EM 7340

A high band display balancing machine, the EM7340 is the ideal instrument for vehicle repair workshops and tyre repair centres.
The control panel with dual display and three-dimensional graphics is designed to be user-friendly.
The body’s front inclination reduces ground dimensions and lets the operator work in more ergonomic conditions.
Automatic acquisition of wheel distance and diameter, low balancing speed and automatic weight application position search, ensure sped and precision; like the vast software package complete with Alu-P, OPT Flash, three separate working environments, along with Shift Plane, Hidden Weight e Split Weight programs.

Principal characteristics

- Electronic balancing machine with microprocessor for off-vehicle wheels of cars, vans and motorcycles.
- Low balancing speed (98 rpm) reduces wheel spin times, reduces the risks due to rotating parts and saves energy.
- The body’s front part is tilted for an optimal working position and easier access to the weight tray.
- Automatic sensor for measuring the distance, diameter and for applying adhesive weights in Alu P programs.
- Outer automatic sensor for length measuring (on request).
- Automatic position search (RPA): having launched this program, the machine automatically positions the wheel in the weight application point.
- Automatic wheel clamping at the end of the spin.
- Wheel-holder shaft clamping brake.
- STOP button for immediate machine shutdown.
- Side flange holder on the guard support.
- Cover with trays to take weights of all kinds and the most commonly used accessories.
- Automatic start by lowering the wheel guard.
- Luminous digital dual display with 3D graphics.
- Simple, user-friendly keyboard for data input and program selection.
- Processing unit with microprocessor (16 bit)
- Resolution: 1 g (1/10 oz).
- Unbalance values displayed in grams or ounces.
- Option of displaying unbalances rounded up/down.
- Balancing modes available:
Standard dynamic on both sides of the rim
Alu / Alu P seven different options for alloy wheels (with profile measurement)
Dyn. Moto dynamic on both sides for motorcycle rims
Alu Moto dynamic on both sides for motorcycle alloy rims
Static on one plane only.
- "Shift Plane" program (in Alu P) for use with weighs in multiples of five grams, with no need for partial cuts (Corghi Patent).
- "Hidden Weight" program (in Alu P mode) which subdivides the adhesive weight for the outside into two equivalent weights positioned behind the spokes of the rim.
- "Split Weight" program (motorcycle program) allowing weight to be divided into two parts for positioning on the spoke’ sides.
- "OPT flash" program for the rapid optimising of wheel running noise levels. A single tyre shift on the rim and a balancing spin will cause the machine to display:
• the real wheel unbalance (the OPT procedure is completed if this is within the acceptable range);
• the minimum unbalance which is obtained by further rotating the tyre on the rim.
- Utility programs:
• calibration;
• service;
• diagnostics.
- Three work environments which allow three different operators to work at the same time without having to reset the data.
- Pneumatic ring nut (on request) for automatic wheel clamping. Alternative solution to the conventional automatic - Quick Lock system.
- Optional pneumatically operated TT50 wheel lift with lifting capacity up to 70 kg. Lifts the wheel and centres it precisely on the balancing machine shaft.
