Runway rail laser survey
Millimeter-grade optical alignment corrects rail span skew, elevation dips, and wheel flange wear across long travel runway girders to protect structural steel from lateral fatigue.
Control panel modernization
Replacement of obsolete contactor banks with variable frequency drives, regenerative braking resistor banks, and modular festoon power systems configured for high ambient shop temperatures.
Electro-hydraulic thruster brakes
Complete teardown, lining renewal, torque spring calibration, and release clearance tuning for critical hoist holding brakes to ensure safe working load containment under dynamic stop cycles.
Wire rope spooling overhauls
Precision groove depth gauging on fabricated rope drums, magnetic rope defect testing, and laser sheave alignment to prevent premature wire strand abrasion and sudden tensile failure.
Four-phase overhaul protocol
NDT & Deflection Audit
Component Teardown
Precision Re-machining
Proof Load Stamping
Ultrasonic weld inspection, hook trunnion magnetic particle audits, and laser camber deflection measurements establish baseline structural integrity before mechanical disassembly begins.
Crab trolleys, gear reducers, and wheel bogies are dismantled on-site or staged in regional hubs for ultrasonic crack testing, bearing extraction, and shaft tolerance mapping.
OEM-spec replacement of heat-treated crane wheels, bronzed bushings, and high-tensile rope drums, paired with dynamic vibration balancing and laser gear backlash tuning.
Static proof testing at 125% safe working load and dynamic commissioning across travel limits under certified competent inspector witness strictly conforming to the Indian Factories Act.
