瑞士采购需求：叉车、铲车、熨斗、叉车、升降车、蒸汽熨斗

I'm looking for an industrial overlock machine featuring a 4-thread stitch. The throat space should exceed 120 mm, and I require automatic thread trimming with a direct-drive servo motor. The machine needs to handle cotton, jersey, and polyester blends efficiently. We plan to purchase thousands of units annually after successful development, so reliability for continuous operation is essential. The machine should operate at a minimum speed of 5000 stitches per minute. Please provide detailed specifications and pricing at your earliest convenience.
