Comparison of electric chain hoist and wire rope electric hoist
Comparison between ELK electric chain hoist (hereinafter referred to as electric chain hoist) and wire rope electric hoist (hereinafter referred to as wire rope hoist) :
1, use
ELK chain electric hoist, quite slow speed, suitable for precise positioning of the assembly, precision processing, mold replacement of domestic wire rope electric hoist, slightly faster speed, suitable for large tonnage of simple lifting, lifting.
2,
ELK chain hoist: small size, chain wheel and chain closely together, the center will not deviate, easy to locate domestic wire rope hoist, for the winch structure, large size, the greater the lift, the longer the drum, lifting hook is easy to deviate, not easy to locate
3. Brake device
ELK electric chain hoist: side magnetic brake system, which can brake at the same time when the power is cut off, to ensure the absolute safety of braking when lifting. Domestic wire rope hoist, brake pads belong to vulnerable parts, often check brake wear. Wear not timely replacement, easy to slip
4. Check and replace
ELK chain hoist, can be visual and vernier caliper chain abrasion and extension, easy to check domestic wire rope hoist, at least 2 strands of more than the wire rope composition, broken wire inside is not easy to check, easy to bend deformation
5. Safety factor
ELK chain hoist: safety factor of ELK experiment is 6 times, tension of more than 1000N/mm2 domestic wire rope hoist: domestic wire rope reference is 5 times safety factor.
