Block Machine for Sale in Amman: Layout, Moulds and City Delivery

A block machine for sale in Amman rarely lands on open ground. It lands on a walled plot inside the city, a house behind, a street that carries traffic all day. That changes the order of the questions: output comes later, and first comes whether a 15,500 mm frame, its curing pallets, the aggregate stock and a turning flatbed can share that ground.

Every figure below is a machine dimension, not a clearance, so tape the plot yourself.

What floor area does the machine itself take?

Start with the frame rectangle. A QST1800 is 15,500 x 5,500 x 3,200 mm and weighs 34 t. A QST1500 is 11,500 x 4,550 x 2,800 mm and weighs 20 t. At the compact end a QST6-15 is 9,450 x 3,300 x 2,700 mm at 12 t.

The length is not padding. The frame carries the mould, the vibrating table and the pallet feed on one line, so it cannot be folded into a corner. Height matters too: 3,200 mm of frame under a standing roof decides whether you keep the roof or lift it. On a city plot the machine runs along the longest wall, pallets leaving toward curing, the mixer behind the operator side.

Weight sets the foundation, and weight does not spread evenly. The press columns and the vibrating table take the load, and the vibration force arrives with it: 280 kN on a QST1800, 220 kN on a QST1500, 95 kN on a QST8-15. Ask for the load plan before the slab is poured. A foundation cast for a lighter machine and then asked to carry 34 t cannot be fixed later.

Where does the pallet route set the shape of the plot?

Every cycle sends one wet pallet out and pulls one empty pallet in. On a QST1800 the pallet is 1,400 x 1,400 x 30 mm, on a QST1500 it is 1,350 x 1,150 x 30 mm. Those pallets, not the machine, fill a city plot: they stand in curing in stacks, and the number in circulation is set by curing time, not shift output.

The loop has to run one way. Empty pallets enter at the feed end, cured stacks leave at the cuber end, the loading bay sits beyond it. If the truck route crosses the pallet route, the line stops while a lorry reverses. Draw the loop as one arrow around the machine rectangle: curing on the long side, stock at the back, gate at the corner.

Three dimensions size the loop. A QS-1200A cuber covers 12,000 x 3,000 mm, weighs about 18,000 kg, stacks to 1,400 mm and handles 3,800 pallets per shift. A QS-1200 pallet feeder covers 3,300 x 1,700 x 2,100 mm and returns an empty pallet in about 13 s. A slow feeder piles pallets in curing, not at the press.

Which block sizes should you tool first?

Tool the sizes the city buys, one at a time. A 390 x 190 x 190 mm hollow block is the wall unit that keeps a plant busy, and it belongs in the first mould. Cavity count follows pallet area: on a QST6-15 a 980 x 680 mm pallet carries 6 hollow blocks of that size and returns 8,640 to 11,520 in an 8-hour shift, while the same pallet carries 32 to 36 standard bricks.

Do not chase the highest cavity count on the sheet. Cavities have to agree with what happens after the press: a forklift clamp takes 500 to 800 standard bricks or 40 hollow blocks per bite, at 10 standard layers or 5 hollow layers, and the cuber stack tops out at 1,400 mm. A mould whose full pallet builds an awkward stack costs you a man on the yard.

On a QST1800 the cycle runs 15 to 25 seconds, so a pallet leaves the press every 15 seconds at the fast end, which is 240 pallets an hour, and 144 pallets an hour at 25 seconds.

What does a second mould set cost you in downtime?

A mould change stops the whole line, because the set leaves as one unit: frame, core, base plate, guides and positioning mechanism. In a wear-resistant alloy steel set machined on CNC to micron level and hardened, the faces are what you buy, and the faces are what wear.

Order the second set with the machine. It arrives with the commissioning crew, gets a trial run on your own mix, and the changeover is learned while the supplier's engineer is still on the plot. Order it a year later and you buy a second shipment, a second commissioning visit, storage for a heavy steel set on ground with no spare corner, and a line that stands still on the day demand turns.

Wear announces itself three ways: flashing on the block edge, height drift across one pallet, product sticking in the cavity. By then the set is taking pieces out of your shift.

How does a 34 t machine come off the truck?

Not with a forklift. A QST1800 at 34 t, a QST1500 at 20 t and a QST6-15 at 12 t are crane lifts. The frame travels in one piece on a flatbed whose deck must be as long as the machine, 15,500 mm on a QST1800. Inside a city the lorry parks parallel to the wall, the crane sets up from the street, and the frame swings over the wall.

Access decides the plan before the crane does. The gate must pass the frame width: 5,500 mm on a QST1800, 4,550 mm on a QST1500, 3,300 mm on a QST6-15. A bend on the approach limits deck length, because a long flatbed cannot be reversed around a corner. Measure the narrowest point and any cable height above it.

Permits sit on your side: the road permit, the parking bay, the working window. Set the delivery date from the permit, not from the machine. A crane booked before the permit is a crane that waits.

What should you send before anyone draws a layout?

Five items make the drawing usable: the plot outline with wall heights, the gate width, the truck route with its turning point, the block sizes you will sell in the first year, and the shift length you can staff. Add the pallet size, because curing is sized from it.

• Machine rectangle: 15,500 x 5,500 x 3,200 mm and 34 t on a QST1800, 11,500 x 4,550 x 2,800 mm and 20 t on a QST1500, 9,450 x 3,300 x 2,700 mm and 12 t on a QST6-15. Take the frame that passes your gate.
• Curing and stacking: 1,400 x 1,400 x 30 mm pallets on a QST1800, 1,350 x 1,150 x 30 mm on a QST1500, and a cuber stack limit of 1,400 mm. Count pallets standing in curing, not pallets in a shift.
• Handling: a forklift clamp lifts 500 to 800 standard bricks or 40 hollow blocks per bite with a 2,000 kg load, so the yard aisle has to carry a loaded forklift.
• Power: 104 kW installed on a QST1800, 69.1 kW on a QST1500, 34.4 kW on a QST6-15, with a 280 kN vibration system pulling on every cycle. The supply has to reach the wall before commissioning.
