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.

Pulley structure and materials

Lifting pulley is an important tool hoisting, it is simple, easy to use, can be repeatedly changed pulley traction cables
