Auger drives

The auger drive includes the centre auger bearing box, in which the drive chain and the drive sprocket are installed, as well as the auger shafts and auger blades, which are located to the left and right of the centre auger bearing box.

The auger drive is hydraulically powered. The hydraulic motors are mounted on the gearbox, which in turn drives the auger shaft via the drive chain. The mix coming through the conveyor tunnel is evenly distributed in front of the screed by the spreading auger.

Drive chain condition:

Checking the chain

• Check the chain links
• Re-tension the chain if necessary
• If it can’t be tensioned any more: Replace the chain and the drive sprocket

Check the drive sprocket

• Condition of teeth: sharp, broken tips or missing
• Check the sprocket for damage, e.g. such as cracks on the flanks

Elongation of the drive chain

Elongation of the drive chain can be identified by checking how far the setting screws are screwed in.

• TOP: new drive chain
• BOTTOM: worn drive chain
• Chain links are elongated, causing lengthwise stretching of the chain
• No longer any positive connection between the chain and the drive sprocket

Lateral chain play

Chain play can only be determined after removing the chain

• TOP: new, intact drive chain
• BOTTOM: worn drive chain
• Individual chain links are worn
• Increased lateral play in the direction of the chain flanks
• The chain no longer possesses the necessary stability
