At the same time, a field controller is set up on each pier, a pumping station and two sets of launching jacks are controlled by a field controller with a

Batching, Mixing, Transporting, and Handling Concrete

Concrete is sometimes mixed at the jobsite in a stationary mixer or a paving mixer (Fig. 10-2). Stationary mixers include both onsite mixers and central mixers in ready mix plants. They are available in sizes up to 9.0 m. 3 (12 yd. 3) and can be of the tilting or nontilting type or the open-top revolving blade or paddle type. All types may

Traction and Tractor Performance

The understanding and prediction of tractor performance has been a major goal of many researchers. Tractor performance is influenced by traction elements, soil conditions, implement type, and tractor configuration (Brixius, 1987). It is necessary to understand traction performance to predict tractor performance in the field.
