RKL-SR90

SR-90 Selective Pallet Racking

The default adjustable beam racking: every pallet reachable from an aisle, beam levels moved by two people with a rubber mallet.

Bolt-free beam connector with two safety pins per end, adjustable on a 50 mm pitch
Bolted bracing, so a damaged diagonal is replaced without cutting the frame
Base plate takes an M12 anchor plus a shim pack for out-of-level floors
Beam capacity per pair and bay load both printed on the as-built layout

Product detail

SR-90 is the system most buildings should start from. Every pallet position faces a working aisle, so a truck reaches any pallet without first moving another one, and stock rotation follows whatever your WMS decides rather than whatever the lane allows.

Two load figures, not one

A beam pair carries the pallets sitting on it. The upright frame carries every beam pair in that bay plus its own weight. These are separate numbers and they fail in separate ways, so both appear on the layout drawing: beam capacity per pair for the heaviest single level, and bay load for the total of all levels together.

Adjusting the levels

Beam connectors are bolt-free. The connector lugs drop into the upright perforation on a 50 mm pitch and two safety pins per end lock the beam down. Moving a level is a two-person job with a rubber mallet, which matters the first time a pallet height changes and 400 beam levels have to follow it.

Frames

Uprights are roll-formed from structural strip in a 90 x 70 mm section at 1.8, 2.0 and 2.5 mm gauge. Bracing is bolted rather than welded, so a diagonal hit by a fork is replaced without cutting the frame out of the run. Base plates take an M12 anchor and a shim pack for floors that are not as flat as the drawing assumed.

Deflection and damage

Beams are designed to a deflection limit of span/200 at full rated load. That figure is what a periodic inspection measures a loaded beam against, so it is printed on the layout drawing rather than left in a catalogue.
