Many friends do not know where to start when choosing an elevator. Looking at some keyword data searched by Baidu, netizens have a lot of questions about elevator price, configuration, and selection. In fact, elevators are also consistent with commodities such as automobiles and computers, that is, "demand determines configuration, and configuration determines price." Here, the editor of Sini tells us about the issues that we should pay attention to when buying elevators.

One, determine the ladder type

Because office buildings, hospitals, residences, and factories have different uses, the selected ladder types, configurations, and functions are often very different. At the same time, the passenger flow must be analyzed according to factors such as building area, floor, personnel flow, and elevator preset position in the building. , Determine the elevator speed, load, and number of elevators.

2. Elevator civil engineering drawings

After knowing the elevator type, load, speed, number of units, stops, and travel height, you can entrust the architectural design department to design the blueprint. At this time, the design department will draw the elevator civil engineering drawings based on the same type of standard civil engineering drawings provided by professional elevator manufacturers and combining different building elevator shafts.

Three, elevator specifications

Generally, elevators are sold by order and will be produced according to the specific requirements of customers. However, in the configuration of the hall, car door, car size and elevator specifications, try to choose standard products, because the standard size is uniformly manufactured and the cost is relatively low.

Take the 1000kg passenger elevator of Sini Electromechanical as an example, the standard should be:

The number of occupants is 13 people, the hall car door is in the form of a split door, and the hall door is 900mm wide and 2100mm high

The car size is 1600mm wide, 1400mm deep, and 2500mm high (can be made from 2300mm to 2500mm high)

For this, the civil construction dimensions of the hoistway are required to be 2200mm wide and 2300mm deep

The hall door opening is 1100mm wide and 2200mm high

Fourth, brand selection

When choosing an elevator brand, it is necessary to take time to review and inspect the manufacturer; require the manufacturer to produce business licenses, elevator manufacturing licenses, installation and renovation and maintenance licenses, corporate honors and bank credit and other relevant documents; in-depth understanding of pre-sales and after-sales Service commitment, warranty time, understanding of the required product status and performance, such as: the highest lifting height of the elevator, the maximum number of stops, special tools for maintenance, vulnerable spare parts, supply cycle, and the manufacturer's production volume for this type of product The implementation of elevator functions, the amount of elevators put into market use, etc., can be included in the inspection content, which directly reflect the comprehensive strength and production status of the manufacturer.

Five, understand the national standard

The current implementation is the implementation of the "Safety Code for Elevator Manufacturing and Installation" issued by the country on January 1, 2004. The document number: GB7588-2003 and the latest inspection regulation TSG_T7001-2016 elevator supervision and inspection and regular Inspection rules-traction and forced drive elevators. It specifies the implementation standards in detail, such as the horizontal dimension of the hoistway, vertical deviation, the minimum height of the top floor, the depth of the pit, and there must be no other pipelines in the elevator hoistway except for elevator equipment. Now for safety needs, it is stipulated that standard permanent lighting should be installed in the hoistway. The ventilation condition and lighting brightness of the machine room must meet the standards. The main power switch must be installed in a unified position. The load capacity of all areas must be met. The environmental requirements must be implemented and comply with the elevator national standard. standard. It provides a nationally unified technical basis and safety requirements for the manufacture, installation and inspection of passenger elevators and freight elevators. For the inspection before delivery of elevators, regular inspections, and inspections after major modifications or accidents, the new inspection regulations add regular Check to increase the balance coefficient, prevent accidental movement of the car (UCMP function), landing door type test mark, increase bypass device, door loop detection function, etc.

Six, price determination

The price of the entire elevator project should include: the price of the complete elevator equipment, transportation costs, taxes, installation fees, commissioning fees, inspection fees, one-year free maintenance fees and the manufacturer's commitment to the owner before and after sales warranty and other related costs. In addition, after the elevator is installed and passed the inspection and acceptance by the relevant national departments, some expenses need to be borne by the customer or user, such as elevator registration fee, installation acceptance inspection fee, fire protection (equipment) inspection fee, elevator annual inspection fee, etc. Both the supplier and the demander of the above expenses should be implemented into the contract as much as possible, and the responsibilities should be clearly defined to avoid disputes.

Seven, supply and payment

Supply: According to the construction progress (the roof is preferably capped, and the outdoor tower crane is about to be dismantled, to avoid storage and storage, secondary lifting, handling and other costs), the customer requires the manufacturer to specify the delivery date according to different ladder types and non-standard The general manufacturer’s lead time is 15-60 days.

Payment: The current payment method in the elevator market is generally to pay the full amount of equipment before shipment. Regardless of the payment method, the contract shall prevail. How to supply and pay should be strictly implemented in accordance with the contract, and corresponding penalty clauses should be given to the party who fails to perform.

Eight, elevator use registration

Before the special equipment is put into use or within 30 days after it is put into use, the user unit shall apply to the special equipment safety supervision department of the municipality or city divided into districts where the special equipment is located for registration of use, and the special equipment of the municipality or city divided into districts. The equipment safety supervision department may entrust its lower-level special equipment safety supervision department to handle the use registration; for special equipment that leaves the factory, it should generally go through the use registration before being put into use.
