An overhead transport vehicle includes a lift stage to transfer an article, a winding drum to overlap and wind a suspension attached to the lift stage, and a controller to control a rotation amount of the winding drum to control a lifting/lowering amount of the lift stage. The controller is configured or programmed to execute a first processing including calculating, as individual values of the overhead transport vehicle, an individual value of an entire length of the suspension, an individual value of a diameter of the winding drum, and an individual value of a thickness of the suspension, and a second processing including calculating a rotation amount of the winding drum with respect to a lifting/lowering amount of the lift stage based on the individual value of the entire length of the suspension, the individual value of the diameter of the winding drum, and the individual value of the thickness of the suspension calculated in the first processing.

A winch includes a coupling A, a coupling B, a rectangular spring, a gear wheel, a gear rack, a friction ring, and a transmission shaft, etc. By increasing the distance between the adjacent internal teeth of the two-stage planet carrier, it ensures that the three-stage sun gear can be smoothly inserted into the two-stage planet carrier even if the elasticity of spring A is reduced, such that the engagement width between the three-stage sun gear and the two-stage planet carrier can reach the normal requirements. With the design of sliding gear ring and spring C, it can greatly reduce the phenomenon of mis-engagement when the external teeth of the three-stage sun gear enter the internal teeth spacing of the two-stage planet carrier, protect the teeth integrity of the three-stage sun gear and the two-stage planet carrier.

A double-drum linkage winding type hoisting system includes a first hoisting drum and a second hoisting drum. The first hoisting drum and the second hoisting drum are engaged and linked through engagement structures on outer circumferences of the first hoisting drum and the second hoisting drum or are linked through a linkage intermediate member. A first hoisting rope is wound around the first hoisting drum. A second hoisting rope is wound around the second hoisting drum. The first hoisting rope and the second hoisting rope are not connected with each other.

A method includes: determining a mast angle of a drilling implement, calculating the optimized hoisting speed for a drilling implement based on the mast angle or calculating the optimized drill rotation speed based on the mast angle, and hoisting the drilling implement at the optimized hoisting speed if desired, or rotating the drill at the optimized drill rotation speed if desired.

The present disclosure discloses a vehicle, a winch for the vehicle, and a warning control device for the winch of the vehicle. The warning control device includes: a warning component; and a warning control board, including: a load detector, connected to the motor through a current sensor, and configured to detect load condition of the motor by collecting measured working current of the motor; a processor, connected to the load detector and the warning controller respectively, and configured to output a warning control signal to the warning controller according to the load condition of the motor; and a warning controller, connected to the warning component and the processor respectively, and configured to receive the warning control signal and to control the warning component to produce a warning based on the warning control signal.

Methods and apparatus for anchoring a boat are described. Novel methods provide means for sensing and measuring the real time rate and length of rode release based on detecting real time changes in the angular position of a windlass by computer vision using a portable computing device. Rode release is also detected using novel methods based on sensing sound, rode chain movement, and sensing acceleration and/or motion. The apparatus can include software operable to provide safe anchoring based on monitoring real times values of the rate and length of rode release, comparing these values to the speed and position of the boat, and providing local and remote status and alarm information to crew members.
