Abstract
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.
Claims15
A tarp deploying apparatus comprising:
- a mounting bracket attached to a rear flap of a tub of a rear-dump trailer;
- a proximal radial arm pivotally mounted to the mounting bracket;
- a distal arm extending from the proximal radial arm, the distal arm being flexible;
- a universal joint at a free end of the distal arm, the universal joint including a connection portion for selective connection to a rear portion of a tarp spindle;
- a tarp rolled upon the tarp spindle, and
- wherein a rear portion of the tarp spindle includes a spline portion for engagement with a hand crank when the connection portion of the universal joint is disconnected from the tarp spindle.
A tarp deploying apparatus comprising:
- a mounting bracket attached to a rear flap of a tub of a rear-dump trailer;
- a proximal radial arm pivotally mounted to the mounting bracket;
- a distal arm extending from the proximal radial arm, the distal arm comprising a double-walled hydraulic hose;
- a universal joint at a free end of the distal arm, the universal joint including a connection portion for selective connection to a rear portion of a tarp spindle;
- the tarp spindle having a tarp rolled upon the tarp spindle.
A mounting bracket for a tarp deploying apparatus of the type that includes a radial arm that supports a tarp roll, the bracket comprising:
- a first foot including a first plurality of mounting holes;
- a second foot laterally spaced apart from the first foot, the second foot including a second plurality of mounting holes, the second foot having a first end and second end, the first end of the second foot being closer to the first foot than the second end of the second foot;
- a first spacer leg having a first end at the first foot and a second end opposite from the first end, the first spacer leg extending generally perpendicularly from the first foot;
- a flat support span having a first end and a second end, the first end of the flat support span extending from the second end of the first spacer leg such that the flat support span is generally parallel to and covering the first foot;
- and
- an angled spacer leg extending at an obtuse angle from the second end of the flat support span to the first end of the second foot.
