Another embodiment provides a load-bearing leadscrew without an additional support, instead having a direct connection between guide and leadscrew.

Abstract: A method for limiting the speed of a hoist mounted to a mobile well service rig involves determining a safe speed limit that ensures the hoist's capable stopping time is less than the maximum allowed time for stopping. In some examples, the maximum allowed time for stopping is based on the wellstring's modulus of elasticity and independent of the hoist's braking characteristics. The capable stopping time, however, is independent of the wellstring's modulus of elasticity and dependent on the hoist's braking characteristics.

After the power winch and two cross plates are assembled to form a basic assembly, a rope outlet board and an electric control box are assembled with the basic assembly to form the power winch in a horizontal assembly mode or an upright assembly mode, and these two assembly modes can be switched quickly to achieve the effects of reducing the manufacturing cost, improving the convenience of assembling, and broadening the scope of application.

Abstract: An apparatus and system for improving rope, strap, tie downs, hooks, and nets is provided. Includes a new design whereby the apparatus has a thick walled body made of nylon, aluminum, or stainless steel with a spool and center hub and axle throughout the spool body frame and handle. The apparatus uses multiple coils to automatically retract strap or rope within the spool hub. It also contains a tangential rib opposing the face wheel. The apparatus may have gears on the radius of the wheel, spring loaded slidable pawl plates, or pivotally rotatable pawls or plates which allow the proper engagement of the wheel ratchet. It may also have rope, strap, or belt that is non-cuttable and corrosion, petrol, and chemical resistant used in tie downs and nets. The apparatus may have a lockable body frame, and/or hooks that are lockable to prevent theft.

Abstract: A release wrench for a tie down ratchet strap, having an elongated body with a first wrench end positioned at a first end of the elongated body, and a second wrench end positioned at a second end of the elongated body. Each of the first and second wrench ends are notched such that either end can be inserted into the rotating ratchet of a tie down ratchet strap such that rotation of the release wrench causes the rotating ratchet to move. The first wrench end extends in a direction perpendicular to the elongated body of the release wrench, and the second wrench end extends in a direction parallel to the elongated body of the release wrench. As a result, the wrench can be positioned at four different (i.e.: 90 degrees apart) positions when the release wrench is first turned to cause the rotating tie down ratchet to move. This provides a simple and effective way to “un-stick” a dirty ratchet by prying it loose.
