“…Some work has been done in this area, however. For example, Weigel et al 16 conducted experiments to study the vibration experienced when goods are transported with multi-layer stacking. They found that the vibration transmission rate of the goods in the resonance state can be reduced by choosing a pallet of greater rigidity, and a high-strength pallet can effectively reduce the resonance of the cargo.…”

This paper develops a simulated dynamics model focused on the vibration coupling between a heavy-duty vehicle and the protective structure of the payload and verifies it through field experiments, which monitor the dynamic response under complex driving conditions such as uneven surfaces, turning, deceleration, and excessive gradients in real time. Compared with the results of the experiments and the simulations (with numerical methods), it can be found that the model can accurately estimate dynamic response of protective structures. The maximum acceleration at the bottom of the protective structure becomes larger as the amplitude of the road surface roughness increases. Furthermore, when the vehicle turns, the vibration of the protective structure increases sharply with braking, and when the vehicle begins decelerating, the lateral acceleration of the freight increases significantly in the first few seconds. In addition, the maximum acceleration at the bottom of the protective structure increases with the increase in speed when the heavy-duty vehicle is driving on a gradient, but that increase is small when the speed exceeds 80 km/h.

“…Pallets typically form the ‘tertiary’ packaging component critical in developing a unitized load. Pallets provide a base for typical unit loads and aid in mechanical handling, transportation and storage of goods . It is estimated that the material handling industry in the USA has approximately 2 billion pallets, made of various materials and in many forms, being used to store and move goods at any time .…”

A carton clamp is an alternative material handling device for moving packages and material. The need for changing the clamping force for variations in size, shape and weight of the load creates the potential for underclamping (slippage) and overclamping (compressive damage). Currently, there are two test standards that provide lab-based forklift/clamp testing guidance -ISTA 3B and ASTM 6055. While ISTA provides a stationary simulation of carton clamp handling, ASTM offers a more mobile approach. The ISTA recommended testing equipment tends to be fairly expensive and is not easily accessible in North American test facilities. The ASTM standard proposes the use of a carton clamp truck in industry but does not specify any specific parameters making repeatability between laboratories and practitioners ambiguous. This study examined the implementation a carton clamp lift truck as found in industry allowing for mobile (hazard course) testing. A modified version of ISTA 3B was paired off against ASTM 6055 for evaluating both column and cross stack pallet patterns with a variety of treatments. This study attempted to determine if carton clamps as found in industry are capable and repeatable enough to provide consistent data. This study also examined the test methodologies' effect on load containment via stretch film force, load retention via unitized load slippage and the effects of ride height and driver interaction. The study sought to understand if these effects are uniform across the unitized load or if particular layers of the load are more affected than others.
