Corghi ET88 Heavy-Duty Laserline Wheel Balancer w/Lift Corghi ET88 Laserline Wheel Balancer with Lift The reason to buy the ET88 over a bare balancer is on the front of the machine: an integrated pneumatic scissor lift rated to 485 lbs (220 kg). A truck wheel goes from the floor onto the shaft without a second pair of hands, without a separate wheel dolly, and without the lift-and-twist movement that ends careers. If your shop balances truck and light-truck assemblies with any regularity, that single number is the specification to compare against everything else you are looking at. Around the lift sits a laser-guided, inverter-driven balancer that detects wheel size automatically and reads out on a 19 inch widescreen monitor. It is built for shops that run cars and trucks through the same bay - which is exactly the mix that usually forces a compromise between a car machine that cannot take the weight and a truck machine that is slow on everything else. Two spin speeds, because a truck wheel is not a big car wheel The ET88 spins car wheels at 100 rpm and truck wheels at 80 rpm. The point is not speed for its own sake. Measurement accuracy on a spinning mass depends on the wheel being stable through the read, and a heavy truck assembly behaves differently on the shaft than a car wheel does. Matching the spin speed to the class of wheel is how the machine keeps the reading trustworthy across both, instead of being tuned for one and tolerable on the other. Measuring time follows the same split: our data gives roughly 6 seconds for a car wheel and 18 seconds for a truck wheel. Automatic detection of rim diameter and width removes the manual data entry that used to sit in front of every one of those cycles, and the laser positioning system shows where the weight goes rather than leaving the technician to transfer a clock position by eye. Will It Fit? The ET88 runs on 115 V, single phase, so it does not need a three-phase supply, and it needs shop air for the lift. Running noise is published as under 70 dB, which is worth knowing if the balancer lives near a waiting area or a service desk. The balancing shaft is 1.8 inches (46 mm) in diameter - check that against the cones and adaptors you already own before you assume they carry over. We do not publish a machine weight for the ET88, and here is why. Our specification table gives it as 255 kg alongside a second, unexplained figure; a separate product field says 485 lbs. But 485 lbs is also the maximum wheel weight this machine's lift is rated for, which strongly suggests that field is a copy of the wrong number. Rather than pick one, we will get it confirmed - ask us before you order if the weight affects how you plan to move or site the machine. Verifying your floor, your air supply and your electrical supply remains the customer's responsibility. The wheel range, and one figure to ask us about Rim diameter is detected automatically from 7 inches to 30 inches (762 mm). Rim width capacity is 1.5 to 22 inches (559 mm) for car wheels and 4 inches to 22 inches for truck wheels, and the machine takes wheels up to 42 inches in overall diameter. Maximum wheel weight is 485 lbs (220 kg) on both the car and truck parameter sets. One published figure does not sit with the others. The written description supplied with this product states that the maximum wheel width supported is 29 inches with the protective guard in place, while the specification tables give the rim width capacity as 22 inches. Those describe different things - a rim width and an overall assembly width are not the same measurement - but our data does not say so explicitly, and we are not going to reconcile them on your behalf. If you are buying this machine for unusually wide assemblies, ask us and we will get the manufacturer's answer in writing before you order. Programs that deal with wheels you cannot put a weight on Modern wheel designs frequently leave nowhere obvious to place a weight, and that is where balancers stop being interchangeable. The ET88 carries a hidden weight program for placing weights behind spokes where they cannot be seen, and a shift plane program for moving a correction between planes. Readout accuracy is published to a single gram, and the automatic sensor removes the manual entry step from the front of every cycle. Standby mode drops power draw when the machine is idle, which on a machine that sits between jobs for much of the day is not a trivial line item. Perfect For Mixed car and truck bays - one machine that does both properly rather than one that tolerates the other. Fleet and commercial shops where truck assemblies are handled daily and manual lifting is the real risk. Tire shops with modern alloy work, where hidden-weight placement is a routine requirement. Single-technician bays - the integrated lift is what makes that possible with heavy assemblies. What's in the Box Our data lists as part of the machine: the 19 inch LCD widescreen monitor, the integrated pneumatic lift, the automatic sensor, the shift plane program and the hidden weight program. Cones, adaptors and any truck-specific mounting hardware are not named in our record, and on a balancer that matters more than on most machines - the mounting kit determines what you can actually balance on day one.

That is an absence in our data, not a conclusion that no approval exists - the manufacturer may hold paperwork we have never been sent. We are not willing to imply a listing we cannot show you. If your insurer or a workplace inspector requires a particular document for shop equipment with a powered lift, name it before you order and we will get a written answer from the manufacturer rather than have the question arise during an inspection. Shipping and delivery The ET88 ships as freight to the lower 48 states, with the cost quoted live at checkout so it is current rather than estimated. You need to be able to take it off the truck - a dock, a forklift, or a terminal pickup arranged with the carrier. Residential delivery carries an additional fee, which checkout shows before you pay. Inspect the crate before signing the driver's paperwork and record any damage on the bill of lading at that moment. On a machine with a laser positioning system and an integrated lift, a hard knock in transit is not always visible from outside the packaging. Warranty Warranty terms are not stated in our data for this machine, so we are not going to summarise them. Our warranty claims page explains how a claim is opened with us, and we will confirm the manufacturer's current terms in writing if you ask before ordering. Whatever those terms are: do not disassemble the machine before the claim is filed. On a balancer, opening the measuring head or the lift assembly to investigate is a reliable way to lose both the warranty and the factory calibration. Photograph the fault, contact us, and let the claim start first. Contact us for more information.
