20140041961 | FLATBED LOADING SYSTEM WITH SELF-ALIGNING PLATFORMS - A mobile platform has a separate and independent linear actuator pivotally connected near each opposite end of the platform where there is a contact limit switch that when triggered by contact with the side of a flatbed, stops movement of the actuator, and thus stops movement of the platform, toward the side of the flatbed. Because each of the two actuators is pivotally connected to its respective end of the platform and moves independently of the other, each end of the platform can stop moving toward the flatbed before or after, depending on how the flatbed is misaligned, the other end of the platform stops moving toward the flatbed. In this way the platform self-aligns to the alignment of the flatbed and avoids the need to reposition a flatbed that is not precisely aligned parallel to the central axis of the loading bay. | 02-13-2014 |
