PY160C motor grader for Road Construction with Easy Operation
Product Introduction
PY160C motor grader is a new model that Tiangong has improved its structure on the basis of PY160B grader. The main performance parameters of this machine are advanced, and the work is reliable. Articulated frame, with No-spin differential, has reached the highest level of similar products in the world. It is suitable for large-area ground leveling, trenching, slope scraping, bulldozing, loosening, and snow removal in roads, mines, airports, and farmland. Waiting for work. It has greatly improved the hydraulic system, operating device, appearance, driving comfort, etc., and improved the performance and reliability of the product. It is an important working machine for mechanized construction at home and abroad.
Product Features
1. Shangchai 6135K-10a, Weichai WD615 series, Dongfeng Cummins 6BTA5.9 various engine configurations.
2. Single-plate dry friction clutch. Cylindrical helical gear constant mesh fixed shaft transmission, gear engagement, mechanical shifting, composed of two parts of the main transmission, the main transmission has a first gear, second gear, direct gear and reverse gear, and the auxiliary transmission has two gears, low speed and high speed. Make the machine have the speed of six gears forward and two gears backward.
3. The front axle is a steering driven axle with a maximum steering angle of 50 . The mountain-shaped bridge frame is welded by steel plates. Front-wheel can respectively tilt 18 to left and right as required. .The rear axle is composed of bridge body, guide plate, bracket and main drive, which can rotate freely relative to the bracket, so as to realize the overall steering of the rear axle; the balance box is a chain drive, and the driving sprocket and the half shaft are welded together.
4. Two independent circuit systems make the blade lifting cylinders at the left and right ends operate at the same lifting speed at the same time, which improves the operation performance and production efficiency of the motor grader; the multi-way valve adopts an integral type, which reduces pressure loss and improves To ensure the reliability of the seal; the hydraulic system adopts a closed oil tank, and the breather valve maintains a constant pressure in the oil tank, which helps the oil pump to absorb oil and reduces the risk of cavitation. At the same time, the closed oil tank prevents foreign matter from entering the oil tank and causing pollution Hydraulic system, the hydraulic system uses L-HM32 anti-wear hydraulic oil.
5. The front wheel steering system adopts load-sensing full-hydraulic steering device, which is composed of gear pump, priority valve, and load-sensing hydraulic steering unit. Its advantage is that it can preferentially distribute flow to the steering oil circuit .Regardless of the load pressure and the speed of the steering wheel, sufficient oil supply can be guaranteed. Therefore, the steering action is stable and reliable. The pipeline joints of the hydraulic system adopt the double sealing form of the cone surface and the “0″ ring, which significantly reduces the number of pipelines. The leakage phenomenon at the joint improves the sealing performance of the hydraulic system.
6. There are operating devices such as blades and rippers, all of which are connected to the traction frame. The traction frame adopts a box-section welded structure. The rod is hinged, and with the help of coordinated actions such as blade lifting cylinder, blade tilting cylinder, blade leading cylinder and slewing ring, various working states of the blade and ripper can be realized. Since the slewing ring can rotate 360 degrees, the installation The ripper on the slewing ring can work in the front and rear directions, and can also be drawn together with the traction frame to further expand the loosening range.
