What are the characteristics of heavy truck-mounted cranes?

Heavy truck-mounted cranes fall within the series of truck-mounted cranes with the largest lifting tonnage. The lifting capacity typically ranges from 20 tons to 260 tons and they are commonly employed to hoist large-scale equipment such as mechanical devices and oil tanks. The forms of these cranes encompass front-mounted and rear-mounted options and they can be utilized in various configurations like semi-trailer truck-mounted cranes, flatbed truck-mounted cranes, cargo box truck-mounted cranes, and more. So, what are the distinctive features of heavy truck-mounted cranes, ranging from performance to design? Let’s delve into some aspects of heavy truck-mounted cranes together.

All components of heavy truck-mounted cranes are fabricated from high-strength steel plates with a yield strength of 78.5 kilograms per square millimeter. For instance, a 12-millimeter-thick high-strength plate possesses the equivalent strength of a 30-millimeter-thick manganese plate. Welds undergo thorough flaw detection inspections, and structural components are precisely processed on large-scale machine tools. This ensures the integrity and robustness of the crane’s structure, capable of withstanding heavy loads and demanding working conditions. The use of high-strength materials not only enhances the load-bearing capacity but also contributes to the overall durability and reliability of the crane.

a. All accessories of the hydraulic control system are sourced from original European factories. This ensures that the actions are highly sensitive and the performance remains stable, safeguarding the safety and reliability of the entire hydraulic system. The precise and responsive control provided by these high-quality components is crucial for accurate and smooth lifting operations, minimizing the risk of accidents and maximizing operational efficiency.

b. The optimized slewing mechanism incorporates high-quality reduction gears from Chinese-foreign joint ventures and imported buffering devices. The hydraulic motor adopts an ultra-large torque, enabling the crane to handle heavy loads with ease during rotation and positioning. This combination of advanced components and optimized design ensures smooth and stable slewing movements, enhancing the crane’s overall performance and operational flexibility.

c. Professional cylinder manufacturers supply specialized cylinders, instilling greater confidence in users during operation. The quality and performance of the cylinders are critical for the safe and effective lifting and extension of the crane’s boom, and the use of reliable cylinder products contributes to the overall reliability and longevity of the crane.

a. Comprehensive quality inspection reports are provided for steel materials, hooks, and structural components. These include steel material quality inspection reports, hook quality inspection reports, cylinder pressure-holding tests, and in-plant quality inspection reports for structural components. This ensures that all critical components meet strict quality standards and performance requirements, minimizing the risk of failure or malfunction during operation.

b. Repeated tests are conducted to ensure the highest quality. Every crane undergoes full-load tests to verify its performance and stability under maximum working conditions. This rigorous testing process helps identify and address any potential issues before the crane is delivered to the customer, ensuring that it is fully capable of meeting the demanding requirements of heavy lifting tasks.

a. The upper vehicle operation seat and sunshade are designed to provide customers with a more comfortable and ergonomic experience. This reduces operator fatigue during extended periods of operation, enhancing productivity and safety. Thoughtful design elements such as proper seating support, adjustable controls, and protection from the elements contribute to a more pleasant working environment.

b. Installation of spotlights and warning lights enhances operational safety, especially during low-light or complex working conditions. These lighting fixtures improve visibility for the operator and alert others in the vicinity, reducing the risk of accidents and ensuring safe operations in various environments.

The surface of the heavy truck-mounted crane undergoes sandblasting and low-temperature baking paint treatment. This process ensures strong paint adhesion, a smooth finish, and long-lasting durability. The paint not only provides aesthetic appeal but also protects the metal surface from corrosion and wear. Hydraulic pipe fittings and hardware are all heat-treated to enhance their strength and durability, making small parts more refined and resilient. The rational layout of the oil pipes contributes to a tidy and organized appearance while also facilitating maintenance and inspection.

With the continuous development and expansion of the country, numerous major construction projects rely on the use of heavy truck-mounted cranes. The demand for these powerful and reliable lifting machines is expected to remain strong in the foreseeable future. Their ability to handle large and heavy loads makes them indispensable in sectors such as infrastructure building, industrial installation, and energy development. As technology progresses and design improvements continue, heavy truck-mounted cranes will likely become even more advanced, efficient, and safe, further solidifying their position in the heavy equipment market.

In conclusion, heavy truck-mounted cranes boast a combination of robust structure, reliable performance, strict quality control, user-friendly design, and aesthetic appeal. These characteristics not only meet the current needs of various industries but also position them well for continued growth and development in the future.
