Electric Compactor Shelving — System 02 | SHENGMEI

System 02 · Electric drive

Press once. The aisle answers.

Powered carriages on a shared rail spine, controlled per run or from a single panel. Specified where a room is opened dozens of times a day and where staff should never be the ones supplying the force.

What three seconds a trip actually adds up to.

A manual run takes about eight seconds of cranking to open a working aisle. An electric run takes three. On its own that is nothing — across a busy records room it is the difference between a queue and no queue.

Measured on a 6-bay run at 480 kg per bay, operator standing at the panel.

Sixty retrievals a day at five seconds saved each is about 30 working hours a year returned to the records team — before counting the reduction in strain complaints.

Four layers before anything can move.

Electric does not mean uncontrolled. Every carriage carries its own sensing and stop logic, and the run can be worked by hand if the power is ever off.

LAYER 01

Infrared aisle curtain

A beam across the opening stops and locks the carriage the moment anything enters the aisle.

LAYER 02

Pressure edge strip

A mechanical contact edge along the carriage face reverses direction on touch, independent of the sensors.

LAYER 03

Interlocked aisle lighting

Lights come on with the aisle, so an open aisle is a visible one from the far end of the room.

LAYER 04

Hand-crank fallback

Every electric carriage keeps a manual release, so a power cut never seals a room shut.

Featured installation

Provincial land archive

Forty-two electric bays across four runs, replacing static shelving that had reached the walls. The room kept its original footprint and roughly doubled its capacity.

Already got manual runs? Keep them.

Most electric conversions do not start from nothing. The rail, the carriages and the shelving are usually sound — it is the drive that is missing.

1

Survey the existing run

We check rail condition, carriage alignment and floor loading, and confirm which bays can carry a drive unit.

1 day on site

2

Fit drives and controls

Drive units, wiring trunking and control panels are fitted to the existing carriages. Shelving and contents stay in place.

No decanting

3

Commission and hand over

Safety layers are tested in sequence, staff are trained on the panel, and the manual fallback is demonstrated.

Half day

Tell us the room and the retrieval rate. We will tell you if electric pays for itself.

If your team opens aisles fewer than ten times a day, we will likely recommend manual instead. That is not a sales tactic — it is what keeps the tender defensible.
