BART-2
Hand Cranked High Energy Blasting Machine
BART-2 is a powerful high energy hand cranked blasting machine. The device 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.
BART-2 can be used to detonate most insensitive electric detonators that require high energy to detonate, including class C4 highly insensitive detonators.
The blasting machine includes a number of important safety features to avoid accidental detonation. The crank handle can be removed by the operator when the firing line and the detonators are inspected, or not ready to be fired yet. BART-2 also includes a mechanical safety cover above the terminals that prevent cranking when the line is connected. Lastly, there are two FIRE buttons that need to be pushed simultaneously for detonation.
The device comes in an aluminum enclosure that includes ON-OFF/L-test switch, terminals for connecting electric detonator line, and a crank handle for capacitor charging. Both sides of the panel include “READY” LEDs to indicate the capacitor charge state.
To test the line resistance, Englo’s OOM-4 digital line tester should be used.
