OEM/ODM China Lift Sheave - Passenger Traction Elevator Of Machine Roomless – Tianhongyi

Tianhongyi machine room less passenger elevator adopts the integrated high-integration module technology of the microcomputer control system and the inverter system, which comprehensively improves the response speed and reliability of the system. The suspension mode of the car is changed, the comfort of the machine roomless elevator is greatly improved, and the intensity of the installation and maintenance work of the machine roomless elevator is reduced. It breaks through the premise that the elevator must be equipped with a machine room, and provides a perfect creation for the limited space of modern buildings. Adopt the best parts and the most reasonable structural design plan, and effective shock and noise prevention technology to disperse and offset the irregular vibration of the car to achieve quietness and nature. Has higher flexibility, convenience and reliability. Suitable for residential, office buildings, hotels, shopping malls and other places.

1. Green and environmentally friendly, no special elevator machine room is needed, saving space and cost.

2. Low vibration, low noise, stable and reliable.

3. High efficiency and energy saving.

4. Easy to install and maintain.

1. Top-mounted traction machine: A specially designed and manufactured flat block traction machine is used to enable it to be placed between the hoistway top car and the hoistway wall, and the control cabinet and the top floor door are integrated. Its main advantage is that the traction machine and speed limiter are the same as those of the elevator with machine room, and the control cabinet is easy to debug and maintain; its main disadvantage is that the elevator’s rated load, rated speed and maximum lifting height are affected by the overall dimensions of the traction machine Constraints, the emergency cranking operation is complicated and difficult.

2. Lower-mounted traction machine: Place the drive traction machine in the pit, and hang the control cabinet between the car of the pit and the hoistway wall. Its biggest advantage is that increasing the elevator’s rated load, rated speed and maximum lifting height is not limited by the traction machine’s overall dimensions, and the emergency cranking operation is convenient and easy; its main disadvantage is that the traction machine and the speed limiter are under stress It is different from ordinary elevators, so improved design must be carried out.

3. The traction machine is placed on the car: the traction machine is placed on the top of the car, and the control cabinet is placed on the side of the car. In this arrangement, the number of accompanying cables is relatively large.

4. The traction machine and the control cabinet are placed in the opening space on the side wall of the hoistway: the traction machine and the control cabinet are placed in the reserved opening on the side wall of the hoistway on the top floor. Its biggest advantage is that it can increase the elevator’s rated load, rated speed, and maximum lifting height. It can be equipped with traction machines and speed limiters used in ordinary elevators. It is also more convenient for installation and maintenance and emergency cranking operations; its main disadvantages are , It is necessary to appropriately increase the thickness of the side wall of the hoistway reserved for openings on the top layer, and an overhaul door should be installed outside the opening of the hoistway wall.
