The half slab long line offers mechanized or automated work phases. The Elematic Plant Control takes care of production planning, line control and machine operations.

The service functions and material storage flows are optimized according to production needs. Reinforcements are produced just-in-time and automatically moved to the correct production station. Two side-shifters and a reinforcement wagon with a boom crane transport them efficiently. The long line also has a flexible side form stock and an efficient form handling process.


An automatically produced load list shows how many pieces of each form length are required in the process. A high-pressure washer – 400 bar – takes care of cleaning. The casting bed features strong steel foundations with heating pipes to accelerate concrete curing. The bed is totally planar, and it is equipped with a removable standard side form on each side.  An automatic plotter marks slab widths, lengths and recesses on the bed. This ensures accurate dimensions and minimizes errors. In addition, the line features the option to change machines on both ends of the line, for decreased waiting times during the process.
An automatic casting machine provides fast and accurate high-capacity casting with efficient compaction.

The half slab long line needs an area of 5 200 m2 for production, and the total land area required for the operation is 15 500 m2. The line includes 6 beds of 150 meters in length.


Precast slab production on the half slab long line takes place as follows:

  • Demolding
  • Bed cleaning
  • Furnishing
  • Reinforcing
  • Concrete distribution
  • Casting
  • Curing
  • Storing

On a long line, machinery and work teams move separately according to process needs.


The factory is designed to work in 3 shifts.

There are 11, 13 and 10 people per shift in the production hall, for a total of 34 people.

Reinforcement shop: 8 + 8 + 6
Product storage: 2+2+2
Maintenance: 2+1+1
Quality control and concrete laboratory: 1 + 1 +1
Batching and mixing plant: 1+1+1

In total, there are 26 people in the morning shift + 27 people in the evening shift + 22 on the night shift = 75 people.

*White collar, maintenance people, special tasks, etc. not included. The number of personnel needed to operate the line is strictly a non-binding indicative estimate.


All machines on the half slab long line Floor line meet EC Machine Directive requirements. The machinery is designed to keep noise levels low and enhance safety. The line comes with thorough and clear user, maintenance and safety manuals in the required language.
