Elevator procurement needs to pay attention to several detai
1. Determine the type of elevator early
During the planning period of the building, the purpose of the building should be clarified, because the types of elevators used for different purposes vary widely, and late changes are very troublesome. After determining the use of the building, passenger flow analysis should be based on factors such as the floor area, floor, flow of people, and location of the elevator to determine speed, load capacity, number of units required, type of machine room, and type of traction machine.

Start planning after planning approval
After the type, speed, load capacity, number of units, etc. are determined, the blueprint can be designed. Regarding the civil engineering part of the elevator, the design department usually draws the same type of standard civil engineering drawings with the different types of structures of the elevator shafts of the building. The size is more versatile in order to meet the needs of general manufacturers. However, the requirements of different manufacturers are still different. If the manufacturer is determined in advance, the design can be designed according to the corresponding size, which not only reduces space waste, but also reduces the trouble of construction in the future.

Choose manufacturers and brands
According to your own budget and project positioning, it is relatively scientific to select bids for units of the same level. Of course, it is also possible to choose a large area, and finally determine the grade according to the degree of difference. Elevator dealers and agents may also bid, their prices will be high, but the strength can be invested. Direct selection of manufacturers, the quality is relatively secure, after-sales service will be more in place, but the payment terms are more demanding. Industry practice requires full payment or full payment before shipment.
4,
Factor selection elevator function
Every elevator manufacturer has an elevator function table, and the purchaser needs to understand these functions. The function must not be dropped, the necessary function is not selected, and the auxiliary function is selected. For example, the barrier-free elevator function, residential projects have no mandatory requirements at the completion of the acceptance, the usual practice is not to consider. For public construction projects, accessibility features should be considered.
5,
Clear price avoidance dispute
The entire price of the elevator project shall include all equipment prices, transportation costs, customs duties, insurance fees, installation fees, commissioning fees and the manufacturer's commitment to the owner's pre-sales and after-sales warranty, but the factory construction department will deliver the installed acceptance to the property owner. When the completed and qualified elevator, some post-costs are borne by the owner, such as elevator registration fee, installation acceptance inspection fee, fire (equipment) inspection fee and annual annual inspection fee of the elevator. The above-mentioned related fees, both supply and demand should be implemented as much as possible in the contract costs. This part of the cost involves the cost of future operation, and the property company is more concerned.
6,
Overall planning of delivery time
In view of the progress of civil construction of buildings, the purchaser may request the manufacturer of the elevator to specify the date of delivery. The general manufacturer's delivery period takes 2 and a half months to 4 months, and the general building's elevator equipment is best to enter the site before the building has been capped and the outdoor tower crane will be demolished. If it arrives before this, warehouses will inevitably occur. The problem of custody, and after that, there will be secondary lifting, handling and other expenses. Usually, the elevator factory will have a free period of storage for a certain period of time. If it is not delivered at this time, the manufacturer will charge a certain fee.
7,
Divided interface for easy exchange
Elevator installation is closely related to the general contractor construction unit (civil construction and installation), fire protection unit, and weak electricity unit. The interface between the two should be clearly defined so that the handover can be done during the construction process to prevent disputes.
8,
Put the elevator into three major links
First of all, elevator manufacturers must guarantee the quality of their products. The production quality of a company with a production certificate usually does not have a big problem, but the durability and stability are different. Secondly, it is necessary to pay attention to the level of installation and commissioning. The quality of the installation is very important. The installation team is basically the factory or long-term cooperation. The commissioning is usually carried out by the elevator factory. In the end, the after-sales service is clearly defined. The elevator maintenance team must be responsible for the after-sales service.
9,
Elevator acceptance is not sloppy
The State Bureau of Technical Supervision has an acceptance procedure for elevators, but they are usually only responsible for safety and are not comprehensive enough. The owner and the supervising unit must check and accept the items according to the elevator acceptance criteria and the functions determined in the contract, such as strict unpacking acceptance, process monitoring, concealed acceptance and functional acceptance.
10.
Special person controls the elevator to ensure safety
After the installation and commissioning is completed and the internal acceptance is completed, the elevator has the conditions for use. According to the regulations, the elevator is not allowed to be used without technical supervision and acceptance, but usually there is a period of time before the elevator is installed, the outer elevator has been dismantled, the other work of the general package unit is not completed, and the indoor elevator is needed. At this point, the elevator unit and the general package unit should sign an agreement, the elevator unit arranges a special person to open the elevator, and the general package unit uses the elevator according to the demand of the elevator unit and bears the expenses.
