CEMB On-car balancer L88

Product catalog summary

General Characteristics
The L88 is the latest development in on-vehicle wheel balancers by CEMB, known for its extensive experience in this field. It is designed to balance wheels of trucks, buses, cars, light trucks, and 2 or 4-wheel drive vehicles. The machine features a new two-speed spin system, with a lower speed for high torque braking of heavy vehicles and a higher speed for cars. It uses microprocessor-based electronics with an adjustable infrared photocell to ensure perfect balancing in two spins, even for critical vehicles. All operations are automated.

Balancing Procedure
To balance a wheel, mark it with reflective tape or chalk, spin the wheel, add a calibration counterweight (30g for cars, 300g for trucks) at the reference position, spin again, read the unbalance value, remove the counterweight, and apply the indicated weight from the measuring panel. On-vehicle balancing is recommended as a finishing step after off-the-vehicle balancing to correct unbalances from centering tolerances, brake discs, or transmission parts. It is essential for heavy vehicles with multi-piece rims where off-the-vehicle balancing is challenging.

Technical Specifications
The L88 machine dimensions are 1030 x 500 x 610 mm, with a package size of 1100 x 550 x 950 mm. The gross weight is 93 kg with a TP2 car transducer and 106 kg with a TPT1 truck transducer. The TP2 car transducer has a maximum capacity of 700 kg and weighs 15 kg, while the TPT1 truck transducer has a maximum capacity of 6000 kg and weighs 28 kg. The machine features angular accuracy of ±2.5, reading accuracy of ±1g, a three-phase motor power of 4 KW (5.5 HP), and a maximum wheel spin speed of 140 km/h. The maximum weight loadable on each car transducer is 700 kg, and on each truck transducer is 6000 kg.

Recommendations
For front-drive vehicles, both wheels should be lifted during the spin to avoid differential damage, recommending the use of two TP2 transducers simultaneously.
