Eaton can provide reliable and durable system solutions for concrete mixer trucks. When the truck is driving at high speed on the road or waiting at a traffic light, the drum must maintain a consistent speed. So the use of the Eaton 5423 pump and 5433 motor can provide the required high pressure and high flow for the rotation of the drum.
