Corghi Service PRO124 Swing Arm Tire Changer
The number that defines the PRO124 is 49" (1,245mm) — its maximum wheel diameter. That is a large envelope for a swing-arm machine, and it is paired with a tire width band of 3-13" (76-330 mm), which is deliberately moderate. Read together, those two figures describe exactly the fitment that has taken over modern vehicles: big rims, short sidewalls, not especially wide. A semi-automatic machine that reaches 49" gives a shop headroom for wheels that are still growing, without paying for the width capacity of a truck-tire changer it will never use.
What the swing arm buys you
The swing arm lets the top head slide out of the way rather than staying parked over the wheel. The practical benefit is access — a technician mounting or demounting a stiff bead can work from a natural position instead of around a fixed post — and the secondary benefit is fewer accidental contacts between the tool head and the rim while the assembly is being positioned or unclamped.
It also keeps the bead breaker axis in line with the rim centre. That alignment is what stops the bead-breaking force from being applied at an angle, which is the mechanism by which beads get torn rather than released. On low-profile tires, reinforced sidewalls and run-flats — the fitments that resist hardest — the direction the force arrives from matters as much as how much of it there is.
The bead breaker
Bead-breaking power at the blade is 15000 N, and the bead-breaker opening is 13" (330mm). Those two numbers work as a pair. Force alone is not enough if the opening will not accept the assembly, and a generous opening is no use behind a weak blade. On a tire that has been seated on the same rim through several seasons and has effectively bonded itself to the bead seat, the combination is what turns a fifteen-minute struggle into a single pass.
Noise level running is quoted at under 70 dB. In a small bay, or one adjoining a customer waiting area, that is a genuine working-conditions specification and not a footnote.
Semi-automatic, and honest about it
The PRO124 is a semi-automatic machine. That is a real distinction from a fully automatic changer and worth being direct about: the operator remains part of the cycle rather than supervising it. For most independent shops that is the correct trade — fewer systems to go wrong, a lower purchase price, and a machine that a competent technician controls directly. For a very high-volume tire operation where cycle time governs revenue, a fully automatic machine will pay for itself and this one will not. Chuck rotation speed is a single 6.5 RPM, which is a controlled pace suited to alloy rims rather than a race.
Will It Fit?
Maximum dimensions are 41.34" H x 45.28" L x 36.22" D. Net weight is 527 lbs (239 kg) and gross weight is 593 lbs (269 kg); the gross figure governs your delivery planning and the net figure your floor.
The power unit is listed as 115V / 60 Hz / 1 PH and motor power at 1.1 kW, which the manufacturer's description states as about 1.47 hp. Working air pressure is 8 - 10 Bar (116 to 145 psi). Before ordering, confirm two things about your own building — both your responsibility, and both cheaper to check now than after a 593 lb crate is on your floor. First, that your compressor holds the working pressure at the machine's inlet under load rather than just at the tank. Second, that a dedicated single-phase circuit reaches where the machine will stand. Allow swing clearance for the arm as well as clearance around the cabinet.
Capacity
Inside clamping capacity is 13-26" (330-660 mm), where the jaws expand inside the rim barrel to reach the larger diameters. Outside clamping capacity is 11 inches to 24 inches (279-610 mm), gripping the outer edge of the rim, which is the everyday method for most passenger and light truck wheels. Maximum wheel diameter is 49" (1,245mm) and tire width runs 3-13" (76-330 mm). If your work sits at the wide end rather than the large-diameter end, that width band is the figure to check against a real assembly before you buy.
Perfect For
-
Independent shops whose customers are arriving on progressively larger wheels.
-
Tire specialists handling low-profile and run-flat fitments where bead-breaker geometry decides the outcome.
-
Workshops adding tire service to general repair, where semi-automatic is the right level of machine.
-
Fleet and municipal shops on a mainstream light-vehicle size range.
What's in the Box
The product data describes the swing arm and top head, the blade bead breaker and the pneumatic system as part of the machine. It does not itemise cones, adapters, protective inserts or a helper arm, so if a specific accessory is part of your plan, ask us to confirm what actually ships before you order rather than inferring it from the feature list.

Certification, stated plainly
Nothing in this machine's data claims a certification, an approval or a third-party listing, and this page does not name one. We are stating that rather than leaving it to inference, because a well-written page is very good at implying credentials it never mentioned. It does not mean no approval exists — only that none is documented with us. If an insurer, a fleet policy or a local rule requires documented approval for workshop equipment, ask us to request the manufacturer's paperwork before you commit, and confirm the requirement with whoever imposes it.
Shipping and Delivery
The PRO124 ships by freight to the lower 48 states at a gross weight of 593 lbs (269 kg), with the cost quoted live at checkout for your address. Work out the unloading before delivery day: a forklift or loading dock is the straightforward answer, and collecting from the carrier's terminal is a practical alternative if you have neither. Residential delivery addresses carry a residential fee, disclosed at checkout. Inspect the crate before you sign anything and note damage on the bill of lading while the driver is still on site — a clean signature is very hard to walk back.
Warranty
No warranty term is published in this listing, and we have not filled the gap with a guess. Ask and we will confirm the manufacturer's coverage for this model in writing before you order; the store's process is described on our warranty claims page. Whatever that term is, the same rule applies as on every machine we sell: do not take a failed component apart before the claim is open. Photograph it, contact us, and leave the assembly as it is.
