The operations of this 25 ton mobile crane QY25K5A are very simple, convenient and flexible. Mobile crane QY25K5A is widely used forlifting operation and installation work in urban renewal, transportation, ports, bridges, oil field,industrial and mining enterprises, etc.
1. U-shaped cross-section boom has small depth-width ratio, strong bearing capacity, small deformation, strong anti-bending and powerful lifting capacity. The main boom length is 10.6 m to 41.0 m, the performance of mid-extended boom and fully-extended are also superior.
2. Plug-in boom head effectively increases the boom connect length and reduces boom deformation. Embedded sliders are equipped, which enlarge the contact square and reduce the contact stress of boom.
3. With 9-speed transmission equipped, it has superior travel and grade ability. The max.grade ability is 40%, max. travel speed is 90 km/h.
4. Particular slewing technology realizes smooth slewing and no jitter. Free fall is adopted in the elevating system, which
effectively realizes energy-saving.
5. Equipped with new hydraulic variable displacement motor with large original torque to ensure no gliding during second-lifting, improve working efficiency.
6. The boom telescoping system had obtained Chinese patent, effectively prevent occurrence of telescoping cylinder bending and boom broking cause by mis-operation, and therefore operation safety is improved.
7. The arrangement of jib stowed under boom is designed to facilitate operations in confined space, which is suitable for
applications in southeast Asian countries.
8. Duplex mode of the engine working condition, uses higher power during normal driving to ensure the driving performance of the vehicle, uses less power when working on the super structure as much as possible to reduce fuel consumption.
9. The main performance parameter of the lifting can be monitored and displayed, the necessary test points are set in the
electrical and hydraulic system, to facilitate testing and fault isolation. With attendant tools and spare parts, ease for common fault diagnosis and repair.
