水泥撒布車作為道路基層施工的關(guān)鍵設(shè)備，其出租時(shí)的工作時(shí)長受設(shè)備性能、作業(yè)環(huán)境、任務(wù)量等多重因素影響。合理規(guī)劃工作時(shí)長，是出租方與承租方都需關(guān)注的核心問題。

　　As a key equipment for road base construction, the working hours of cement spreading vehicles during rental are affected by multiple factors such as equipment performance, operating environment, and workload. Reasonable planning of work hours is a core issue that both landlords and tenants need to pay attention to.

　　設(shè)備自身性能是決定工作時(shí)長的基礎(chǔ)。功率較大的車型散熱性能更強(qiáng)，滿負(fù)荷運(yùn)轉(zhuǎn)時(shí)可連續(xù)工作 6-8 小時(shí)；功率較小的車型連續(xù)工作 4-5 小時(shí)后，需停機(jī) 30 分鐘冷卻。撒布系統(tǒng)自動(dòng)化程度高的設(shè)備，可減少操作失誤，間接延長有效工作時(shí)間；手動(dòng)調(diào)節(jié)的老式設(shè)備，因需頻繁停車調(diào)整，實(shí)際有效時(shí)長會(huì)縮短。設(shè)備保養(yǎng)狀況影響出勤率，定期保養(yǎng)的水泥撒布車，每月可正常作業(yè) 25 天以上，保養(yǎng)缺失的設(shè)備可能因故障每周停機(jī) 1-2 天。

　　The performance of the device itself is the basis for determining the working hours. Models with higher power have stronger heat dissipation performance and can work continuously for 6-8 hours at full load; After continuous operation for 4-5 hours, models with lower power need to be stopped for 30 minutes for cooling. Equipment with high automation level in the spreading system can reduce operational errors and indirectly extend effective working time; Old style equipment with manual adjustment may have a shorter actual effective duration due to frequent parking adjustments. The maintenance status of equipment affects the attendance rate. Cement spreading trucks that undergo regular maintenance can operate normally for more than 25 days per month, while equipment that is missing maintenance may be shut down for 1-2 days per week due to malfunctions.

　　作業(yè)環(huán)境對工作時(shí)長限制明顯。春秋季氣溫適宜時(shí)，水泥撒布車可保持每天 8-10 小時(shí)作業(yè)強(qiáng)度。夏季高溫時(shí)，需避開正午時(shí)段，每天有效時(shí)長縮短至 6-7 小時(shí)，還需增加水箱補(bǔ)水。冬季低溫時(shí)，需預(yù)熱料倉，每天實(shí)際作業(yè)時(shí)間降至 5-6 小時(shí)，且每 2 小時(shí)需停機(jī)清理管道。雨天或大風(fēng)天氣則需完全停工。

　　The homework environment has significant limitations on working hours. When the temperature is suitable in spring and autumn, the cement spreading truck can maintain a working intensity of 8-10 hours per day. During high temperatures in summer, it is necessary to avoid the noon period and shorten the effective duration to 6-7 hours per day. Additionally, it is necessary to increase water tank replenishment. During low temperatures in winter, it is necessary to preheat the silo, reducing the actual working time to 5-6 hours per day, and stopping the machine every 2 hours to clean the pipelines. Complete shutdown is required in rainy or windy weather.

　　施工任務(wù)量與強(qiáng)度決定工作時(shí)長彈性。路基處理初期，鋪設(shè)厚度較薄時(shí)，撒布車行進(jìn)速度快，單日作業(yè)面積大，工作時(shí)長控制在 8 小時(shí)內(nèi)即可。鋪設(shè)厚度增加時(shí)，設(shè)備需降低速度，單日作業(yè)面積縮減，需延長工作時(shí)長至 10 小時(shí)，或增加設(shè)備數(shù)量。施工路段含復(fù)雜地形時(shí)，每小時(shí)有效作業(yè)里程減少，可能需要每天多工作 1-2 小時(shí)，但需避免連續(xù)超時(shí)長作業(yè)。

　　The amount and intensity of construction tasks determine the flexibility of working hours. In the early stage of roadbed treatment, when the laying thickness is relatively thin, the spreading vehicle travels fast, the daily operating area is large, and the working time can be controlled within 8 hours. When the laying thickness increases, the equipment needs to slow down, reduce the daily operating area, extend the working hours to 10 hours, or increase the number of equipment. When the construction section contains complex terrain, the effective operating mileage per hour is reduced, and it may require an additional 1-2 hours of work per day, but continuous overtime work should be avoided.

　　承租方施工組織能力影響工作時(shí)長利用。合理工序銜接可減少設(shè)備閑置，料倉補(bǔ)給效率高，每次補(bǔ)料時(shí)間短，不影響連續(xù)作業(yè)；補(bǔ)料延遲則會(huì)減少全天工作時(shí)長。操作人員熟練度關(guān)鍵，經(jīng)驗(yàn)豐富的司機(jī)能減少返工，間接縮短必要工作時(shí)長。

　　The lessee's construction organization ability affects the utilization of working hours. Reasonable process connection can reduce equipment idle, improve the efficiency of silo replenishment, shorten the replenishment time each time, and not affect continuous operation; Delay in material replenishment will reduce the working hours of the entire day. The proficiency of operators is crucial, and experienced drivers can reduce rework and indirectly shorten necessary working hours.

　　設(shè)備維護(hù)與保養(yǎng)對工作時(shí)長有剛性約束。水泥撒布車每周需安排半天例行保養(yǎng)，合同期較長時(shí)，每月需 1 天深度保養(yǎng)。每次作業(yè)結(jié)束后，需清洗撒布系統(tǒng)，雖不納入有效時(shí)長，但影響次日開工。

　　Equipment maintenance and upkeep have rigid constraints on working hours. The cement spreading truck needs to be scheduled for half a day of routine maintenance every week, and for longer contract periods, it needs to undergo one day of deep maintenance per month. After each assignment, the spreading system needs to be cleaned. Although it is not included in the effective duration, it affects the start of the next day's work.

　　水泥撒布車出租的工作時(shí)長是動(dòng)態(tài)平衡的結(jié)果，需在設(shè)備承受能力、環(huán)境限制與施工需求間找最優(yōu)解。雙方協(xié)同配合才能實(shí)現(xiàn)效率與成本的平衡，確保道路施工順利推進(jìn)。

　　The working hours of cement spreader rental are the result of dynamic balance, and the optimal solution needs to be found between equipment capacity, environmental constraints, and construction requirements. Collaboration and cooperation between both parties are necessary to achieve a balance between efficiency and cost, ensuring the smooth progress of road construction.
