Labour and Staffing for a Block Factory in Syria: Shift Patterns

Labour and staffing for a block factory in Syria is decided by the automation level of the line and by the shift pattern you run, not by the number of machines standing in the shed. A single automatic line that removes pallet handling can save 12 to 16 operators per day against a manual line producing the same output, because the crew follows the material flow: batching and mixing, moulding, green block handling, cubing, curing and testing. Set the shift pattern and the target output first, then count how many people each station needs.

1. What jobs does a block factory crew cover?

A block plant crew is a fixed list of stations, and every station has to be staffed whenever the machine runs. Batching and mixing: one operator loads aggregate and cement, holds the water to cement ratio between 0.35 and 0.45, and keeps the mixer feeding. Main machine operator: runs the moulding machine, keeps cycle time between 15 and 25 seconds, and watches pressure and vibration. Green block handling: taking freshly moulded blocks off the pallet and moving them to the curing area, the heaviest manual job on a line without automation.

Cubing and strapping: stacking cured blocks into a stable cube that can be moved and loaded. Forklift and yard: moving cubes and pallets through the 7 day and 28 day strength nodes. Quality and records: checking dimensions and strength, and writing down the batch. Supervision is a separate line, and on a manual line these stations need six to eight people per shift before a supervisor is counted.

2. How many workers does a block factory need?

On a two shift plant the total lands between roughly 8 and 30 people, and automation level moves the number more than output does. A manual or semi-automatic line carries the flow by hand: green blocks come off the machine and every movement is a person, so a manual plant adds bodies as output rises. An automatic line replaces those stations with the pallet feeder, the stacker and the strapping machine, and where an automatic line removes 12 to 16 operators per day the same output leaves a crew of six to eight per shift.

The figure is a range because the crew is set by station count, and station count is set by how much of the material flow the machine handles. Ask which stations a machine package covers before asking how many people it needs.

3. How do you work back from output to headcount?

Derate the machine before you count people. Nameplate output is a plate figure, and real output runs at 70% to 80% of it once curing time, mould changes, breakdowns and pallet returns are allowed for. Two shifts give roughly 500 shifts a year, not 700. Take the target daily output, divide it by the derated output per shift, and you get the machine shifts you really need; then assign people per station per shift.

The heavier machine does not automatically need more hands. A QST8-15 at 44.9 kW running 90,000 standard bricks in an 8 hour shift uses the same station crew as a QST1800 at 104 kW running 220,000 bricks, because the crew follows the flow, and the larger machine needs a crane and a stacker rather than extra people. Output rises faster than headcount on an automatic line, and that gap is where the saving sits.

4. Which machine-side options cut the crew?

Three items do most of the labour removal on our lines. The QS-1200 automatic pallet feeder weighs 1,300 kg, draws 3 kW and has an up-board cycle of about 13 seconds, so board feeding stops being a manual job. The QS-1200A low level stacker weighs 18,000 kg, runs 34.15 kW in total and cycles in 15 to 18 seconds per layer, which replaces cube stacking and takes the heaviest lifting off the crew. The QSSX-16A top rotating strapping machine cycles in 15 to 18 seconds, draws 3.1 kW and runs on 380 V / 50 Hz, so one operator straps a whole cube.

On the smaller moulding machines a stacker at 3.0 kW covers the same job, and the manual handling stations fall away one by one. Each removal is one less person per shift, and the effect compounds with the number of shifts you run.

5. Training and rotation: who does what

Headcount matters less than what each person can do. One operator who can run the main machine, the batching panel and the stacker covers three stations and lets a shift run with a smaller crew, while relying on a single specialist creates a stop every time that person is away. Mould changes are the clearest case: a mould swap stops the machine, so at least two people on the crew should be able to release, align and refit a mould without waiting for an outside fitter.

Hydraulic maintenance is the second case: filter and oil checks, seal replacement and pressure checks belong to a named person on a schedule, not to whoever is free. Rotate operators across stations during the first months, and keep a written record of who is signed off on which machine.

6. Set the shift pattern first, then the crew size

Start from the shift pattern and the target output, then count stations, then choose automation to remove them. Labour is a long term line, not a purchase: a plant running two shifts for 500 shifts a year pays a crew in every one of those shifts, while the machine is paid once. Where an automatic line takes a manual crew from 16 people down to six, that saving is larger than most price differences between two machines in the same output class, and automatic lines of this kind commonly pay back in 12 to 30 months.

For a crew plan for your site, send the shift pattern you intend to run, the target output per shift, the block types and sizes, the pallet size, your site voltage and frequency, and the destination port. We balance the configuration against the number of people you want to run it with. Tell us your local labour conditions and we build the station list around your shift pattern rather than around a fixed crew number.
