Zoomlion QY16H431 Truck Crane
main feature
First, the appearance of coordination, color appearance, outstanding and become a classic small tonnage models.
Second, the chassis driving system
Use a dedicated chassis made by the driver, 6×4 drive. The main features are as follows:
1, using a low-mounted full-head cab, metal welding structure, soften the interior, has a good silencer function. Electric windows and doors, window washing device, luxury instrument work bench, warm air defrosting device and single-cooled air conditioner.
2, get off the full coverage of the platform, beautiful and practical.
3, matching Weichai or Shangchai engine, strong power.
4. Single-plate dry clutch, oil-controlled air-assisted movement, advanced structure, reasonable design and easy operation.
5. The mature “Dongqi†Dongfeng gearbox, transmission shaft and front axle are selected for low maintenance cost, and the bridge has automatic adjustment gap function.
6. Integral power steering gear is easy to maintain, safe and reliable.
Third, the lifting system
1. The large round hexagonal cross section boom optimized by the advanced software ANSYS is made of high strength steel, which has strong resistance to torsion and bending. The unique design of the large circular-arc boom slide support form (acquired national patent) has more uniform stress distribution, strong bearing capacity, and convenient adjustment. The local stiffness at the support point of the jib is good, and it is not easy to deform, and the equivalent plate thickness is increased. The lifting capacity of the arm achieves a lighter, stronger, and heavier weight target.
2, get off the use of double-sided control mechanism, convenient and practical operation. With a unique double throttle mechanism to save energy (patent number: ZL200420069265.9)
3, single cylinder amplitude, stable and reliable.
4. External meshing slewing mechanism facilitates maintenance and repair. Cycloid pin wheel reducer can absorb shocks and work smoothly.
5, the main hoisting belt with free fall, saving energy, improve efficiency.
6. The hydraulic system adopts a load feedback system controlled by a fixed differential pressure valve to achieve full manual proportional control. The triple uses a triple gear pump compound oil circuit, and all actions such as lifting, luffing, telescoping, and turning can be freely combined. Micro-motion is good. State-of-the-art hydraulic components ensure high reliability hydraulic system hydraulic system
7, rotary mechanism with free slip function.
8, on the car can control the chassis start and flameout, easy to operate and reduce fuel consumption.
9. The gas system is equipped with a dryer, which greatly improves the reliability of the gas system.
10, large volume toolbox, user-friendly.
Fourth, safety devices
The safety device is complete, the hydraulic system has a variety of relief valves, to suppress the abnormal high pressure in the circuit, to prevent damage to the hydraulic oil pump and motor, and to prevent the system in an overload state; wire rope over-discharge protection mechanism; height limit device; leg lock device Angle indicator, automatic torque limiter function and display content are more perfect, making the operation more secure.
