BB7750/HD Breaker boom

Sandvik Large Range booms are specially designed for mining markets. Proven design combined to over dimensioning makes this a convenient and safe choice.

Large Range booms also feature a multi-fit pedestal, which makes replacing existing, worn-out boom systems more convenient. In addition the number of different parts is cut to minimum by e.g. fitting same cylinders for all boom functions.
