    摘要: An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. A tracking module tracks an actual amount of line let out from the drum. A servo control unit receives the actual amount, compares the actual amount to a desired amount of line to let out from the drum, and generates an error signal reflecting a difference between the actual amount and the desired amount. A modulation module generates, from the error signal, a control signal to control the motor, thereby bringing the actual amount into better alignment with the desired amount.

    摘要: A system includes multiple lifting devices, where each lifting device includes a drum to draw in or let out a line, and a motor and transmission coupled to the drum to apply a torque thereto. A grouping module is provided to group the lifting devices for synchronized operation. A synchronization module monitors an amount of line that is drawn in or let out from each of the lifting devices and, based on the amount, adjusts operating parameters (e.g., position, speed, etc.) of one or more of the lifting devices in the group to substantially synchronize the amount of line drawn in or let out with other lifting devices in the group.

    摘要: An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. An encoder is provided to measure an angular position of the drum. A counter is provided to record a number of rotations of the drum. A locking mechanism automatically prevents rotation of the drum when the drum stops. Using this information, a processor may calculate an amount of line let out from the drum based on the number of rotations of the drum, the angular position of the drum, and a radius of the drum. In certain embodiments, the angular position and/or number of rotations is stored in non-volatile memory so that is can be recovered in the event of a power outage or other significant event.

    摘要: An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. Logistics electronics are mounted proximate a first end of the drum and power electronics are mounted proximate a second end of the drum. In general, the logistics electronics include lower power electronics that enable data processing as well as data and commands to be communicated to the apparatus from an external location. By contrast, the power electronics may include higher power electronics needed to receive power and drive the motor.
