Manual Operation

Hand-wheel power.
Zero electricity.

The same high-density capacity as powered systems, moved by a precision gear drive: one pound of effort on the handle moves up to 10,000 lb of loaded carriage. No wiring, no controllers, no service contract.

Manual compactor shelving run with five-spoke hand wheels and numbered bays in a records corridor
Shengmei manual compactor · hand-wheel drive
1 lb → 10,000 lbOne pound of force on the handle moves up to 10,000 lb of loaded carriage — the benchmark mechanical-assist systems are judged by.
0 W POWERNo wiring, no circuits, no controllers. Installs in any room a floor can carry — including basements and heritage buildings.
50% FLOOR BACKFixed aisles collapse into one moving aisle: the same collection in half the floor, or double the collection in the same floor.

Mechanical Safety

Locked, braked and tip-proof — by hardware, not sensors.

A hand-wheel run protects people and collections with physical mechanisms that never need power, firmware or calibration.

Aisle-lock knob

The lock above the handle fixes both neighbouring carriages, so the open aisle cannot drift closed while staff are working in it.

Anti-tip hooks

Every carriage hooks into the rail line, holding the run upright under uneven loading — and meeting seismic requirements where specified.

Braked parking

Wheels brake the instant the handle is released, and a positioning stop keeps parked rows from creeping on floors that deflect.

Keyed hub lock

A lock in the handle hub freezes the drive shaft, so only authorised staff can move the run or open its aisles.

Closing bumpers

Rubber bumpers absorb the impact when carriages close, protecting the structure, the shelves and the files inside.

Dust & light seals

Magnetic strips and rubber seals close the gaps between columns, shutting out dust, light and pests whenever the run is parked.

Engineered Structure

The quiet engineering under every run.

What makes a hand-wheel run feel effortless at year fifteen was decided at the welding table.

01 · CARRIAGEWelded uniframe base

One welded frame instead of bolted sections — the carriage stays square under tonnes of load instead of racking out of alignment.

02 · CHASSISReinforced steel members

A 3.0 mm cold-rolled chassis carries shelf load straight down to the wheels; uprights stay true through decades of daily use.

03 · TRACKSub-millimetre rails

Rails are levelled to sub-millimetre tolerance and paired with a continuous drive shaft, so both sides of the run move in perfect sync.

04 · FLOORFlush, finishable track

Low-profile rails sit flush with the finished floor and accept ramps and deck covers in any flooring — accessible, with nothing to trip on.

Plan Before You Order

Four checks that decide the project.

A mobile run concentrates more weight on its rail lines than almost anything else a building holds — 125–200 psf for paper and books, far above the 50 psf office norm. Checking these before the quote prevents the surprises that surface after delivery.

Send us the room dimensions and collection type — we return rail positions, bay count and a floor-load summary with every quotation.
1
Floor load rating

Paper and books need 125–200 psf (≈6–10 kPa) across the system footprint; museum-grade storage 275–300 psf. An office-rated floor (50 psf) is not enough.

2
Floor levelness

Within ±3 mm over any 3 m span. Out of tolerance is still workable — rails are shimmed level during installation, adding about half a day.

3
Slab & floor covering

150 mm slab on grade, or 200 mm on upper floors. Carpet is cut back along the rail lines; vinyl and epoxy can stay.

4
Working capacity

Plan the layout to about 85% full and keep expansion bays in the design — a run filled to 100% on day one has nowhere to grow.

FAQ

Questions buyers actually ask.

Does a manual system need any electricity?
None at all. The drive is a hand wheel, a gearbox and a chain. That makes it a fail-safe choice for basements, heritage buildings and archive rooms without spare circuits — and it removes every electronic failure point from the system.
Can it be installed on an upper floor?
Often, yes — after a structural engineer confirms the slab can carry the concentrated load (typically 125–200 psf) along the rail lines. Ground-floor slabs on grade are the easy case; suspended floors may need a lighter tier configuration or local reinforcement.
How much weight can one person actually move?
With the 30:1 reduction gearbox, roughly one kilogram of effort at the handle moves a tonne of loaded carriage. A fully loaded run of up to 10,000 lb opens with a light, continuous turn — no strength required.
What maintenance does it need?
Lubricate the chain and check rail alignment once a year — about 30 minutes per carriage with standard tools. There are no firmware updates, no calibration and no control boards to fail.
Can we expand or relocate the system later?
Yes. Runs are modular: add bays, extend a carriage, or unbolt the whole system and re-lay the rails in a new room. The steel outlives the layout.
