Mobile diesel generator sets, also known as trailer type gensets, are designed to provide prime or backup power for field construction and are widely used in the power, mobile, telecommunications and civil industries. Trailer traction is required for the trailer type gensets to move. Compared with emergency power supply, maneuverability is poor, but size and weight are small and the cost is low. The mobile diesel generator sets can be divided into two-wheel, four-wheel, six-wheel, eight-wheel, single-axis or two-axis structure according to the power size, which can be equipped with built-in large-capacity running fuel tank with spring damping, braking function, traffic warning sign, rain cover and visual operation control screen for user maintenance and operation.
