PRODUCT IDENTIFICATION & WLL RATINGS
Identification Markings
Each HOLD FAST rigging device contains a product identification number located on the back of each rigging plate. It is a multiple-digit number indicating the year of manufacture and corresponding unit number (e.g., 23001). Use this number when communicating with the manufacturer regarding your product.
Working Load Limit (WLL) Ratings
The HOLD FAST rigging device must always be used with the correct diameter of rope. You must never exceed the recommended maximum rope diameters. Each device component has a Working Load Limit (WLL) — the maximum load allowed to be applied to the device either for lifting via self-tailing winch or lowering on the fixed bollard. These values are based on a static vertical load applied as specified in these instructions.
NOTE Dynamic loads can multiply the forces in a rigging system. A dynamic load weighing considerably less than the WLL can still exceed the limit due to forces caused by its drop into the system. ALL potential loads — static and dynamic — should be carefully calculated and dynamic loads minimized where possible.
Each device is fitted with a max rope diameter and WLL capacity label as shown below:
| Model / Component | Max Rope Diameter | Working Load Limit (WLL) |
| HOLD FAST OG — Bollard | 9/16″ | 2,000 lbs |
| HOLD FAST XL — Bollard | 5/8″ | 2,500 lbs |
| Harken Radial 20 ST Winch (OG) | 1/2″ | 950 lbs |
| Harken Radial 40 ST Winch (XL) | 1/2″ | 1,500 lbs |
WARNING
You must ascertain that the device chosen is appropriate to the work being undertaken. The WLL is based on using a sufficiently rated anchor sling attached to the designated anchor point(s). The anchor sling is the primary load-bearing attachment. The ratchet strap is designed for vertical positioning ONLY and should NEVER be used alone as a mounting strategy.

The maximum working load (MWL) for the 20 ST Radial Winch is 1213 lbs. (550 Kg), and the (MWL) for the 40 ST Radial Winch is 1874 lbs. (850 Kg). Subjecting the winch to loads above the WLL can cause the winch to fail suddenly and unexpectedly during high-load events, causing severe injury or death.
Compatible Winch Line Diameters
Harken Radial self-tailing winches have jaws preloaded with springs that adapt automatically to the following line diameters:
| Minimum Rope Diameter | Maximum Rope Diameter |
| 6 mm (1/4″) | 12.7 mm (1/2″) |
WARNING
Use only line of a diameter between the limits listed above. DO NOT use wire rope, chain, or line not approved for arboriculture/marine use. To avoid accidents, carefully read, understand, and follow all warnings and instructions in the Harken Catalogue at www.harken.com.
Winch Precautions, Cleaning & Lubrication
Operating Precautions ⚠ WARNING Using the winch demands important precautions: Do not use Harken winches if you are not sufficiently trained and experienced in the general use of self-tailing winches.
- Keep your fingers, hands, loose clothing, gloves, and tools away from moving parts. In particular, avoid them entering between the line and the winch.
- Before using the winch, ensure all people and objects are clear of the movement of the reacting components of the system.
- Take particular care when releasing the line under load.
- If the winch is not in use, remove the handle and place it in a safe location outside the work zone.
- Do not apply a load greater than the maximum working load of the winch.
- Winches must be visually inspected at the beginning and end of each use.
- Winches must be completely overhauled, cleaned, and lubricated at least every 6 months. After inspection, replace any worn or damaged components. Refer to the Harken Radial Winch Maintenance Manual.
- WARNING! Periodic maintenance must be carried out on a regular basis. Lack of adequate maintenance shortens the life of the winch.
Basic Cleaning Instructions
For assembly and disassembly, refer to the Harken Radial Winch Maintenance Manual.
- Wash winches frequently with fresh water, always after each use.
- WARNING! Use a soft cloth for all cleaning and polishing operations. Do not use abrasive cloths on any component.
- Clean the bronze components and the anodized aluminum drums with a solution of water and vinegar (1 part vinegar + 2 parts water).
- Ensure the holes and drainage channels in the base of the winch are not obstructed so that water and debris does not collect.
Basic Inspection & Lubrication
For assembly and disassembly, refer to the Harken Radial Winch Maintenance Manual.
- Once the winch is completely disassembled, clean the parts with a degreasing agent that does not leave residues and is appropriate for metal components. Rinse plastic parts in fresh water.
- Dry all parts with lint-free cloths.
- Inspect gears, bearings, pins, and pawls for any signs of wear or corrosion.
- Carefully check the teeth of gears and ring gears to ensure there are no traces of wear.
- Check roller bearings to ensure there are no breaks in the bearing cages.
- Use a brush to lightly lubricate all gears, gear pins, teeth, and all moving parts with grease. Lightly lubricate pawls and springs with oil only. DO NOT use grease on the pawls!

STEM MOUNTING INSTRUCTIONS
WARNING The WLL is based on using a sufficiently rated anchor sling attached to the designated anchor point(s). The ratchet strap is designed for vertical positioning ONLY and should NEVER be used alone as a mounting strategy.

ENSURE THE WORK AREA IS FREE AND CLEAR OF ANY OBSTACLES AND A FULL TREE RISK ASSESSMENT HAS BEEN UNDERTAKEN BEFORE MOUNTING THE HOLD FAST RIGGING SYSTEM.
- When selecting the mounting location, choose an area where there is little or no stem taper. If the tree is to be removed, this can be achieved by shaping the stem prior to mounting.
- Never mount around the base/root flare of the tree — this can result in vertical slippage when load is applied.
- Install ratchet strap around the stem of the tree (Step 1) and terminate the hooked end in anchor ports (7a, 7b). A second ratchet strap can be installed in anchor ports (8a, 8b) if desired. Ensure hooks are facing toward the tree, fed correctly through the ratchet handle. Tighten the ratchet system as snugly as possible.
- Once securely mounted, attach an appropriately rated anchor sling (Step 2) to either the Basal Anchor Port (6) for up to 9/16″ diameter line, or through the Hand Port (5) for XL, or if using a larger diameter sling.
- Ensure the sling is of sufficient length to terminate the hitch properly.
CRITICAL WARNING
NEVER USE THIS DEVICE WITHOUT THE ANCHOR SLING ATTACHED. The anchor sling is the primary load-bearing attachment for the system.
HORIZONTAL ANCHORING METHOD
The HOLD FAST rigging system is unique in that it can be rigged in the horizontal position.

ENSURE THE WORK AREA IS FREE AND CLEAR OF ANY OBSTACLES AND A FULL TREE RISK ASSESSMENT HAS BEEN UNDERTAKEN BEFORE MOUNTING THE HOLD FAST RIGGING SYSTEM.
Mounting Instructions:
- For horizontal anchoring to be successful, you must have at least 2 anchors positioned approximately 45 degrees from the Basal Anchor Port (6). This allows for a triangular force to be applied to the rigging system when brought under load.
- Run a rated sling/rigging line from an appropriately rated anchor through the Hand Port (5), under the rigging plate, up through Anchor Port (7a), across the top of the rigging plate, and down through Anchor Port (7b), again running the line behind the rigging plate to emerge out of the Hand Port (5). Terminate the end of the sling/line at the second anchor.
- Run the rigging line through the fairlead and feed line clockwise around the self-tailing winch drum.
- Rotate the winch handle counter-clockwise to tension the rigging line.
- Tension the rigging line to desired tension.
NOTE The wider your anchoring positions are in relation to the Basal Anchor Port (6),( (5) for XL), the more stable your horizontal rigging platform will be.
ROPE ROUTING INSTRUCTIONS
WARNING The following instructions demonstrate the correct routing of the working line(s) for the HOLD FAST rigging system. Never use alternative routing — this may result in injury or death.
The HOLD FAST rigging system allows for the use of multiple working lines simultaneously.
The HOLD FAST rigging device must always be used with the correct diameter of rope. You must never exceed the recommended maximum rope diameters. Each device component has a
Working Load Limit (WLL) – This is the maximum load allowed to be applied to the device
component either for lifting with the self-tailing winch or lowering on the fixed bollard. These values are based on a static vertical load being applied and used as specified in these instructions. However, a dynamic load can multiply the forces incurred on a rigging system; a dynamic load weighing considerably less than the WLL of the device can still exceed the limit due to the multiplied forces caused by its drop into the system. Therefore, ALL potential loads (static and dynamic) should be carefully calculated and dynamic loads minimized where possible.
Rope Routing to Bollard

- Ensure the working line enters beneath the rigging bollard fairlead (3a or 3b) from a vertical point directly above the device.
- If NOT utilizing the winch, the working line can enter beneath either bollard fairlead (3a or 3b).
- Pass the rope behind the rear bollard post (2b).
- Pull the rope tight and continue with further wraps between the rear (2b) and front (2a) bollard posts.
- Apply the appropriate number of wraps around the bollard (2), based on the size/weight of the load being lowered.
- To suspend/lock off a load: wrap the working line a minimum of 4 times around the bollard and finish by applying a cleat hitch on the front bollard post (2a).
WARNING
Once you are in a position to commence lowering, stand clear of the drop zone, ensuring the working line will not be obstructed by the load being lowered.
Rigging Working Zone — KEEP CLEAR
- ALWAYS keep body parts, loose clothing, and debris away from the device when in use.
- ALWAYS remain outside of the Bollard Working Zone — the zone in which all lines feed through fairleads, bollards, and winch while in operation.
- ALWAYS maintain working line load pressure on bollard posts while engaged in lowering operations. This allows the user to remain at a safe distance from the device while lowering rigged pieces.

WARNING
Position yourself, body parts, loose clothing, and loose hair OUTSIDE the Rigging Working Zone at all times. Doing so also ensures correct rope alignment, greatly reducing the chance of wraps overlapping or unspooling during lowering operations. Uncontrolled falling loads can cause extreme injury or death. Any person using this equipment should be fully trained and competent in its use before carrying out any rigging operations.
Rope Routing to Self-Tailing Winch
- Ensure the working line enters beneath the rigging bollard fairlead (3b) from a vertical point directly above the device.
- Pass the rope behind the rear bollard post (2b) and toward the winch (4) positioned below the bollard.
- Take at least 3 turns (clockwise) around the winch drum (4) in the direction the winch rotates. For high loads, take an additional turn.
- Pull rope taught. To ensure correct functioning of the self-tailing mechanism, the number of turns taken around the drum must NOT hamper the movement of the lower self-tailing jaw.

- The more turns taken around the winch drum (4), the lower the load the operator has to handle.
- DO NOT take turns around the base of the winch drum.
- Position the working line over the self-tailing arm and take another turn positioning the line in the self-tailing jaws. The jaws will automatically adjust to the size of line being used. Harken recommends 1/4″–1/2″ line for the Radial winch. Do not exceed the recommended diameter for optimal self-tailing performance.
- At this point the working line is locked off.
- Insert the winch handle into the head of the winch. Begin tensioning the working line by rotating the handle counter-clockwise.
- Take particular care while releasing the line under load!
CRITICAL WARNING
DO NOT STAND UNDER THE LOAD AT ANY TIME DURING RIGGING OPERATIONS.
Removing Line from Self-Tailing Jaws
- To remove wraps: place the palm of your hand carefully on the winch drum to maintain rope/drum pressure and carefully remove one turn at a time until the load begins to move freely on the winch drum. Be particularly mindful of keeping fingers clear of line wraps and the winch drum.
- Before lowering the load, maintain control over the load from a distance by capturing the line on the bollard. Take a half turn around the forward bollard post (2a) and position yourself outside of the Working Zone. This ensures you remain clear of pieces under load and maintains correct rope alignment on the winch drum as wraps move freely when tension is released.
WARNING
Position yourself, body parts, loose clothing, and loose hair OUTSIDE the Rigging Working Zone. Uncontrolled falling loads can cause extreme injury or death. Any person using this equipment should be fully trained and competent in its use before carrying out any rigging operations.

Rope Routing — Double Working Lines

- Ensure working lines enter beneath the rigging bollard fairleads (3a, 3b) from a vertical point directly above the device.
- Pass the line intended for the bollard through bollard fairlead (3a). Pass the line intended for the self-tailing winch through fairlead (3b).
- Pass the bollard line (Green line in diagram above) between the front and rear bollard posts — this ensures available space for the self-tailing line (Red line in diagram above) behind the rear bollard post. Continue with the Bollard Routing instructions to complete the correct routing and operation sequence.
- Pass the winch line (Red line in diagram above) behind the rear bollard post (2b). Continue with the Self-Tailing Winch Routing instructions to complete the correct routing and operation sequence.
WARNING It is important while operating multiple lines to maintain separation between the bollard working line and the self-tailing winch working line. Line isolation is especially important while the rigging system is under load. Damage to both working lines will occur if care is not taken to ensure proper line routing through the system. Before applying any load to either line ensure that both working lines are appropriately isolated in the rigging system. Damaged working lines can lead to unexpected failure of one or both load bearing lines. Uncontrolled falling loads can cause extreme injury or death.
WARNING
The user should position self, body parts, loose clothing, loose hair, etc. OUTSIDE of the Rigging Working Zone. By positioning oneself outside of this zone it also ensures correct rope alignment, greatly reducing the chance for wraps overlapping or unspooling during lowering operations contributing to the uncontrolled descent of the loan. Uncontrolled falling loads can cause extreme injury of death. Any person using this equipment should be fully trained and competent in its use before carrying out any rigging operations.
