Its measuring speed is listed at under 100 rpm, roughly half the shaft speed the larger models in the range are specified for, and Hofmann still quotes the same ±0.35° angular resolution for it. That is the interesting fact about this machine: the accuracy comes out of the VPI measuring technique rather than out of shaft speed, so the 7100 does not have to work a wheel hard to know what is wrong with it.\u003c\/p\u003e \u003cp\u003eIt is the compact, LED-display balancer in the line — a machine for the smaller tire shop, the general repair bay adding wheel service, or the second balancer in a busy shop that needs the floor space back.\u003c\/p\u003e \u003ch3\u003eA slower spin is not a slower machine\u003c\/h3\u003e \u003cp\u003eSpin speed is the specification buyers most often read backwards. A wheel turning at high speed carries a lot of energy, makes noise, and puts load through the shaft and bearings every cycle of every day. What actually determines the result is how well the machine resolves where the imbalance sits, and the 7100 resolves it to ±0.35° with a published balancing accuracy of 0.035 (1 g). Add the QuickBal short start-stop cycle and belt-driven one-spin balancing and you get a machine that is measured and calm rather than fast and loud — which, in a small shop where the balancer sits ten feet from where you talk to customers, is worth something on its own.\u003c\/p\u003e \u003ch3\u003e2D SAPE data entry, in plain terms\u003c\/h3\u003e \u003cp\u003eThe 7100 takes offset and rim diameter semi-automatically through its 2D SAPE gauge arm: pull the arm to the rim, and those two values are captured rather than typed. Rim width is entered manually. That split is a genuine cost\/benefit decision rather than a cut corner — the two dimensions that are awkward to measure by hand are the ones the machine takes for you, and width, the one anyone can read, stays a keypad entry.\u003c\/p\u003e \u003cp\u003eThe display is an LED panel with large digits for the weight amount and clear indicators for weight position, and the machine also runs imbalance minimisation and optimisation programs for wheels that will not come right by weight alone.\u003c\/p\u003e \u003ch3\u003eClamping and the wheel guard\u003c\/h3\u003e \u003cp\u003eThe wheel clamps on an integrated flange with a quick nut, and a wheel guard is part of the machine. The guard is not a formality: it is the interlock between the operator and a spinning assembly, and any balancer whose guard has been defeated is a balancer that should be taken out of service until it is fixed.\u003c\/p\u003e \u003ch3\u003eCapacity, and one figure to confirm before you order\u003c\/h3\u003e \u003cp\u003eMaximum wheel diameter is given on this page’s specification table as 37.8\" (960 mm), with a maximum wheel weight of 154 lbs (70 kg). The manual rim diameter range runs to 32\" and the semi-automatic rim diameter range to 25\", with rim width and offset ranges of 1-20\".\u003c\/p\u003e \u003cp\u003ePublished figures for the maximum tire diameter differ: the specification table on this page lists 37.8\", and a second published figure for the same machine lists 32\". The gap is almost certainly the distinction between the largest assembly the machine will physically take and the largest rim diameter you can enter. \u003cstrong\u003eIf your work runs at the top of that range, confirm the figure with us in writing before you order\u003c\/strong\u003e — we will get it straight from Hofmann’s own sheet.\u003c\/p\u003e \u003ch3\u003eWill it fit your bay?\u003c\/h3\u003e \u003cp\u003eThe 7100 is the small-footprint model, which is one of Hofmann’s own listed features for it. The specification table gives 43\" x 39.5\" x 67\". Our product fields give the depth as 40\" rather than 39.5\"; half an inch will not decide most installations, but if you are planning to the inch against a wall or a workbench, ask us to confirm rather than trusting either number.\u003c\/p\u003e \u003cp\u003eNet weight is 154 lbs, and that is a real advantage: it is light enough that repositioning the machine within the shop is a two-person job rather than a rigging job. Power is 230 VAC, single phase, 50\/60 Hz, which is not a standard convenience outlet — confirm what is available in the bay, and budget an electrician if it is not already run. Verifying the supply, the access route and the floor space before ordering is the buyer’s responsibility.\u003c\/p\u003e \u003ch3\u003eSpecifications\u003c\/h3\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eMax. wheel diameter\u003c\/th\u003e \u003ctd\u003e37.8\" (960 mm)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eMax. wheel weight\u003c\/th\u003e \u003ctd\u003e154 lbs (70 kg)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eManual rim diameter range\u003c\/th\u003e \u003ctd\u003e8-32\"\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eSemi-automatic rim diameter range\u003c\/th\u003e \u003ctd\u003e8-25\"\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eRim width range\u003c\/th\u003e \u003ctd\u003e1-20\"\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eOffset range\u003c\/th\u003e \u003ctd\u003e1-20\"\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eMeasuring speed\u003c\/th\u003e \u003ctd\u003eunder 100 rpm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eAngular resolution\u003c\/th\u003e \u003ctd\u003e±0.35°\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eShaft\u003c\/th\u003e \u003ctd\u003e40 mm diameter, 225 mm long\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eWheel clamping\u003c\/th\u003e \u003ctd\u003eIntegrated flange, quick nut\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003ePower\u003c\/th\u003e \u003ctd\u003e230 VAC, 1 ph, 50\/60 Hz\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eCabinet\u003c\/th\u003e \u003ctd\u003e43\" x 39.5\" x 67\"\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eNet weight\u003c\/th\u003e \u003ctd\u003e154 lbs (70 kg)\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003cp\u003eYou will notice we have not quoted a check-spin time.
