Safe come along tool use requires horizontal pulling only, proper PPE, and a firm anchor — most models are not rated for lifting people or overhead loads.
One wrong move with a come along turns a straight pull into a cable snapback that can kill. The short list of hard rules about load limits, anchor points, and never standing in the line of fire — that’s come along tool safety. Most come-alongs are rated for horizontal pulling, not vertical lifting, and treating them like a chain hoist is how cables snap.
What Makes A Come Along Different From A Hoist?
A come along (also called a hand winch or cable puller) is designed to drag loads across a surface. A chain hoist lifts them vertically. The two tools look similar but serve different purposes, and mixing them up is one of the most dangerous mistakes on a job site. The IADC safety guidelines explicitly warn against using a come-along for lifting unless the manufacturer has rated it for dead lift. Most aren’t.
A dead-lift rating means the tool can hold a load suspended vertically without the cable slipping or the brake failing. A pull rating means the tool can drag that same load across the ground — which puts less peak stress on the cable and the hooks. If your come-along’s spec sheet lists only a pull rating, treat it as a pull-only tool.
Come Along Safety: The Three Rules That Matter Most
Every safe come-along operation rests on these three rules, and skipping any one of them is how a routine pull turns into a trip to the ER.
- The anchor must be stronger than the load. The anchor point — tree, trailer hitch, structural beam — needs to handle not just the load’s weight but the shock load from a sudden stop or a cable that snaps taut. A weak anchor that pulls free turns the load into a projectile.
- The pull must be straight and centered. Angular pulls multiply stress on the hook and the frame. The IADC advises checking that the load is centered before you start ratcheting. Even a 10-degree angle adds significant side-load that the tool wasn’t designed for.
- Never stand in the line of fire. If the cable snaps, it whips upward and backward with lethal force. Lay a tarp or chain over the cable to redirect a snapback into the ground, and keep everyone out of the pulling direction.
Come Along Specs That Affect Safety
The table below shows how key specifications vary across common come-along classes and why each spec matters for safe operation. For a full comparison of top-rated models across these classes, see our tested roundup of the best come along tools for different jobs.
| Specification | Light-Duty | Heavy-Duty (e.g., Hud-son 3-20-SLT) |
|---|---|---|
| Cable Diameter | 3/16″ steel cable | 5/16″ galvanized aircraft cable |
| Cable Length | 10–12 ft | 20 ft |
| Single-Line Pull Rating | 1 ton (2,000 lbs) | 3 tons (6,000 lbs) |
| Double-Line Pull Rating | 2 tons (4,000 lbs) | 6 tons (12,000 lbs) |
| Dead Lift Rating | Not rated | 3 tons (6,000 lbs) |
| Safety Factor | 2:1 | 2:1 |
| Hook Type | Drop-forged steel | Drop-forged with safety latch |
| Housing Material | Steel | Cast aluminum alloy |
The 2:1 safety factor is industry standard for cable pullers — the tool can handle twice its rated load before failure, but that margin is not a license to overload. The dead-lift rating on the heavy-duty class means it can hold a load vertically, but even then, most manufacturers recommend a chain hoist for any overhead work.
How To Use A Come Along Safely (Step By Step)
The NBCC Safe Work Practice for come-alongs outlines a repeatable 12-step sequence. The steps are simple, but each one exists because someone got hurt skipping it.
- Wear PPE: Gloves, safety glasses, and steel-toe boots are non-negotiable.
- Inspect the tool: Check the full cable length for fraying or knots. Examine hooks for cracks or deformation. Test the springs and pawls.
- Secure the anchor: Hook the swivel end to a stationary anchor that can support the load plus shock load.
- Disengage the pawl: Release the drive pawl so the ratchet can roll freely.
- Install a sling: Use a proper sling around the load — never wrap the cable or chain around the load as a sling.
- Attach the cable hook: Connect the cable hook to the sling ends.
- Engage the pawl: Re-engage the drive pawl so it catches the ratchet.
- Ratchet evenly: Pull the lever with smooth, forward pressure. No jerking, bouncing, or sudden releases.
- Secure the load: Once the load is where you want it, engage the safety latch.
- Disengage carefully: Adjust the drive pawl spring to release tension. Push the lever fully forward and hold it while the load transfers. Keep hands clear during this step.
- Detach and retract: Remove the hook from the sling, the sling from the load, and the swivel from the anchor. Ratchet the cable fully back into the housing.
- Store properly: Keep the come-along in a clean, dry area. Lubricate moving parts per the manufacturer’s schedule.
The IADC adds a key checkpoint at step 8: lift the load just a few inches first, stop, and check that everything is level and stable before proceeding. The IADC come-along and chain hoist safety guidelines also emphasize that you should never use cheater bars on the lever — the tool is designed for one person’s arm strength, and extending the lever with a pipe can overload and break the housing.
Common Mistakes That Get People Hurt
Most come-along injuries follow the same patterns. The table below shows what goes wrong and what to do instead.
| Mistake | Why It’s Dangerous | Safe Alternative |
|---|---|---|
| Using a cheater bar on the lever | Exceeds the tool’s designed leverage, causing the housing or cable to fail | Use a larger-capacity come-along for heavier loads |
| Lifting overhead without a dead-lift rating | The tool may not hold a suspended load; cable can slip or hooks can straighten | Use a chain hoist rated for overhead lifting |
| Angular or off-center pulls | Side-load stresses the hook and frame, reducing effective capacity | Center the load and pull straight |
| Using the cable as a sling | Kinking or fraying the cable weakens it; cable was not designed for choker or basket hitches | Use a rated sling or chain around the load |
| Two people pulling the lever | Doubles the input force but not the tool’s capacity; can overload the mechanism | Use a come-along with a higher pull rating |
| Standing in the line of fire | A snapped cable whips backward with lethal speed | Stand to the side; lay a tarp over the cable to ground a snapback |
| DIY repairs on a defective unit | Repairing a pawl or spring incorrectly can cause unexpected release under load | Tag the tool as defective and return it for professional repair |
Final Come-Along Safety Checklist
Before every pull, run through this checklist. Every item on it is tied to a real injury that someone thought wouldn’t happen to them.
- Inspected the full cable length for fraying, kinks, or corrosion
- Hooks and latches are intact and close fully
- Anchor point is rated for the load plus shock load
- Load is centered and the pull angle is straight
- No one is standing in the line of fire
- A tarp or chain is laid over the cable for snapback protection
- PPE is on: gloves, glasses, steel-toe boots
- The lever is clean and free of cheater-bar extensions
- The load has been lifted a few inches and checked for level
- The tool will be stored clean and dry after use
FAQs
Can a come along be used for vertical lifting?
Only if the manufacturer specifically rates the model for dead lift. Most come-alongs are rated for horizontal pulling only. Using a pull-rated come-along for overhead lifting risks cable failure and dropped loads. A chain hoist is the correct tool for vertical work.
What does the safety factor on a come along mean?
The safety factor is the multiple of the rated load the tool can withstand before failure. That margin accounts for wear and shock loads, but it is not a cushion for exceeding the rated capacity during normal use.
How often should a come along be inspected?
Inspect the come-along before every use — check the cable for fraying, hooks for cracks, and the pawl mechanism for smooth operation. A formal inspection by a qualified technician should happen at least annually, or immediately after any incident that could have damaged the tool.
Why is a cheater bar dangerous on a come along?
A cheater bar extends the lever arm, which multiplies the force applied to the mechanism. The tool’s housing, cable, and pawls were designed for the force one person can generate with the stock lever. Adding a pipe can overload any of those components silently, and failure under load causes catastrophic snapback.
Can a come along lift a car or truck?
A come-along is ideal for dragging a vehicle across a surface — pulling a stuck truck out of mud, for example. Lifting a vehicle vertically (such as for repair work) requires a jack, jack stands, or a vehicle lift. A come-along used for vertical vehicle lifting creates an unsafe suspended load.
