DYNO TRUCK, power bench tester for trucks

Is a computerized diagnostic system for the measurement of the torque and the power performed by a Truck or Bus in running order. Indispensable to check and analyse the performance parameters of two or four-wheel drive trucks (also electronically controlled). Mechanically designed to suit any loading condition, this dynamometer allows to test vehicles up to 16 ton. per axis, The following measures can be verified simulate and displayed:

• MAXIMUM POWER AT THE WHEEL AND RELATED GRAPHIC REPRESENTATION
• MAXIMUM POWER AT THE ENGINE AND RELATED GRAPHIC REPRESENTATION
• TORQUE TO THE WHEEL AND ENGINE AND TREND CHART
• SIMULATION AT CONSTANT RPM
• SIMULATION AT CONSTANT SPEED
• SIMULATION ON CONSTANT TRACTION
• MESURE OF THE DISCREPANCY OF SPEEDOMETER
• ROAD SIMULATION

The parameters are measured and corrected through a barometric station integrated in application of the normalization of the curves: DIN 70020, EWG 80/1269, ISO 1585, j1349 SAE, JIS d1001.

DynoTruck power test bench is also equipped with a range of sensor and probe for the acquisition data of analog parameters such as pressure manifold, ambient pressure and temperature, engine oil temperature, exhaust gas temperature, acquisition revolution engine through inductive caliper, fuel comsimption, (optional) and acquisition of engine parameter through OBDII connection (optional).

The software offers a variety of options to customise the parameters displayed. It allows to elaborate your tests and draw up the results in several, clear reports. The tests can be saved in a logical structure, and the most significant can be overlapped for comparative purposes, to verify and prove the competence of your professional skills. A special option allows multiple sessions up to eight test.

Reassuring the preservation of the personal integrity as its main goal, the safety equipment allows maximum freedom with mechanical locking. In the version with the device ESS the first axis is dragged into rotation to the same speed of the steering axis while solving the problems brought by electronic systems of traction and stability control (ESP, ABS, etc.) varying the wheelbase setting (4WD version) or when locking the rollers and lifting the metal bar in order to move a vehicle in/out, to make operations easier.
