Dear Respected Customers,
With reference to this subject i.e. Lifts/Elevators and Escalators we want to share something with you which is "VERY VERY IMPORTANT" before coming to any decision. We all are responsible citizens of our society. So, this is responsibility of each and every responsible citizen that his or her decision is good for the society or good for our family, friends and everyone around ourselves. We know that "Lift/Elevators and Escalators are life risk Product" so we have to choose our product VERY CAREFULLY.
If we search with Google for "Lift/Elevator and Escalatoraccidents occurred in India" then we can see that lot of accidents are occurring in our country just due to carelessness in choosing a good product OR due to lack of knowledge OR due to lack of awareness.
So we want to request you before choosing any product please be aware, be careful and having good knowledge of lift/elevators. Here we are providing you certain information which is for your reference and knowledge. For this kindly go through the picture given in this picture each and every details of a lift and Escalator installation is given.
As all of us know Not a single company is available which makes every component of an elevator or escalator in house. Each and every company in the market choose or purchase some OR all components from others. That is why it is said that lift and escalator is a tailor made product. We the people of Abattis cares for you and our society that is why we never compromise with international safety norms and quality of material used in the product. We the people of Abattis always give importance to value of life. We choose components which are best in its class. That is why we provide

1. Lift Well OR Lift Shaft

Lift Well OR Lift Shaft is the space provided in any building from lowest floor to topmost floor for installation of Lift/Elevators. The space is just like a hollow square pipe connecting all the floors of the building. It can be made up of Concrete, Brick Wall or Steel Structure depending upon customers use and design of building. Only thing to ensure that the shaft must be straight and clear inside throughout from bottom to top. Lifts (or elevators) in buildings are normally totally enclosed by a shaft (typically square or rectangular) that will rise vertically through the building and often terminate above roof level. Lift shafts will also extend below ground if they must serve one or more basement levels, or to house operating equipment. They are commonly found in commercial, public and other types of multi-storied building.

2. Limit Switches in a lift

Limit Switches are one of the major safety devices for an Elevator/Lift. There are Four or Six nos. of Limit Switches installed in the Shaft depending upon the technology of Controller. These Limit Switches can be NC OR NO again depending upon Controller of Lift/Elevators. First Limit Switch installed at top of the Shaft i.e. in Over Travel space of Lift Shaft. This limit is known as UP FINAL Limit. Second limit switch installed just below the First Limit Switch and is Known as UP DIRECTION LIMIT. Third from the top is known as SLOWING LIMIT for reaching Topmost Floor installed at mid point of Top Floor. Fourth from the top is SLOWING LIMIT for reaching Ground Floor OR Bottom Most Floor installed at mid point of Bottom Most Floor. Fifth Limit from Top is DN DIRECTION LIMIT installed in the pit of lift shaft. Sixth and the Final is DN FINAL LIMIT installed in the bottom of the lift shaft i.e. in PIT of lift shaft.

3. Over Speed Governor( O. S. G. )

O. S. G. OR OVER SPEED GOVERNOR is a safety device that comes into operation when the lift car exceeds its permitted speed. If the lift car exceeds its rated speed upon descent, the over speed governor trips when its tripping speed is reached and triggers the safety gear on the lift car via the governor rope. Over speed governors include a switch that opens when the elevator reaches a predetermined velocity such as 110% of rated speed. When the switch opens, power is removed from the machine motor and brake. Typical governor designs include a sheave coupled to a rope attached to the elevator car. The tripping assembly actuates a mechanism to stop the governor rope. Braking of the governor rope causes the safeties to be engaged and thereby stop the car. In more recently developed "Machine Room-Less" elevator systems, where the conventional machine room is eliminated, the governor and various other components are located in the hoistway. With the governor in the hoistway, the task of accessing and resetting a governor over speed switch is time-consuming, complicated, and costly. Although a solution may be to provide a special door or hatch to access a governor in a hoistway, such a solution adds cost and space requirements. However, some MRLs may instead provide a switch in the cabinet to reset the governor automatically.

4. Safety Gears OR Safety Teeth ( Car Frame )

ELEVATOR SAFETY GEARS is the part of elevator, which is the safety protection device for protecting elevator runs safely. Elevator safety gear is operated by elevator over speed governor, the function is that stops the elevator car and holds the elevator car at the elevator guide rail in an emergency when the running speed of elevator car exceeds the set speed by elevator over speed governor, or elevator suspension rope is in broken or loose situation. Elevator safety gear provides effective protection for elevator running in safe; usually it is installed on the elevator car or counterweight frame.
Safety gear is a mechanical device for stopping the car (or counterweight) by gripping the guide rails in the event of car speed attaining a pre-determined value in a downward direction of travel, irrespective what the reason for the increase in speed may be.
