The failure of the excavator to hold the excavator is a frequent failure problem of the excavator. After all, the construction environment and high load working intensity of the excavator determine that such common actions are prone to failure.
Hydraulic pump
The excavator hold up is usually caused by the decrease of engine power. It is necessary to reduce the power demand of the hydraulic pump. You can adjust the adjuster nut of the pump. After adjustment, the excavator hold up phenomenon will generally be improved. However, you will find that the excavator will slow down and its strength will be weak, so this method will not cure the symptoms but the root cause.
Engine problems
It can also increase the power of the engine. In many cases, problems with the diesel pump cause the engine power to drop, sometimes accompanied by the phenomenon that cold excavators are easy to start and hot excavators cannot start. At this time, as long as the oil pump is calibrated and the plunger nozzle is replaced, the problem can usually be solved.
Diesel quality
Many drivers mentioned that the filter screen is blocked, the oil circuit is blocked, the oil tank has too many impurities, and the engine power is reduced due to too much impurities in the oil. Generally, the quality of oil provided by private gas stations or construction sites and oil trucks is relatively poor. Long term use of such oil will not only damage the machine, but also be the biggest source of holding up the truck. Therefore, we suggest that you must choose a regular oil supply channel.
Because the excavator is very harmful when holding the vehicle, it will affect the engine and hydraulic pump. Therefore, correct analysis of the causes of excavator failures and timely treatment, as well as strengthening the maintenance of excavators, are the premise to ensure efficient and safe work of excavators, which should be given full attention in actual work.
