Elevator performance depends on components responsible for stopping, holding, driving and ventilating the system.
Otis brake components, traction machines and fans contribute to these functions through machine braking arrangements, elevator movement systems and passenger ventilation arrangements.
Otis elevator brake components form part of the main machine brake assembly and are associated with stopping and holding functions within traction elevator systems. The range includes brake coils, brake drums, brake bars and brake pads used in selected machine brake arrangements.
| Brake Component | Available Variants |
|---|---|
| Brake Coils | Brake Coil (OEM: TAB330AJ1), 13VTR-150mm (OEM: DAA230E2), 18ATF, DZE-14 (OEM: DAA330K5), 17CT |
| Brake Drums | 13VTR, 17CT |
| Brake Bars | 17CT |
| Brake Pads | 13VTR (OTBM18, OTBM22), W1000, 19BT, 17CT, 18ATF |
Note: OTBM18 and OTBM22 are internal product reference codes used for identification and product selection purposes.
Otis elevator traction machines are electro-mechanical units that provide the power and motion required to raise and lower elevator cars and counterweights within traction elevator systems. Often described as the driving unit of the elevator system, they are associated with elevator movement and control functions.
Traction Machine Variants include 13VTR, 16VEC, 17CT and 18ATF.
Otis elevator fans are ventilation components designed to circulate air within the elevator car. Installed to support passenger comfort, these products assist with air movement inside selected elevator cabins.
Available product options include Fan for 17CT Machine.
| Product Category | Functions |
|---|---|
| Brake Coils | Control the electromagnet function within the main machine brake assembly. |
| Brake Drums | Form part of the brake assembly involved in stopping and holding functions. |
| Brake Bars | Support brake operation within selected machine brake arrangements. |
| Brake Pads | Provide the friction surface required for stopping and holding the elevator car and counterweight. |
| Traction Machines | Provide the power and motion required to move elevator cars and counterweights. |
| Fans | Circulate air within the elevator car to support passenger comfort. |
1. Why are ventilation fans installed inside elevator cars?
Ventilation fans circulate air within the elevator cabin to support passenger comfort during travel.
2. What keeps an elevator from moving when it is stopped?
The machine brake assembly is responsible for stopping and holding the elevator car and counterweight when required.
3. Why do elevators still need a brake if they already have a traction machine?
The traction machine provides movement, while the brake assembly is responsible for stopping and holding the elevator system.
4. What happens when braking force is released during elevator operation?
When braking force is released, the traction machine provides the motion required for elevator travel within the system.
