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.

DESIGN ADVANTAGES

Balanced Dual-Jaw Clamping Geometry

Centerline closing balances load forces without side wall friction.

01

Symmetrical Center Cutoff

Dual synchronized jaws close toward the centerline, eliminating off-axis torque on chute side-walls.

02

High Lump Crushing Capability

Enormous hydraulic closing force shears or displaces large trapped rocks, ensuring complete closure.

03

Precision Synchronized Linkage

Heavy mechanical tie-rod synchronizer ensures perfectly matched jaw movement even under uneven rock loading.

04

Low Maintenance Pin Bushings

Self-lubricating composite bronze bushings with high-pressure grease channels ensure years of maintenance-free rotation.

APPLICATIONS

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.
