Cranes TRIZ Cases

Horizontal actuators rotate a vertical column, reducing base weight and vehicle load capacity limits.

Segmented counterweights reduce carriage complexity while maintaining lifting capacity through a dynamic activation sequence.

A rod guying system with guide holders and displaceable tension rods secures telescoping jib sections on mobile cranes.

Segmented tubular supports attach to crane pads and hold a flexible barrier, eliminating heavy barrels that obstruct worker movement.

A grappler overload protection system estimates load weight using arm spread sensors to prevent unsafe lifting conditions.

Segmented superstructure blocks use pin connections to maintain structural strength while reducing transportation complexity.

A foldable crane assembly uses a receiving section on the lift boom to pivot an articulated boom closer to the central axis.

A combi-angling plate integrates with a hydraulic cylinder to orient a mobile crane main jib extension.

A telescopic mast guidance unit uses a roller and pad to support sliding arms.

Stacking wider additional sections above main parts distributes forces via bolt connections, resolving collision risks during transport.

Self-aligning guide faces on positioning pins engage rear frame surfaces before pin hole alignment, eliminating manual force and reducing assembly time.

Step pin shoulder adjusts axial clearance to resolve installation jamming while maintaining structural stability.

A compact drywall lifting apparatus uses a cable hoist to move heavy construction materials across uneven terrain.

Adjustable frame parts on the assembly device enable self-assembly of guy supports, reducing transport width and eliminating external assistance.

A segmented lattice piece uses releasable connections to adapt boom cross-sections for variable crane loads.

A computing device calculates minimum distances between a crane boom and obstacles to constrain movement within defined volumes.

A tower crane control unit detects autorotation or oscillation states using angular velocity and orientation angle data from an integrated sensor.

A cross-section change adapter couples a rectangular first jib part to a triangular second jib part on a luffing crane boom.

Segmented guy mast extension beams bolt to base supports, resolving the trade-off between increased lifting capacity and device complexity.

A crane support assembly uses rigid braces to transfer bending moments and shear forces from the tower frame to an outrigger.

Hydraulic actuators drive boom folding through rotary joints, resolving maintenance access conflicts while preserving telescopic mast adaptability.

Multiple sheaves redirect wire ropes in a telescopic crane boom, lowering tension forces to reduce boom weight while maintaining load capacity.

A carrier plate mounts a loading crane on chassis side members.

A rotation sensor detects slew ring position via a bevel pinion and reduction gearing system.
