When choosing a truck-mounted crane, most users have always preferred knuckle boom cranes.
Knuckle boom cranes are flexible to operate, occupy little space, and can extend and retract their booms under load, making them very popular in urban construction and confined space operations.

In contrast, while traditional straight-boom truck cranes have a simple structure and high load-bearing capacity, their extension mechanism typically relies on wire rope traction.
Due to the tensile limits of wire ropes, straight-boom cranes cannot extend their booms under load.
This means that the boom must be fully extended before lifting operations can begin, significantly increasing the space required for operation and limiting the flexibility of the work site.
To overcome this limitation, we have launched the all-new Model 515 5-ton straight boom truck-mounted crane. The biggest highlight of this crane is the hydraulic telescopic design of the second and third boom sections. This innovative design allows the straight boom crane to extend its boom while under load, significantly improving work efficiency and space utilization. Whether in confined construction sites or in situations requiring precise lifting, the Model 515 crane can easily handle the demands.

Main advantages
- Hydraulic extension boom under load:
The hydraulic extension mechanism of the second and third boom sections allows the boom to extend and retract under load, avoiding the limitation of traditional straight boom cranes that must extend the boom when unloaded, and greatly saving working space.

- High load capacity
As a 5-ton truck-mounted crane, the 515 model maintains the high load capacity of the straight boom structure while ensuring flexibility, meeting the lifting needs of small and medium-sized projects.
- Easy to operate
The hydraulic telescopic boom, combined with an intelligent control system, allows operators to easily control the extension speed and angle, reducing operational difficulty and improving work safety.
- Suitable for multiple scenarios
Whether it is a construction site, a dock, or a city delivery or installation project, the 515-type straight boom crane can provide efficient and precise lifting services, greatly expanding the application range of straight boom cranes.
The introduction of the Model 515 truck-mounted crane not only solves the problem of limited working space for traditional straight boom cranes, but also provides users with a brand-new option that combines high load capacity, high efficiency, and convenient operation. It elevates the potential of straight boom cranes to a whole new level, making more construction scenarios more flexible and efficient.
