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.

A portable pulling device and method therefore, the portable pulling device including a chassis frame, a power source, anchoring elements, a spool, a rope or cable attached thereon, and a centrifugal clutch with a chain or belt drive system allowing the ability to pull out the rope when the power source is at idle. The device further contains frame propulsion components such as wheels, skis, or tracks to facilitate movement of the pulling device into and through a confined area such as a forest or a barren area.

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 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.
