Block Machine Installation and Training in Syria: What Happens On Site

Block machine installation and training in Syria follows a fixed engineering sequence, and that sequence sets the calendar more than the shipping does. Seven stages carry a new plant from a prepared site to a signed handover: foundations and site preparation, power and air, mechanical positioning and levelling, hydraulic and vibration tuning, the first mould trial, operator training, and the 7 day and 28 day strength review. Our machines are built for 380 V and 50 Hz, with installed power from 22.9 kW to 104 kW and unit weight from 6,200 kg to 34 t.

1. What must be ready on site before the machine ships?

Installation starts on the concrete, months before the container arrives. Foundation design follows the unit you order, not a generic template. A QT4-15 arrives at 6,200 kg on an 850 x 560 x 20 mm pallet; a QST1800 arrives at 34 t on a 1,400 x 1,400 x 30 mm pallet with a machine footprint of 15,500 x 5,500 x 3,200 mm. The civil scope is yours, and we issue the load data and the anchor bolt layout with the drawings.

Two prerequisites get missed in most plans. The yard needs a route firm enough for a low bed trailer plus room to set the machine down beside the foundation, and the curing area has to hold several days of output, because blocks stand 7 to 28 days before they can be sold.

2. How do the power and air supply shape the schedule?

Our equipment is manufactured for 380 V and 50 Hz, and installed power runs from 22.9 kW on the small unit to 104 kW on the largest moulding machine, so the incoming supply, the main cable and the breaker are sized for the configuration you order. A twin shaft mixer adds 25.5 kW to 75 kW depending on the model, and a stacker adds 3.0 kW or 3.7 kW.

Tell us your site voltage and frequency with the enquiry. Where the supply differs from 380 V and 50 Hz, the change belongs in the electrical build at the workshop, not in a field modification after arrival, so it has to be settled before wiring starts. A machine rebuilt on site costs weeks that a different transformer or a different motor winding would not.

3. How is the machine positioned and levelled?

Lifting is planned from weight, not from habit. Unit weight rises from 6,200 kg through 12 t and 14 t to 34 t across the moulding range, so the crane or the forklift is quoted against the heaviest single piece that has to move, with the lifting points marked on the frame and confirmed in the shipping documents.

Levelling comes next, and this is where the first quality loss hides. The frame is set on the anchor bolts and shimmed until the machine table reads level in both directions, then the bolts are grouted. A frame sitting a few millimetres out of level shows up later as uneven block height and uneven compaction across the pallet, and the operator blames the mix for weeks instead of the base.

4. What happens during hydraulic and vibration tuning?

Rated pressure is set at 25 MPa on QT4-15 and QT5-15 and at 31.5 MPa across the rest of the moulding range, while vibration force steps from 58 kN and 68 kN at the small end up to 280 kN on QST1800. Tuning means matching those two settings to the mix in front of you, not to a figure printed on a plate.

Start on the low side and work up. Excessive vibration force throws the mix out of the mould and leaves a block with broken edges, while too little leaves the face open and drops the 7 day strength. Cycle time is the third lever: 15 to 20 seconds on the small machine, 15 to 23 seconds across the QST series and 15 to 25 seconds on QST1200 and QST1800, so a shorter cycle only pays if the block still compacts.

5. What does the first mould trial prove?

The first mould trial is the acceptance point of the whole installation, and it is decided on measured blocks. A 390 x 190 x 190 mm hollow block runs 5 blocks per mould on QS800, 10 on QS1000 and 12 on QS1500, and a 200 x 100 x 60 mm paver runs 16, 24, 32 and 40 blocks per mould from QS600 to QS1500. Every block in the first pallet is measured, weighed and marked.

The trial proves four things: that the mould is set to the correct height, that the feed box fills the mould evenly, that the mould and the pallet align through the cycle, and that the demoulded block holds its corners. If the mix is right and the block still comes out short, the fault is mechanical and it gets corrected before training starts rather than after.

6. What does operator training cover?

Operator training runs on the machine with production material, on both shifts, so every crew sees the same procedure rather than hearing it second hand. The list has five items: mould change, pallet change and pallet feed adjustment, hydraulic maintenance, the daily inspection sheet, and safe shutdown.

Mould change is taught first because it is the task that gets rushed. The bolting sequence, the cleaning of the mould box and the setting of the height stop are taught as a fixed routine that ends with a torque check, and the crew changes the mould on its own before the commissioning work ends.

Hydraulic maintenance covers filter and oil condition, seal inspection and the pressure reading logged every shift. The daily sheet records pressure, vibration force setting, cycle time, pallet condition, limit switches and any leak, and the shift leader signs it. Safe shutdown leaves the machine in a known state: cycle stopped, mould raised, power isolated, pressure released, cabinet locked before anyone reaches into the mould area.

7. How do the 7 day and 28 day checks close the job?

The installation is not finished on the day the machine runs. Sample blocks are cured and tested at two nodes, 7 days and 28 days, and those readings decide whether the mix or the machine parameters get adjusted. If 7 day strength sits under the target, the first move is usually cement dosage, which commonly runs 6% to 12% with 200 or 260 kg per cubic metre, and the second is compaction time.

Parameters are then locked in and written into the handover sheet, together with the cycle time, the pressure setting and the vibration force setting for each product. Those three numbers are the reference the crew runs on afterwards.

To plan the schedule, send us the block types and sizes you will sell, the raw materials available to you, your pallet size, your site voltage and frequency, and your destination port. We return a dated installation and training plan with the configuration behind it, stage by stage, so the shipment and the site work land in the same week.
