## Abstract

The Sand Hand is a piece of mobile equipment that mounts on an open top tank and filters out and weighs frac sand in an oil field well test. It is faster, easier and more cost efficient to rig up, rig down and mobilize. It makes the process of weighing frac sand faster, it weighs frac sand more accurately, it makes it safer to access and operate, more user friendly to operate and much cheaper to build.

## Claims

### Claim 1

The body of the sand hand is a cyclonic gas buster that reduces the high-pressure slurry to atmospheric pressure while separating the gas from the slurry and reroutes it to a gas discharge tube.

### Claim 2

The sock rotates on the carriage 180 degrees and locks into place, the bottom sock holder slides up and down as the cable is jerked dumping the captured sand and shakes any residual sand from the sock.

### Claim 3

When the scale is lifted to weigh the sand, the scale lifts the filter sock, freeing it from the sand collection equipment, making the empty weight under 6 lbs, allowing the scale to give a more accurate weight.

### Claim 4

The sand hand has a working deck with individually mounted steps and handrails making it a custom fit to any height tank, also making it easier and safer to access and operate.
