Container covering system

摘要

A container covering system for open truck containers provides enhanced control and maneuverability of a tarp for covering containers of different sizes. A tarp can be extended and retracted under rotary movements of elements of the system to adapt for different lengths of containers. A tarp device includes the tarp, which can move between a stowed position and an extended position to cover the top of an open container. A pair of forward arms are pivotable with respect to a first pivot axis defined on the device. A pair of rear arms are pivotable respect to second pivot axis that is defined on the rear ends of the forward arms. A cross member extends between the end of the rear arms which are opposed to the second pivot axis. The cross member retains the leading end of the tarp and is movable with the rear arms. The rear arms are biased to rotate towards the rear end of the container. A biasing member is configured to rotate the rear arms around the second pivot axis. A torque generating device applies a resistive force on the tarp against the rotational bias of the rear arms to retract the leading edge of the tarp.
