Abstract: A roll-up tarp apparatus for attachment to an open-top truck trailer, with a flexible tarp that rolls onto and unrolls from a roll bar as the roll bar rolls across the trailer. The roll bar is connected to the trailer by two telescoping arms which each have a lower portion that slides within an upper portion to telescope and adjust the length of the telescoping arms as the roll bar rolls across the trailer. The telescoping arms each have two bearings, which are on opposite sides of the telescoping arm and which are separated along the length of the telescoping arm, so that when forces are applied to the telescoping arm during use, the bearing surfaces aid in sliding the lower portion within the upper portion.

Abstract: Mud flap assemblies including a frame, a securing assembly and mud flap panels; the securing assembly enabling the frame to be secured to a hitch assembly having a shaft, for further attachment to a hitch receiver secured to a vehicle; the frame having two side portions secured to a center portion to which the securing assembly is attached. The center portion of the frame is preferably configured to rest on a portion of a bumper of the vehicle to minimize vibration of the frame during use. The frame includes two side portions having channels within which reside at least a portion of fasteners that attach mud flap panels to each of the respective side portions. Methods of installing mud flap assemblies and attaching the flap panels are also disclosed.

Abstract: A roll-up tarp assembly including front and rear arm assemblies and an extended modified roll tube. The front arm assembly includes a drive assembly that drives an output shaft. The output shaft is removably connectable to the roll tube. The connection between the output shaft and the roll tube has two distinct modes. The output shaft can be removably connected to the roll tube with a clevis pin such that the output shaft and the roll tube rotate together or the output shaft can be retained within the roll tube by a roll pin residing in a peripheral grove in the output shaft so that the output shaft may rotate independently of the roll tube. Methods of installing and using the roll-up tarp assembly are also disclosed as well as methods and kits for converting a manually operated assembly to a motorized assembly.

Abstract: A motorized conversion kit for converting manually operated roll tarps includes front and rear arm assemblies and a roll tube extension. The front arm assembly includes a drive assembly that drives an output shaft. The output shaft is removably connectable to the roll tube extension that is connected to a modified roll tube. The connection between the output shaft and the roll tube extension has two distinct modes. The output shaft can be removably connected to the roll tube extension with a clevis pin such that the output shaft and the roll tube extension rotate together or the output shaft can be retained within the roll tube extension by a roll pin residing in a peripheral grove in the output shaft so that the output shaft may rotate independently of the roll tube extension. Methods of installing and using the conversion kit are also disclosed.

Abstract: Mud flap assemblies including a frame that can be interconnected to a hitch assembly which can be interconnected to a hitch receiver. Mud flap assemblies including a frame, a securing assembly and mud flap panels; the frame having two longitudinal ends and a rear plate that includes a hitch opening spaced for receiving the shaft of the hitch assembly. One frame is designed to rest on a portion of the bumper to minimize vibration of the frame while in use. The mud flap assembly may include a pair of stops or stop assemblies that are preferably adjustable and are constructed and arranged to rest against the bumper. The mud flap assemblies may also include exhaust ventilation apertures and/or protective heat shields. Methods of installing mud flap assemblies are also disclosed.
