Abstract
A roll tarp system is provided which includes a container, a roll pipe, a tarp sized to cover an open top of the container, a power mechanism for rolling the roll pipe from a closed position in which the tarp covers the open top to an open position in which the open top is exposed, and an arm assembly having a flexible arm portion. The arm assembly biases the roll pipe toward the closed position when the roll pipe is in the open position.
Claims24
A roll tarp system comprising:
- a container having two sides, a first end, a second end, a bottom and an open top;
- a roll pipe;
- a tarp, wherein a first side of the tarp is secured to a first side of the container and a second side of the tarp is secured to the roll pipe;
- a power mechanism operably connected with the roll pipe for rolling the rotating the roll pipe for rolling the roll pipe from a closed position in which the tarp covers the open top to an open position in which the open top is exposed;
- and
- at least one flexible assembly, wherein one end of the flexible arm assembly is attached to the container and a second end of the flexible arm assembly is connected to the power mechanism;
- wherein the flexible arm assembly biases the roll pipe toward the closed position when the roll pipe is in the open position.

A roll tarp system, comprising:
- a container having two sides, a first end, a second end, a bottom and an open top;
- a roll pipe;
- a tarp, wherein a first side of the tarp is secured to a first side of the container and a second side of the tarp is secured to the roll pipe;
- a power mechanism for rolling the roll pipe from a closed position in which the tarp covers the open top to an open position in which the open top is exposed;
- and
- an arm assembly connected between the container and the power mechanism;
- wherein the roll pipe is rotatably disengageable from the power mechanism by operator manipulation of a release mechanism;
- and
- wherein the arm assembly comprises an arm mount connected to the container, a flexible arm portion connected to the arm mount, and a rigid arm portion connected between the flexible arm portion and the power mechanism, and wherein the flexible arm portion biases the roll pipe toward the closed position when the roll pipe is in the open position.
