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 Disadvantage

s

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
