POWERING THE TEAMS WHO POWER COMMUNITIES.
WHO WE SERVE // UTILITY & BROADBAND CONTRACTORS
We keep your digger derricks, bucket trucks, and support fleets ready for the next job.
DIGGER DERRICK & BUCKET TRUCK REPAIR & SPECIALTY SERVICES
We offer full-service, in-shop repairs for digger derricks, bucket trucks, utility fleet vehicles, and broadband service rigs. Whether you’re placing poles, setting anchors, or trimming lines, we understand the pressure your crew and equipment are under to perform reliably every day. From hydraulic lifts to winch systems and outriggers, we service and rebuild every critical component to OEM spec—because when you're working the line, "good enough" doesn't cut it.
HYDRAULIC SYSTEMS
INSPECT | | DIAGNOSE | | REPAIR | | REBUILD
Troubleshoot and repair hydraulic circuits, directional valves, pumps, motors, and cylinders.
We handle hose replacements, hydraulic leaks, flow loss, and system overheating. Pressure test and restore functionality to OEM spec or better with clean, efficient routing and robust sealing.
We service boom lift hydraulics, outrigger systems, and control circuits to maintain safe, stable operation in the field.
WINCHES, SHEAVES, & CABLES
INSPECT | | DIAGNOSE | | REPAIR | | REBUILD
Service and calibrate lifting systems, including hydraulic winches, sheave wheels, cable drums, and tension assemblies. We repair or replace damaged lift cables, worn fairleads, and sticking spools to keep your load-handling systems safe, responsive, and ready for field use.
OUTRIGGERS & STABILIZERS
INSPECT | | DIAGNOSE | | REPAIR | | REBUILD
Repair hydraulic outriggers, pads, and stabilizer arms to prevent tipping and ensure level operation during elevated work. Hose replacement, cylinder reseal, and full pad rebuilds available.
FABRICATION & MODIFICATIONS
INSPECT | | DIAGNOSE | | REPAIR | | REBUILD
Custom fabrication to fit your workflow — from toolboxes, control mounts, and step frames to full rig remounts or bracket rebuilds. We engineer solutions to real-world field problems like recurring cable snags or operator obstructions. Need a step box extension, tool cage, or safety railing installed? If it’s been hacked together before, we’ll build it better.
AUGER DRIVES & TORQUE HEADS
INSPECT | | DIAGNOSE | | REPAIR | | REBUILD
Disassemble and rebuild pole-setting auger drives, including gearboxes, output shafts, and drive couplings. We service hydraulic-powered and mechanical drive systems, ensuring torque delivery, shaft alignment, and smooth auger feed for reliable penetration across varying soil conditions.
PREVENTATIVE MAINTENANCE
INSPECT | | DIAGNOSE | | REPAIR | | REBUILD
Keep your trucks running without interruption. Our preventative maintenance plans are built around your equipment, your schedule, and your workload — not a cookie-cutter checklist. We perform oil changes, fluid top-offs, filter replacements, and system checks based on usage hours and operating conditions.
Clients enrolled in a PM plan receive priority scheduling, service reminders, and the option to have fluids and filters pre-stocked at our shop for fast turnaround. We track wear patterns, flag early warning signs, and help prevent expensive breakdowns before they happen
ELECTRICAL SYSTEMS
INSPECT | | DIAGNOSE | | REPAIR | | REBUILD
Troubleshoot rig electrical issues including start-up failures, short circuits, and low-voltage dropouts. We repair or replace custom wiring harnesses, switch panels, sensor connectors, and control boxes — with clean routing, sealed terminations, and function-first design for field durability.
We also service boom control panels, lighting systems, and strobe/beacon wiring to keep your crew safe and visible.
BOOM & BUCKET SYSTEMS
INSPECT | | DIAGNOSE | | REPAIR | | REBUILD
Service and adjust articulating and telescoping boom arms, buckets, and lift controls. We inspect pivot points, bucket liners, and upper control functions for smooth, safe operation.
