Product Introduction

If you are outfitting a hospital records room or a law firm archive, this W-072 manual mobile shelving unit is designed to cut your floor space in half. The racks run on floor tracks with a side-mounted hand-crank wheel. Because you only need to open one aisle at a time, this doubles your storage capacity compared to standard static cabinets. It's flat-packed, meaning a 20GP container holds 80 units, and a 40HQ loads 200 units.

Product Feature and Application

The cabinet uses thickened cold-rolled steel, and the standard shelf height is 2400mm. We use a side hand-crank instead of a front crank, because the operating aisles in most archives are very narrow; a front crank would hit the opposite rack.

The doors have independent locks to keep out dust and unauthorized staff. Let's talk about room layout. The standard group distance is 900mm. When you measure your room, use this formula: Length = (Number of Groups × 900) + 50mm + 100mm. The extra 50mm is for the end panel, and the 100mm is the track clearance. If you calculate this wrong, the racks won't fit, so our engineers always draw the CAD layout before production.

Production Details

Here is a real headache in manufacturing tall racks like this: welding the 2400mm uprights. The heat from welding easily warps the steel. If the uprights are crooked by even 2mm, the hand crank will feel extremely stiff. Our production manager, Mr. Li, uses automated welding jigs to keep the frames perfectly square.

Also, hospitals and archives get very humid. We apply an advanced electrostatic powder coating over a phosphated wash. Some factories skip the phosphating to save a few bucks, but we don't, because skipping it means the paint will peel off within two years in a damp basement.

Product Qualification

Our factory is ISO 9001 certified. We don't just test empty racks. We fill the shelves with heavy paper boxes and crank the racks back and forth 500 times to check the track wheels for wear. The powder coating undergoes a 48-hour salt spray test for rust resistance. For sea freight, we do drop tests on the flat-packed cartons because we know port handling is rough.

Deliver, Shipping and Serving

Shipping assembled racks is a waste of money. We flat-pack everything (knocked-down), and the cartons are strong enough to survive ocean transit.

Practical tip for your local installation team: always add a 2% spare parts kit (crank handles, track wheels, and lock cores) to your container order. If an installer accidentally breaks a wheel or a local client loses a key, you don't want to pay $60 in DHL express fees just to send a $5 part from Luoyang to your warehouse. Also, I strongly advise your installers to use a laser level before drilling the tracks into the concrete-if the floor is slanted, the hand crank will jam.

FAQ

Q: Can we customize the size for a specific room?
A: Yes. Send us the room's length and width. We will calculate the exact number of groups and track lengths based on the 900mm group distance.
Q: How many units can fit in a container?
A: A 20GP container holds about 80 units, and a 40HQ holds 200 units, depending on the customized panel thickness.
Q: Is the hand-crank removable?
A: Yes, it's detachable. You pull it out after use so unauthorized people can't move the racks.

Latest News

Our metalworking workshop recently upgraded the CNC stamping die for the shelf panels. This reduced the bending error from 2mm to 1mm, which means the shelf clips now snap into the uprights much easier during installation. It's saving our clients about 10% in local assembly time.
