XCMG 25T truck crane QY25K5A

Description:

QY25K5A is 25 ton XCMG truck boom, it is with QY25K5-I’s advanced model.

It is with 5 section boom and 1 lattice jib.

Main features:

1. It has 5 sections “U” shape boom, boom length 10.6 to 41m.

2. Insert type boom, effectively improve the lap length, boom deformation is small; embedded slider, support area, reduce the contact stress of the cylinder.

3. Nine gears, superior driving performance, climbing ability, climbing 40%, the maximum speed of 90km / h.

4. open quantitative pump variable motor system, the main use of dual-pump confluence to meet the requirements of user speed, effectively reduce energy consumption and system heat; independent research and development of load-sensitive systems, smooth operation, energy efficient; unique structure of the swing buffer Technology to achieve no jitters; the use of gravity reduction, effective energy saving, balancing valve using overload compensation technology to ensure a smooth decline in speed; large torque starting point of the new hydraulic variable motor to ensure that the second rise does not decline, effectively improve operating efficiency.

5. The national patent of the arm telescopic system, effectively avoid the misuse caused by the cylinder bending, boom broken, to improve the active safety of telescopic system.

6. Dual-mode mode engine, normal driving, the use of large power to ensure vehicle performance; on the train work with a smaller power, as much as possible to reduce fuel consumption.

7. equipped with torque limiter, with temperature control and backlight function dot matrix LCD color display can be clearly and intuitively text and graphics to show the crane operating parameters, so that a variety of conditions at a glance; with overload device to protect the safety of equipment ; With a high degree of limit, safety direction detection and other safety devices; and equipped with lighting device for easy night work; with a lifting balance valve, telescopic balance valve, variable balance valve, rotary buffer valve, hydraulic two-way lock, Type back to the system, and has a striking security signs to protect the safety of operations.

8. the use of the company's mature design concept, the use of INTRALINK design platform, Pore design software, analysis software, Adams simulation software design methods, the boom, turntable, frame, legs, power systems, transmission systems and other key components To analyze, to ensure the reliability of the design. 9, to take anti-error measures, electrical alignment by line number to prevent mistaken access. Choose the most common parts with active equipment, to ensure good maintenance of equipment.

9. the main performance parameters of the lifting device can be carried out state monitoring shows that the electrical system and hydraulic system to set the necessary test points (1. get off the multi-way valve pressure point; 2. return to the oil filter pollution Pump; low pressure alarm; 5 power part: engine speed, urea level display), easy to test and fault isolation. Equipped with vehicle tools and spare parts, easy to diagnose and repair common faults.
