Why Tensioning Matters

Correct Tension = Belt Life, Safety and Availability

A take-up system keeps the belt under the right tension across all operating conditions — preventing slip, stretch, mistracking and structural damage. Choosing the right one is an engineering decision. Here is the range we manufacture.

PLC Constant-Tension

ZYJ Series

160–700 kN, PLC-controlled constant-tension for long-distance conveyors. Water-glycol flame-retardant hydraulic medium.

Compact Hybrid

ZY / DYL Series

50–400 kN hydraulic-mechanical tensioner — compact footprint for space-constrained installations.

Extreme Cold

ZJ Series

Patented electric-winch tensioner for extreme cold regions — 50–200+ kN, up to 35 m stroke, no hydraulic fluid to freeze.

Dual-Purpose

JZB Series

Hydraulic tension winch for belt tensioning and general winching duties — 40–79 kN, 380/660/1140 V.

Two-in-One

HYZJ Series

Integrated tensioner-winder combining tensioning and belt recovery in one unit — 320–600 kN.

Smart / VFD

ZPJ Series

VFD smart tensioning for intelligent mines — 50–120 kN rated tension, gas-mine rated, remote monitoring.

Max Tension Force	160 / 200 / 250 / 300 / 400 / 500 / 600 / 700 kN
Max Stroke	0 – 20 m
System Pressure	16 MPa
Power / Voltage	15 kW / 380 · 660 · 1140 V
Hydraulic Medium	Water-glycol or emulsion (flame-retardant)
