Technical Engineering

Horizontal and Diagonal Braces

Members generally welded between frame columns to resist cross aisle forces imposed on frames and brace the columns.

Load Capacity

The maximum total weight that can be handled by material handling equipment, without sacrificing any of the applicable published specifications of the equipment.

Load Factor 

Factor that accounts for deviations of the nominal load from the actual load, for uncertainties in the analysis that transforms the load into a load effect and for the probability that more than one extreme load will occur simultaneously.

Load Height

Maximum overall dimension from the bottom of a pallet or load module to the top.

Load Length

Maximum overall dimension of a pallet or load module, measured in the direction perpendicular to the length of the aisle for conventional fork truck handling. Automated systems may store loads with length in parallel to the aisle length. Load length may exceed the pallet dimension with product overhang.

Load Width

Maximum overall dimension of a pallet or load module and load in the direction parallel to an aisle for conventional fork truck handling, or perpendicular to the aisle for automated systems.

Local Buckling

Buckling of a compression element within a cross section

LRFD (Load and Resistance Factor Design) 

Method of proportioning structural components such that the design strength equals or exceeds the required strength of the component, under the action of the LRFD load combinations.

LRFD Load Combination

Load combination in the applicable building code intended for strength design (load and resistance factor design).

MTBF (Mean Time Between Failures)

The average time between two failures, otherwise a measure of the trouble free time.

MTTR (Mean Time To Repair)

The average time to complete a repair.

NBCC (National Building Code of Canada)

Provides building standards.
