Definition
A Transit Mixer (TM) is the iconic, rotating concrete truck. Its massive cylindrical drum is fitted with internal spiral blades. When loaded at the computerized batching plant, the drum must continuously rotate slowly during transit through city traffic to keep the concrete agitated—preventing the cement, sand, and water from segregating or prematurely hardening before it arrives at the construction site.
Practical Example
A batching plant is 10 kilometers away from the site. The plant operator loads 6 cubic meters of fresh M40 concrete into a Transit Mixer. To delay the setting time due to expected traffic, they add special retarding chemicals. The drum spins at 2 RPM all the way to the site, keeping the concrete in a perfect plastic state until the boom pump sucks it out.
Application in Superwise
Logistical turnaround time (TAT) is everything in concrete logistics. Superwise’s execution module tracks the timeline of every Transit Mixer. The site engineer logs the exact "In-Time" when the TM arrives at the gate and the "Out-Time" when it finishes pouring. If TMs are consistently waiting 2 hours at the gate before pouring, Superwise alerts the PM to a massive logistical bottleneck wasting plant resources.
