Case Study

Conveyor Projects & Applications

How our hydraulic take-up systems and conveyor components perform in real installations — long-distance haulage, extreme cold, intelligent mines and belt modernization projects.

Long-Distance Haulage

ZYJ Constant-Tension on a 5 km Underground Mainline

A ZYJ-400/15D PLC-controlled tensioner maintains constant tension on a 5 km mainline belt under variable load — eliminating belt slip and reducing splice failures.

Result: belt stretch automatically compensated; maintenance call-outs cut by more than half.

Extreme Cold

ZJ Winch-Type Tensioner at a High-Latitude Surface Mine

For a surface conveyor operating at -35°C, a ZJ electric-winch tensioner replaced a hydraulic unit that froze every winter — no hydraulic fluid, no cold-start problems.

Result: year-round operation with zero cold-weather tension failures.

Intelligent Mine

ZPJ VFD Smart Tensioning in a Digital Mine System

A ZPJ-540/55 VFD tensioner integrated into an intelligent mine's centralized control — tension monitored and adjusted automatically, with data feeding the mine SCADA.

Result: remote supervision of tensioning from the surface control room.

Belt Replacement

Mechanized Belt Change with JY Winder + WZD Devices

A 1,200 mm conveyor's 1.8 km belt replaced in a planned shutdown using a JY hydraulic belt winder and WZD belt replacing devices — no manual belt handling on site.

Result: belt change completed in days instead of a week, with fewer workers.

Safety Retrofit

Backstop & Brake Retrofit on an Inclined Conveyor

An inclined underground conveyor retrofitted with an NJZ contact backstop and KPZ disc brake system to meet updated anti-runback safety requirements.

Result: fail-safe protection against belt runback on load loss.

National Key Project

500-Ton Hydraulic System for Mine Water-Disaster Prevention

Designed and manufactured entirely by our company for a national key project — a 500-ton hydraulic system (30-ton total weight), the first of its kind in China.

Result: delivered and commissioned on schedule; hydraulic products also used in national aerospace laboratories.
