What and how ? Hydromotors for the rotation of smaller construction machines are much less complex than those of larger models. There are two most popular types of hydraulic motors used to drive the rotation of smaller construction machines. These are piston and rotary engines, so-called “rotators”. How do you recognize if the swing motor
Due to the influx of a large number of driving engines of construction machinery other than excavators. I decided in a short article to describe their principle of operation and whether it can be properly regenerated. So to restore their efficiency at a much lower price than associated with the purchase of a new engine.
The use of planetary gears in other construction machinery. The planetary drive train is used in a very wide range of construction machinery. In principle, all machines moving on caterpillars are driven by a hydromotor transmitting power to the planetary gear. In our opinion, these types of gearboxes are the best way to change the
Did you forget Many owners, operators of mini diggers forget about servicing their machines in the winter. In 99% of cases, smaller mini diggers are not as necessary to work as in the summer because they are not strong enough to overcome the permafrost layer, so remember that that winter is the only time when
Planetary gear: What is it and what is it for? Travel final drive planetary gear is a drive wheel that is used in planetary propulsion transmissions. Depending on the construction, there are: one, two or three rows of satellites (driving gears). Each row has 2 to 5 gears. Rows of satellites are counted from the
Final drive housing repair of JCB excavator Cracked casing, mounting ring in final drive, flange in JCB machine. For a long time we have observed a problem with cracking housings, hydromotor mounting rings of JCB excavators. Housings break most often on models 8016, 8025, 8045, 8060. Description of the problem The reason for this damage
CAT travel gearbox repair CAT 325 is quite a popular machine. Therefore, we decided to describe the process associated with its repair and the problem associated with the device’s factory defects. How does CAT travel gearbox repair look like? Learn more by reading the article below! Of course, the process of travel final drive repairing,
Bearings of travel final drive usually are angular contact which task is to minimize the friction resistance during work of the planetary gearbox Bearings installed in excavators of 1.5-50 tone weight are usually divided into two types: tapered roller bearings and angular contact bearings The angular contactor bearing is constructed in such a way that
