base plate, handrail, and toeboard. A ladder has an opening.
* A deviation fast-line sheave.
* The sheave cluster is titled to counteract traveling block's torque. The side plate assembly is faced with derrick man for ease of picking off &
suspending elevators.
* The sheave grooves are intermediate frequency quenched so as to improve surface hardness and extend service life of sheaves.
* All sheaves have double-row conical roller bearings and each bearing has individual lubricating channel.
* The rope guard prevents the wire rope from running out of the sheave grooves.
* Equipped with wooden bumper blocks and retainer net.
* Equipped with a gain hole for use in repairing the sheaves cluster.
