Electro-Hydraulic Clamshell Jaw Gate
HSX Clamshell Jaw Gates utilize dual synchronized opposing arc gates actuated by high-thrust electro-hydraulic cylinders. Designed specifically for severe heavy lump cutoff applications such as run-of-mine ore bins and primary crusher feed chutes where single gates experience severe off-center wedging.

Balanced Dual-Jaw Clamping Geometry
Centerline closing balances load forces without side wall friction.
Symmetrical Center Cutoff
Dual synchronized jaws close toward the centerline, eliminating off-axis torque on chute side-walls.
High Lump Crushing Capability
Enormous hydraulic closing force shears or displaces large trapped rocks, ensuring complete closure.
Precision Synchronized Linkage
Heavy mechanical tie-rod synchronizer ensures perfectly matched jaw movement even under uneven rock loading.
Low Maintenance Pin Bushings
Self-lubricating composite bronze bushings with high-pressure grease channels ensure years of maintenance-free rotation.
Proven in Severe Plant Environments
Delivering high thrust and zero-drift actuation across critical heavy industrial facilities.
Primary Mining Chutes
Underground ore pocket discharge, gyratory crusher feed bins.
Quarry Aggregate Hoppers
Riprap stone loading, ballast gravel batch discharge.
Blast Furnace Stock Houses
Coke breeze bins, iron ore pellet weigh hopper discharge.
Bulk Train Loadout Bins
High-speed automated train car batch loading chutes.
