Detail introduction for above main accessories
1.Motor and controller:
The garage door operator is designed for residential overhead sectional and tilt doors.

The operator is equipped with a manual release lever which allows manual operation of the door in case of power failure.
The controller has a security LOCK function which prevents operation of the door from transmitter.
2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.

Bullish on your wallet
As it is now at a peak shopping period before the holiday, citizens will inevitably encounter queuing for payment when shopping. At this time, you must improve your vigilance and keep your wallets intact. Men should not put them in their pants pockets. If there are many people in line, you should pay attention to keeping a certain distance from the people around you. In the cases we handled in the past, some thieves used the opportunity of more people in front of the payment counter and often wandered in front of the cash register in some shopping malls. Pay the money, squeeze it up quickly, pretend to be paying money, wait for the opportunity to observe how much money is in your wallet, and where is your wallet. After finding out the situation, they will follow the trail and wait for the opportunity to start, so citizens must be optimistic about their wallets when paying, and do not arbitrarily put the wallet in the outer pocket or shoulder bag to avoid theft. In order to prevent shopping with a lot of cash, it is also a good choice to use bank credit card for consumption.
 Beware of "curtain pickpockets"
Due to the cold winter in our north, many shopping malls and supermarkets will have a thick curtain at the entrance to increase warmth. These places are often the places where thieves commit crimes. The so-called "curtain pickpocket" refers to some thieves who specifically use the opportunity of customers entering and leaving the mall to deliberately increase the chance of colliding with the victim, instantly pulling the customer's bag or using a blade to steal the victim's property. Therefore, citizens must increase their vigilance when entering and exiting shopping malls, and do not give criminals any opportunity to take advantage of. Those who drive and shop must park their car in a parking lot under security supervision, and do not leave large amounts of cash and valuables in the car.
Call the police once stolen
First of all, do n’t panic, and quickly notify the security staff of the store where you are, in order to find the thief in the shortest time, dial 110 to call the police in time. Now all major shopping malls and supermarkets have advanced monitoring equipment, which can record some situations in time to provide a real and effective basis for the police to solve the case.
