It costs about 1.1 million yuan to buy a 120 t · m tower crane, which is not a small amount for a construction contractor. In addition, in addition to the interest, the monthly salary and bonus of tower crane driver, maintenance mechanic and electrician, as well as the cost of power, oil and spare parts must be borne. After the completion of the project, the whole machine will be transported to the base for storage and maintenance, which will require another expenditure.
Advantages and disadvantages of renting tower crane
The advantages of renting 1 tower crane are:
(1) There is no need for a special person to take care of the tower crane. The leasing company is responsible for the driving, maintenance and repair of the tower crane;
(2) There is no need to ask about the entry and exit of tower cranes, storage and maintenance. That is to say, as long as the monthly rent is paid, the desired hoisting service can be obtained, and the rest can be ignored.
As for the calculation of the monthly rent of tower crane, there is no uniform regulation to follow so far. Here are two different calculation methods of the monthly rent of tower crane.
One is the interest on capital outlay.
120 t · m tower crane, the height of the hinge point of the boom root is 80 m, the length of the boom is 50 m, the price is 1.1 million yuan, the service life is 8 years, and the annual work is 10 months. (1) One time investment of tower crane is 1.1 million yuan; (2) annual interest rate is 12%, 8-year interest is 1056000 yuan in total; (3) annual depreciation rate is 10%, 8-year depreciation is 880000 yuan in total; (4) annual maintenance cost is 10%, 8-year expenditure is 880000 yuan in total; (5) annual rate of miscellaneous expenses of insurance, operation and management is 5%, 440000 yuan in total; (6) residual value is 200000 yuan after 8 years;
The second is baugerate method.

120 t · m tower crane, the height of the hinge point of the boom root is 80 m, the length of the boom is 50 m, the price is 1.1 million yuan, the service life is 10 years, and the annual work is 9 months. (1) One time investment of tower crane is 1.1 million yuan; (2) monthly interest and depreciation rate is 1.5%, with a total of 1.98 million yuan in 10 years; (3) monthly maintenance, operation and management miscellaneous expenses are 1.1%, with a total of 1.089 million yuan; (4) residual value is 150000 yuan after 10 years; The monthly rent of tower crane fluctuates greatly under the influence of market economy. In the first two years, it was over supply. The monthly rent was determined by the seller's market and remained high, reaching 70000 yuan / month at the peak. At present, the monthly rent of tower crane has dropped greatly, which is similar to the calculation result here. If the monthly rent is 55000 yuan, the total investment (purchase cost of tower crane) can be recovered after 2 years.
conclusion
Therefore, if there is a follow-up project waiting for tower crane construction, or if there are certain conditions in the base and logistics management, it seems more cost-effective to purchase one tower crane as a fixed asset. Through comparative analysis, if we decide to buy one tower crane, then we need to study what kind of tower crane is the most economical. The analysis of the cost of the tower crane shows that the cost of 50 m jib tower crane is about 10% higher than that of 40 m jib tower crane. However, the effective working range of 50 m jib crane is about 35% larger than that of 40 m jib crane. The use of longer jib can bring more convenience and flexibility to the construction and expand the service area of the tower crane. The cost analysis of tower crane also shows that under the same lifting capacity (or the same model of tower crane), the cost of rail tower crane is much higher than that of fixed tower crane. In order to save the cost of purchasing tower crane, fixed tower crane should be purchased. However, it must be noted that the fixed tower crane can be divided into two types: one is the fixed base frame type, and the other is the fixed base section of the tower body. It is the cheapest to choose the fixed tower crane with the foundation section of the tower body, which can be 10% - 12.5% cheaper than the rail tower crane.
