A tarp deploying apparatus includes radial arm with a proximal radial arm and a distal arm. The distal arm is formed from a flexible material such as a double-walled hydraulic hose. The distal arm attaches to a tarp roller to deploy the tarp over a storage area on a trailer with at least one rear door. The radial arm is mounted on a mounting bracket secured to one of the doors. A releasable connector between the arms permits the distal arm to be separated from the proximal arm so that the rear doors on the trailer can be opened and closed without interference from the radial arm.

Particulate material trailer hopper door opening apparatus
A hopper door opening and closing apparatus operates a door on a hopper discharge opening. A pair of motorized linear actuators, each having an extendable rod, are mounted to support rails on opposite sides of the door. A bracket connects the rods to the door. A controller selectively activates the linear actuators to extend the rods and thereby move the door to an open position that permits material to flow through the lower opening and selectively activates the linear actuators to retract rods and thereby move the door to a closed position covering the lower opening.

A tarp deploying apparatus for use on a trailer includes a fiberglass tarp roller. The fiberglass tarp roller is constructed from two fiberglass tubes. A splined joint is used to join the two tubes together. Each end of the tarp roller also includes a female socket with grooves to engage splines on a motor shaft that drives the tarp roller or to connect the roller tube to a universal joint. A pin or bolt may also be used at the splined joint to securely hold the tarp roller together without the need for a welding operation.

A tarp deploying apparatus includes breakaway connector between a radial arm assembly and a tarp roller. The breakaway connector is designed to fracture, or otherwise come apart, to prevent damaging stress from being applied to the tarp roller by the radial arm assembly. Therefore, if a rear flap of a rear-dump trailer on which the radial arm assembly is mounted is dislodged from the tub of the trailer, the breakaway connect will permit separation of the radial arm assembly from the tarp roller without damaging the radial arm assembly or the tarp roller.
A tarp deploying apparatus includes radial arm with a proximal arm and a distal arm. A flexible inelastic limit element is provided between the proximal and distal arms to prevent them from crossing over center to an angle that would cause the apparatus to bind.

A tarp deploying apparatus includes radial arm with a proximal arm and a distal arm. The distal arm is formed from a flexible material such as a double-walled hydraulic hose. The distal arm attaches to a tarp roller having a splined end. The distal arm is selectively removable from the distal arm to permit a hand crank with a female splined socket to be attached to the splined end of the tarp roller to permit hand operation of the tarp deploying system when the electric motor is not functional. A mounting bracket including two feet, a pair of legs and a support span allows easy mounting of the tarp deploying apparatus.
A tarp deploying apparatus of the type that has radial arms pivotally attached at the front and rear of a trailer. A housing for supporting a tarp roll and a motor is pivotally attached at the free end of a radial arm such that the tarp roll and housing will tuck under a side lip at an upper portion of the side of the trailer. The rear radial arm is formed with a bend between the pivotal attachment point to the rear of the trailer and the free end of the radial arm, such that the free end of the radial arm is closer to the front of the trailer. A roller with enhanced traction characteristics helps to move the apparatus out of a storage position. A spring used to bias the radial arms can be adjusted to adjust the amount of biasing force.
