Hoisting Equipments TRIZ Cases
- Hydraulic Brake Lowering Control With Accumulator Pressure Buffering
A pressurized accumulator and three-way regulator decouple pumping from brake pressure control for safer, gradual load lowering.
- Cable Winch Emergency Brake Using Threaded Drum-Driven Actuation
A drum-driven threaded actuator converts fall energy into smooth emergency braking, stopping the winch while limiting rope force spikes.
- Winch Brake Sleeve and Elastic Ring for Low-Noise Braking
An elastic ring lets the winch brake sleeve float against the rope drum, cutting friction, noise, vibration, and energy use.
