AS 3785.4 – 2002 Underground Mining – Shaft Equipment Part 4: Conveyances for Vertical Shafts
AS 3785.4 – 2002 Underground Mining – Shaft Equipment Part 4: Conveyances for Vertical Shafts specifies requirements for conveyances used in vertical-shaft mine-winding installations, including fixtures on the conveyance, but not suspension pins for connecting head rope, tail rope attachments or gripper assemblies.
This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee ME-018, Mining Equipment, to supersede AS 3785.4—1992.
The objective of this Standard is to provide requirements for the safe design and manufacture of conveyances for vertical mine shafts. This Standard is Part 4 in a series of Standards on shaft equipment for underground mines as follows:
- 3785 Underground mining—Shaft equipment
- 3785.1 Part 1: Drum winding overwind safety catch systems
- 3785.2 Part 2: Friction winding arresting systems
- 3785.3 Part 3: Drum winding gripper systems
- 3785.5 Part 5: Headframes
- 3785.6 Part 6: Guides and rubbing ropes for conveyances
- 3785.7 Part 7: Sheaves
- 3785.8 Part 8: Personnel conveyances in other than vertical shafts
This Standard Covers:
- 1 SCOPE
- 2 REFERENCED DOCUMENTS
- 3 DEFINITIONS
- 4 RATING
- 5 MATERIALS
- 6 STRUCTURAL
