Lifting Equipment
Technical Reference
Specifications, configurations, applicable standards, and duty classifications for every major lifting and material handling equipment category.
Overhead / EOT Cranes
Bridge cranes, gantry cranes, monorail and underslung systems for industrial facilities. Duty classifications FEM A1–A8 covering workshops to continuous steel plant operations.
Hoists & Winches
Electric chain hoists, wire rope hoists, pneumatic hoists, and winches for lifting and pulling. Selection governed by FEM mechanism group M1–M8 and operating hours.
Mobile Cranes
All-terrain, rough terrain, crawler, and truck cranes for project and industrial lifting. Load chart reading, outrigger ground bearing, and site access planning are critical for safe operation.
Rigging & Lifting Gear
Wire rope slings, chain slings, synthetic webbing, shackles, hooks, and below-hook lifting devices. WLL reduction factors, inspection intervals, and rejection criteria per ASME B30.9 and EN 818.
Material Handling
Conveyors, stackers, reclaimers, bucket elevators, and bulk handling systems for ports, power plants, and process industries. Throughput calculations and system integration.
Offshore & Marine Cranes
Pedestal cranes, knuckle boom cranes, subsea lifting systems, and heave-compensated equipment for offshore platforms, FPSOs, and marine construction vessels.
Tower Cranes
Luffing jib, hammerhead, flat top, and self-erecting tower cranes for construction and infrastructure. Anchoring systems, mast climbing procedures, and safe working load tables.
Load Testing & Inspection
NDT methods, proof load testing, dynamic load testing, and inspection protocols for in-service and commissioning testing. Statutory requirements vary by jurisdiction.
