If your body shop straightens structural damage, the frame machine is the piece of equipment that determines whether you do it right or do it twice. A frame machine that pulls accurately, measures precisely, and holds the vehicle securely is the difference between a repair that meets OEM specs and one that looks close but sends a vehicle down the road with compromised crash protection. We sell, install, repair, and calibrate frame machines across Iowa — and we work directly with Car-O-Liner, one of the most respected names in collision repair equipment worldwide.
Auto Lift Services is based in Ames, Iowa. We are a Car-O-Liner dealer sourcing equipment direct from the manufacturer, and we also carry frame machine options through the AMI catalog. We handle the full lifecycle — from helping you choose the right frame machine for your shop’s volume and vehicle mix, to pouring the right foundation, to keeping the measuring system dead-accurate years after installation. This page covers everything Iowa body shops need to know about frame machines: what they do, what we sell, what installation requires, and how we keep them running.
What a Frame Machine Does
A frame machine — also called a frame rack or frame straightener — is a platform designed to anchor a damaged vehicle and apply controlled hydraulic force to pull bent structural components back to their factory dimensions. The vehicle is secured to the rack using pinch weld clamps and fixture points. A hydraulic draw aligner, connected to chains and clamps, applies pulling force at precise angles to reverse collision damage.
The key word is “precise.” A frame machine does not just yank metal back into roughly the right shape. Modern unibody and full-frame vehicles have exact dimensional specifications from the manufacturer. Every structural reference point — every rail, every crossmember, every subframe mounting location — has a factory measurement. A quality frame machine paired with an accurate measuring system allows the technician to pull each point back to spec within millimeters.
This matters because modern vehicles are engineered to crumple in specific patterns during a collision. If a repair changes those crumple zones — even slightly — the vehicle may not protect its occupants the same way in a subsequent crash. Insurance companies, OEM certification programs, and I-CAR all require dimensional accuracy in structural repair. The frame machine in Iowa that produces that accuracy earns the shop its reputation and its certifications.
Frame Machines We Sell
Car-O-Liner
Car-O-Liner is a Swedish manufacturer that has been building collision repair equipment since 1957. Their frame racks are used by OEM-certified collision centers worldwide — the shops that manufacturers like Mercedes, BMW, Tesla, Rivian, and others have approved to perform structural repairs on their vehicles. We carry Car-O-Liner direct from the manufacturer, which means factory support, factory training access, and genuine parts.
BenchRack — The BenchRack is Car-O-Liner’s flagship drive-on frame rack. The vehicle drives directly onto the platform — no secondary lifting or loading required. The BenchRack features tilt loading for low-profile vehicles, a 10-ton draw aligner operating at 10,000 PSI hydraulic pressure, and a vehicle capacity up to 9,259 pounds. It is available in three lengths: 16 feet 5 inches, 18 feet, and 20 feet 8 inches. The longer platforms accommodate full-size trucks, SUVs, and extended-cab pickups that shorter racks cannot handle. The BenchRack is the workhorse for shops doing daily structural repair on a wide range of vehicles.
BenchRack Versa — The Versa variant adds 360-degree access for the draw aligner. On a standard BenchRack, the draw aligner works from fixed positions along the platform. The Versa allows the aligner to travel around the full perimeter of the vehicle, which means the technician can set up pulls from any angle without repositioning the vehicle or rigging awkward chain configurations. For complex hits — offset frontal, multi-point collision, heavy rear damage combined with side impact — the Versa saves significant setup time and produces cleaner pulls.
Quick42 — The Quick42 is a multi-functional alignment bench designed for shops that need frame straightening capability without dedicating a full bay to a BenchRack. It handles structural pulls with the same 10,000 PSI hydraulic system but in a more compact footprint. For shops doing moderate collision volume alongside mechanical work, the Quick42 provides frame machine capability without the full BenchRack commitment.
Speed — The Speed is a lighter-duty frame machine designed primarily for unibody passenger cars. It uses a 5-ton pulling capacity at 10,000 PSI, which is more than adequate for the structural components found in most sedans, coupes, and small crossovers. The Speed is a strong choice for shops that handle mostly car-on-car collisions and do not regularly work on full-frame trucks or heavy SUVs.
AMI Catalog Options
Beyond Car-O-Liner, we source frame machines and accessories through the AMI catalog. This gives us access to additional brands and configurations for shops with specific requirements or budget considerations. Whether you need a particular anchoring system, a replacement draw aligner, or supplementary pulling accessories, we can source it.
What to Know Before You Buy a Frame Machine
Floor Requirements
A frame machine is not a piece of equipment you roll into a bay and plug in. The platform anchors to the shop floor, and the floor has to handle the forces involved. A 10-ton draw aligner pulling against a secured vehicle generates enormous lateral and vertical loads through the anchor points. If the concrete is not thick enough, not reinforced properly, or has existing cracks, those anchors can pull loose under load — which is dangerous and makes accurate pulls impossible.
Most frame machine installations require a minimum concrete thickness of 6 inches with rebar reinforcement. Some configurations need thicker pads or additional reinforcement at the anchor points. We assess the floor before every installation and spec the concrete work if needed. Skipping this step is not an option. Read our frame machine for sale page for detailed specs on floor requirements for each model.
Power Requirements
The hydraulic power unit that drives the draw aligner needs dedicated electrical service. Most frame machines require 220-240V single-phase or three-phase power, depending on the model and the hydraulic pump configuration. The circuit needs to be properly sized for the motor’s starting current, not just its running current. We coordinate electrical requirements during the installation planning phase so there are no surprises on installation day.
Space and Bay Layout
Frame machines are long. The BenchRack in its 20-foot-8-inch configuration, plus the space needed for the draw aligner to extend and for the technician to work around the vehicle, can require a bay that is 30 feet deep or more. Width matters too — the draw aligner needs clearance to swing to pulling positions on both sides. Shops planning a frame machine installation should involve us early in the layout process, especially if they are building new or reconfiguring existing bays.
Measuring Systems
A frame machine without an accurate measuring system is a piece of metal that bends other metal. The measuring system is what tells the technician whether the pull actually restored the vehicle to OEM dimensions. Car-O-Liner’s measuring systems use electronic and laser reference points to compare the damaged vehicle’s dimensions against the factory database. If the measuring system drifts, every pull the tech makes is based on bad data — and the repair fails inspection or, worse, passes inspection but leaves the vehicle structurally compromised.
We calibrate measuring systems as part of installation and provide ongoing calibration service. More on this in our frame machine repair guide.
Our Installation Process
We handle frame machine installation from site survey to final calibration. The process typically involves:
Site survey — We visit the shop, measure the bay, assess the floor, check electrical capacity, and identify any obstructions (ceiling height, column placement, door clearances for vehicle entry).
Floor preparation — If the existing concrete does not meet spec, we coordinate the concrete work. This may mean cutting out a section and pouring a new pad, adding reinforcement, or in new construction, specifying the slab requirements to the general contractor before the pour.
Equipment delivery and positioning — Frame machines are heavy and require rigging equipment to place. We handle delivery, unloading, and positioning in the bay.
Anchoring and assembly — The platform is anchored to the floor per manufacturer specifications. The draw aligner, clamps, chains, and hydraulic system are assembled and connected.
Electrical connection — We coordinate with the shop’s electrician to ensure proper power delivery to the hydraulic unit.
Calibration and testing — The measuring system is calibrated against known references. We run test measurements to verify accuracy before the machine goes into production.
Training — We walk your techs through operation, setup procedures, and basic maintenance. Car-O-Liner also offers formal training programs for shops pursuing OEM certifications.
Frame Machine Repair and Calibration
Frame machines take abuse. The hydraulic system operates at 10,000 PSI. Chains and clamps grip damaged steel and pull against it with tons of force. Over time, hydraulic seals wear, cylinders develop leaks, chains stretch, clamp teeth dull, and measuring system references drift. A frame machine in Iowa that ran perfectly at installation can produce inaccurate repairs a year later if it has not been maintained and calibrated.
We provide repair and calibration service for frame machines across Iowa. Common service items include hydraulic cylinder rebuilds, draw aligner repair, chain and clamp replacement, measuring system recalibration, pinch weld clamp restoration, and hydraulic power unit service.
When a frame machine goes down in a busy collision shop, every structural repair stops. We understand the urgency. Our service territory covers the state, and we carry common wear parts. For the full breakdown of what we repair and when it makes sense to repair versus replace, read our frame machine repair guide.
Who Needs a Frame Machine
Frame machines are essential equipment for any shop performing structural collision repair. This includes:
OEM-certified collision centers — Every manufacturer certification program (Tesla, Rivian, BMW, Mercedes, Ford, GM, Toyota, and others) requires the shop to have frame straightening capability with approved measuring systems. Car-O-Liner equipment meets the requirements for most major OEM certification programs.
Independent collision shops — If you write structural repair on estimates, you need the equipment to do it properly. Subcontracting frame work to another shop means lost revenue and lost control over quality and turnaround.
Insurance DRP shops — Direct Repair Program shops are expected to handle structural repair in-house. Frame machine capability is a baseline requirement for most DRP agreements.
Dealership body shops — Factory-backed body shops need frame equipment that meets the brand’s certification requirements. Car-O-Liner’s OEM approvals make it a strong fit for dealership collision centers.
Multi-location collision groups — Groups like Caliber, Service King, and Gerber spec frame equipment across their networks. We can equip multiple locations with consistent equipment and standardized installation.
