As a vertical vehicle, home elevators are inseparable from people's daily life. How to buy an elevator can save time and energy, value for money, and avoid disputes. Buyers and agents need to pay attention to the following ten details.
Determine the type of elevator as early as possible
During the construction planning period, the purpose of the building should be clarified, because the types of elevators used for different purposes are very different, and subsequent changes are very troublesome. After determining the use of the building, passenger flow analysis should be based on factors such as floor area, floor, traffic and elevator location to determine speed, load capacity, number of units required, machine room type and type of tractor.
Start planning after approval
After determining the type, speed, load capacity, number of units, etc., the blueprint can be designed. For the civil engineering part of elevators, the design department usually draws the same type of standard civil engineering drawings together with professional elevator manufacturers to draw different structures of building elevators. The size is more versatile 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 the waste of space, but also reduces the trouble of future construction.
Reasonable selection of manufacturers and brands
According to your own budget and project positioning, it is relatively scientific to choose the bid of the same level unit. Of course, you can also choose a large area, and finally determine the level according to the degree of difference. Elevator dealers and agents may also bid, their prices will be high, but the strength can be invested. Choose the manufacturer directly, the quality is relatively safe, after-sales service will be more in place, but the payment terms are more demanding. Industry practice requires full or basic payment before shipment.
Because of the need to select elevator functions
Each elevator factory has an elevator function table, and buyers need to understand these functions. The required function cannot be deleted, the necessary function is not selected, and the auxiliary function is selected. For example, there is no mandatory requirement for the barrier-free elevator function for residential projects when the acceptance is completed. The usual practice is not to consider it. For public building projects, accessibility features should be considered.
Clearly avoid price disputes
The full price of the elevator project should include all equipment prices, transportation costs, customs duties, insurance fees, installation fees, commissioning fees and the manufacturer’s commitment to the owner’s pre- and after-sales warranty, but the factory construction department will deliver the installed owner to accept. When the qualified elevator is completed, some subsequent costs are borne by the owner, such as elevator registration fee, installation inspection fee, fire protection (equipment) inspection fee and elevator annual inspection fee. The above-mentioned related costs of the supply and demand parties should be implemented in the contract as much as possible. Clearing the responsibilities of both parties in writing is the best way to avoid disputes. When bidding, elevator manufacturers need to report the price of wearing parts and maintenance and repair costs. This part of the cost relates to the cost of using the operation in the future. Property companies pay more attention. Overall planning lead time
In view of the progress of the civil construction of the building, the purchaser can request the manufacturer of the elevator to specify a delivery date. The delivery period of general manufacturers is 2 and a half months to 4 months. The elevator equipment of general buildings is best to enter the site before the ceiling of the building and the outdoor tower crane is about to be demolished. If it arrives before then, the warehouse will inevitably happen. Regulatory issues, after this, there will be two upgrades, processing and other costs. Generally, the elevator factory will have a free storage period for a period of time. If it is not delivered at this time, the manufacturer will charge a certain fee.
Separate interface for easy switching
Elevator installation is closely related to the general contractor's construction unit (civil construction and installation), fire protection unit and weak current unit. The interface between the two should be clearly defined in order to complete the handover during the construction process to prevent disputes.
The elevator is divided into three main links
First of all, elevator manufacturers must guarantee the quality of their products. The production quality of companies with production certificates usually has no major problems, but durability and stability are different. Second, pay attention to the level of installation and debugging. Installation quality is very important. The installation team is basically a factory or long-term cooperation. Commissioning is usually carried out by the elevator factory. Finally, after-sales service was clarified. The elevator repair team must be responsible for after-sales service.
Elevator acceptance is not sloppy
The National Bureau of Technical Supervision has an acceptance procedure for elevators, but it is usually only responsible for safety and not comprehensive enough. The owner and the supervision unit must carry out inspection and acceptance according to the elevator acceptance standards and the functions determined in the contract, such as strict unpacking acceptance, process monitoring, concealed acceptance and functional acceptance.
Special personnel control the elevator to ensure safety
After the installation and commissioning are completed and the internal acceptance is completed, the elevator has conditions of use. According to regulations, elevators are not allowed to be used without inspection and acceptance by the Technical Supervision Bureau, but there is usually a period of time before the installation of the elevator, the external elevator has been dismantled, and other work is generally not completed, and indoor elevators are required. At this time, the elevator unit and the general packaging unit should sign an agreement. The elevator unit arranges a special person to open the elevator, and the general packaging unit uses the elevator according to the requirements of the elevator unit and bears the cost.
