【 Weak current College 】 developer lift options and comprehensive cost considerations

National Elevator procurement volume in 2003 for the first time exceeded 7 million units, while the residential lift more than 50%. In the past, design institutes and developers choose elevator has a serious misunderstanding is that they have failed to consider the cost of comprehensive cost and use. The so-called comprehensive cost refers to: lift design, construction, Elevator equipment, lift installation, maintenance and service costs. Use the cost refers to the maintenance costs, Elevator elevator and royalty (including electricity), lift the annual examination fees.

Currently, many elevator choice when construction costs are high, Elevator equipment high costs, maintenance costs, high lift tariff large became the country with the largest residential elevator. The current use of VVVF lift even in comprehensive cost a lot, and royalties. We press the 9-storey residential choice brand VVVF lift calculations: civil engineering needs concrete wells road, and the engine room, the civil costs should be 8-10 million, and thanks to declare construction height, can not be very high, so also built a little. Elevator equipment price 18-22 million, the installation fee 2.5-3 million, plus transportation costs and other price should be around $ 24-26. Two comprehensive cost reach 35 million. Elevator use cost: a motor power 15KW, namely hourly use need 15 units of electricity, lighting and other, using the one-hour power consumption of about 20 degrees. And residential elevator calculation of electricity tariff charges by industry in General, prices from 0.8-1.2 Yuan/degree. Elevator maintenance: brand lift requires 500 Yuan/Taiwan maintenance costs, maintenance costs 6000-10000 Yuan/year, and such royalties are amazing. General Developer never carefully these accounts in the sales brochure on royalties from no elevator, the number of households in the payment management fee every time you feel that the elevator costs are too high, and there is no property management company. If the same 9-story residential we select machine-roomless elevator and then calculate a tent: a comprehensive cost: construction does not require a concrete wells road, only need a frame structure with brick walls, construction costs can be reduced by 5 million; if using permanent magnet synchronous gearless price is only 20-30 million. This comprehensive cost only about 28-30 million. More important is the toll is much lower, generally resembling the host power only 50% of the ordinary VVVF-65%, if you press 9-1000KG. 1.0M/S elevator, motor power only need 6.7KW, tariff only famous VVVF lift 40%, the royalty is greatly reduced; and gearless machine dimensional premiums can also be more economical. Especially in the current Chinese energy constraints, choose better elevator, to conserve energy, reduce development costs, royalties, and why developers at four more things not to do?
