Abstract

A portable raise climbing system is provided that comprises a starter box for interfacing with an existing raise climb track, a raise climber that is deployed by the system onto the existing track for normal raise excavation operations, and a transporter. The transporter is configured to carry the raise climber from site to site by interfacing with moving equipment. The moving equipment preferably includes a front hydraulic quick connect/disconnect lift system, e.g. front-end loader, forklift, plough, scooptram, etc.

Claims (10)

1. A method of enabling a raise climber to be useable in a plurality of raises in a mine, the method comprising:

for each of a plurality of said raises, attaching a respective one of a plurality of starter blocks to an existing rail used in a corresponding one of said plurality of raises, each of said starter blocks comprising a respective first body with a first rail configured to align with said existing rail used in a respective raise, a first interface for mating with the existing rail used in the respective raise to facilitate movement of said raise climber from said starter block onto said existing rail, and a second interface for mating with a transporter carrying said raise climber to facilitate movement of said raise climber from said transporter to said starter block;

supporting said transporter on a transport vehicle, said transporter comprising a second body with a second rail configured to carry said raise climber and to align with each of the first rails on the plurality of starter blocks, and a third interface for mating with each of said second interfaces on said plurality of starter blocks to align said first and second rails for permitting movement of said raise climber from said transporter onto any one of said starter blocks;

supporting said raise climber on said transporter;

deploying said raise climber onto one of said starter blocks to permit said raise climber to be used in the corresponding one of said plurality of raises;

enabling said raise climber to return to said transporter;

moving said transporter to another one of said starter blocks; and

deploying said raise climber onto another one of said starter blocks to permit said raise climber to be used in another one of said plurality of raises.

2. The method according to claim 1 , wherein enabling said raise climber to return to said transporter comprises interfacing said second body with a corresponding first body on said one of said starter blocks.

3. The method according to claim 1 , further comprising moving said transporter away from said one of said starter blocks subsequent to deploying said raise climber onto said one of said starter blocks.
