Automated Cargo Transport Systems Plus Real-time Silo Level Information

The Company Automated Cargo Delivery System developed by owner of cement transport company 30% Reduction in number of tractors & drivers Allows 100% consistent unloading procedure Offers real-time inventory information Significantly improves on-time delivery

Traditional Situation Driver arrives at site & connects hoses Driver requests permission to begin unloading Delivery of product takes approximately 40 minutes

Traditional Disadvantages Tractor & driver must be present to unload On-time delivery is critical, cannot be proactive Waiting time can be a significant factor Problems due to driver unloading errors Problems associated with faulty bin HIGH alarm

Automated Cargo Transport System Increases deliveries/day/tractor Tremendous dispatch flexibility 30% Reduction in number of tractors & drivers Real-time inventory management

The Patented Process ACTS computers control unloading process using patented algorithms to cycle valves based on silo level and tank pressure. Tanker can be delivered in “off” hours and be utilized as a secondary silo. This frees the tractor and driver to deliver at other sites. ACTS control system uses the unloading process to give you a competitive advantage.

Primary Components Located at Ready Mix Plant Real-time radar level sensors on silos Blower Control panel Located on Tanker Control valves Pressure transducers Control panel

System Overview

Silo Level Sensor Utilizes reliable radar technology No moving parts Provides continuous real-time level information

The Blower Installed at ready mix plant Runs at constant RPM - No driver panic shutdown - Lower cost to operate - Less maintenance

Silo Control Panel Mounted at ready mix plant - NEMA 4X protection Uses PLC/Digital technology Controls silo level & blower Silo levels tracked on: - Intranet or Internet

Tanker Control Panel NEMA 4X protection - PLC - Solenoid Valves - Pressure Sensors - Pressure Gauges Easy access for manual operation permits deliveries at non-automated plants

Control Valves Automated valves Controls product flow Avoids plugged lines

Two Quick Connections Communicatio n Connection Gladhand Compressor Connection
