VIDEO: Built For It Trials – Gravity

World Coal,

Caterpillar has launched a new series of short films, aimed at showcasing the versatility of their equipment used in mining operations. The films feature Caterpillar’s Built For It trials.

In their latest film, Sir Isaac Newton’s theory of universal gravity puts the company’s B15 smartphone to the test.

In the short film ‘Gravity’ (not featuring George Clooney or Sandra Bullock), a Cat MH3049 Material Handler drops a phone into a pool of water from 35 ft. Then, a Cat 277D Multi Terrain Loader runs over 600 phones placed on the ground.

Watch the video below to see how the phones fared.



The B15 smartphone has been built to be as rugged as the much larger mining equipment found on coal mining sites. In operations where communication is vital, mineworkers and managers can stay in touch using the B15, which has 16 hours of talk-time, can survive long falls and can be used in wet conditions.

The phone has a rubber and aluminium shell with an Android 4.1: Jelly Bean operating centre. It also features a 5 megapixel camera and a dual-core 1 GHz processor.

The B15 is just shy of 5-inches, with a width of 2.7-inches and .58-inches of thickness. At just 5.9 oz, the phone is also light, while the rubber body casing and aluminium sides “give it the look of a toolbox or an eye-catching screwdriver”, according to reviewers.
