The New Harken Industrial Wingman

Written By: Lance Piatt

The Harkin Wingman is a compact haul kit that offers versatility, functioning as either a four-to-one or a five-to-one kit depending on how you position the load.

You’ll notice significant distinctions when comparing the Wingman to other mini haul kits available on the market, with one notable feature being its exceptional compactness.

We’ve engineered this design so that both blocks snugly nest within the control handle. This allows for a seamless transition to a full block-to-block setup, minimizing any potential overhead interference.

The Wingman introduces a highly unique feature not found in its predecessors. Its progress capture mechanism utilizes an eccentric cam, similar to most descent devices, but we’ve integrated it into the adaptability of a mini haul system. This means that when releasing or paying out loads, a handle snaps back into place, instantly securing the rope’s progress. One of the most significant distinctions with the release handle, akin to controlled descenders, is the ability to release a fully loaded device without the need to re-tension the system, unlike tooth cams or Prusiks commonly used in such systems.

The Wingman is equipped with two swivel eyes, positioned at both the top and bottom, ensuring effortless alignment with the correct load path as the device adjusts accordingly. Notably, the swivel eye design on the Wingman stands out from the typical market offerings.

“We’ve integrated a feature we refer to as the ‘mushroom head attachment. This design includes a robust stud that eliminates the need for roll pins, set screws, or the use of fastener-locking methods. Our approach to maintaining superior strength involves splitting the swivel’s body and subsequently rejoining it as a unified component.”

It comes equipped with fifty feet of custom cordage from Sterling Rope, specifically designed for the Wingman to minimize stretch, ensure flexibility in the smaller shiv bend radius, and provide a comfortable grip for the user.

This design prevents system overloading with an engineered slit, allowing the device to slip at four kilonewtons, which is the working load capacity of the device. This ensures that neither the rope nor the hardware is damaged, providing a safety margin of roughly six hundred and eighty pounds before any slipping occurs. As a result, users can confidently operate within a two-person low-range or single-person positioning range without any concerns.

The minimum breaking strength of this product surpasses many others currently available on the market, boasting a stated 45-kilonewton MBS (Minimum Breaking Strength). This places it firmly within the ‘G’ rating as per NFPA standards, and it holds certifications from CE and UK CA as well.

One standout feature of the Wingman is the ability of its blocks to nest together while still bearing the load. This eliminates the necessity of relieving tension from the load to release a Prusik or toothed cam, streamlining its operation.


The WingMan is a mechanical-advantage device for load lifting and releasing. It is used in a fall protection or work at height system. It is intended for work at height, access, and rescue use. It can be used for human suspension for up to a 3 kN load. The WingMan consists of two swivel pulleys and a manufacturer supplied rope. One pulley is a double with a becket to dead end the rope. The other pulley is a double with a ratchet and cammed sheave with a releasing handle allowing gradual release of the mechanical advantage system under load. The releasing handle is located at the operator end. Anodized aluminum is used throughout the pulleys. The handle is glass reinforced nylon. The rope is an 8 mm static polyester with a sewn termination and is not to be substituted. Pulleys have stainless steel axles and fasteners. The ratchet mechanism is stainless steel.
