Monitoring System

Another part included elevator accesories is monitoring system. Elevator monitoring system installed to monitor elevator status, when elevator run, stop, idle, error or another status monitored from elevator monitoring system. This monitoring system installed on the security or building management system, all of elevator status will be recorded in monitoring system, when the building management need this data to check elevator performance they can take from this elevator monitoring system.
Elevator monitoring system now use interested monitor to appear elevator status, data storage and another tools can make building management easy to check elevator performance.

Elevator Accesories

Elevator have some parts that look like not to important but it must be installed, because without this parts elevator can be scarried things. When the passenger trapped this device will verry usefull for passenger for their safety, or when the electrical power elevator gonna blackout this device will do save the passenger from trapped on the elevator.

Landing Door

Elevator have two door, car door and hoistway door. there are sliding door type that is mechanically coupled to the car door when the car is at landing door. Hoiistway and car door are opened and closed in unison by the door operator mounted on the top of car elevator. Both door opened and unlocked by vane located at the car door, the lock type is mechanical and electrical lock switch.

Brake

The most importannt part in elevator is brake. Brake is a pair of shoes that apply equal and opposite pressure to a drum (motor elevator drum), puley or a disc mounted on the motor shaft. Elevator brake is made up of a compressive spring assembly, brake shoes with linings, and a solenoid assembly. When the solenoid is not energized, the spring forces the brake shoes to grip the brake drum and induce a braking torque. The magnet can exert a horizontal force for the break release.To stop and hod the car movements when the power is lost used spring clamp. Spring clamp will push back the shoe brake to making fail safe stops and holds the car when power is lost. In order to improve the stopping ability, a material with a high coefficient of friction is used within the breaks, such as zinc bonded asbestos. A material with too high a coefficient of friction can result in a jerky motion of the car. This material must be chosen carefully.

Roller Guide

Roller, one of elevator part, located on the car lift even in counterweight, four set roller each car elevator and four on counterweight. Each roller guide comprises three rubber tired roller wheels mounted on the stand, two side for front and one for side to side. front roller to front-rear aligment and side roller to side-side aligment.
The roller guide are classified by the diameter of ts wheels, roller have vary diameter.The rolling action of the roller reduces friction and noise and eliminates the guide rails lubrication.
The larger diameter of rollers are the smoother the ride, the selection of roller determined by the speed and duty load of the car.

Controller

An elevator system completed by controller position in the machine room, this controller performs some functions are operational control and motion control.
Operational controller stores the location of calls, reset answered calls, and initiates door operation to open and closes. This function allow to communicates with
passenger even in emergency condition or other condition by signaling that the calls has been received (registered), providing car position information and providing audible and visual indication of elevator direction or when the car travel arrive at the landing position.
This controller powered by three phase alternating current providing by building owner, and providing maiin line disconnect switch located in the near of controller
