冷再生机能在现场对旧路面材料进行破碎、拌和并重新利用，减少材料运输与废弃物排放，在公路大修、市政道路翻新等工程中应用广泛。因设备购置成本较高，租赁成为多数施工单位的优选方式。了解冷再生机租赁的核心要点，能帮助施工方选对设备、控制成本，确保工程顺利推进。

　　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. 

　　冷再生机租赁需先明确设备类型与技术参数，匹配工程实际需求。按作业宽度划分，常见的有多种型号，作业宽度需与施工路段宽度适配 —— 乡村道路可选择相应宽度设备，能单次完成半幅路面施工；国道、省道则需更宽设备，提高作业效率。设备功率是关键参数，功率越大，破碎硬度较高的路面时更有力，不易出现卡滞，适合基层强度高的工程；中小功率设备则适用于沥青表层再生或砂石路面处理。此外，需关注设备的拌和深度，根据道路设计厚度选择，租赁时需确认设备是否能满足工程所需的深度调节范围。

　　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. 

　　租赁流程的规范性直接影响合作效率，需提前做好沟通与约定。需提供工程基本信息，包括施工地点、工期、每日作业量，便于租赁方调配设备与安排操作人员。设备交付前需明确验收标准，检查设备外观是否完好、关键部件是否正常运行，试驾时观察设备运行是否平稳、仪表显示是否正常，避免接收存在故障的设备影响施工。租赁协议需详细注明权责，包括设备维修责任、燃油供应方式、逾期租赁的计费标准等，尤其要明确设备故障的维修响应时间，减少因设备停机造成的工期延误。

　　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. 

　　租赁期间的设备使用与维护需遵循规范，确保施工质量与设备。操作人员需熟悉设备性能，严格按照操作规程作业，启动前检查冷却液、液压油液位，作业中关注发动机温度与液压系统压力，避免超负荷运行。每日作业结束后，需对设备进行基本保养：清理破碎刀具上的缠绕物，检查刀具磨损情况，对关键部位加注润滑油，确保次日正常启动。施工场地需做好防护，设置警示标志，避免无关人员靠近作业区域，夜间停放设备时需停放在封闭场地并锁好，防止部件被盗。

　　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. 

　　租赁成本的核算需综合考虑多方面因素，避免隐性支出。基础租金通常按天或按月计算，不同型号设备租金差异较大，长期租赁可与出租方协商优惠，降低日均成本。附加费用需提前确认，如设备运输费、操作人员工资、超出约定作业时间的加班费等，这些费用若未提前约定，可能导致终成本超出预算。成本控制可从合理规划工期入手，根据工程进度精准安排租赁时长，避免设备闲置；同时提高设备利用率，摊薄单位作业成本。

　　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. 

　　冷再生机租赁的优势在于灵活性与经济性，尤其适合短期工程或初次尝试再生工艺的施工单位。无需承担设备购置的大额资金投入，可根据不同工程需求更换设备型号，降低投资风险。租赁方通常会提供技术支持，帮助施工方掌握冷再生工艺要点，提升施工质量。对于工期紧张的工程，租赁设备能快速进场施工，比购置设备节省时间成本，加快工程进度。

　　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.
