Abstract: A drop-deck trailer for hauling heavy loads (e.g., jumbo glass panes) positioned on each side of the drop-deck and which minimizes trailer twisting/leaning is provided. The drop deck includes a plurality of transversely-mounted A-frames that are coupled through an anti-torsion structure (ATS) to each other and to at least two trailer main beams at an elevated front deck and at a rear portion of the drop-deck for transferring the load from each side of the trailer and into the at least two main beams. The ATS includes tie bars for connecting the tops of the A-frames together, a front support for connecting the forward-most A-frame to the main beams and an end support for connecting the rear-most A-frame to the main beams. The ATS minimizes twisting/leaning of the trailer without adding any significant weight to the trailer itself. This permits the transport of increased payload on the trailer, including a continuous tarp for covering the payload during transport.

Abstract: Transport arrangements for cutting heads or the like have previously been configured as independent one or two-axle trailers upon which the implement could be deposited. The disadvantage is that thereby a self-supporting construction is required which entails high costs. In another known embodiment a two wheel trailer is attached to both the front and the rear end of the implement, which is costly and increases the length of the complete rig. The transport arrangement proposed consists of a draft tongue and a trailer, where the tongue is inserted into and secured to the implement and the trailer is attached underneath the implement. Transport arrangements of this type are used to transport agricultural implements.
