle, transported to the destination, and then lifted into the household without relying on the receiving party's loading and unloading equipment; In the transportation of industrial raw materials, such as steel, pipes, equipment accessories, etc., an integrated operation of "transportation+loading and unloading" can be achieved between factories, warehouses, and construction sites, reducing the transfer of goods, lowering the risk of cargo damage and transportation costs. In addition, for short distance transshipment at ports and docks, on-board cranes can cooperate with large ships to complete the connection and transfer of small and medium-sized goods, making up for the lack of flexibility of large lifting equipment.
（3） Urban operation and emergency rescue
In daily urban operation and maintenance, the flexibility of on-board cranes makes them a "good helper" for multiple scenarios. Used for transplanting trees, lifting large flower pots or landscape stones in landscaping operations; In power and communication emergency repairs, quickly hoisting transformers, power poles, communication base station equipment, etc. can shorten the repair time; In the maintenance of municipal pipeline networks, lifting pipelines, manhole covers, repairing equipment, etc. In emergency rescue scenarios, such as earthquakes, floods, and other disasters, the on-board crane can be used to clear debris, lift rescue equipment, and transfer trapped personnel or materials. Its "ready to use" feature can save critical time for rescue.
（4） Agriculture and Rural Applications
In agricultural production and rural construction, the practicality of on-board cranes is equally prominent. For example, in the transportation of agricultural products, bulk agricultural products such as grains, fruits, vegetables, etc. can be lifted onto trucks or lifted from transport vehicles to warehouses; In agricultural facility construction, steel frames and glass are used for hoisting when building greenhouses, or equipment such as water pumps and pipelines are used for hoisting when constructing agricultural water conservancy facilities; In rural housing construction, transporting and hoisting building materials such as bricks, tiles, cement, prefabricated panels, etc. is particularly suitable for rural areas lacking large-scale hoisting equipment to reduce construction costs.
Selection is key to maximizing the value of truck-mounted cranes. It requires combining actual operational needs and comprehensively considering multiple dimensions to avoid 'using a big crane for a small job' or 'a small crane trying to do a big job'.
（1） Clear homework requirements: tonnage and arm length are the core
Firstly, the tonnage and arm length of the crane need to be determined based on the maximum weight and maximum operating radius of the daily lifting of goods. For example, if the main lifting load is 3-5 tons of goods with a working radius of 8-12 meters, choosing a 5-8 ton truck mounted crane can basically meet the needs; If heavy equipment weighing more than 10 tons needs to be lifted and the operating radius is large (such as 15 meters or more), it is necessary to choose a tonnage of 12 tons or more and match it with a longer lifting arm (or telescopic arm). It should be noted that the "rated lifting capacity" of the crane will decrease with the increase of the operating radius, so the selection should be based on the "rated lifting capacity at the maximum operating radius" as the core reference, rather than just looking at the maximum tonnage. For example, a 10 ton truck mounted crane can lift 10 tons at a close range of 3 meters, but may only be able to lift 3 tons at a radius of 10 meters, which needs to be calculated based on actual working conditions.
（2） Choose the appropriate chassis: the load and power need to be matched
The chassis is the "carrier" of the on-board crane, and its load-bearing capacity and power performance directly affect the stability and operational efficiency of the equipment. The tonnage of the chassis needs to match the tonnage of the crane. Generally, the larger the tonnage of the crane, the stronger the required load-bearing capacity of the chassis (such as an 8-ton crane that requires a chassis of 12 tons or more), to avoid safety hazards caused by chassis overload. In terms of power, if you frequently work on complex road conditions such as mountainous areas and hills, you need to choose a more powerful engine (such as a high-powered diesel engine) and a suitable gearbox (such as automatic transmission or with climbing gear); If driving mainly on urban roads, it is necessary to balance power and fuel consumption, while paying attention to whether the chassis size complies with urban traffic restrictions (such as height, width, wheelbase, etc.). In addition, the configuration of the chassis cab (such as single row, half row, double row) also needs to be selected according to the number of operators, and the double row cab is suitable for scenarios that require multiple people to work together.
（3） Focus on core components: reliability determines service life
The core components of the on-board crane, such as the hydraulic system, slewing mechanism, and boom, directly affect the reliability and safety of the equipment. The hydraulic system is the "power source" for lifting operations, and it is necessary to choose equipment that uses well-known brands of hydraulic pumps, hydraulic valves, and oil cylinders to ensure stable operation of the hydraulic system and reduce faults such as leakage and jamming; The slewing mechanism determines the operational flexibility of the crane, and attention should be paid to its slewing speed, smoothness, and braking performance, especially in scenarios with frequent slewing operations (such as logistics loading and unloading). A reliable slewing mechanism can improve efficiency; The material of the crane boom is usually high-strength alloy steel, and its thickness, welding process, and bearing capacity need to be confirmed to avoid affecting lifting safety due to material issues.
（4） Considering the homework environment: adaptability is key
Different work environments have different requirements for on-board cranes. If working on muddy and rugged construction sites, it is necessary to choose a chassis with stronger off-road performance (such as four-wheel drive chassis, large tread tires), and ensure that the ground clearance of the equipment is sufficient to avoid chassis scratches; If working in flammable and explosive environments (such as oil fields and chemical sites), explosion-proof on-board cranes should be selected, equipped with explosion-proof motors, explosion-proof hydraulic components, etc., to meet safety regulations; If working in cold regions, it is necessary to pay attention to the low-temperature starting performance of the equipment, choose engine oil and hydraulic oil suitable for low-temperature environments, and equip preheating devices to ensure the normal operation of the equipment at low temperatures.
（5） Balancing brand and service: after-sales support cannot be ignored
Choosing a brand with good reputation and high market share ensures better quality and stability of its equipment. At the same time, attention should be paid to the manufacturer's after-sales service network, such as whether there are service stations near the work area and whether the supply of accessories is timely. As a special equipment, the maintenance and replacement of accessories are crucial for the on-board crane. Comprehensive after-sales service can reduce equipment downtime and lower operating costs. In addition, it is necessary to confirm whether the manufacturer provides operational training, technical support, and other services to help operators quickly master equipment usage skills and improve operational safety and efficiency.
Truck-mounted cranes, with their unique advantage of 'multi-functionality in one vehicle', have become an important bridge connecting transportation and lifting operations. They continuously demonstrate their convenience and practicality in various industries. When selecting a model, it is necessary to take actual operational needs as the core, comprehensively consider factors such as tonnage, boom length, chassis, core components, and working environment, while also taking into account brand reputation and after-sales support, in order to select the most suitable equipment and maximize its value. With the continuous advancement of technology, truck-mounted cranes will develop towards being more intelligent, efficient, and environmentally friendly, providing stronger support for the upgrading of operational models in various industries.
