BART-1

Hand Cranked Blasting Machine with Line Continuity Tester

BART-1 is a medium energy hand cranked blasting machine that comes with a built-in line continuity tester. It uses a hand generator and the operator does not need an external power supply or batteries. The blasting machine is portable, compact and lightweight, and can easily be operated by a single person.

The integrated line tester verifies the line’s integrity and uses a two color LED that indicates to the user whether the resistance of the line and detonators is below or above 700 Ω, in accordance with Class 1 detonators. For safety reasons, the line tester current is limited to 1 mA.

BART-1 includes an output pulse tail cutting to limit the impulse to 4ms and quench the remaining capacitor charge. These safety features are necessary to eliminate potential secondary explosions of the flammable dust generated during the blast.

The device comes in an aluminum enclosure that includes ON--OFF/L-test switch, terminal for connection of electric detonator lines, two color LED for line testing and a crank handle for capacitor charging. Both sides of the panel include “READY” LEDs to indicate the capacitor charge state.
