Work Across Southcentral Alaska
Featured in Hitachi Breakout Magazine
"The performance of the ZX160 allows me to do work that many brands would need to provide in their 200-210 size excavators. The hydraulics are exact, helping me do my precision grading for foundation pads and driveways."— Brian Harten, Owner & Operator, BTH Construction | Hitachi Breakout Magazine, Winter 2020
BTH Construction was featured throughout the official Hitachi ZAXIS-6 Series product catalog — covering the ZX130-6, ZX135US-6, and ZX160LC-6 — when Brian took delivery of a new ZAXIS 160LC-6. BTH’s real-world work on Alaska job sites is showcased across multiple pages of the catalog, a recognition that joins a family tradition of Hitachi ownership stretching back to Brian’s father’s UH045 in the mid-1980s.
