Tire changer: voltage: 110v 60hz power: 0.75Kw 1.5Hp working pressure: 8-10bar wheel clamping system: 4 clamps-internal rim clamping outer: 10 -18 rim clamping inner: 12-21 max.Tyre diameter: 38 max.Tyre width: 11 tire balancer: voltage: 110v 60hz power: 0.28Kw balancing accuracy: 1g balancing speed 200r min positioning accuracy: 1.5 Cycle time: 8s rim diameter range:10 24 256mm 610mm rim width 1.5 -20 Back spacing: 190mm noise level: 70db tire changer: hpdmc advanced positioning system lets you clamp a wheel at any point in the clamping range. Precisely positioning the clamps can help ensure the wheel is held perfectly still during the tire changing process. This can improve the accuracy and efficiency of the operation tire balaner: the tire balancer has the ability to automatically input the rim size by using a measuring scale and it eliminates the need for the user to manually enter the rim diameter which can improve accuracy and efficiency wide application: the heavy-duty tire changer can withstand the continuous daily use in a commercial tire shop without wearing out prematurely. These different modes of the tire balancer correspond to the various ways the balancing weights can be attached to the tire wheel assembly Size: [810+7900]
