Precision high-capacity self-supporting crane system

Abstract

A precision, self-supporting crane system is disclosed that achieves high load capacity, seismic resilience, and rail-free operation through a torsional support architecture. The system includes columns interconnected by beams to form a network of moment-resisting frames, with runway beams supported by torsional corbel assemblies. Each torsional corbel assembly is a closed-section module that resists torsion, bending, and shear, maintaining precise alignment of the runway beams during operation, while providing resistance to seismic events. Flat, level beam seats define a fixed elevation for the runway beams, enabling straight, parallel alignment and allowing bridge end truck wheels to travel directly on the runway beams without ASCE rails. Alignment blocks and continuity bars connect adjacent runway beam segments to create continuous members. The result is a modular, lighter-weight crane system capable of supporting multi-ton loads on industry-standard concrete slabs typical in concrete tilt-up and industrial buildings without building tie-offs or diagonal bracing.
