Trolley Cranes TRIZ Cases

A crank-and-cable hoist stand lowers and lifts heavy food over hot oil with controlled motion, reducing splash risk and back strain.

A bent target line lets a gantry crane correct inclination through wheel-speed control, enabling faster and more precise positioning.

An elevated transfer section lets overhead and ground vehicles exchange articles without using floor space, preserving travel range in tight facilities.

Extending route busbars into the positioning area keeps the crane powered during vertical contact insertion, enabling container handling in less space.

UWB positioning, switch sensing, and LiFi links let a monorail hoist run unmanned underground while reducing operator risk.

Independent x-y motion planning enables fast lifting-path replanning for changed end points while avoiding obstacles and collisions.

Sensor-guided straddle carrier control aligns containers behind parked ones with high accuracy, improving dense stack handling and port throughput.

By moving navigation sensors outside the clearance profile, the gantry lift can read side marking elements while handling containers without height limits.

Independent X-Y motion planning enables real-time endpoint changes with lower computation and collision-free load movement.

Sensors detect the rear wall of a set-down container so a straddle carrier can align the next one with narrow spacing and higher throughput.

By moving navigation sensors outside the clearance profile, this case enables automatic gantry travel and container handling without extra lift height.

Staggered wheel heights and elastic support reduce rail-entry impact while keeping the vehicle member level during transfer.

By scanning containers on a quay crane during loading and unloading, this layout cuts inspection space needs and port circulation time.

Partial cuts at crane legs and girders enable a controlled fold-down collapse, reducing work at height, over-water risk, and heavy lifting.

A 3D ranging sensor widens lower-space coverage and helps distinguish obstacles from peripheral equipment during article transfer.

Guide rails and independent suspension points let an unmanned crane hook and unhook loads without horizontal drift in dusty, high-temperature sites.

3D lidar mounted above rectangular crane access areas removes blind spots across varying rail vehicle lengths and enables timely warnings or stops.

Schedules hydrogen supply during spare time in cargo handling operations to prevent fuel depletion and maintain handling efficiency.

Real-time state perception switches permanent magnet motors between torque and power modes to prevent wheel spin and keep monorail drives synchronized.

A switchable diesel-hydrogen power setup lets port cargo equipment cut CO2 emissions without long terminal shutdowns or trolley-line construction.

Synchronous 90° wheel rotation lets a handling vehicle reach any floor stack, improving maneuverability, storage density, and picking flow.

Angled 2D or 3D LiDAR scans the full container underside as it moves, separating unremoved twist locks from noise and deformation.

Multiple trolleys on parallel continuous tracks handle containers concurrently, reducing loading and unloading time for large vessels.
