Elevator modernization (or lift modernisation) is the process of upgrading the critical parts of the elevator in order for it to be able to handle new technology, have better performance, improve safety, and even give the aesthetics an up-to-date appeal
Most elevators are built to provide about 20 years of service, as long as service intervals specified and periodic maintenance/inspections by the manufacturer are followed. As the elevator ages and equipment become increasingly difficult to find or replace, along with code changes and deteriorating ride performance, a complete overhaul of the elevator may be suggested to the building owners.
A typical modernization consists of controller equipment, electrical wiring and buttons, position indicators and direction arrows, hoist machines and motors (including door operators), and sometimes door hanger tracks. Rarely are car slings, rails, or other heavy structures changed. The cost of an elevator modernization can range greatly depending on which type of equipment is to be installed.
Modernization can greatly improve operational reliability by replacing mechanical relays and contacts with solid-state electronics. Ride quality can be improved by replacing motor-generator-based drive designs with Variable-Voltage, Variable Frequency (VVVF) drives, providing near-seamless acceleration and deceleration. Passenger safety is also improved by updating systems and equipment to conform to current codes.

With CEP traction elevator modernization, we use the existing elevator structure while
upgrading the ride quality and reliability with state-of-the-art
components. Upgrade to a CEP closed loop door operator or a sophisticated, energy saving VVVF inverter.
CEP traction elevator modernization can include:

Benefits of elevator modernization
Orchard should pay attention to the use of pesticides in spring
Spring is the initial stage of germination of various pests and diseases in orchards. In this period, the number of pests and diseases is small, and it is easier to control. Doing a good job in the prevention and control of various pests and diseases of spring fruit trees can greatly reduce the risk of prevention and control in summer and autumn, and lay a good foundation for the high yield of fruit trees in that year. It is very important to accurately use pesticides in fruit tree production.
What should you pay attention to when using orchard Before purchasing pesticides, it is necessary to clarify the target of prevention and treatment and the target of concurrent treatment. Pay attention to the following points when purchasing pesticides, so as not to buy fake drugs and cause losses. First, the pesticides purchased must have four certificates: pesticide registration certificate, production license, pesticide standard number, and product certification. For those who are incomplete in the four cards, it is necessary to prevent "counterfeiting". The second is to pay attention to the effective period of pesticide use. Generally, the effective period of the pesticide is 1 year, the powder is 2 years, and the emulsifiable oil is 3 years. You can look at the production date and validity period of the trademark in detail. The third is to look at the pesticide packaging, it should be intact without damage and no leakage, the powder pesticide does not agglomerate, the emulsion pesticide has no stratification, the water pesticide does not precipitate, the granular pesticide meets the standard, and the particle size is well-proportioned. Fourth, it is best to choose a pesticide with multiple effects (multi-effect) to achieve a multi-drug effect.
Pesticide placement: Pesticides are toxic to humans, poultry, etc. They must be stored separately and separated from food, human, livestock and clothing. It is best to have separate pesticide storage rooms and storage boxes to avoid causing human or livestock ingestion or chronic poisoning. .
Proper and reasonable mixing of pesticides can improve efficacy, treat several pests and diseases, reduce the amount of drugs, reduce costs, and sometimes improve drug efficacy, reduce toxicity, reduce the resistance of pathogenic pests to chemicals, or control resistant pests. .
Some pesticides are mixed in advance by the factory and mixed with water. Liquid dosage forms such as emulsifiable concentrates and wettable powders can be mixed and used.
Pesticide blending should have a clear purpose. The principles followed include: reasonable cost, without affecting the chemical stability of the active ingredient and not destroying the physical properties of the agent. The toxicity is not increased after mixing, and the toxicity and residue are not higher than the single agent. The efficacy of the drug is reasonable, one must treat different pests and diseases; the second is to have synergistic effect, and at the same time actively promote the use of pesticide synergists, such as multi-functional plant synergists; the third is to pay attention to the cooperation of different modes of action. Most mixed pesticides should be used as needed. For new mixed formulations, they must be tested before use.
Note that pesticides are forbidden to be mixed in the following cases: when the alkaline substance is easily decomposed and the effect is reduced, or even the pesticide is ineffective, it cannot be mixed with alkaline pesticides. For example, phoxim, pyrethroids and the like cannot be combined with the stone sulfur mixture. Alkaline agents such as Bordeaux mixture are used in combination. Mixtures that have a destructive effect on the emulsion after mixing cannot be mixed. Organic sulfur and organophosphorus pesticides cannot be mixed with pesticides containing copper preparations. Microbial-derived insecticides and systemic organophosphorus pesticides cannot be mixed with fungicides.
In addition, we must pay attention to the safe interval of pesticide use. The safety interval is the period from the last application to the harvest (harvest) of the crop, from the time it takes to the time it takes for the residue to fall below the safety standard. The use of pesticides in orchards must be greater than the safe interval between the last spray and harvest to prevent human and animal poisoning.
