The present invention relates to servicing a harvester discharge beater and, more particularly, to remove and install the discharge beater without disassembly inside the harvester.

A system arrangement for the drive train of lifting mechanisms, such as crane lifting mechanisms, is disclosed. The system arrangement includes at least one drive motor (1, 1′), at least one cable drum (2, 2′) connected thereto, a reduction transmission (3) arranged between the drive motor (1, 1′) and the cable drum (2, 2′), an automatic overrun shutdown freewheel (6), and at least one safety brake (4, 4′). To optimize such a drive train, at least one active motor locking assembly (5, 5′) is utilized to hold the load when the drive motor (1, 1′) is decelerated electrically to a rotary speed of zero. The active motor locking assembly is utilized instead of at least one passive operating brake.

The present disclosure belongs to the technical field of fishing operation equipment in fishery, and relates to a net hauler for a trawler. The net hauler includes two rope drums, a drum rotation shaft is disposed on each rope drum and includes a first rotation shaft and a second rotation shaft, a drum is disposed on the first rotation shaft, a cylindrical housing is disposed between two ends of the first rotation shaft and the second rotation shaft, a pivot is disposed on the cylindrical housing. The present disclosure has advantages of changing a net hauling speed and improving a fishing efficiency.

A portable hoist and a winch. The winch and hoist can be integrated in a single housing or can be attached to one another. The portable hoist provides a user with the ability to hang the portable hoist without the use of other lifting devices, cranes, or rigging and allows the user to do it in a safer manner with less man power. The portable hoist can have a safety pin configured to secure the winch hook in a secured position so as to allow the hoist to lift increased loads.

Pool protection systems are disclosed. In one particular embodiment, a pool protection system may include a platform fitted in a pool, oriented substantially parallel to a surface of water in the pool, and configured to move vertically in the pool; one or more motors mechanically connected to the platform; and a controller in communication with the one or more motors.

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.
