Lifting Devices TRIZ Cases

A movable load-bearing component and limiting holes enable fast coarse positioning, then screw-driven fine lift with fewer crank turns.

A height-adjustable platform raises workers in unison to reduce reaching strain and improve stable part retrieval along conveyors.

Point-cloud road mapping estimates flat and hidden lower surfaces to detect steps reliably despite slope changes and occlusion.

Sensor-verified stabilizer jacks and tilt checks block scissor-lift raising until the trailer is level, reducing deployment accidents.

An actuator-assisted lift stores and releases energy to move heavy insulated spa covers into a compact stored position with less manual effort.

A trolley-mounted rotating single-arm platform extends front girder construction reach on existing bridge cranes while improving handling and safety.

A fork arm switches between electromagnet and clamp fixation after detecting pallet magnetism, securing metal and non-metal pallets safely.

A retractable floating hook lets AGV fork arms avoid collision damage and lift short pallets without precise hook alignment.

Electromechanical fork tilt replaces driver-dependent mast adjustment to deliver precise load positioning with lower maintenance and no hydraulic oil.

A liftable roller table lets AGV trolleys take skids directly from skid conveyors, avoiding complex transfer stations and simplifying plant transport.

Autonomous robots move empty and full containers between induct, pick, and buffer stations to cut sortation bottlenecks and manual handling.

Flexible drive belts and synchronized wheels replace linkage joints in a warehouse shuttle to reduce jamming, noise, and package damage.

Top plates, lacing members, and gusset plates reinforce aerial ladder sections to distribute loads and resist extreme bending stress.

A swept light plane above the fork detects loads with holes or bores reliably, avoiding shelf changes and manual verification.

A movable plate and door connecting structure let the stacker crane open facility doors without separate power equipment, saving space and complexity.

A compliant flange seals textured utility covers so vacuum pressure can lift heavy lids with less manual effort and more reliable attachment.

Sensors and a movable counterweight automatically offset payload shifts in telescoping cranes to maintain balance and prevent unexpected motion.

A threaded rod and worm-gear lifter raises a heavy display into wall-mount alignment, enabling safe one-person installation.

Spring clips and hard stops secure the jack foot while the crowned pad spreads load, reduces sinking, and protects uneven ground.

Spring-biased locks automatically secure and release cribbing blocks, reducing manual lifting intervention and maintaining load support if hydraulics fail.

A grip-driven actuation rod and resilient sheet let the jack retract gradually without manual support, improving descent control and user handling.

A tapered pivot socket and arcuate frame help a cam jack grip the axle securely, limit over-rotation, and lift safely on uneven terrain.
