Main Features:
1. Novel industrial design: European apical company designs series products of red star. This products feature novel appearance, hold holistic sense, and show international fashion. Besides advanced punching mould and electrophores is process improve elaborate manufacture.
2. Powerful lifting capacity: Boom embodies overseas or domestic low-alloy high-tensile structural steel and great-circle hexagnoal section, and has good neutral position and strong lifting capacity. Besides big span outrigger has good stabilization.
3. Efficient working performance: Single line pull is large, hoist speed is rapid, and single line speed is 125-135m/min due to double hoist variable motor design. Manipulation is precise, brake is stable, and work stabilization is advanced due to unique rotary cushion design.
4. One-up overlength main boom: Overtake main boom length and lead hoist height. Full extension length of QY25C main boom is 33.5m,and maximum hoist height is 33.9m.
5. Superexcellent traveling performance: Powerful engine and reliable chassis systemmake Sany truck crane hold superexcel lenttraveling performance.
6. Precise control system: Limited moment control system is made up of Sany, which merges microelectronic technique intelligent malfunction dagnosis, and dynamical monitor technique. It made the equipment working more safty and efficiency.
7. Excellent ECC system: ECC control and manage system is the original technique of domestic engineering machine, which determines the location with GPS, helps the customer master the vehicle location and working condition, and realize the vehicle management and malfunction diagnose real time.
8. Strong service: Relay on strong service management of Sany group. extend country-wide 6S service point: take the concept of exceeding industry standard and customer expection, and provide oriental service.
Structure
 |
Cab
It is made up of anti-corrosive steel plate, with streamline and full-width type, wide visul field, and elaborate structure. The interlayer safety glass is selected for the front windfield, with the full-sealed intenerated decorative element inside the cab. With heating and defrosting device and air conditioning system, it makes operators confortable, in addition, it has immproved the reliability and security of driving. | |
 |
Power System
It characterized by oil saving, advanced design, and superior manufacture. It has made oil consumption 20% lower than that of domestic similar products. | |
 |
Boom System
The main boom is made up by hexagonal section boom sleeve, additionally, as the finite element analysis is adopted, the reasonable design and commpacted structure has been guaranteed. The boom is of rational joint, and it is of the advanced bearing capacity in China. | |
 |
Hydraulic System
The cartridge inserted valves(USA VICKERS) are selected as electromagnetic valves of the controlling oil circuit, as they are designed in combination of the leading control valve, it is characterized by flexible action as well as stable and reliable performance,and it has also provided protections to numerous combined working conditions. | |
 |
Slewing&Hoisting System
The planet gear deceleration device and normally closed brake is taken for the slewing mechanism, in addition, the rotary cushion valve for special purpose is equipped to ensure a stable slewing.and, it is of good inching capability. The stepless shifting is achieved in the main and auxiliary hoisting mechanisms,and, it is of high efficiency, large shifting ratio, and reliable working performance. | |
 |
Chasis&Electric System
Optimal chassis design leads to smooth power shifting. | |
