Cranes TRIZ Cases

Integrating two knucklebooms on a single platform allows one operator to manage both, eliminating redundant machinery and reducing resource waste.

Aligning gantry legs with the boom attachment coincides opposing horizontal forces, reducing net load on the upperstructure and minimizing structural mass.

A mobile crane uses an adjustable ballast mounting apparatus coupled to the superstructure at variable radial distances.

Swiveling counterweight stacks on a mobile crane base plate adjust ballast radius, enabling 360-degree superstructure rotation within a small footprint.

Foldable accordion lattice webs collapse crane boom segments for compact transport, resolving the trade-off between structural strength and container fitment.

A lifting arm mechanism moves a crane counterweight along horizontal and vertical axes to clear structural interference.

Boom raising assist structure uses hydraulic cylinders to support boom weight, preventing tipping during setup without increasing structural capacity.

A universal installation base merges horizontal and vertical engagement seats into one unit, eliminating the need for multiple dedicated bases.

A telescopic auxiliary crane adjusts derrick ballast radius to eliminate specialized ballast wagons and reduce setup complexity.

Multi-directional pin sockets absorb positional deviations from jib deflection, enabling reliable insertion of fixing pins into boom sockets.

A variably adjustable sail unit on a crane jib captures wind energy to generate rotational torque.
