When purchasing a used excavator, testing the machine is a crucial step in assessing its condition. By conducting a thorough test, you can understand the excavator’s performance, functionality, and potential issues, leading to a more informed purchasing decision. Shanghai Wabaiwan Used Excavator Export (wabaiwan) offers comprehensive testing support to ensure that the equipment you purchase meets project requirements and delivers good value for money. This article will detail the steps and key considerations for testing a used excavator, helping you make an informed decision.

1. 外觀檢查與基本信息確認

Visual Inspection and Basic Information Verification

在啟動挖掘機之前，首先需要進行外觀檢查，并確認設備的基本信息。外觀檢查可以幫助您識別任何明顯的損壞、磨損或維修跡象，而確認基本信息則有助于確保設備的型號、年限和工作小時數符合您的需求。

Before starting the excavator, begin with a visual inspection and verification of the basic information. A visual inspection can help you identify any visible damage, wear, or signs of repairs, while verifying basic information ensures that the machine’s model, age, and operating hours match your requirements.

• 外觀檢查：仔細檢查挖掘機的車身、底盤、鏟斗和履帶，尋找任何裂縫、變形或異常磨損的跡象。

• 銘牌和序列號：確認設備的銘牌和序列號，確保其與文件記錄一致。

• 工作小時數：檢查儀表盤上的工作小時數，并與賣方提供的信息進行核對。

• 液壓系統：檢查液壓系統是否有泄漏或損壞的跡象，尤其是油缸和管道連接處。

• Visual Inspection: Carefully examine the excavator’s body, undercarriage, bucket, and tracks for any signs of cracks, deformation, or abnormal wear.

• Nameplate and Serial Number: Verify the machine’s nameplate and serial number to ensure they match the documentation.

• Operating Hours: Check the operating hours on the dashboard and cross-check with the seller’s information.

• Hydraulic System: Inspect the hydraulic system for signs of leaks or damage, particularly at the cylinder and hose connections.

2. 啟動與怠速測試

Startup and Idle Testing

在完成外觀檢查后，您可以啟動挖掘機并進行怠速測試。啟動和怠速測試可以幫助您了解發動機的啟動性能、怠速穩定性以及是否存在異常聲音或振動。

After completing the visual inspection, you can start the excavator and conduct an idle test. The startup and idle test will help you assess the engine’s startup performance, idle stability, and check for any unusual noises or vibrations.

• 啟動性能：觀察發動機的啟動是否順暢，檢查是否需要多次嘗試或長時間預熱。

• 怠速穩定性：在怠速狀態下觀察發動機的運轉是否平穩，是否有異常的震動或噪音。

• 排煙情況：檢查排氣管是否有異常的排煙現象，如黑煙、白煙或藍煙，這可能表明發動機存在問題。

• 液壓油溫：在怠速時檢查液壓油溫，確保其在正常范圍內，避免過熱。

• Startup Performance: Observe if the engine starts smoothly and check if it requires multiple attempts or prolonged warming up.

• Idle Stability: Monitor the engine’s operation at idle, looking for any unusual vibrations or noises.

• Exhaust Smoke: Check the exhaust for abnormal smoke, such as black, white, or blue smoke, which may indicate engine issues.

• Hydraulic Oil Temperature: Check the hydraulic oil temperature at idle to ensure it is within the normal range, avoiding overheating.

3. 操作測試與功能檢查

Operational Testing and Function Check

啟動并進行怠速測試后，接下來是對挖掘機的各項操作功能進行測試。這一步可以幫助您評估設備的操作靈敏度、液壓系統的響應速度以及各個部件的正常運作情況。

After the startup and idle test, the next step is to test the operational functions of the excavator. This step helps you assess the machine’s operational responsiveness, the hydraulic system’s reaction speed, and the proper functioning of various components.

• 動臂與鏟斗操作：測試動臂、斗桿和鏟斗的升降、伸縮和旋轉，確保操作平穩，無卡頓或延遲。

• 履帶行走：前后行駛和原地轉向，檢查履帶的反應速度和穩定性，注意是否有異響或異常振動。

• 液壓系統：在不同的負載下操作挖掘機，檢查液壓系統是否能夠保持穩定的壓力和流量。

• 回轉功能：測試挖掘機的回轉平臺，確保其能夠平穩地旋轉，無異常噪音或卡頓。

• Boom and Bucket Operation: Test the boom, arm, and bucket’s lifting, extending, and rotating movements, ensuring smooth operation without stuttering or delays.

• Track Walking: Move forward, backward, and pivot on the spot to check the track’s responsiveness and stability, noting any unusual noises or vibrations.

• Hydraulic System: Operate the excavator under different loads to check if the hydraulic system maintains stable pressure and flow.

• Swing Function: Test the excavator’s swing platform to ensure it rotates smoothly without abnormal noises or stuttering.

4. 負載測試與耐久性評估

Load Testing and Durability Assessment

為了更深入地了解二手挖掘機的性能和耐久性，負載測試是必不可少的。通過施加不同的負載，您可以評估設備在高強度工作條件下的表現，從而判斷其是否適合長時間的施工任務。

For a deeper understanding of the used excavator’s performance and durability, load testing is essential. By applying different loads, you can assess how the machine performs under high-stress conditions, determining its suitability for long-term construction tasks.

• 滿載測試：將挖掘機的鏟斗裝滿負載，檢查設備在重負荷下的操作穩定性和液壓系統的響應。

• 連續操作：進行一段時間的連續操作，觀察設備的穩定性、溫度變化以及液壓系統是否出現疲勞現象。

• 發動機表現：在高負載下監測發動機的表現，確保其能夠持續提供足夠的動力，無過熱或功率下降現象。

• 設備耐久性：通過長時間、高強度的測試，評估設備的整體耐久性和可靠性，確保其能夠勝任未來的施工任務。

• Full Load Test: Load the excavator’s bucket to capacity and check the machine’s operational stability and hydraulic system response under heavy loads.

• Continuous Operation: Conduct continuous operation for an extended period, observing the machine’s stability, temperature changes, and any signs of hydraulic fatigue.

• Engine Performance: Monitor the engine’s performance under high loads to ensure it consistently provides sufficient power without overheating or power loss.

• Equipment Durability: Assess the overall durability and reliability of the machine through prolonged, high-intensity testing, ensuring it can handle future construction tasks.
