The traction machine, which is housed in the rooftop machine room, operates the rope elevators. Both gear- and gearless traction machine types exist. By using the most recent inverter control, the gearless-type traction machine provides smoother acceleration and deceleration than the geared-type traction machine, which employs a reducer.
Additionally, gearless-type traction machines significantly advanced energy economy and comfort while also helping to reduce the size of equipment in the machine room.
The most prevalent kind of elevators are traction elevators, sometimes referred to as electric elevators. Rolling steel ropes over a pulley with deep grooves, referred to as a sheave in the industry, is how elevator cars are raised. A counterbalance serves to balance the car’s weight.
A pair of elevators may be constructed so that their cars always travel simultaneously in opposite directions and act as a counterbalance to one another. Electric motors with AC or DC power supply power geared traction equipment. As the name suggests, the hoisting sheave is turned by a worm-and-gear reduction unit that is driven by an electric motor in this configuration.
The gear reduction has the advantage of requiring a less powerful motor to turn the sheave, despite the fact that lift rates are slower than in a standard gearless elevator.
Five to eight lengths of wire cable, referred to as hoisting ropes, are attached to the top of the elevator in a gearless traction machine and are wrapped in certain grooves around the drive sheave. The opposite ends of the cables are fastened to a counterweight that is mounted on its own guide rails and can be raised and lowered within the hoistway.
The cables are forced into the drive sheave’s grooves by the combined weight of the elevator car and counterweight, which creates the necessary traction as the sheave rotates.
The counterweight is designed to equal the weight of the automobile and a half-load of people in order to lessen the burden on the motor. The counterweight lowers as the car rises, balancing the burden. This saves energy because the motor only needs to raise up to half a pound of weight.
The Global Elevator Traction Machine market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Traction elevators are now the most popular kind of elevator because of the exponential growth in demand for them in the modern world. the greatest and most dependable suppliers of elevator traction machines, offering cutting-edge innovations at affordable prices.
Sheaves, which are rolling steel ropes, are used to pull elevator cars, while a counterweight balances the car’s weight. They feature faster travel rates than hydraulic elevators and are ideal for use in both mid- and high-rise buildings.
Lift Tec Engineers, a reputable company, has produced and supplied elevator traction equipment. whole selection of machines is of the highest calibre since they are made with the best metals and alloys available.
An international manufacturer of elevator parts is called APSON. With the goal of meeting the needs of the elevator industry by creating the safest and most luxurious line of power-efficient elevator traction machines. To accommodate the needs of any location, Hitachi has created a wide variety of modernisation packages.
In order to ensure a secure and comfortable environment for all elevator and escalator users, Hitachi wants to continue providing adaptable choices for modernising existing elevators and escalators that satisfy a variety of client needs.
The traction hoisting machine is positioned either on the top side wall of the hoistway or on the bottom of the hoistway in machine room less elevators, which lack a fixed machine room at the top of the hoistway.
A permanent magnet is used to install the motor, “sticking” it in place permanently and enabling Variable Voltage Variable Frequency (VVVF) drive operation. In place of traditional induction motors, certain hoisting machines employ gearless synchronous motors.
This layout avoids the requirement for a dedicated machine room, saving a significant amount of construction area. Gearless traction elevators make up the majority of MRL elevators. The primary controller is located on the top floor close to the landing doors, while the hoisting motor is situated on the hoistway side wall.
