Product Description

QY25K-II truck crane is the product with high reliability inheriting X classical and advanced technology about design and manufacture truck crane of many years and based on mature technology.

Special truck crane chassis designed and manufactured by our company, all covered working surface and classic K-series appearance outline are equipped.

The operations of crane are very simple, convenient and flexible. It is widely used for lifting operation and installation work in urban renewal, transportation, ports, bridges, oilfield, industrial and mining enterprises, etc.
Advantages and highlights:

1. Bi-hexagonal 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 10.7m to 34m, completely surpassing its rivals with excellent lifting capacity. Steel plate for main boom is BS700MC, lifting performance of fully-extended boom improves 10~20%, exceeding its rival 1~7%.
2. Plug-in boom head effectively increases the boom connect length and reduces boom deformation.
3. It has superior travel and grade ability. The max. grade ability is 40%, max. travel speed is 80km/h.
4. Open fixed displacement pump and variable displacement motor system is adopted. The load sensitive system that researched and developed by ourselves contributes to smooth operation, high efficiency and energy saving. High pressure variable displacement motor contributes to light load with high speed and heavy load with low speed.
5. The boom telescoping system of had obtained Chinese patent, effectively prevent occurrence of telescoping cylinder bending and boom broking cause by mis- operation, and therefore operation safety is improved.
6. Duplex mode of the engine working condition, uses less power when working on the superstructure as much as possible to reduce fuel consumption.
