出租模式

Rental mode

按时间出租

Rent by time

按天出租：以天为单位计算租金，适用于短期、临时性的小工程，如小区内局部道路维修、小型停车场改造等，冷再生机一般使用 1-3 天。

Rental by Day: Rent is calculated on a daily basis and is suitable for short-term, temporary small projects such as local road maintenance and small parking lot renovation in residential areas. Cold recycling machines are generally used for 1-3 days.

按月出租：对于工期相对较长，如持续 1-3 个月的城市支路改造、乡村道路建设等工程，常采用按月租赁的方式，便于承租方进行成本核算和施工安排。

Monthly rental: For projects with relatively long construction periods, such as urban branch road renovation or rural road construction lasting 1-3 months, monthly leasing is often used to facilitate cost accounting and construction arrangements for the lessee.

按工程量出租：根据冷再生机完成的具体工程量来计算租金，比如每平方米或每立方米的再生工程量定价。这种方式适用于工程量明确，但施工时间不确定的项目，如大型高速公路的分段维修工程，出租方可以根据实际完成的工程数量来收取租金，承租方也可根据实际工程量控制成本。

Rental by Quantity: Rent is calculated based on the specific amount of work completed by the cold regeneration machine, such as pricing per square meter or cubic meter of regeneration work. This method is suitable for projects with clear engineering quantities but uncertain construction time, such as segmented maintenance projects on large highways. The lessor can charge rent based on the actual completed engineering quantity, and the lessee can also control costs based on the actual engineering quantity.

租金影响因素

Factors affecting rent

设备型号与规格：大型、高性能的冷再生机，如铣拌宽度大、功率高的设备，租金相对较高。像维特根 W2000 型等进口高端设备，日租金可能在 5000-10000 元左右；而国产的一些小型冷再生机，日租金可能在 2000-5000 元。

Equipment model and specifications: Large, high-performance cold recycling machines, such as those with large milling and mixing widths and high power, have relatively high rental costs. Imported high-end equipment such as the Wirtgen W2000 model may have a daily rent of around 5000-10000 yuan; Some small domestic cold recycling machines may have a daily rent of 2000-5000 yuan.

设备新旧程度：新设备由于性能更好、故障概率低，租金通常比旧设备高。一般来说，使用年限在 1-2 年的新设备，租金可能比使用 3-5 年的设备高出 20%-50%。

Equipment age: Due to better performance and lower probability of failure, new equipment usually incurs higher rent compared to old equipment. Generally speaking, the rent for new equipment with a lifespan of 1-2 years may be 20% -50% higher than that for equipment with a lifespan of 3-5 years.

租赁期限：租赁时间越长，平均每天的租金往往越低。以月为单位租赁时，月租金可能是按天租赁日租金的 20-25 倍左右，相比按天租能有一定的优惠。

Lease term: The longer the lease term, the lower the average daily rent tends to be. When renting on a monthly basis, the monthly rent may be around 20-25 times the daily rent, which can offer some discounts compared to renting on a daily basis.

市场供需关系：在道路建设旺季，冷再生机需求大，租金会上涨；淡季时，租金可能会有所下降，波动范围在 20%-50% 左右。

Market supply and demand relationship: During the peak season of road construction, there is a high demand for cold recycling machines, and rent will increase; During the off-season, rent may decrease slightly, with a fluctuation range of around 20% -50%.

地理位置：经济发达地区、施工项目多的地区，冷再生机租金相对较高。如在一线城市，租金可能比二三线城市高出 30...

Geographical location: In economically developed areas with many construction projects, the rent for cold recycling machines is relatively high. In first tier cities, rent may be 30% higher than in second - and third tier cities
