Keep the site moving when the electronics stop.
Component-level repair and calibration for crane controls, load indicators, DG controllers and site automation. Diagnosed in Chennai, returned tested and documented.
Seven service lines built around site equipment
Control and safety electronics across cranes, generators and heavy machinery — repaired, calibrated and load-tested before they go back to work.
Crane Control Panel Repair
Diagnosis and rebuild of control boards, relay logic, contactors and wiring harnesses on industrial lifting machinery. Failed panels are stripped, fault-traced at component level and reassembled to the original schematic, then run through a functional test before dispatch.
Load Moment Indicator (LMI)
Sensor diagnostics, control module repair, display servicing and full recalibration of load moment systems. An out-of-spec LMI reads the wrong moment long before it fails outright, so every unit is re-zeroed and verified against known loads.
Safe Load Indicator (SLI)
Controller troubleshooting, sensor adjustment, cable and wiring repair, and end-to-end system validation for construction and industrial cranes. We restore accurate load measurement and confirm cut-out behaviour before the unit returns to site.
Diesel Generator Controllers
Repair of DG controller boards, power modules and fault-annunciation circuits for standby and prime power sets. Includes reconfiguration of trip settings and verification of start, transfer and shutdown sequences.
Weighing & Load Monitoring
Load cell diagnostics, indicator servicing, control board restoration and calibration for weighing systems on construction and material handling equipment. Measurement drift is corrected against reference weights and documented.
Site Automation & Control
PLC repair, sensor replacement, panel troubleshooting and embedded system diagnostics for automated site equipment. Programs are backed up before work begins and restored on completion so the machine returns configured as it left.
Power Supply & Industrial PCB
Component-level diagnostics on SMPS units, inverters and industrial PCBs — capacitors, IGBTs, gate drivers and regulation circuits. Repaired boards are load-tested at rated capacity before they are signed off.
Why contractors send equipment to GRD
Project schedules do not wait for a control board. Our work is set up to get a fault identified fast, priced honestly, and returned in a condition you can sign off on.
From breakdown to back on site
Safety and compliance are part of the repair
Lifting and power systems are inspected assets. Every unit leaves calibrated within defined limits, with paperwork your safety officer can file.
What a repair changes
Comparison against buying a replacement unit through an OEM channel.
| Factor | OEM replacement | GRD repair |
|---|---|---|
| Typical cost | Full unit price | A fraction of replacement |
| Lead time | 2–8 weeks, import dependent | 3–5 days, emergency slots |
| Discontinued models | Often unavailable | Routinely repaired |
| Fault report | Rarely provided | Written report every job |
| Calibration | Factory default | Set to your site conditions |
| Testing | Factory test certificate | Load tested, report included |
