PRODUCT CONTENTS
Hydraulic Belt Winder
The JY Series hydraulic belt winder uses a hydraulic motor to clamp, pull and wind conveyor belts, fully mechanizing belt recovery. Traditional manual recovery — cutting, pulling out, folding and carrying the belt — is labor-intensive, slow and hazardous. The JY winder automatically completes clamping, pulling, cutting, winding into a coil and 360° rotating discharge. Designed for underground extendable belt conveyors, it is also used in ports, power plants, cement plants and steel mills.

Contact-Type Wedge Backstop
Backstops prevent reverse runaway of loaded inclined belt conveyors when the drive stops suddenly. The NJZ/NJ wedge-type backstop mounts directly on the reducer output shaft or drive pulley shaft. Precision heat-treated alloy-steel wedges provide accurate engagement, high load capacity and easy release — with the drive system remaining fully unloaded during the locked state, allowing safe maintenance.

Key Features
Non-Contact Backstop
NF non-contact backstops use special wedge geometry and centrifugal force so that rotating and stationary elements have no physical contact during forward operation — zero wear, zero drag and long service life — while still engaging reliably in reverse. CKF-A is designed for high-speed anti-reverse duty and can also serve as a dual-drive overrunning clutch. Available in N and S rotation directions.

Belt Correction (Anti-Misalignment) Devices
Belt misalignment directly affects conveyor operation and belt life. Gaosheng Huayu offers four complementary correction technologies for all conveyor types in mining, power, metallurgy and chemical industries.
WD Passive Electric Corrector
No external power required — belt contact drives low-speed DC generators that rotate the correction idler, returning the belt to center. Fast response, unaffected by temperature, low cost, patented.
ZJPS Four-Bar Linkage Corrector
Four-bar linkage design ideal for mine flame-resistant solid-woven belts and belts over 500 m. Precision, long service life, site-adjustable detector wheels, maintenance-free, no power/water/oil required.
| Belt Width | 800 / 1000 / 1400 / 1600 mm |
|---|---|
| Belt Speed | < 6 m/s |
| Max Misalignment | ±50 mm |
JPT Automatic Correction Roller Unit
PLC-based intelligent real-time correction; correction force many times greater than conventional units thanks to special mounting and roller technology. Suitable for high/low temperature, humid and dusty environments; can replace additional bend pulleys to save cost.
| Belt Width / Speed | 500 ~ 2,400 mm / 0.5 ~ 5.0 m/s |
|---|---|
| Ambient Temp. | -28°C ~ +52°C |
WY Passive Hydraulic Corrector
Belt contact drives a low-speed pump whose oil actuates a cylinder to tilt the self-aligning idler, generating corrective force — then stops automatically after realignment. One WY unit equals 5+ mechanical correction rollers; best solution for reversible belts.
| Standard Range | Belt width ≤2,400 mm, speed 0.8~4.5 m/s (custom beyond) |

Impact Bed
The impact bed is installed under the transfer point to support and protect the belt, effectively absorbing the impact of falling material and preventing belt damage and misalignment. Slide bars combine flame-retardant, anti-static UHMWPE nano-material with buffer rubber on a metal frame; a patented dual-stage shock-absorbing system handles large lump coal or rock.
