Design Features
The side plate assembly is made of thick steel plate.When hoisting or lowering the unloaded elevators,the wire line is always kept taut to facilitate the line spooled on the drum and the empty hook lowered.
The sheave grooves are intermediate frequency quenched so as to improve surface handness and extended the service life.
Equipped with double-row conical roller bearings and each bearing has individual lubricating channel.
Queched & tempered alloy steel shaft with lubrication hole of each bearing.
Heavy duty wire line guard.
The travelling blocks conform to API Spec.8A/8C
