General Elevator Tension Device OX-200: Stable Tension Core from Nanjing Zhuye Elevatorparts

The General Elevator Tension Device OX-200 is a critical tension adjustment component for elevator traction systems, specifically designed to maintain stable tension of elevator traction ropes or belts. As the “tension stabilizer” of the elevator transmission system, it automatically adjusts the tension of the traction medium according to the actual operating conditions, ensuring uniform force on each rope/belt, avoiding slipping or excessive wear, and thus guaranteeing the stable and safe operation of the elevator car. The General Elevator Tension Device OX-200, exclusively supplied by Nanjing Zhuye Elevatorparts (a professional and trusted distributor of high-quality elevator components), fully complies with international elevator safety standards (EN 81-20, GB 7588) and is universally compatible with most elevator brands and traction system models. Featuring precise tension adjustment, strong load-bearing capacity, and durable structure, this tension device provides reliable operational guarantees for elevators in residential buildings, commercial complexes, office towers, hospitals, and other scenarios worldwide.

Nanjing Zhuye Elevatorparts adheres to the core philosophy of “safety first, quality-oriented” and implements strict quality control over the General Elevator Tension Device OX-200. Each device undergoes a multi-stage pre-delivery inspection, including tension adjustment accuracy testing, load-bearing capacity verification, corrosion resistance detection, and mechanical life trials. The product adopts high-quality carbon steel (Q235) for the main frame, high-precision tension springs, and wear-resistant nylon guide wheels: the carbon steel frame is subjected to anti-rust treatment (electrophoretic coating), ensuring excellent corrosion resistance in the humid shaft environment; the high-precision tension springs have stable elastic performance, with an elastic coefficient error ≤ 2%, realizing precise tension adjustment; the wear-resistant nylon guide wheels reduce friction with the traction rope/belt, extending the service life of both the device and the traction medium. Its standardized installation interface and adjustable structure make it seamlessly compatible with the OX-200 dedicated mounting positions of most general-purpose elevator traction systems, eliminating the need for complex modifications.

Step-by-Step Usage Guide for General Elevator Tension Device OX-200

To ensure the reliable operation of the elevator’s traction system and extend the service life of the OX-200 tension device, follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for installation, adjustment, and maintenance:

1. Professional Installation & Calibration

Installation must be performed by certified elevator technicians familiar with elevator traction systems. Prior to installation, confirm the compatibility of the device with the target elevator’s traction system model and traction rope/belt specifications using the detailed compatibility manual provided by Nanjing Zhuye Elevatorparts. The steps are as follows:

Safety Preparation: Cut off the elevator’s main power supply and fix the elevator car to a safe position (top or bottom of the shaft) using a safety clamp. Enter the shaft and locate the tension device mounting position (usually at the bottom of the traction rope/belt). Clean the installation area to remove dust, oil stains, and debris that may affect installation accuracy and fixation.
Device Installation: Fix the OX-200 tension device’s main frame to the dedicated mounting bracket in the shaft using high-strength bolts provided by Nanjing Zhuye Elevatorparts. Ensure the frame is installed vertically (tilt angle ≤ 3°) to avoid affecting the normal operation of the tension adjustment mechanism. Install the traction rope/belt onto the device’s guide wheels, ensuring the rope/belt is properly aligned with the guide wheel groove (no deviation or edge contact).
Tension Calibration: According to the elevator’s rated load and traction system parameters (provided by the elevator manufacturer and Nanjing Zhuye’s technical guidance), adjust the tension adjustment bolt of the OX-200 device. Use a professional tension tester to measure the tension of each traction rope/belt, ensuring the tension value is within the standard range (usually 8–12 kN, depending on the rope/belt specification) and the tension difference between each rope/belt is ≤ 5%. After adjustment, lock the tension adjustment bolt with a lock nut to prevent loosening due to elevator vibration.
Post-Installation Testing: Restore the power supply and conduct comprehensive functional tests. Operate the elevator to run up and down at normal speed and rated load, check the operation state of the OX-200 device (no abnormal noise, stable tension adjustment); observe the traction rope/belt for slipping, deviation, or abnormal vibration. Use the tension tester again to recheck the tension value after operation, ensuring no obvious changes. If there is abnormal noise, tension deviation, or rope/belt slipping, recheck the installation and tension adjustment immediately.

2. Daily Operation & Routine Inspection

Regular inspections are crucial to early detection of tension device faults and ensuring the safety of the elevator traction system. Maintenance personnel should incorporate the following checks into their daily patrols:

Daily Visual Inspection: During shaft patrols, check the external state of the OX-200 tension device. Ensure the main frame is free of deformation, rust, or cracks; the tension adjustment bolt and lock nut are tight with no looseness; the guide wheels rotate smoothly (no jamming) and the wheel groove is free of severe wear or damage; the traction rope/belt is properly attached to the guide wheel groove.
Weekly Functional Check: Operate the elevator to run through the full stroke, listen for abnormal noise (such as friction or collision) from the tension device area. Check the tension indicator (if equipped) to confirm the tension value is within the normal range. Observe the movement of the tension device during elevator operation, ensuring it can freely adjust with the traction rope/belt’s stretch and contraction.
Monthly Parameter Monitoring: Use a professional tension tester to measure the tension of the traction rope/belt and the operation state of the OX-200 device. Clean the guide wheels, tension springs, and adjustment mechanism with a dry, lint-free cloth to remove dust and oil stains. For elevators in harsh environments, apply a small amount of special anti-rust lubricant (provided by Nanjing Zhuye Elevatorparts) to the adjustment bolt and guide wheel shaft to prevent rust and jamming.

3. Regular Maintenance Schedule

Systematic maintenance can effectively extend the service life of the General Elevator Tension Device OX-200. Follow Nanjing Zhuye Elevatorparts’ recommended maintenance plan:

Quarterly Maintenance: Disconnect the power supply, remove the traction rope/belt from the guide wheels (if necessary), and thoroughly clean the guide wheels, wheel shafts, and tension springs. Inspect the guide wheels for wear (replace if the wheel groove depth is reduced by more than 1mm) and the tension springs for fatigue or deformation (replace if elastic performance is reduced). Recheck and tighten all fixed bolts and lock nuts.
Semi-Annual Performance Test: Conduct a comprehensive performance test, including tension adjustment accuracy, load-bearing capacity, and guide wheel rotation smoothness. Use a professional tension tester to simulate different load conditions and verify the device’s tension adjustment stability. For elevators in high-traffic areas (e.g., shopping malls, airports) or harsh environments (high humidity, dust), increase the test frequency and check the traction rope/belt for wear that may affect the device’s operation.
Annual Professional Overhaul: Arrange a professional inspection with Nanjing Zhuye Elevatorparts’ certified technical team. Disassemble the OX-200 device (by professional personnel) to inspect internal components (such as springs, bearings, and adjustment mechanisms) for aging or damage. Replace worn components with genuine parts. Recalibrate the tension adjustment accuracy to meet the original factory performance standards and the elevator’s actual operating requirements.

Recommended Replacement Cycle for General Elevator Tension Device OX-200

As a core tension adjustment component bearing long-term tension load, mechanical wear, and environmental erosion, the General Elevator Tension Device OX-200 has a specified service life. Timely replacement is critical to avoiding device failure (such as spring fatigue, guide wheel jamming, or tension adjustment failure), which may lead to uneven tension of the traction rope/belt, slipping, or even breakage—resulting in elevator operation failure or serious safety accidents.

1. Standard Replacement Cycle

Under normal operating conditions (elevator daily operation time 12–24 hours, daily running distance ≥ 100km, shaft environment temperature -10–60℃, humidity 10%–95%), the recommended replacement cycle for the General Elevator Tension Device OX-200 is 4–6 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field data, including spring fatigue tests, guide wheel wear analysis, and actual operation feedback.

2. Adjustments for Special Scenarios

Harsh Environments: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust construction sites, or elevators with frequent high-load operation (rated load ≥ 80% for long periods), the replacement cycle should be shortened to3–4 years. Harsh conditions accelerate the rust of the main frame, fatigue of the tension spring, and wear of the guide wheels, significantly reducing the device’s reliability.
Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and clean, stable shaft environments, the replacement cycle can be extended to 6–8 years—only if Nanjing Zhuye’s professional inspection confirms that the device’s tension adjustment accuracy, spring performance, and guide wheel operation are all intact.

3. Immediate Replacement Conditions

Replace the General Elevator Tension Device OX-200 immediately if any of the following issues occur, regardless of service life:

The tension spring is severely fatigued, deformed, or broken, leading to inability to adjust tension or large tension deviation (exceeding 15% of the standard value).
The guide wheels are severely worn (wheel groove depth reduced by more than 1mm), cracked, or stuck, causing abnormal wear or deviation of the traction rope/belt.
The main frame is severely rusted, deformed, or cracked, failing to bear the rated tension load and posing safety hazards.
The tension adjustment mechanism is stuck or ineffective, and the tension value cannot be adjusted to the standard range even after maintenance; the device cannot freely move with the traction rope/belt’s stretch and contraction.

In conclusion, the General Elevator Tension Device OX-200 supplied by Nanjing Zhuye Elevatorparts is a high-quality, universally compatible tension adjustment component tailored for elevator traction systems.
