Adjustable Pallet Racking (APR)

Adjustable pallet racking is a pre-engineered rack construction system designed to meet a wide range of industrial storage needs and is one of the most widely used palletized storage equipment. This system is bolt free and can easily be adjusted. The racking system consists of two basic components – the frame and the beam. Frames and beams in this racking system can be used together in standard or modified form. Together with a number of accessories, it can produce an almost unlimited variety of storage solutions. The frames of the rack are constructed in a way that it is being welded and it comprised of two uprights alternate horizontal and diagonal braces and two base plates. Beams are usually manufactured from boxed steel section with beam connector brackets welded to either end. Beams fitted to frames are secured against accidental dislodgement by a locking pin inserted into the locking pin slot in each beam connector bracket. Beams are adjustable vertically; this basic adjustability cannot be varied.


Locking pins
In adjustable pallet racking, the frame and the beam is held together using locking pins. The locking pins are 3mm thick and zinc plated. The locking pin prevents accidental dislodgement of the beam and the shape of the pin is similar to that of a question mark. Two pins are used to secure each beam. The locking pin would not be vibrated out of position even if it were halfway out of the slot.

Eight cold-formed bends in the upright’s section give it exceptional strength-to-weight performance and excellent resistance to twisting Frame uprights are punched with a slot pattern that permits the insertion of beam connector brackets. The outside pair of slots on the upright is rectangular.

Advantages of APR:
-Beam height is adjustable for different pallet load heights
-The racks can be dismantled and moved.
-There is a random access to every pallet
-Damaged parts can be easily replaced.
-It is not expensive.

Disadvantages of APR:
-Low space utilization due to the reason that fork truck aisle give access to only two rows of racking.
-For racking above 8m in height, a chemically treated floor is needed to stabilize the racking with the load.
