Self-Controlled Hydraulic Belt Tensioning Device
HSX DYL Series self-controlled hydraulic belt tensioners maintain stable, mathematically controlled take-up tension across heavy conveyor belts under changing startup, running, and heavy-surge load conditions. By eliminating belt sag and drive pulley slippage, the DYL system protects long-distance conveyor belting from fatigue breakdown and catastrophic tears.
Model Series & Engineering Parameters 6 Standard Tension Classes

Engineered for Zero Belt Slip and Surge Absorption
Automatically increases tension by 1.3-1.5x during motor acceleration, then smoothly ramps back to nominal running tension.
Intelligent Multi-Stage Tension Control
Automatically switches between startup tensioning, steady-state cruise tensioning, and emergency brake tensioning via digital PLC.
High-Response Hydraulic Accumulator Banks
Bladder accumulator bank instantly dampens transient shock waves when heavy shock loads drop onto the conveyor belt.
Dynamic Cable Winch & Cylinder Synergy
Combines large hydraulic take-up travel with hydraulic cylinder precision, accommodating thermal expansion and belt stretch.
Fail-Safe Mechanical Locking Dog
High-reliability mechanical lock holds the carriage securely in place during hydraulic maintenance or plant shutdown.
Proven in Severe Plant Environments
Delivering high thrust and zero-drift actuation across critical heavy industrial facilities.
Deep Shaft Mine Inclined Belts
Prevents belt roll-back and slip across steep high-tonnage mining conveyor declines and inclines.
Multi-Kilometer Overland Conveyors
Absorbs complex longitudinal wave oscillations during long-distance conveyor startup and stopping.
Coal Fired Power Plant Feeders
Maintains unyielding tension for main boiler feeding trunk lines under 24/7 continuous duty.
High-Throughput Port Shiploaders
Eliminates take-up tower counterweight jams, saving valuable jetty and dock top structure.
