Synchronous Operation with Battery Powered Machine Skates
In a typical multi-skate train, the battery powered machine skate handles drive and steering while two W6SP/W8SP auxiliary wheels follow behind. When the train is configured for synchronous operation, the powered skate and the auxiliary wheels stay phase-locked — the load travels as a single rigid unit, no twisting, no manual alignment needed. This is the standard “remote control electric machine skates with lift function” workflow used in shipbuilding, aerospace and energy projects.
How to Choose W6SP vs W8SP
- W6SP (6 wheels) — paired with MH20 / MH25/MH30 powered machine skates (20–30 ton traction). Use for medium-weight loads and short-to-medium travel.
- W8SP (8 wheels) — paired with MH35/MH40 / MH50 powered machine skates (35–50 ton traction). Use for heavy loads and long travel distances.
Frequently Asked Questions
Q: Can two battery-powered machine skates work together with the auxiliary wheels?
A: Yes. Two or more battery powered machine skates can run in synchronous operation; pair with W6SP/W8SP auxiliary wheels for the classic 3-skate or 4-skate train.
Q: How much weight can the W6SP / W8SP support?
A: The W6SP and W8SP are passive casters — they do not provide traction on their own, but they share the load with the powered skate. Combined with an MH50L (Lift series) or MH50P (Professional series), the train can move 50+ tons.
