2g/m3 CITIC HIC Machine Parts Mine Hoist Plastic Lining Plates High Mechanical Strength
Mine hoist plastic lining plates high mechanical strength long service life
PLASTIC LINER FOR HOIST
1,The mechanical strength is high, and the service life is long.
The compressible strength is 7~10 times higher than that of the wood lining, no crushed, and rope groove rubbed phenomena etc. The service life is 5 times higher than that of the wood liner.
2, Wide range of application
Sun-crack and moisture resistance, no Sun-crack or decay of wood liner,especially suitable for mine drench water and corrosion resistance and being used in high corrosive harsh environment and down-hole conditions.
3,The proportion is light, and no water absorption
The proportion is 0.98, which is lighter than the wood lining after water absorption.So it will not increase the reactive power and rotational inertia of the equipment.
4,Compression molding, smooth rope groove surface
The installation is convenient. The wire rope are arranged in alignment. And the phenomena of rope skipping or bitten rope will not occur, which greatly extends the service life of the steel wire rope.
