The Challenger 31220 safety latch is the direct replacement for the Challenger lift it came off of. This is the genuine Challenger part — same fit and same working specification as the one already on your lift. Ordering the Challenger safety latch from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.

Specifications

• Part number: 31220
• Brand: Challenger
• Type: Genuine OEM safety latch

The lock ladder is the toothed steel rail bolted inside each column that the pawl climbs and catches on. Its job is simple and absolute: give the pawl a square, full-depth tooth to rest the load on at every height. When the teeth round over, chip, or the ladder loosens on its mounts, the pawl no longer has a solid shelf to sit on — and a pawl resting on a half-worn tooth is a lift resting on nothing you'd want to trust.

Restraint gear takes abuse it never shows on the surface. It absorbs the shock every time the lift settles onto the locks, and it's exposed to the same grit, water, and dropped tools as everything else at floor level. Bent teeth, a cracked weld, or a pivot rusted stiff all mean the gear can't do its job. Because it looks like solid steel, people assume it can't wear — and then it does.

Replacing your safety latch

Replacing a lock ladder or pawl is straightforward mechanical work, but it's the one repair where getting it exactly right isn't optional — the new parts have to let the pawl seat fully into a square tooth and spring home crisply every time. Set it up, then cycle the lift and confirm every lock engages and releases cleanly. Since the locks are what hold a vehicle overhead, the full procedure is worth following start to finish. Full step-by-step: how to replace a lift lock ladder.

Find the right part for your lift

Landed here but not 100% sure it is your part? Grab the model and serial from the data plate and open our Challenger parts lookup for the visual breakdown — the manufacturer-style drawing with every item numbered so you can match yours exactly. Plate missing? our guide to finding your model number helps, and we identify lifts from photos every week if you would rather ask.

Signs the locking system needs attention

Inspect the ladder teeth directly with a flashlight. Square-topped teeth with a clean flat are good; teeth that are rounded, peened over, or chipped can't give the pawl a solid shelf and let it skip under load. Compare the teeth to a fresh ladder if you can — the difference between a sharp tooth and a rounded one is exactly the difference between holding and slipping.

Parts commonly replaced at the same time

While you are in the locking system, handle the companions: the pawl, its spring, the latch, and the release cable that operates them. Replacing one worn piece and leaving the rest just means uneven locking and another visit. Give us your lift's model and we will build the matched set for both sides.

Safety notes

A lift is only as safe as its locks, and locks are mechanical parts that wear — rounded teeth, tired springs, cables out of adjustment. Replace them at the first sign of uneven or hesitant engagement, verify both sides catch and release in sync, and never park a load on locks you have not tested.

Before you order

Do the lock job once and completely: confirm model and serial, order latch, pawl, spring, and release cable together, and do both columns if either is worn. Even, synchronized locking depends on matched hardware. Call and we will confirm the right kit for your lift before it ships.

Ordering the right revision

Before this goes in the cart, grab two things off your lift: the model number and the serial number, both on the manufacturer's plate. The serial matters more than most people expect — lift makers revise components between production runs without renaming the lift, and the run your serial falls in determines which revision of this part is correct.

If you are working from a failed part rather than a plate, measure what you have and photograph how it mounts. Send that to us along with the lift brand, and we will check it against the same parts breakdowns our own techs use in the field before you commit to the order.
