The Mobile Shelving Installation Process, Step by Step

Mobile shelving from any reputable manufacturer is well engineered. What separates a system that runs sweetly for 25–30 years from one that is stiff, noisy and worn out in eight is almost entirely the installation — specifically, whether the rails were laid dead level, correctly shimmed and properly fixed.

Carriages are unforgiving. A rail run that falls even slightly makes aisles heavy to open, causes carriages to creep unaided, loads the drive gear unevenly and accelerates wheel and bearing wear. None of that is visible on handover day; all of it is expensive later.

The sequence below is how a professional installation runs. It is worth understanding even if you are not doing the work, because it tells you what questions to ask a supplier and what to look for on site.

Nothing can be priced or designed without a survey, and no reputable supplier will quote firm from a phone call. The surveyor measures the room accurately, including height to the lowest obstruction — sprinkler heads, light fittings, ductwork, beams and pipe runs all limit bay height and are routinely missed on drawings.

The survey records what will be stored and how heavy it is, because archive boxes, bound volumes, deeds and laboratory samples all load shelves very differently. It records the required shelf pitch, whether lateral filing, solid or wire shelving is needed, and whether operation should be manual or electric.

It checks the floor: level and flatness along every proposed rail line, construction and finish, movement or expansion joints, underfloor heating or services in the slab, and — critically — floor loading capacity. Mobile shelving roughly doubles the load applied compared with static shelving, so the structural position has to be confirmed before design is fixed. See our floor loading guide.

Finally it records access: door widths, corridor turns, stair and lift dimensions and weight limits, loading bay availability, parking and permit requirements, and any restrictions on working hours in occupied buildings. Access constraints change installation duration more than any other factor.

The survey produces a scaled CAD layout showing rail runs, carriage positions, bay configuration, aisle position and clearances, and end and fascia panel details. Alongside it you should receive a stated capacity in linear metres of shelving, the shelf safe working loads, the applied floor loading position, and a fixed price with exclusions written down.

Review the drawing carefully before signing. Check that aisle width suits the trolleys and equipment you use, that the layout leaves clear egress, that sprinkler and lighting coverage still works with aisles closed, and that fire equipment, radiators, sockets and risers are not obstructed. Check the linear metre figure against your actual requirement plus a realistic growth allowance — the cost of adding capacity now is far lower than adding it later.

Sign-off starts the manufacturing lead time. On UK projects this is typically 4–8 weeks from drawing approval to installation, depending on specification and finish. Powered systems and non-standard colours generally sit at the longer end.

The room must be completely empty on the day the crew arrives. That sounds obvious and it is the single most common cause of delay. If an existing archive has to be decanted, agree who is doing it and where the contents will go, and — where filing order matters — crate and label in sequence against a run-map so material can be reinstated in the same order.

Where an old system is being removed, dismantling and disposal or recycling is scheduled first. If an existing mobile system is being moved rather than scrapped, that is a relocation project in its own right.

Documentation is agreed before mobilisation: risk assessment and method statement, SEIRS card details for the operatives attending, insurance certificates, permits to work, DBS checks where the client requires them, and agreed access times. In live buildings — hospitals, courts, working offices — out-of-hours or weekend working, screening, dust control and protection of floors and lifts are planned at this point rather than negotiated on the day.

This is the critical stage. The crew sets out the rail positions from datum lines, squares the grid to the room, and lays the rails. Each rail is then levelled along its length and across the run using a precision level, and packed with shims to correct the floor's inaccuracy. Every shim pack is cut for its position; this is patient, methodical work and it is where the quality of the installation is determined.

Rails are then fixed according to the floor construction — mechanically anchored into concrete, or mounted on a load-spreading base frame or raft where fixings are restricted, where the floor finish must be protected, or where load has to be distributed over timber joists or a thin screed. Rail joints are aligned so there is no step for the wheels to strike, and infill is fitted between and alongside the rails so the floor surface is continuous and trip-free.

End-stops are fitted at both ends of every run. These are safety-critical: they are what prevents a loaded carriage running off the end of the rail. Their presence and security is one of the first things any competent-person inspection checks.

Carriages are lifted onto the rails and checked individually for free, square and quiet running before any bays are built on them. It is far easier to correct a rail or a wheel problem now than after several hundred kilograms of steel has been assembled on top.

Bay frames and uprights are then erected on the carriages, braced and plumbed, and shelves fitted and levelled at the specified pitch. Anti-tip devices are fitted and checked on every carriage, along with brakes or aisle locks where specified, and drive mechanisms — handles, chains, shafts and gearboxes on manual systems — are installed and adjusted so that operating effort is even across every aisle.

Fascia panels, end panels and any lockable panels or aisle locks are then fitted, and shelf safe working load labelling is applied. On electric systems, a competent electrician terminates the supply and the control panel, and photocells, floor sweeps, emergency stops and aisle-entry protection are installed and set.

Commissioning is a systematic check, not a quick push of each aisle. Every aisle is opened and closed through its full travel, under load where possible, and operating effort is compared across the run. Carriages are checked for creep with no hand on the handle. Every anti-tip device is tested individually, as are brakes and end-stops.

On powered systems each safety device is function-tested separately: photocells interrupted at the correct heights, floor sweeps triggered, every emergency stop operated, aisle-entry protection verified, and controlled stopping and isolation confirmed. A safety device that is present but untested is worse than none, because it is trusted.

Shelf levels are checked, loadings verified against the rating and labelling confirmed. Any snags are corrected before handover rather than logged for a return visit.

Mobile shelving is work equipment under PUWER 1998, and Regulation 6 requires inspection after installation and before the equipment is put into service. That inspection is carried out by a competent person and produces a written report and a dated certificate — which also sets the start of your annual inspection cycle.

Handover documentation should include the PUWER certificate, the as-installed layout drawing, the system specification and load ratings, written operating instructions to satisfy Regulation 8, and the maintenance recommendation. Systems should be installed in line with BS EN 15095, the standard covering power-operated and manually operated mobile racking and shelving.

Regulation 9 requires users to be adequately trained, so handover includes operator training: how to open and close aisles safely, how to check an aisle before closing it, load limits, what not to store in the rail run, what to report, and on powered systems how to use the emergency stops. Record who attended — that record is the evidence, and it is the thing most often missing when an estate is audited.

Contents are then reinstated to the run-map, and the system is in service. Arrange the first annual planned maintenance and PUWER inspection at handover so it does not drift.

As a broad guide: survey within days of enquiry; drawings and fixed price shortly after; 4–8 weeks manufacturing lead time from drawing sign-off; then installation on site. A single small run can be installed in a day or two. A large multi-run archive with restricted access, lift-only routes or out-of-hours working can run over a week or more.

The two things that most affect the programme are access and readiness. A room that is empty, accessible and available for full working days will be installed considerably faster than one that must be worked in two-hour windows through a hospital corridor. Where the department cannot go offline, phased installation — decanting and reinstating in sections against a run-map — keeps material retrievable throughout, at the cost of a longer programme.

Are the operatives directly employed and SEIRS carded, and can you have the card numbers with the RAMS? Will the rails be levelled and shimmed with a precision level across the full run? Who fits and tests the anti-tips and end-stops? Who issues the PUWER certificate, and is it included? Is operator training included, and will attendance be recorded? What is the defects liability period, and what does the first annual service cost?

A supplier who answers all of those clearly is likely to install well. For the wider buying decision, see our guide to choosing a mobile shelving supplier.
