Perfect alignment

Cemb: garage equipment

 

Thanks to laser technology, CembArgos can measure toe, camber and thrust angles in just five seconds. Manageable through an app on a portable device, all procedures are totally guided. Great news also for balancers and tire changers

A century ago angles were measured with string systems. Yesterday with clamps, detectors and optical targets. Today, we can do this through Argos’ four columns. All we have to do is stop the vehicle between the Argos columns, and a high-tech 3D scanner measurement system does the rest, giving us the feedback in less than five seconds. Angle measurements thus becomes faster and more precise – including all subsequent controls during the adjustment procedure. The new aligning system is suitable for passenger cars as well as light commercial vehicles and can be combined to either a lift, a pit or even an ordinary acceptance lane and does not require any wheel run-out or targets removal, which increase working times eroding profitability.

                                                   

             

Measurements in a blink

Once the car is positioned on the plates, through a monitor and images captured by cameras, the operator quickly measures all the angles ​​of the vehicle: toe, camber and thrust angles. Since there is no physical contact between the system and the wheels, no additional tools need to be applied just as unnecessary is the manual repositioning of the columns when measuring cars with a different wheelbase. No need even for a levelled lift. The system automatically starts as the vehicle enters the measuring area and, automatically recognizing the vehicle’s wheelbase, will then proceed to filter and retrieve only information about vehicles with that wheelbase from its database, speeding up all operations. Its advanced software is very intuitive and can be remotely controlled, thanks to an app for Android devices. The operator works with a tablet or smartphone from inside the car; with automatic unlocking plates (optional), even getting out of the vehicle to unlock the turn plates is totally unnecessary. The system leaves large free spaces around the deck to operate on the wheels. The maximum dimensions required for installation are 4.7 m on one side and 3.165 to 3.665 on the other. Powered by 230 volt alternating current, it requires 0.6 kW of power and absorbs 2.6 amps. It comes standard with Android apps, steering lock, pedal lock, manual docking turn-plates and wireless keyboard; Among the accessories we find automatic docking turn-plates, 50 "monitors with support column and wireless printers. Argos is available in three different version: Full, which measures vehicles on-floor and at a fixed height ideal for both reception lane and adjustments with a lift; High, which measures vehicles at a fixed height ideal for adjustments with a lift; Pit, which measures vehicles on-floor ideal for adjustments in a pit. The DriveThru version, specific for reception lane, monitors all vehicles upon acceptance and detects a greater number of vehicles in need of adjustments, thus increasing both business volumes and customer satisfaction.

                                                                                       

Quick and precise balancing

Balancers use common scanners available on the market to detect the distance and diameter of the rim. Cemb technicians, on the other hand, recently came up with a specific wheel balancing sensor system, the 3D Laser Scan. Brighter laser spots accurately identify the application point for stick-on weights and, in general, the sturdiness of the system is superior to anything previously seen on the market making even maintenance operations easier and quick. During the measurement phase, it grants a faster and more accurate reading of rim dimension, even in case of complex profiles. 3D Laser Scan will be available on the ER90 Evo and ER100 Evo balancing machines, the latest versions of two models that already boasted a Spotter system and many other automatic functions: to balance the wheel all you need to do is, mount it on the balancer and close the protection.

 

Made for big wheels

The SM 1100 is a new tire changer dedicated to large wheels, such as SUVs and vans. Recommended for operations on oversized and heavy cars and vans with 12″ to 30″ wheels. The system is lever-less and the wheel locking system can be either manual or pneumatic. The new synchronized bead braking system allows you to control tool penetration and quickly and efficiently disengage the work area, making it ideal for sequential bead braking operations. Working on steel wheels is possible through an arm equipped with double-acting cylinder. The new independent floating bead presser in the vertical pole assists the operator while installing and disassembling low profile or even run-flat tires. The pneumatic lift has a working capacity of 85 kg.

                                                      

 

The company

Cemb was created by Luigi Buzzi in Mandello del Lario, same town as Moto Guzzi, in 1946; The same year he produced the first balancer for industrial applications. In 1952, the first wheel balancer was born, thus launching its first line of garage equipment that represents one of the three pillars of the company’s production down to this day. The other two are the Industrial line, used also for automotive OEMs (for example, balancing engine shafts), and Vibration, a full range of fixed and portable equipment for vibration measuring and correction of the unbalances on large rotating machines.

 

Prime Factory mode

In many balancers reference planes are identified with the correction planes on which you choose to place the counterweights. This method can cause a great waste of time and counterweight as correction planes, on aluminium wheels, are too close to the centre of the wheel and have a reduced diameter. Therefore the system might need corrections even if the residual unbalance on reference planes is less than a certain tolerance which is normally 5 or 7 gr. The Prime Factory Mode program uses the same method used by vehicle manufacturers on their standard equipment. Even if stick-on weights are used inside the rims, it analyzes and verifies the residual unbalance on the external planes of the wheel, with the purpose of reproducing the real tolerable unbalance, bringing back the residual unbalance value to a factory value, saving both time and counterweights.

 

                                                              

Technology against unbalances

It is a known factor that static unbalance is the greatest cause of vibrations perceived by drivers. While many wheel balancers are capable of indicating the pure static unbalance value, it is quite difficult to assess the residual unbalance value detected thus increasing the vibrations perceived by the driver. This leads to an inadequate balancing procedure with the consequent waste of time and stick-on weights. Thanks to Cemb’s new OPB (One Plane Balancing) software, these setbacks are overcome by providing a single ideal correction plane obtaining a substantial reduction of the static unbalance and, at the same time, minimize the dynamic unbalance. With the aid of Laser Spotter technology, Cemb equipment can determine and identify the single spot inside the rim where both static and dynamic unbalance can be corrected through a single stick on weight  saving a lot of time and materials.
