In the construction engineering, road construction, municipal renovation and other industries, excavators have always been an indispensable main equipment. With the increasing market demand for cost-effective equipment, second-hand excavators have gradually become the first choice of many engineering contractors due to their cost advantages and stable performance. So, how to improve work efficiency by using second-hand excavators? This article starts from the actual use of users and combines experience sharing to bring you a comprehensive answer.
If you need to buy or wholesale second-hand excavators, you can contact Bangxin second-hand excavator supplier through the email alexmachaoqun@gmail.com, or visit our website: https://www.bx-usedexcavator.com
Before using a second-hand excavator, the first task is to select the model. Different construction environments have different requirements for the tonnage, arm length, working radius, etc. of the excavator:
Working Conditions | Recommended Excavator Tonnage | Feature Description |
Municipal community construction | 3-8 tons | Flexible and easy to transfer |
Basic earthwork | 13-20 tons | Strong power and large operating range |
Crushing and demolition engineering | More than 20 tons | With hydraulic hammer, suitable for high-intensity construction |
In the process of improving efficiency, the stability of the equipment itself is crucial. The following are common inspection points:
Engine operating conditions: whether the cold start is smooth, whether there is any abnormal noise or black smoke
Hydraulic system: observe whether the operation is smooth and whether there is any oil leakage
Chassis walking mechanism: whether the track tightness is normal and whether it is offset
Cockpit control system: whether the joystick and display panel are sensitive
Operation technology directly affects equipment efficiency and service life. Experienced operators usually:
Use the "fast action + steady rhythm" construction method to reduce idling time
Reduce frequent start and stop to extend engine life
Proficiently use compound actions (such as rotating and retracting the arm at the same time)
Different operation modes can optimize construction efficiency in combination with site characteristics:
Operation mode | Small tips to improve efficiency |
Earth excavation | Use the "layered excavation + digging and rotating" mode to reduce reversal time |
Loading operation | Set the best loading angle to reduce the empty travel between the vehicle and the machine |
Leveling the site | Use the bucket reverse buckle method to improve accuracy and operation speed |
Efficient use is inseparable from daily maintenance. Second-hand excavators should pay special attention to maintenance to extend their service life:
Maintenance cycle | Maintenance items |
Daily | Check hydraulic oil, engine oil, and water tank levels |
Weekly | Clean air filter and check lubrication points |
Monthly | Replace oil filter and fully lubricate |
Every 500 hours | Replace hydraulic oil, hydraulic filter, fuel filter, etc. |
Implement a shift system to avoid overheating caused by long-term continuous operation of equipment
Rationally plan the operation path to reduce ineffective movement
Perform performance records of equipment use and assign tasks according to operation performance
Through reasonable selection, scientific operation, regular maintenance and experience accumulation, second-hand excavators can fully achieve or even exceed the efficiency performance of new machines. The key is to choose a reliable supplier and continuously optimize the use strategy.
