Product Classification
- By installation type: Weld-on pick holders (permanently welded on mining machinery cutting drums/arms, high stability) and bolt-on pick holders (detachable, easy to replace and maintain).
- By application: Shearer-specific pick holders (adapted to coal cutting drums), roadheader pick holders (for tunnel excavation and coal cutting), and continuous miner pick holders (for high-efficiency continuous mining).
Key Specifications & Parameters
| Material | 42CrMo alloy steel, 35CrNiMo alloy steel (forged + heat treatment, ensuring high strength and toughness). |
| Hardness | HRC 38-45 (body), HRC 55-60 (inner hole and contact surface, enhanced wear resistance). |
| Inner hole diameter | 19mm, 22mm, 25mm (matching common coal mining pick shank sizes). |
| Length | 50-150mm (varies by mining machinery model and cutting requirements). |
| Bearing capacity | ≥2500 N/mm² (impact resistance, adapting to high-load coal cutting). |
| Connection method | Welding, bolt fixing, or lock pin fixing (depending on classification). |
| Applicable picks |
U92, U82, U76, U62 series coal mining picks (mainstream models in coal mining). |
Product Features & Advantages
- High impact toughness: Forged alloy steel and quenching-tempering heat treatment ensure the holder can withstand high-frequency impact during coal cutting, avoiding deformation or fracture.
- Superior wear resistance: Surface hardening treatment on contact surfaces reduces wear caused by pick rotation and coal/rock friction, extending service life.
- Secure fixing: Precision-machined inner hole ensures tight fit with pick shank, preventing pick loosening or falling off during high-speed operation.
- Easy installation & maintenance: Bolt-on type allows quick replacement; weld-on type ensures stable connection, reducing downtime.
- Strong compatibility: Matches mainstream coal mining picks and mining machinery with strong versatility.
- Corrosion resistance: Surface anti-rust and anti-corrosion treatment adapts to humid and dusty coal mining environments.
Application Scenarios
- Underground coal mining: Coal cutting and loading operations with shearers and continuous miners in underground coal seams.
- Coal seam excavation: Tunnel excavation and coal seam cutting with roadheaders in coal mines.
- Coal processing: Coal crushing and sorting equipment in coal preparation plants, fixing cutting picks for crushing operations.
- Mining auxiliary operations: Cutting and cleaning of coal waste and rock in coal mine roadways, ensuring smooth operation of mining equipment.
