Many builders, ATEK EOV-4421 excavators on KRAZ truck chassis are well known to utility workers, which was produced at the ATEK enterprise ("Red Excavator") in the 1980s-2000s. Many of these excavators are still working successfully on construction sites in the country.
It should be noted, that this excavator is a very reliable earthmoving machine, made according to the technologies and standards of the USSR and with a large resource. Also, many spare parts and aggregates of EOV were produced for this technique at one time, which allowed earlier and allows even now to maintain the constant performance of many excavators of this modification.
But now there is a certain problem with that, that this excavator has already been discontinued and is no longer in production. So, owners of this equipment should find a reliable supplier to maintain the operability of their excavator for a long time original spare parts of EOV, as well as find for sale and plan for the purchase of some basic hydraulic units, that directly affect the further performance of EOV-4421.
Among the large water nodes, Hydraulic specialists highlight the following, which should be paid attention to:
– Central collector type.
– powerful hydraulic double pump.
– Hydraulic platform rotation motor.
It should be noted, that in Ukraine there is a fairly common practice of purchasing such hydraulic units after major repairs. In connection with the very large operating resource of such units, this is a good opportunity for significant savings with almost no loss of resource, which must be used.
