冷再生機能在現場對舊路面材料進行破碎、拌和并重新利用，減少材料運輸與廢棄物排放，在公路大修、市政道路翻新等工程中應用廣泛。因設備購置成本較高，租賃成為多數施工單位的優選方式。了解冷再生機租賃的核心要點，能幫助施工方選對設備、控制成本，確保工程順利推進。

　　The cold recycling machine can crush, mix and reuse old pavement materials on site, reducing material transportation and waste emissions. It is widely used in highway maintenance, municipal road renovation and other projects. Due to the high cost of equipment procurement, leasing has become the preferred method for most construction units. Understanding the core points of leasing cold recycling machines can help construction parties select the right equipment, control costs, and ensure the smooth progress of the project. 

　　冷再生機租賃需先明確設備類型與技術參數，匹配工程實際需求。按作業寬度劃分，常見的有多種型號，作業寬度需與施工路段寬度適配 —— 鄉村道路可選擇相應寬度設備，能單次完成半幅路面施工；國道、省道則需更寬設備，提高作業效率。設備功率是關鍵參數，功率越大，破碎硬度較高的路面時更有力，不易出現卡滯，適合基層強度高的工程；中小功率設備則適用于瀝青表層再生或砂石路面處理。此外，需關注設備的拌和深度，根據道路設計厚度選擇，租賃時需確認設備是否能滿足工程所需的深度調節范圍。

　　The leasing of cold recycling machines requires a clear understanding of the equipment type and technical parameters to match the actual needs of the project. Divided by the width of the homework, there are many common models, and the homework width needs to be adapted to the width of the construction section - for rural roads, corresponding width equipment can be selected to complete half of the road surface construction in one go; National and provincial roads require wider equipment to improve operational efficiency. Equipment power is a key parameter. The higher the power, the more powerful it is when breaking hard road surfaces, making it less prone to jamming and suitable for projects with high base strength; Small and medium power equipment is suitable for asphalt surface regeneration or sand and gravel pavement treatment. In addition, attention should be paid to the mixing depth of the equipment, and the selection should be based on the thickness of the road design. When renting, it is necessary to confirm whether the equipment can meet the depth adjustment range required for the project. 

　　租賃流程的規范性直接影響合作效率，需提前做好溝通與約定。需提供工程基本信息，包括施工地點、工期、每日作業量，便于租賃方調配設備與安排操作人員。設備交付前需明確驗收標準，檢查設備外觀是否完好、關鍵部件是否正常運行，試駕時觀察設備運行是否平穩、儀表顯示是否正常，避免接收存在故障的設備影響施工。租賃協議需詳細注明權責，包括設備維修責任、燃油供應方式、逾期租賃的計費標準等，尤其要明確設備故障的維修響應時間，減少因設備停機造成的工期延誤。

　　The standardization of the leasing process directly affects the efficiency of cooperation, and communication and agreements need to be made in advance. Firstly, it is necessary to provide basic information about the project, including the construction site, schedule, and daily workload, in order to facilitate the lessee's allocation of equipment and arrangement of operators. Before delivering the equipment, it is necessary to clarify the acceptance criteria, check whether the appearance of the equipment is intact and whether the key components are operating normally. During the test drive, observe whether the equipment runs smoothly and whether the instrument display is normal, in order to avoid receiving equipment with faults that may affect construction. The lease agreement should specify the rights and responsibilities in detail, including equipment maintenance responsibilities, fuel supply methods, and billing standards for overdue leases. In particular, it should clarify the maintenance response time for equipment failures to reduce project delays caused by equipment downtime. 

　　租賃期間的設備使用與維護需遵循規范，確保施工質量與設備。操作人員需熟悉設備性能，嚴格按照操作規程作業，啟動前檢查冷卻液、液壓油液位，作業中關注發動機溫度與液壓系統壓力，避免超負荷運行。每日作業結束后，需對設備進行基本保養：清理破碎刀具上的纏繞物，檢查刀具磨損情況，對關鍵部位加注潤滑油，確保次日正常啟動。施工場地需做好防護，設置警示標志，避免無關人員靠近作業區域，夜間停放設備時需停放在封閉場地并鎖好，防止部件被盜。

　　The use and maintenance of equipment during the lease period must comply with regulations to ensure construction quality and equipment safety. Operators need to be familiar with the equipment performance, strictly follow the operating procedures, check the coolant and hydraulic oil levels before starting, pay attention to the engine temperature and hydraulic system pressure during operation, and avoid overloading operation. After daily homework, basic maintenance of the equipment is required: clean the entanglement on the broken cutting tools, check the wear of the tools, add lubricating oil to key parts, and ensure normal start-up the next day. The construction site should be well protected with safety measures, warning signs should be set up to prevent unrelated personnel from approaching the work area. When parking equipment at night, it should be parked in a closed area and locked to prevent parts from being stolen. 

　　租賃成本的核算需綜合考慮多方面因素，避免隱性支出。基礎租金通常按天或按月計算，不同型號設備租金差異較大，長期租賃可與出租方協商優惠，降低日均成本。附加費用需提前確認，如設備運輸費、操作人員工資、超出約定作業時間的加班費等，這些費用若未提前約定，可能導致終成本超出預算。成本控制可從合理規劃工期入手，根據工程進度精準安排租賃時長，避免設備閑置；同時提高設備利用率，攤薄單位作業成本。

　　The accounting of leasing costs requires comprehensive consideration of multiple factors to avoid implicit expenses. Basic rent is usually calculated on a daily or monthly basis, with significant differences in rent for different types of equipment. Long term leasing can negotiate discounts with the lessor to reduce daily costs. Additional costs need to be confirmed in advance, such as equipment transportation fees, operator salaries, overtime pay beyond agreed working hours, etc. If these costs are not agreed upon in advance, they may result in final costs exceeding the budget. Cost control can start with reasonable planning of the construction period, accurately arranging the leasing duration according to the project progress, and avoiding equipment idle; Simultaneously improve equipment utilization and dilute unit operating costs. 

　　冷再生機租賃的優勢在于靈活性與經濟性，尤其適合短期工程或初次嘗試再生工藝的施工單位。無需承擔設備購置的大額資金投入，可根據不同工程需求更換設備型號，降低投資風險。租賃方通常會提供技術支持，幫助施工方掌握冷再生工藝要點，提升施工質量。對于工期緊張的工程，租賃設備能快速進場施工，比購置設備節省時間成本，加快工程進度。

　　The advantage of leasing a cold recycling machine lies in its flexibility and economy, especially suitable for short-term projects or construction units that are trying recycling technology for the first time. No need to bear the large capital investment for equipment procurement, equipment models can be replaced according to different engineering needs to reduce investment risks. The lessee usually provides technical support to help the construction party master the key points of cold recycling technology and improve construction quality. For projects with tight schedules, renting equipment can quickly enter the construction site, saving time and cost compared to purchasing equipment, and accelerating project progress.
