The swing device pairs a hydraulic motor with a planetary reduction gearbox. We supply complete swing devices plus every internal part — so you can replace the whole unit or repair just what is worn.

Don't see your model? Send us the nameplate photo — we cover 15+ brands from 1 to 60 tons.
If the housing and gears are healthy, a seal kit plus motor internals costs far less. If the planetary gears or housing are damaged, a complete swing device is usually faster and safer. Send us a video of the symptoms and we will advise honestly.
Every swing device is run-out and pressure tested before packing; we can share a test video with your order number.
Yes — that is exactly what one-stop supply means. Pumps, valves, hoses, seal kits and GET can share one container and one invoice.
Send your part number, machine model or a photo of the nameplate — WhatsApp is fastest.
