A chain of small buckets on a wheel — the oldest water lift there is.
| Group | Lifting & Pumping |
|---|---|
| Standard size | 1000 × 800 × 2100 mm |
| Water | Recirculated from the basin; the element drains back by gravity |
| Power | 220–240 V, single phase — pump duty set by the zone loop |
| Materials | SUS304 frame · HDPE touch surfaces · cast acrylic windows |
| Supply | Single unit or batch · OEM to your drawing |
| Lead time | Standard 4–8 weeks after deposit (confirmed per contract) |
| Warranty | 1 year, structure and control |
| Documents | Specification sheet · control diagram · spare-part list |
A standard element: the geometry and the finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and the way it mounts to the basin can be adapted without a new design cycle.
A vertical loop of chain carrying open buckets. Visitors turn a handwheel; the buckets dip into the basin, rise full, tip at the top and empty into a channel.
Chain drive rather than belt, so there is no slip and the buckets keep station. Each bucket is carried mouth-forward, which is what makes it empty cleanly at the top instead of pouring back down the run.
Turn the wheel and count the buckets as they come up. Two children on the wheel will out-run one, which is usually the first thing they discover.
Free-standing on the apron against a wall or a screen. The chain run is enclosed on the back and sides; only the bucket path is open to touch.
Other elements from the same group. All held to the same specification, the same material palette and the same control package.

An open helical screw that lifts water two metres by hand.

A large spoked wheel with bamboo-section scoops, fed by a hand pump.

Fills until it is top-heavy, then dumps itself. Nobody has to explain it.

A model dam with working gates — hold the water back, then let it go.
