Load-Engaging Girders TRIZ Cases

Form-fitting plug-in transverse plates cut box girder alignment and tack welding, enabling faster external welding and better seam quality.

Form-fitting transverse plate connections pre-position crane box girder parts, eliminating tack welding and improving access for automated welding.

A rail-mounted collapsible gantry lifts heavy server hardware in immersion tanks, reducing manual handling hazards and downtime.

Angled header beams and a moveable hoist simplify placement and replacement of refractory blocks and checker bricks in glass furnace structures.

Synchronous self-climbing tower bodies form a stable rectangular platform that raises hoisting capacity for high-rise construction.

A clamping device lower part uses a segmented extension and curved transition to eliminate notch cases and boost fatigue strength.

A wall-mounted overhead rail assembly uses a spring-loaded pin to lock the cross-rail to an attachment bracket.

Planar struts with recesses enable self-aligning chord insertion, reducing dead weight and production costs.

A main beam with a thicker upper C-beam and thinner lower C-beam reduces spreader weight while maintaining structural strength.

Releasably secured flat braces segment the truss girder, resolving manufacturing complexity while maintaining structural strength.

Circumferential gap between stationary and movable dies pre-positions metal sheets, eliminating bulkhead plates to reduce production time.

An external slide joint on the end girder absorbs rail misalignment, reducing wear and manufacturing costs.

Aligning rope drum axle parallel to the main support structure reduces lateral tipping risk while maximizing hoisting height.

Folded planar struts optimize buckling resistance while reducing dead weight and production costs in bridge and gantry crane girders.

Intersecting planar struts form an X-shape in the girder, boosting torsional rigidity while eliminating vertical posts to reduce dead weight.

A hollow profile uses a passage opening and sealing compound to attach add-on parts without weld seams.

Detachable flattened braces replace welded joints in trussed crane girders, reducing manufacturing complexity and transportation costs.

Reversed tongue-and-groove web joints in a crane girder splice minimize welding heat input and simplify assembly alignment.

Self-service trolleys guide boom segments to extend the crane without external heavy equipment, cutting construction time and costs.
