In the area of engineering, the leasing of engineering machinery is an important element in controlling costs and ensuring the smooth advancement of the project. However, in the face of a wide variety of engineering machinery and complex rental pricing systems, accurate knowledge and planning of budgets is not easy. Below is a presentation and analysis of some of the common engineering machine lease offers that help you plan the budget easily。
Rental of quotation excavators for earth-based engineering machinery
Excavators are the core equipment for the earthworks, the lease price of which varies according to the type and specifications. Small-scale excavators (6-10 tons) are usually used in small-scale landscaping and indoor excavations. The daily rent for such excavators is generally between $800 and $1,200. Small excavators are the choice of value for money for basic excavations of small construction or for some narrow site operations。
Medium-sized excavators (20 - 30 tons) are widely used in general construction earthworks at a daily rent of approximately $1,500 - 2,000. Medium-sized excavators have moderate excavation capacity and operational efficiency and are able to meet most of the conventional earth excavation requirements。
Large excavators (more than 30 tons) are powerful helpers in large-scale earth works such as mining, large-scale water works, etc. However, their rent is also high, usually at 2500-3500 yuan a day. The robust excavation and high yield of large-scale excavators can significantly reduce the duration of the work in large-scale operations, but at the same time there are certain requirements for the scope of the work, which may result in waste of costs。
Loader
Loaders are used for material handling and short-range transport in earthworks. The usual 3 - 5 cubic metre capacity loader is based on shifts at a price of about $1,000 - $1,500. If the material loads of the works are large, such as harbours, mines, etc., may require loaders with a larger capacity, the corresponding rent will increase, but will increase the efficiency of handling and reduce the duration of the work。
Lease of cranes for quoted vehicles
Car cranes are widely used in construction and equipment installation, with their highly mobile characteristics. 25 ton of car crane day rents are generally in the range of 2000 - 2,500 yuan to cover such tasks as the installation of small structures and the installation of street lights. This type of crane can also operate flexibly in complex construction environments such as narrow streets within the city。
For heavy lifting operations, such as the lifting of large bridge components and the installation of large industrial equipment, 50 tons or more of large vehicle cranes are required at a daily rent of up to $3,500 - $5,000. Large car cranes can ensure the safety and accuracy of suspensions, but require greater operating space and more specialized operations。
Tower crane
Tower cranes are indispensable equipment in the construction of high-rise buildings. The normal specification of the tower crane is rented at a monthly rate of $35,000, which is mainly priced on the basis of the gravity rectangular and altitude. The installation and dismantling of tower cranes is complex and requires professional team operations, and the general leasing company will include these services in the monthly rental cost. For super-high-rise buildings, a higher-specified tower crane is required, with a monthly lease likely to amount to $8120,000。
Concrete machinery lease offer concrete mixing stations
The lease price for concrete mixing stations depends on their production capacity. The monthly lease of a small mixer station (25 - 50 cubic metres per hour) is 22 - 30,000 yuan, suitable for small construction projects or the production of prefabricated units. Large mixing stations (more than 100 cubic metres per hour) can be rented for 5 - 8 million yuan per month for large infrastructure, such as large bridges, dams, etc., which can guarantee a large supply demand for concrete。
Concrete delivery pump
The rental price of the concrete delivery pump is based on the length of the arm shelf. 37 the pump bus fare of a rice arm rack is approximately $1,500-2000, which is suitable for concrete construction in general multi-storey buildings. For high-rise buildings, pumps with arms of 56 metres and above are more advantageous, and the cost of the shift is approximately 2500-3500 yuan。
Tenancy quotation for other ancillary engineering machinery
For example, for a roller, the light-wheeler (internal combustion) 6 - 8t costs approximately $800, for 8 - 10t about $1,000; for a double-rocker 12 - 15t about $1,400; for a 20 - 30t presser about 1800; for a vibration presser 18t - 22t about $1700; and for 25t about 1800。
After learning of the rental offers for these engineering machinery, the following points need to be taken into account in planning the budget:
Project size and duration
The rental cost is calculated on the basis of the size factors of the project, such as the size of the earth, the amount of the task to be carried out for the suspension, the quantity of concrete used and the duration of the work, the selection of the appropriate type and quantity of mechanical equipment. For longer-term projects, long-term leases could be considered for more favourable prices。
Co-use of equipment
Different engineering machines, such as cranes and loaders, often need to be accompanied in engineering. Coordination and sequencing of use of equipment should be taken into account in budget planning to avoid idle or excessive lease of equipment。
Contingency budget
Taking into account the possibility of mechanical equipment malfunctioning, repairing or requiring temporary additional equipment, a certain percentage of the contingency budget is generally set aside at around 10-20 per cent of the total lease budget。
A detailed understanding of the lease price of the engineering machinery and a rational planning budget will allow better control of the cost of the work, ensure that the construction is carried out as planned and avoid delays and cost overruns due to inadequate budgets or unreasonable rental of equipment。
