  1, idle automatically forward, put into forward gear can also be normal driving, put into backward gear when the machine stops, can not walk. The working pressure of each gear is normal.   Failure causes. Forward clutch master and slave plate sintering and clamping. Forward clutch piston jamming, support check valve blockage.   Removal method. Disassemble the forward clutch, clean the oil channel, replace the main and driven friction plate and related damaged parts, clean the relevant parts, replace the outer seal ring, clean and unclog the check valve, replace the clutch friction plate, inner and outer seal ring.   2, the whole machine suddenly does not move forward, not backward, variable speed working pressure is normal.   Cause of failure. (1) for the variable speed distribution valve failure or (40F, 50D, 50F) accumulator damage variable speed valve pneumatic control valve stem stuck or damaged. (2) the oil feed path blocked. (3) Accumulator oil circuit blockage. (4) Pneumatic c

China as a large infrastructure country,   construction machinery   can be seen everywhere, but in the end which is a bulldozer, which is a forklift, not necessarily everyone can distinguish clearly, in order to let you better understand the various construction machinery,   HBXG   share this article with you today!   1、Bulldozer Bulldozer is a kind of earthwork machinery capable of excavating, transporting and discharging rock and soil, which has a wide range of uses in open pit mines. It is used for building discharge yards, leveling car discharge yards, stacking scattered ore rocks, leveling working flat pans and building sites, etc.   2、Earth grader Earthmoving machinery that uses scrapers to level the ground. The scraper is installed between the front and rear axle of the machine, and can lift, tilt, turn and stretch out. The action is flexible and accurate, easy to manipulate, and has high precision in leveling the ground. It is suitable for constructing road base and road surfac

Bulldozers   are one of the most common types of earthmoving equipment and are used in a wide variety of projects due to their simple construction and versatility. Take a look at the evolution and development of the bulldozer with   HBXG .   The world's first bulldozers? The bulldozer actually existed long before the invention of the steam engine, although it could not be considered a real machine, as it was powered by a horse-driven bulldozer plate to carry out the bulldozing function.   The world's first bulldozer. ●The true tracked bulldozer was a steam bulldozer designed by Benjamin Holt and Daniel Best for agricultural use in 1890.   ●Then, after a brief period of glory, the steam engine era was quickly replaced by the diesel engine. However, the prototype tracked bulldozer invented by Benjamin Holt survived. 1904 saw the introduction of Holt's first tracked bulldozer. 1906 saw the introduction of Holt's first diesel-powered tracked bulldozer. 1915 saw the Allies u
