TRACTION WITH A MACHINE ROOM (MR)
Ropes that pass over a wheel connected to an electric motor above the elevator shaft are used to lift traction elevators. They have substantially faster travel speeds than hydraulic elevators and are employed in mid- and high-rise applications. By balancing the weight of the car and its occupants so that the engine doesn’t have to move as much weight, a counter weight increases the efficiency of elevators.
Equipped Traction In elevators, the motor is connected to a gearbox, which turns a wheel that pulls the ropes. Up to 2mps can be reached by geared traction elevators. A geared traction elevator may move a maximum of about 75 metres
MACHINE-ROOM-LESS (MRL) TRACTION
In this configuration, the governor and controller are housed in a penthouse machine room right above the hoistway, together with a geared traction machine.
The use of this design has several advantages over hydraulic car types, including the potential to travel at an infinite distance and a superior power efficiency. Furthermore, no hydraulic oil is being used.
At our vendors’ production facility, the MR Elevator is made from premium raw materials. To assure quality and efficient operation, our personnel additionally test it on a number of aspects. The offered elevator is highly recognised for its distinctiveness and is available from us at a competitive price.
HYDRAULIC LIFTS
A piston at the bottom of a hydraulic elevator supports it and pushes it upward as an electric motor injects oil or another hydraulic fluid into the piston. A valve lets the fluid out of the piston, which causes the elevator to drop. With a top speed of 1 m/min, they are ideal for low-rise applications with 4 floors. On the lowest level, right next to the elevator shaft, is the machine room for hydraulic elevators.
A sheave that extends below the elevator pit’s floor receives the retracting piston when the elevator lowers in conventional hydraulic elevators. Some versions call for a shallower pit because they have telescoping pistons that collapse. The maximum travel distance is about 15 metres.
DUMBWAITERS LIFT
Food is transported using a freight elevator called a dumbwaiter lift. Dumbwaiters are a common feature in contemporary commercial, public, and residential structures. They go through a number of the same-structured stories.
In Chennai, dumbwaiter lifts are a great technique to move items from one floor to another within a building. They facilitate the movement of objects between floors by connecting to various floors across the building. They are employed by academic institutions, medical facilities, commercial businesses, and private businesses.
