Mobile Jacks TRIZ Cases

A hydraulic jack lever rotates to engage a stopping element within the cylinder articulation for mechanical locking.

Locking pin engages frame holes to provide mechanical stability, eliminating hydraulic dependency and external jack stands.

Spring-loaded pins lock sliders on the boom to adjust lifting height and load capacity without complex manual operations.

Battery-operated electro-hydraulic service jack eliminates tripping hazards from air lines while reducing operator physical force.

A C-shaped steel accessory converts flat hydraulic jack saddles into arched supports for secure lifting.

Dual ratchets lock the integrated assembly under unibody vehicles, stabilizing limited contact points without separate stands.

An adjustable universal adaptor stabilizes heavy automotive transmissions using vertically offset elongated arms with holding assemblies.

Foot-controlled elevator devices lift wall partitions via downward force, eliminating manual leverage risks and preventing damage to dividers or walls.

Interchangeable heads and adjustable shafts on a bottle jack provide precise lift point engagement, preventing dangerous shifting during heavy load operations.

A mobile lifting platform uses a roller adjustment device to enable lateral movement in confined workshop spaces.

Segmented cradles and extracted rotation mechanisms resolve accessibility and hydraulic leak contradictions in aircraft engine transport.

Sliding wheel engagement attachments on a hospital bed lifter accommodate various wheel configurations while preventing interference with bed pedals.

Tension springs bias the slide forward bridge mechanism to align jack stands, eliminating frequent retrieval trips that lower productivity.

Segmented actuators lift large trucks safely, eliminating operator exposure under the load.

Ratcheting dogs engage rack bars to lock lift arms during pressure loss, while a cam tube releases them when pressure restores.

Spring-operated brake plates engage shooter rods on rails to prevent uncontrolled load descent on inclines without power.

An actuator moves the wheel assembly axially to transition between ground handling mobility and vertical support, reducing setup time.

An integrated pawl support mechanism allows the floor jack to roll freely during lifting while providing stable vehicle support without separate stands.

A wheeled equipment stand uses locking caster wheels to transition between mobile and stable states for heavy loads.

A lever pivots on roller assemblies to lift a nose wheel fork for maintenance access.

A four-bar linkage transforms vertical lifting motion into an angled path, keeping the saddle horizontal while moving it away from the base for operator access.

A portable vehicle lift system uses a remote control station to operate front and rear lifting units from a safe distance.

A lift jack incorporates a slow descending device with springs and fixing protrusions to control support sheet retraction.

A detachable lift assembly integrates a motorized jack with an omnidirectional tire lift to automate vehicle elevation.

A battery-operated vehicle jack uses an electric motor to drive a lead screw mechanism for lifting loads.
