concrete mixer truck's speed

Vehicles belonging to urban transport type vehicles, most of its transport time to change directions, yield to pedestrians and vehicles traveling movements, not possible to do maximum speed. Asphalt Mixing Plant, the truck is refitted by the chassis, the vehicle center of gravity than the center of gravity chassis before modification has significantly increased; while its transit led the concrete mixing drum, rotate it toward the center of gravity offset mixing drum rotation direction, thereby the axis of concrete mixing machine tube to the center of gravity in the vertical plane, so that affects the vehicle driving stability, easy to roll when cornering, especially at high speeds, it will result in a higher rollover accident rate. Jicha Sharp, and are often the main cause truck overturned.
Based on the above understanding, their high center of gravity vehicles, driving traffic complexity, as a city truck that objective existence, in its use should pay close attention to the driving stability and prevent rollover. Manufacturers should not be highlighting its maximum speed when not possible consequent rollover accidents caused warnings to be effective. But not in manual annotation within the chassis for the vehicle maximum speed maximum speed, does not explain the actual driving should comply with "technical conditions" states: "The agitation speeds, maximum speed shall not exceed 50km / h". Therefore, the manual should be fully expressed at high speed will bring high risk of rollover accidents.
