Lifting Capacity

• The lifting capacity of truck-mounted cranes covers a wide range, from a few tons for light-duty ones to dozens of tons for heavy-duty ones. Small truck-mounted cranes usually have a lifting capacity of around 3 to 5 tons. They perform excellently in scenarios such as urban logistics distribution and small building renovation, and can easily lift relatively light goods like small mechanical equipment and bagged building materials. Medium-sized ones generally have a lifting capacity in the range of 8 to 15 tons, which can handle the lifting tasks of medium-sized prefabricated components and some industrial equipment. As for large truck-mounted cranes, their lifting capacity can reach 20 tons or more. For example, in large engineering projects such as bridge construction and the installation of equipment in large factories, they can lift overweight objects like bridge girders and large reactors, fully meeting the requirements of heavy-duty lifting operations.

• Its lifting capacity is affected by multiple factors in an integrated manner. The material and structural form of the boom are of crucial importance. The boom made of high-strength alloy steel can reduce its own weight while ensuring strength. Moreover, reasonable structural designs such as box-shaped and truss structures can better bear the pulling force of heavy objects. The performance parameters of the winch, such as the rated pulling force and the rope capacity of the drum, directly determine how heavy and how high an object it can lift. Whether the counterweight layout of the whole vehicle is reasonable is also related to the lifting capacity. Appropriate counterweights can balance the moment generated when lifting heavy objects and prevent the vehicle from tilting forward. In addition, the pressure magnitude and the flow stability of the hydraulic system affect the power transmission of each movement, providing stable and reliable power support for the lifting operation and ensuring that the crane can work safely and efficiently within the rated lifting range.

Lifting Height

• The range of lifting heights is relatively wide, generally varying from several meters to dozens of meters. The lifting height of an ordinary truck-mounted crane may be around 10 meters, which can meet the needs of lifting goods to a certain height in most conventional logistics loading and unloading, low-rise building construction and other scenarios. For truck-mounted cranes used for high-rise building construction, large equipment installation and other special purposes, the lifting height can reach 30 meters or even higher, enabling them to lift heavy objects to higher positions and expanding the vertical space range of operations.

• The lifting height is mainly affected by the length and number of sections of the boom as well as the performance of the lifting mechanism. The telescopic boom can effectively increase the lifting height by adding extended sections. Moreover, different lifting speed gears are set, which also facilitates operators to flexibly adjust according to the actual lifting situation.
