Rope Wheel Tension Device For Passenger / Freight Elevator SN-SG-ZJ300A
Elevator Tension Device
The Tension Device is a crucial component in elevator systems, ensuring proper rope or belt tension for safe and efficient operation. It maintains consistent friction between the traction sheave and suspension media (steel ropes or flat belts), preventing slippage and wear.
Counterweight Tension: Adjusts counterweight position to balance load variations.
Rope/Belt Tensioners:
Mechanical: Uses springs or weights to auto-adjust tension.
Hydraulic/Pneumatic: Provides precise control for high-speed elevators.
Compensation Chains/Cables: Compensates for rope length changes due to temperature or load.
Safety: Prevents rope slack (which can derail cars) or over-tension (causing premature wear).
Compliance: Meets EN 81-20/50 and ASME A17.1 standards.
Maintenance: Requires periodic inspection for alignment, corrosion, and tension accuracy.
This device rope wheel specification can be according to the specifications and the elevator overspeed governor matching actual use status,easy to install, applicable compact layout of the elevator structure requirements.For the use of various specifications of balancing selection, specific use state table.
This device needs to clear the following parameters:rope wheel, weight, quality, specifications, match, wire rope, and matching of guide rail type, etc.
| Category number | Rope wheel dlameter | Match the steel wire rope | Quality of balancing | Applicable state |
| A01 | 200 | Φ6/Φ6.3 | 18kg | H≤50m |
| A02 | 30kg | 50m≤H≤100m | ||
| A03 | 240 | Φ6/Φ6.3/Φ8 | 18kg | H≤50m |
| A04 | Φ8 | 30kg | 50m≤H≤100m |
FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements. Configuration is not only for wire rope and rated load, but also considered the size of the traction, as a result, the tensile strength of wire rope is greater than the weight of the lift. The safety factor is equipped with more than four wire rope. So it won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator running?
If it occurs, the elevator will automatically stop due to the electrical and mechanical safety device. In case of power failure,elevator brakes will automatically taken. In addition, the power supply departments such as planned outage, prior notice are also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of elevator will automatically restart without any danger. With anti clamping switch, once the gate touched, this switching action make the elevator unable to be closed and even reopened. In addition, closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the (tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily proportional to the operation complexity. Therefore, escalators designed by us apply an integrated structure, so that the equipment is more precise and more efficient and allows easier and more convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
