Fault Phenomenon: Vogele 1800-3 paver under full load, the middle conveyor belt slips, material supply interrupted.

Troubleshooting Process:
– Checked tension: insufficient conveyor belt tension cylinder pressure.
– Checked drum: drive drum surface worn smooth.
– Checked belt: inner side of belt contaminated with oil.
– Checked load: excessive material exceeding design capacity.

Root Cause: The conveyor belt tension cylinder is leaking, causing insufficient tension; combined with oil contamination on the drive drum surface, friction is insufficient, leading to slippage.

Required Parts: Repair tension cylinder, clean or re-wrap drive drum.
