Auxiliary Shoveling Plate Cylinder (Heavy-Duty)

Bore: Φ180 mm

Rod: Φ110 mm

Stroke: 115 mm (short stroke for plate pressing/scraping)

Operating pressure: continuous 35 MPa, max 40 MPa

Max push force: 1,017 kN (at 40 MPa, full-bore side)

Max pull force: 637 kN (at 40 MPa, annular side)

Breakaway pressure: ≤0.5 MPa

Piston velocity: <0.5 m/s

Operating frequency: high-frequency intermittent, dozens to hundreds of scraping cycles per advance cycle

Internal leakage: ≤0.03 ml/min (at 35 MPa, over full service life)

Temperature range: -20 ℃ to +80 ℃ (standard); -40 ℃ to +120 ℃ customizable

Suitable for: steep incline hard rock excavators, incline shaft excavators, rock drift excavators, etc.

Ultra-High-Pressure Heavy Scraping Force

The 1,017 kN thrust effortlessly handles forceful scraping and gathering on hard rock floors. The barrel and rod are forged from high-yield quenched and tempered steel for extreme fatigue life.

High Side-Load Resistance & Guidance

A wide bronze composite guide ring embedded in the bore, combined with an optimized rod-to-bore ratio, effectively absorbs lateral forces during eccentric scraping, preventing rod scoring.

Multi-Stage Seals & Dust Protection

Multiple heavy-duty wipers and a metal scraper ring at the gland completely block rock dust and water. The main seal is a hydrolysis-resistant polyurethane/filled PTFE composite, guaranteeing zero external leakage.

Cushioning & Safety Holding

Progressive cushions at both ends eliminate end-stroke impacts. Optional hydraulic locks securely hold the plate position.

Optional Smart Monitoring

A built-in magnetostrictive displacement sensor provides real-time plate position feedback, supporting automated loading control via the machine’s electronic system.

Special high/low temperature seals

Full stainless steel body and piston rod

Integrated displacement sensor

Explosion-proof / mining certifications

Special mounting distances and port configurations
