pulley

3, wear-resistant composite copper sets of round-core: the 21st century and updating new products, has good wear resistance, high load Dutch, and the friction coefficient small, from the applicable burden

2, needle roller bearings round Core: rotational flexibility, compression durable.

3, pulley - sets: 1,metallurgical oily iron core sets of round: low cost, widely applicable small tonnage, the slow speed Pulley.

Hot-rolled steel wheels: light weight, high hardness, apply large pulley manufacturers.

Cast steel pulley: high strength and toughness, but the rope wear larger, only to use the loading large equipment.

2, the pulley: cast iron pulley: lower hardness, the use of the wire rope when injury.

1, hook: The national standards of safety hook, by forging quality steel. Rally coefficient is three times the coefficient.
