Car crusher

Cars can be crushed either dropping heavy weights onto them, using an excavator bucket or mechanical grab, but these rudimentary means can be time consuming and produces inconsistent scrap sizes.

By contrast, having a dedicated car crushing machine speeds up the compacting process and results in more uniform scrap bundles.

Both types can be mounted onto a semi trailer - the transportable mobile car crusher - to allow it to crush and collect vehicles from multiple junkyards who do not own their own machine.

Shredding machines also have a crushing action which will reduce the height of the vehicle before it is finally pulverised into fragments by spinning rotors.

The car scraps are flattened into dimensions of six inches tall by five to six feet wide, similar to the length of its original size.

The mobile car crusher was invented by Charlie Roy Hall in the city of Wadley, Georgia in the year 1996 and was patented on August 12, 1997.

They generally consist of two hydraulically powered hinged "wings", which fold the vehicle in half, pressing it into a rectangular "log".

The other type are industrial shredding plants which are usually built on a very large scale - these employ a giant pair of rollers which flatten the hulk and feed it into the main hammermill.

They have appeared in such well known films as Goldfinger (destroying a Lincoln Continental with a body inside[3]), Cleopatra Jones, National Lampoon's Vacation,[4] I'll Never Forget What's'isname, Kick-Ass, Superman III,[5] Gone in 60 Seconds,[6] Pulp Fiction, Strul, Mickey One, and many others.

A car crusher was used to dispose of Walt and Jesse's RV containing a mobile meth lab in season three of Breaking Bad.
