Portable Lifting TRIZ Cases
- Chain Block Gear Cover Rib Stiffness Design
Upper and lower ribs on the gear-side frame resist deformation under load, maintaining reduction gear positioning accuracy.
- Gear Drive Device With Biasing Member And Partially Removed Teeth
A gear drive device uses a biasing member to apply rotational torque for smooth mesh and reliable torque transmission.
- Portable Winch with Segmented Battery for Vehicle Recovery
Segmenting the battery from the vehicle electrical system prevents voltage drop during extended winching, maintaining reliable engine starting capability.
- Portable Pulling Device Centrifugal Clutch Drivetrain
A portable pulling device uses a centrifugal clutch to drive a spool for rope retraction.
- Rope Winch Load Sensor Exchangeable Mounting Plate
An exchangeable sensor mounting plate secures a load detection device on a rope winch bearing support structure.
- Multiplate Clutch Outer Part Groove Geometry for Ironing Resistance
Inclined groove bottoms and increasing arc radii minimize ironing resistance, preventing cracks in multiplate clutch outer parts.
- Portable Log Skidder Winch Pulley System for ATV Stability
A portable log skidder uses a winch and movable pulley to lift logs onto a bunk frame.
- Resin Gear Flow Velocity Grooves for Weld Line Prevention
Resin flow velocity regulating grooves equalize radial injection flow from pin point gates, preventing weld lines and enhancing gear strength.
- Pulley With Two-Step Rod And Shutter Locking Mechanism
A pulley uses a rod and shutter to hold the flange closed until two distinct movements unlock it.
- Industrial Vehicle Spare Tire Handling Winch and Pulley System
Adjustable threaded members and a winch cable allow one operator to lower heavy spare tires, cutting field replacement downtime.
- Rotation Lock Device for Lever Hoist Brake Failure
A rotation lock device uses centrifugal force to project a stopper member, engaging a locking mechanism to halt shaft rotation.
- Cable Return Pulley Sector Coupling for Reduced Machining
Segmented sectors couple to a hub along two straight lines, reducing machining precision needs while maintaining structural stability.
- Hoist Drum Groove Contour for Fiber Rope Wear Reduction
A hoist drum groove with a pressed-flat oval contour adapts to fiber rope deformation.
- Sliding Gate Rack Design with 180-Degree Connector
Cold-formed steel rack joins parallel flat portions via a curved connector, reducing material usage and production costs.
- Lifting Device Automatic Reeving Configuration Change
A lifting device uses a reversible mechanical connection system to automatically switch reeving configurations based on cable strand force measurements.
- X-ray Gantry Cable Break Detection System
A response assembly detects cable breaks in X-ray gantry transmission systems to trigger immediate safety signals.
- Crane Sheave Pin Removal Assembly Without Rope Unreeving
A pin removal assembly supports sheaves during pin extraction to simplify maintenance operations.
