Home > FAQ(Frequently Asked Questions)

Can you offer OEM service to customer?

Yes, we could provide OEM service to customers; printing your LOGO and model number on products.

How do you deal with the sample to the customer?

In general, if the customer needs the sample, they are required to pay the sample by T/T or Wenstern Union in advance. The sample cost can be deducted in the first purchasing order.

How about your quality warranty?

We provide quality warranty for all of elevator products. All the parts could be changed for you freely if there is any problem during the warranty period.


An elevator or lift is a vertical transport equipment that efficiently moves people or goods between floors of a building, vessel or other structure. Elevators are generally powered by electric motors that either drive traction cables and counterweight systems like a hoist, or pump hydraulic fluid to raise a cylindrical piston like a jack.
How to use elevator? It is very simple. When the elevator door is oepn, people go into the elevator cabin and choose the floor he wants to go by pushing button. Elevator will move to the correct floor, stop and open door.
Because of wheelchair access laws, elevators are often a legal requirement in new multi-story buildings, especially where wheelchair ramps would be impractical.
Elevator is more popular in the modern society.

Lift design

Some argue that lifts began as simple rope or chain hoists. A lift is essentially a platform that is either pulled or pushed up by a mechanical means. A modern day lift consists of a cab mounted on a platform within an enclosed space called a shaft or sometimes a "hoistway". In the past, lift drive mechanisms were powered by steam and water hydraulic pistons. In a "traction" lift, cars are pulled up by means of rolling steel ropes over a deeply grooved pulley, commonly called a sheave in the industry. The weight of the car is balanced with a counterweight. Sometimes two lifts always move synchronously in opposite directions, and they are each other's counterweight.
The friction between the ropes and the pulley furnishes the traction which gives this type of lift its name.
Hydraulic lifts use the principles of hydraulics to pressurize an above ground or in-ground piston to raise and lower the car (see Hydraulic elevators below). Roped hydraulics use a combination of both ropes and hydraulic power to raise and lower cars. Recent innovations include permanent magnet motors, machine room-less rail mounted gearless machines, and microprocessor controls.
The technology used in new installations depends on a variety of factors. Hydraulic lifts are cheaper, but installing cylinders greater than a certain length becomes impractical for very high lift hoistways. For buildings of much over seven stories, traction lifts must be employed instead. Hydraulic lifts are usually slower than traction lifts.
Lifts are a candidate for mass customization. There are economies to be made from mass production of the components, but each building comes with its own requirements like different number of floors, dimensions of the well and usage patterns.

Elevator Door

Elevator doors protect passengers from falling into the shaft. The most common configuration is to have two panels that meet in the middle, and slide open laterally. In a cascading configuration, the doors run on independent tracks so that while open, they are tucked behind one another, and while closed, they form cascading layers on one side. This can be configured so that two sets of such cascading doors operate like the center opening doors described above, allowing for a very wide elevator cab. In less expensive installations the elevator can also use one large "slab" door: a single panel door the width of the doorway that opens to the left or right laterally. Some buildings have elevators with the single door on the shaft way, and double cascading doors on the cab.

Push Button

 Push button (also called pushbutton) is a simple switch mechanism for controlling some aspect of a machine or a process. Elevator push buttons is used for choosing floor or calling elevator.Buttons are typically made out of hard material, usually plastic or metal or two of them. The surface is usually flat(some are concave or protuberant) or shaped to accommodate the human finger or hand, so as to be easily depressed or pushed. Buttons are most often biased switches, though even many un-biased buttons which due to their physical nature require a spring to return to their un-pushed state. Different people use different terms for the "pushing" of the button, such as press, depress, mash, and punch.Elevator buttons have LED inside,it is generally red or blue light.
