Traction lift
In a typical elevator, the car is raised and lowered by three to eight motor-driven wire ropes that are attached to the top of the car at one end, travel around a pair of sheaves, and are again attached to a counterweight at the other end.
The counterweight adds accelerating force when the elevator car is ascending and provides a retrading effort when the car is descending so that less motor hourse power is required. The counterweight is a collection of metal weights that is equal to the weight of the car & containing about 50% of its rated load. A set of chains are looped from the bottom of the counterweight to the underside of the car to help maintain balance by offsetting the weight of the suspension ropes.
Guide rails that run the length of the shaft keep the car and counterweight from swaying or twisting during their travel rollers are sometimes attached to the car and the counterweight to provide smooth travel along the guide rails.
Most elevators earlier used a direct current motor because it's speed can be precisely controlled to allow smooth acceleration and deceleration. Now a days AC Motors are frequently used and speed is typically varied using sophisticated ACVVVF Drives, which results in a accurate floor leveling of even fully loaded elevator. However in goods elevator choice of fitting ACVVVF Drive depends on cost benefit approach taken by client. The elevator controls vary the motor's speed based on a set of feedback signals that indicate the car's position in the shaftway. As the car's position in the shaftway. As the car approaches its destination, a sensor near the landing, signals the controls to stop the car at floor Level. Additional shaftway limit sensors are installed to monitor over travel & under travel.
Elevator Safety
Elevators are inherently safe. Their safety record, that of moving millions of passengers every day, without incident, is unsurpassed by any other vehicle system. The only way to get top performance and long life from equipments is preventive maintenance, which means regular inspection, adjustment and lubrication for elevators and escalators. These cares keep elevators operating at their best.
At TAJ, safety is of paramount importance and utmost care is taken to test/check all the critical components, sensors, controls & devices so as to derive maximum operational efficiency without failure, In order to make our elevator safe to ride we take care that all the mandatory and additional safety features are provided in all types of lift. Our team of dedicated engineers constantly analyze the breakdown pattern and pass it to the R & D team, which in turn use this information to further enhance & improve the riding quality, making TAJ elevators smoothest & safest.
