Crossframe

• for faces with up to 7° incline

• low dumping height

• less dust

• lowest drive frame configuration

• full loading effect, no lost coal

• combined advance of AFC and BSL

Side discharge

preferred use in incline mining conditions

• for faces over 5° incline

• option for combined or seperate advance of AFC and BSL

• position of BSL close to face exit

• ideal for gates with floor step

Overhead discharge

universal solution for all kind of mining condition

• for discharging big and hard lumps

• option for combined or seperate advance of AFC and BSL

• suitable in changing mining conditions

Taildrive

suitable for all kind of mining conditions

• can be positioned in face or gate

• telescopic drive for chain tensioning by two cylinders

• for faces with all inclines

The Challenge:

The wear in the upper race, called Wash-Out-Effect

The Solution:

By turning the central pan, the almost not worn lower race becomes the new upper race. This achieves a New-Race-Effect.

Progressive Wear Effect

Numbers in general, depending of ash and stone content, etc.

Double Life Pan features:

■ 1x central pan with 2x upper races
■ 1x base frame for minimum 2x central pans with 4x upper races
■ up to 60 mm deck plate
■ deck plate material 400 to 440HB
■ rolled profile up to 400HB
■ rolled profile with straightened molecule structure
in conveying direction

 Cost Advantage

Roller Curve
Conveying around the corner

• rear AFC

• shortwall

• longwall

Short facts

• connection of AFC and BSL to one conveyor

• no friction at inside curve, because a roller disc guides the flight bars around the corner

• usable with single middle chain up to size 56x175

• no special roof support needed at face end

• maintenance-free

• less dust and less fine coal in production, because no transfer point at face end

• good loading and undercut possibility until face end, because shearer does not need to ramp up

• no lost coal because conveyor and Roller Curve stay on the bottom

• face entry is wide open

• increase of safety due to better and easier access of face

• less down time due reduced number of machine components

Shortwall

For pillar extraction up to 100 m

• only one transmission in the gate needed

• no special roof support at face end necessary

• less cables and hoses along the face, only one power cable for shearer necessary

Longwall

For high efficiency up to 350 m

• no transmission at main gate area necessary

• suitable for chain sizes 34, 42, 48 and 56

Rear AFC

For caving methods up to 200 m

• only one transmission in the gate needed

• high security for men and machines, because no transmission in caving area
