Load-Engaging Elements TRIZ Cases

Clamping arms and a rotator enable safe barrier movement without manual chaining or worker exposure.

Energy-generating modules power identification tags on crane components to enable continuous data transmission.

Offset reference markings on the safety load hook align side-by-side when the mouth widens, enabling rapid visual inspection without measuring devices.

A hook and loop fastener enclosure secures a protective sleeve around wire ropes to eliminate metal-to-metal contact.

A lifting tool uses an eccentric shaft and biased pin to secure objects within a gripping cavity.

Hydraulic pressure and position sensors detect counterweight mass automatically, eliminating manual operator input errors.

Scissor arms drive beveled jaw teeth to automatically insert and bite formwork panels, preventing tool deformation and worker injury.

Pivotable gripper members on a support frame manipulate foldable pallet collars without precise positioning.

Inverted frame structures attach to the underside of a truss bridge, lowering the suspension point height to enable smaller cranes.

Internal hose routing within a segmented cardan joint structure protects hydraulic lines from external damage while maintaining accessible service points.

Integrated lifting and swivelling device manages rotor web orientation via axial displacement and pivoting arm mechanisms.

Color-coded delineation markings on a flexible sling enable precise load centering, reducing hoisting safety risks from unbalanced weights.

A connecting element integrates strain sensors to measure suspended loads while maintaining standard DIN 15412 geometry.

Convex bearing walls and concave counter-walls allow tilting freedom for the pivot pin, reducing wear during container handling operations.

A crane control unit calculates commands in Cartesian coordinates to decouple vertical and horizontal movements.

Display section indicates changed adjustment items to reduce operator omissions and errors during machine maintenance.

A hose lifter valve uses a spring to hold the closing element open, allowing external air inflow.

A cylindrical part sizing method using controlled thermal contraction to achieve precise dimensions during tempering.

A lift device with a pivot pin and locking pin secures heavy power cylinder heads for maintenance.

Internal trigger mechanism activates hook latch directly, eliminating external activation requirements and improving operational efficiency.

A spreader bar uses friction locking cable couplings to secure loads via static friction on curved engagement surfaces.

Hydraulic locking eliminates mechanical play in load bearers, preventing collision damage and reducing stress on working machines.
