An elevator compensation chain is a balance component that offsets the changing weight of the hoist ropes in a tall elevator, and the Chenxing full plastic compensation chain is the all-PVC, cable-form version built for medium- and high-speed lifts. It runs quietly without lubrication, resists flame and low temperature, and is supplied across a reference range from about 1.12 kg/m to 5.68 kg/m with breaking loads up to 62.6 kN.
Why does an elevator need a compensation chain at all? In a tall building the hoist rope weight changes as the car travels. At the top floor the rope weight sits mostly on the counterweight side, and at the bottom floor it sits mostly on the car side. The compensation chain hangs between the car and the counterweight and balances that changing rope weight as the car moves. Without it the elevator works against a moving imbalance, the drive system works harder, and the ride becomes rough.
The full plastic chain is built as one continuous PVC composite cable, not a metal chain with a sleeve. That structure gives it three practical advantages for a modern lift: it bends with a small radius so it follows the guide arrangement cleanly, it runs almost silently, and it never needs lubrication. The PVC body is compounded for flame resistance and low temperature service, which matters in a hoistway that can be cold in winter and warm in summer.
Positioning in short:

This balance component is a small part, but it sits inside every tall elevator, and it is sold and shipped from the Chenxing factory with the same documentation and after-sales support as a full machine. The wider machinery range is listed in the full machinery catalogue and the company introduction.
The full plastic compensation chain is supplied as a PVC composite cable with a round cross section. The structure is one continuous body, which is why the chain keeps its shape, returns to a straight line after coiling, and does not develop the separate-link noise of a metal chain.
Reference characteristics of the full plastic chain:
Cable form: solid PVC composite body, no inner metal links, no lubrication points
Bending behavior: small minimum bending diameter, reference value 610 mm across the range, so the chain follows the guide sheave cleanly
Fire behavior: PVC body compounded with flame retardant properties
Cold behavior: suitable for low temperature operation, common reference range about -20 C to +60 C, some references state -15 C to +60 C
Noise: quiet running, a direct replacement for old rope-type chains
Maintenance: none, no oil or grease required in normal service
Fitting: supplied in coils, cut to length at installation
The table below is taken from industry published reference values for the WFSZ / WFZQ style full plastic series. Every figure is a typical industry reference value with the stated tolerance, and the final specification is confirmed at enquiry.
| Specification | Unit weight (kg/m) +/- 0.2 | Outer diameter (mm) +/- 1.5 | Min. bending diameter (mm) | Breaking load (>= kN) |
|---|---|---|---|---|
| 075 | 1.12 | 24 | 610 | 11.25 |
| 100 | 1.49 | 29 | 610 | 13.32 |
| 120 | 1.88 | 31 | 610 | 18.00 |
| 150 | 2.24 | 35 | 610 | 23.66 |
| 200 | 2.98 | 38 | 610 | 29.97 |
| 250 | 3.72 | 42 | 610 | 40.82 |
| 300 | 4.46 | 45 | 610 | 46.58 |
| 350 | 5.20 | 49 | 610 | 53.40 |
| 400 | 5.68 | 52 | 610 | 62.60 |
The reference number is a weight class, not a length. 075 means about 1.12 kg/m, 400 means about 5.68 kg/m, and the middle sizes cover the common passenger lift range.
The right size depends on the hoist height and the car and counterweight arrangement. Taller hoistways carry more rope weight and need a heavier chain class.
The minimum bending diameter is 610 mm for the whole reference range, which simplifies the guide sheave layout.
Speed is a selection factor, not a fixed rating. The full plastic chain fits medium and high speed elevators, and the final size is confirmed against the actual speed, hoist height and travel profile at enquiry.

Medium and high speed passenger lifts. This is the main territory of the full plastic chain. Industry references place the all-PVC chain at about 1.75 m/s and above, with published ranges up to 3 to 3.5 m/s and wider references to 4 to 6 m/s. At those speeds the balance chain must be quiet and free of periodic noise, and the solid PVC body delivers both.
Tall residential and office buildings. The balance function matters most when the hoistway is tall, generally 30 m and above. The full plastic chain cancels the rope weight difference as the car moves, so the ride stays even from the ground floor to the top floor.
| Application | Elevator type | Why the full plastic chain fits |
|---|---|---|
| Passenger elevators | Medium and high speed lifts, about 1.75 m/s and above | Quiet cable body, no link noise at higher speed |
| Residential high rise | Tall hoistways in apartment buildings | Even balance over the full travel, low maintenance |
| Office and hotel buildings | Frequent service lifts | Smooth, quiet ride for passengers |
| Medical elevators | Hospital lifts with smooth travel requirements | Low noise and low vibration help patient comfort |
| Vehicle elevators | Parking lifts with heavy load | Solid PVC body with the reference breaking load range |
| Construction elevators | Temporary and permanent site lifts | Flame retardant PVC body for safety sensitive sites |
How it behaves in service. The chain hangs between the car and the counterweight and follows the guide sheave at the bottom. Because it is one continuous PVC cable, it does not whip or knock against the guide arrangement the way a link chain can. The small bending diameter lets it run on a compact sheave, and the flame retardant body is a sensible choice for a hoistway environment.
The Chenxing factory builds the machines that produce this class of PVC profiles and cables, shown on extruder, profile extrusion line, Profile Extrusion Line Solution and board sheet extrusion line.
The full plastic chain is supplied to the specification of each lift project, and the reference range is the starting point.

Weight class. The unit weight is selected from the reference range to match the hoist height and the rope arrangement.
Outer diameter. The diameter class follows the selected weight, with the reference values as the basis.
Flame retardant grade. The PVC compound grade is selected for the project requirement and confirmed at enquiry.
Color and marking. Coils can be marked with length, weight class and batch information for site tracing.
Packaging and labelling. Export packing and marking follow your shipping instructions.

Installation guidance. Chenxing provides installation guidance covering the two points that cause most site problems.
The installation points that matter. Before hanging, the chain should be allowed to relax and clear the spiral and twist that build up during coiling. Common practice is to hang one end under the car, run the car slowly to the top, cut to length, leave the chain hanging statically with the tail section more than 1 m above the floor for about 24 hours, then connect the other end and check again after a few days of running. The guide device center line should line up with the suspension point on the same vertical line, and the guide device should sit about 1 m above the lowest bend of the chain so the bending radius is not forced too small. The suspension device should allow the chain length to be adjusted and act as a secondary safety point.

It is a balance chain made as one continuous PVC composite cable, with no inner metal links. It hangs between the elevator car and the counterweight and balances the changing hoist rope weight during travel.
Because it runs quietly, needs no lubrication, resists flame and low temperature, and bends with a small radius. It is a direct replacement for old rope-type chains that knock and shake.
Industry references place it at medium and high speed, about 1.75 m/s and above, with published ranges up to 3 to 3.5 m/s and wider references to 4 to 6 m/s. The final fit is confirmed against the actual travel profile at enquiry.
The reference range runs from about 1.12 kg/m up to 5.68 kg/m across the nine published size classes, with a tolerance of +/- 0.2 kg/m.
No. The solid PVC body has no lubrication points and requires no oil or grease in normal service, which removes a maintenance task from the lift program.
Common references state about -20 C to +60 C, and some published ranges state -15 C to +60 C. The exact grade is selected for the project climate at enquiry.
Yes. The PVC body is compounded with flame retardant properties, which is a practical safety point for a hoistway environment.
The reference table lists breaking loads from 11.25 kN up to 62.6 kN depending on the weight class. The exact value for your selected size is confirmed at enquiry.
MOQ is one coil per specification, and pre-cut sets per lift project are accepted. Lead time is confirmed at order.
Yes. Guidance covers relaxing the coil, clearing spiral and twist, static hanging for about 24 hours, aligning the guide device with the suspension point, and checking again after a few days of running.
