Raise Climbers (Alamak)
Alimak Company introduced this technique in 1957, and even today it is often used in driving blind raises which have long lengths. The Alimak raise climber is designed to drive raises up to 100 m long, or more. There are several kinds of climbers available: pneumatic, electric and diesel (hydraulic driven).The following are important features of this technique:
- It makes it possible to drive very long raises, vertical or inclined, straight or curved and mostly rectangular shape.
- The raise climber can be driven into a safe position using backward guardrails.
- Because of its features for blowing air and water at the face after blasting, risks of foul gases are eliminated, and the time required for ventilation is reduced.
- An additional extension piece can be connected to the platform
