Electric Retractable Bleachers & Telescopic Grandstands

Motorized telescopic seating that folds into a compact wall stack and opens into tiered grandstands — one hall, two usable spaces. Made in Foshan, China since 2008, with three series to match different budgets and ceiling heights.

Three series, one purpose

Pick by ceiling height and by how the room is used — not by price alone. The same electric drive platform sits under all three.

How a telescopic bleacher works

Each row sits on a steel understructure carried by cast travel wheels. When the motor runs, a drive shaft turns worm gearboxes on every row and the whole bank expands or retracts in parallel — guided at both the top and bottom so rows never skew or jam. Row locks engage automatically as each tier seats into place, and the system stops at its mechanical and electronic limits.

• Deck: ≥18 mm anti-slip plywood with fire-rated edge sealing; aluminium nosing strip on the front edge.
• Guardrails: automatic nesting type, over 1,100 mm high, gaps under 100 mm, maintenance-free.
• Wheels: φ≥100 mm dual-hardness rubber, five per column — works on timber and concrete floors.
• Safety chain: emergency stop button, travel warning bell, auto stop at both extremes, no live current when parked.

Frequently asked questions

How much floor space does a retractable bleacher need?

The retracted stack is roughly one metre deep per bank plus the aisle, so a 10-row bank typically stores in about 1.2–1.5 m against the wall. Send us your room dimensions and we will confirm the footprint and seat count.

What ceiling height do I need?

The Shenshi series starts at 130 mm per row, which suits rooms with limited headroom. As a rule, allow 300–350 mm per row plus 200 mm clearance for the top row — we verify this against your drawings before quoting.

What is the minimum order and lead time?

MOQ is 40 seats. Standard production takes 30–45 days after drawing approval; fully customised projects take 45–60 days.

Can it be installed on an existing floor?

Yes. The travel wheels are dual-hardness rubber and work on both timber sports floors and concrete. Fixing is by through-bolts — no welding is required on site.

What happens if something fails?

Electrical components carry a 1-year warranty and the structure 3 years. We keep spare motors, control boards and cast wheels in stock and ship them by air within days; our team supports installation by video call.
