Definition
The weight of temporary or movable loads placed on a pallet, racking structure, or warehouse floor, as distinguished from the permanent (dead) load of the structure itself. In pallet racking design, live load refers to the weight of palletized goods stored on the racks. Racking systems are rated for maximum live load per beam level and per bay, and exceeding these ratings creates serious safety hazards.

Static Load
The maximum weight a pallet can safely support when resting on a flat, level surface without being moved. Static load capacity is the highest load rating for most pallets because the weight is evenly distributed across the bottom deck. A typical GMA pallet has a static load capacity of 2,500 to 5,000 pounds. Static load ratings are relevant for floor storage and long-term warehousing applications.
Dynamic Load
The maximum weight a pallet can safely support while being moved by a forklift or pallet jack. Dynamic load capacity is lower than static load capacity because the pallet is subject to additional stresses from acceleration, deceleration, turning, and uneven floor surfaces during movement. A typical GMA pallet has a dynamic load capacity of 2,000 to 2,800 pounds. Dynamic load ratings are critical for transportation and material handling operations.
Racking
The practice of storing loaded pallets on elevated warehouse racking systems (pallet racks). Racking places unique demands on pallet strength because the pallet spans across the rack beams with its load weight concentrated on the supported edges rather than distributed across a flat floor. A pallet's racking capacity is typically its most demanding load rating, and not all pallets are suitable for racking. Rackable pallets must be specifically designed and rated for this application.
Payload
The total weight of the goods placed on a pallet, excluding the weight of the pallet itself. Payload capacity is determined by the lesser of the pallet's load rating and the handling equipment's lifting capacity. Maximizing payload per pallet while staying within weight limits is a key objective in logistics optimization. Payload weight must also be considered in relation to trailer weight limits and road transport regulations.
