A velocity control device for controlling the velocity of a load on a flexible tension member. The device can include a chassis having a chassis peripheral surface, with a portion of the chassis peripheral surface defining an exit aperture. The device can also include a capstan, the capstan having a proximal face joined to the chassis and a distal face separated at a distance from the proximal face. A peripheral capstan surface can be tapered from a greatest diameter near the distal face to a smallest diameter near the proximal face. The device can include a throttle, the throttle being attached to the chassis. The throttle can an interior surface defining an opening through which the tension member can pass with the interior surface being in at least partial contact with the tension member. Heat produced by kinetic energy in the flexible tension member is transferred to the throttle, and the change in system internal energy produces work in the form of a drag force on the flexible tension member.

An apparatus for controlling tension in a pulling rope that is attached to a flying, unmanned aerial device or drone may utilize a cylinder around which the rope is wound, a shaft that longitudinally passes through the cylinder, a disc brake rotor that is mounted to the shaft, a brake caliper that is mounted circumferentially at a periphery of the disc brake rotor, and a brake lever that tensions a cable that is attached to, and movable to control movement of, the brake caliper, which may be hydraulic, against surfaces the disc brake rotor. The brake lever may be hand actuated and mounted to a handlebar. A frame may be part of the apparatus and support apparatus components and may have a protruding hitch portion that inserts into a vehicle's receiver hitch. An adjustable pulling rope guide support through which the rope is threaded, mounts to the frame.

Well servicing surface equipment and processes for making and using same. In some examples, the well servicing can include placing a winch module adjacent to a wellhead of the well such that a cable of the winch module is extendable into the well. A power module can be placed adjacent to the wellhead of the well. The power module can be configured to provide power to the winch module. A workstation can be deployed from a first configuration to a second configuration. The workstation can include a control panel and the control panel can be physically inaccessible by an operator when in the first configuration, and the control panel can be physically accessible by the operator when in the second configuration.

A power winch horizontal-push winch, and that the power winch includes a clutch, and an operating handle is turned to move transversely to push a clutch lever through a binding groove to apply or not to apply a force to an insert slot to transmit or not to transmit the power to the cable wheel. The operating handle can change the installation angle or remove/replace the operating handle anytime. The operating handle has a penetrating hole near an outer side for receiving an end hook of a rod-shaped object, and the operating handle may be linked to turn transversely by applying a force to the rod-shaped object.

Disclosed is a winch control arrangement, including a retaining device for a cable, a rotatable drum having a rotational axis, and a substantially circular, centric storage part with a storage surface containing at least two windings of cable. The distance of the storage surface to the rotational axis is substantially constant. An eccentric holding part with a holding surface contains at least two cable windings. The distance of the holding surface to the rotational axis varies around the circumference of the holding part. A cable guide lies at a perpendicular distance from the rotational axis and the drum itself, and is movable substantially parallel to the rotational axis between a first position allowing cable winding on the centric storage part and a second position allowing cable winding on the eccentric part. The cable guide is connected to automatic movement unit for moving the cable guide between the two positions.

The present invention is a load transfer device and method of use comprising a pulley system attached to a universal pipe mount with a rope retention device. The load transfer device of the present invention allows for the maneuvering of appurtenances, such as antennas or other equipment from a load line rigged to a the main structure of a vertical infrastructure installation, to a desired installation location, such as on a standoff mount. The load transfer device helps to suspend the equipment or antenna in place above the desired installation location, enabling operators to use both hands to install the appurtenance.
