The product covered here is a dragging device which is installed in the derrick, and support the mine hoist, hoist support drag between the rolls to enhance the container, and guide the use of wire rope steering. Rope groove is with plastic lining or plastic block, which will increase the service life of wire rope.
This material is the casting steel G42CrMo4 ISO14737:2003(E), which is a fully killed steel, vacuum-degassed and processed to a fine grain size structure with improved properties both in toughness and in elongation.
Chemical composition: (%)
Checked at room temperature in the delivery condition i.e. after completion of the quality heat treatment from cylindrical cast-on test blocks (? 60 mm x 250 mm) available on every Sheaves: both the sample preparation and the testing comply with ASTM A 370-96.

Delivery condition: Hardening and tempering.
All operations are carried-out at the in-house foundry plant.
The castings are manufactured in a workman-like manner as required in the German standard DIN EN
1599-1: August 1997, ruling the delivery conditions of castings. The molding is individually carried out within a modular flask by using a sand preparation based on resin bonding.
The melting is carried out in the oxygen steel plant ( 2 off 180 t BOF converters ); the ladle capacity allows a continuous bottom pouring process the speed of which is permanently controlled. The metal analysis is checked by using a computer linked spectrograph.
Every sheave undergoes a combined quality heat treatment (Hardening and tempering) aiming both to grain refining and to stress relieving.
In order to meet the inside quality free of defect, we rough machine each sheave foe inner NDT control.
UT: ASTM A609 Level II for the groove and boss center.
MT: 100% ASTM A125 level I
Fine machine every sheave totally according to drawings.
Fettling and dressing
The castings are coated by antirust oil FPC-600 for transportation.
Every sheave is packed well and ready for delivery.
The fabrication route is governed by the provisions of the implemented Quality System ISO 9001: 2000.
The standard documentation ensures the full traceability of every process step:
1. Manufacturer test certificates according to DIN EN 10.204 § 3.1 including chemical composition, mechanical properties and non-destructive examination;
2. Dimensional check supported with a "as-built" sketch;
3. Record of the quality heat treatment
