Challenger 20,000 lb Symmetric 2-Post Lift #CL20-2

Challenger 20,000 lb Symmetric 2-Post Lift #CL20-2

A tall-body medium-duty truck on a standard-height lift is stuck: the truck is on the arms, but the body never gets to a comfortable working height, and the shop pays for 20,000 lbs of capacity it cannot fully use. The CL20-2 is the 2 ft. extension answer: 198 in. of column height on the same 20,000 lb symmetric two-post platform.

It keeps the 2-stage front and rear arms, single-point air lock release, and 5,000 lbs per-arm rating of the CL20, adding the column height tall-body trucks need to clear work height in shops that have the ceiling for it.

Who the CL20-2 Is Built For

• Truck shops servicing walk-in and box bodies — the 198 in. columns bring a tall body to real working height, where standard 174 in. columns leave it hanging too low to work under.
• Fleet yards with about 16 ft of clear ceiling — the extended columns convert height the shop already has into service access it currently does not have.
• Municipal fleets with medium-duty trucks at or near 20,000 lbs — the 5,000 lb per-arm rating carries them at rating without stacking adapters.
• High-cycle shops — the air-actuated single-point lock release releases both columns at once on 90 - 120 psi shop air, cycle after cycle.
• Shops that measured the ceiling and found 15'8" or more — exactly the clearance the CL20-2 was built to use, instead of sending that work to a shop with a taller lift.

What the CL20-2 Is NOT Built For

This is not the right choice when your ceiling cannot support 15'8" or more of clearance, your trucks fit the standard 174 in. column height, or your vehicle weights exceed 20,000 lbs. If you are close on any spec, compare it with Challenger 20,000 lb Symmetric 2-Post Lift #CL20 or call Alamo.

Important sizing note: The CL20-2 publishes 20,000 lbs capacity, 198 in. column height with 2 ft. extensions, and 154.75" - 166.75" installed width options. Measure the bay and confirm the exact vehicle mix before purchase.

What Makes the CL20-2 Different

2 Ft. Column Extensions

The extensions take the CL20-2 to 198 in. of column height — the working difference for tall-body trucks, where the standard 174 in. columns leave the raised body hanging below comfortable service height. Challenger lists matching ceiling requirements of 15'8" - 16'8" across the extended column settings.

20,000 lb Symmetric Capacity

The symmetric configuration carries 20,000 lbs at 5,000 lbs per arm, sized for medium-duty trucks rather than stretched passenger-car geometry. The 2-stage arms keep the spotting rigid at heavy per-arm loads.

• Use the published capacity and per-arm rating as the first decision filter.
• Confirm the lift points on your tallest daily trucks.
• Ask Alamo to compare the standard CL20 if your ceiling is the constraint.
• Keep the install team involved before the bay is committed.

Single-Point Air-Actuated Lock Release

One air-actuated control releases both column locks simultaneously on 90 - 120 psi shop air — fast cycles on a truck bay, with no walking between columns at the end of every service.

Bay Planning Numbers

The key measurements are a 15'8" - 16'8" ceiling requirement (by column setting), 154.75" - 166.75" installed width options, and 104.25" - 116.25" drive-through clearance. Tall columns make the overhead check the one that ends installations early — measure it first.

Electrical and Install Coordination

The published electrical line is 3HP, 208/230v, 1 Phase, 60Hz. Have a licensed electrician confirm the circuit and final local requirements before installation day.

Service After the Sale

Alamo installs and services the lifts we sell, so the same team that helps size the CL20-2 can support the equipment after it is in the bay.

Best For

• Tall-body trucks within the 20,000 lbs rating
• Bays with 15'8" - 16'8" verified ceiling clearance
• Shops that want fast lock-release cycles via shop air
• Buyers who want Alamo installation and service support

Not Ideal For

• Bays that cannot clear the extended column height
• Standard-body trucks that fit the CL20's 174 in. columns
• Vehicles above the rated capacity
• Shops without 90 - 120 psi shop air

Challenger Lifts Warranty - CL20-2

Challenger Lifts backs the CL20 series with manufacturer warranty coverage. Challenger's published warranty schedule does not list a model-specific row for the CL20-2, so Alamo confirms the exact current terms in writing at purchase rather than quoting an unverified number here.

Warranty service is coordinated through Alamo Equipment & Service — call (817) 865-3707 and we help get the issue moving.

Warranty terms can change. Confirm exact coverage at the time of purchase. Warranty can be void if the lift is installed improperly or not anchored per spec.
