Block Machine Manufacturer in Jeddah: Layout, Yard and Site Power

A block machine manufacturer in Jeddah is usually asked for a price before anyone has walked the plot. The press is the predictable part: a QST1800 frame measures 15,500 × 5,500 × 3,200 mm and weighs 34 t, and it holds its 15 to 25 second cycle for years once the ground under it, the yard behind it and the cable feeding it are settled.

Layout and utilities set the real output ceiling. Two buyers order the same frame; one reaches the stated cycle in the first week, the other spends a season on a soft floor, a yard that cannot hold a shift of pallets and a panel that trips when the cuber starts. That difference is drawn on paper.

What does the machine footprint actually occupy?

The plan area in the catalogue is the frame, not the working envelope. A QST1800 occupies 15,500 × 5,500 mm in plan, a QST1200 11,500 × 4,550 mm, a QST8-15 9,800 × 3,600 mm and a QST6-15 9,450 × 3,300 mm. Around that rectangle you need four strips: the pallet feeder in front, the cuber run behind, a pump-side maintenance aisle, and floor clear enough to pull a mould out sideways.

The cuber run is the part buyers underestimate. A QS-1200A covers a floor area of 12,000 × 3,000 mm at about 18,000 kg, and the double-station QS-1000G-C measures 19,000 × 7,500 × 5,500 mm overall. Put press and cuber on one straight line so a loaded pallet never turns a corner.

How much curing yard does one shift of output demand?

Pallet count decides the yard, and the cycle decides the pallet count. A QS-1200A clears about 3,800 pallets per shift, a QS-1000G-A about 1,700, and the pallet feeder returns an empty board in about 13 seconds. Every board sits in curing before it comes back, so size the yard on the pallets in curing at one time, not on the blocks you sell that day.

Output sets how fast the fleet fills: up to 220,000 standard bricks per 8-hour shift on a QST1800, up to 120,960 on a QST1200, up to 90,000 on a QST8-15. Board size fixes the footprint of each stack, 1,400 × 1,400 × 30 mm, 1,350 × 880 × 25 mm or 980 × 860 × 22 mm.

Then add the aisles. A clamp rated 2,000 kg takes 500 to 800 standard bricks in one bite, ten layers at a time, and it needs turning space at the end of every run.

Silo, stockpiles and water on the same plot

Cement comes by tanker, so the silo belongs where a tanker can stand and blow without reversing across the block yard. Keep it on the batching side, on a kerbed hardstanding, with a short screw feeder.

Aggregate bays follow the loader, not the mixer. Sand, gravel and crushed stone powder need dividing walls; a bucket that spills gravel into the sand bay changes the grading of every batch after it. The mixer accepts aggregate up to 80 mm for pebbles and 60 mm for crushed stone.

Water is two systems: mixing water at the batching point, curing water at the yard. Curing draws the larger volume, and wash-down from the mixer and the boards should run to a settling pond, never across the finished pad.

What shares the power entry with the block machine?

The press nameplate is half the supply. Installed capacity is 104 kW on a QST1800, 69.1 kW on a QST1500, 57.6 kW on a QST1200, 44.9 kW on a QST8-15 and 34.4 kW on a QST6-15, with the stacker adding 3.7 kW or 3.0 kW.

Everything around the press carries its own motors. A QS-1200A cuber is rated 34.15 kW, a QS-1000G-C 44 to 45 kW, a QS-1000G-A 15 kW, the pallet feeder 3 kW, and a twin-shaft mixer 25.5 to 75 kW by size. Write the single-line diagram before the panel is built: list every motor and mark which ones start together.

The QST1800 vibration system delivers 280 kN at 3,800 to 4,500 vibrations per minute against a 31.5 MPa hydraulic pack, and a supply that dips will stall a cycle in the middle of a mould. Curing sub-cars on lithium batteries remove the rail feed entirely; track-powered cars do not.

Truck, loader and forklift access before anything is poured

Access is a civil decision. Frames arrive at 34 t, 20 t, 17 t, 14 t or 12 t, and the truck carrying one has to reach the unloading point, stand level and leave without a shunt onto soft ground. Measure the gate, the turning circle and the height of any cable over the lane.

Keep the loader route to the stockpiles apart from the forklift route to the curing yard; two heavy machines meeting at one blind corner is how a stack of green blocks reaches the ground. On a tight plot, a crawler cuber at about 5,000 kg walks at about 2 km/h and folds to 5,000 × 1,900 × 2,500 mm for transport.

The civil sequence from survey to grout

Run the work in one order and the machine lands once. Survey and levels first, then a soil report taken at the press and cuber positions rather than at the gate. Set the centreline and the anchor bolt templates from the manufacturer's general arrangement drawing; those templates and the cable ducts are the two items nobody can move cheaply later.

Cast the pad as a single pour under the press and check level along the whole cuber run. Let it reach its specified strength, proven by cube tests, before any load goes on it, because a pad loaded early cracks under a 34 t frame and does not come back to level. Grout the base plates, then cut drainage falls away from the panel.

What do you walk the land with before signing, and what do you send us?

Walk the plot with a tape, string and a notebook, and settle seven items before you sign anything:

• Mark the press plan and the cuber run at full size on the ground, 15,500 × 5,500 mm and 12,000 × 3,000 mm, aisles included.
• Mark the curing area for the boards in the fleet at 1,400 × 1,400 × 30 mm, plus the forklift turning space.
• Stand where the cement tanker will stand and watch the reverse; hesitation means the silo sits in the wrong place.
• Trace the loader route from the gate to the stockpiles and confirm it misses the curing yard.
• Locate the power entry, list what already runs on it, and fix the panel position away from dust and forklift reach.
• Walk the fall of the ground and find where water leaves the plot after rain and after wash-down.
• Measure the gate and the lane, note overhead lines, and record the soil in any open excavation.

Send those findings as a scaled plan with a north arrow, levels, press and cuber positions, silo and stockpile areas, panel position, gate width, product mix and mould set, shift pattern and curing method. A layout built on that drawing answers the site you own; a layout built on a catalogue page answers a site nobody has.
