What "300 Pieces per Hour" Actually Means When You Buy a mobile block machine in stock
Every output figure on this page is tied to a specific block dimension and mould count — the only honest way to quote capacity.
When I first started quoting machines to contractors in the Gulf, I noticed a pattern: buyers would compare hourly numbers across suppliers without checking which block size those numbers assumed. A machine listed at 300 pcs/h on a 400×200×200 mm hollow block might only produce 180 pcs/h when switched to a denser interlocking paver format. That gap between expectation and reality stalls projects before the first block is cured. The QMJ4-45 mobile block machine in stock ships with a capacity sheet that names the exact format behind every output claim. [NEED_CITE: block format effect on cycle time in egg-laying machines]
Why Stocked Availability Matters on a Project Deadline
Construction timelines rarely wait for a six-week production window. When a contractor in Riyadh lost two weeks to a delayed block shipment, the penalty clause cost more than the machine itself would have. A mobile block machine in stock for fast dispatch lets you bridge that gap — the QMJ4-45 ships as a single compact unit that fits inside a standard container, dismantled for loading and reassembled on arrival with minimal foundation work.
Container Loading and Arrival Timing You Can Plan Around
The QMJ4-45 measures 1550 × 1335 × 1580 mm and weighs approximately one tonne, which means one unit loads into a 20-foot container alongside its standard mould set and spare hydraulic seals. Dispatch lead time is quoted at inquiry, not after payment, so your procurement team can build an arrival estimate into the project schedule from day one.

Reading the Spec Sheet Like a Site Engineer
The 7.4 kW total power draw tells you what generator capacity or site connection you need before the machine arrives — undersizing the supply causes voltage sag that weakens vibration force and produces low-density blocks. The four-pole guided orientation with an ultralong bearing keeps the pressure head aligned with the mould box throughout each stroke, which is what holds block dimensions within tolerance across a full production run. Pallet-free egg-laying design removes an entire inventory variable: no pallets to purchase, store, rotate, or replace, which matters when your curing area is a cleared section of the building site rather than a dedicated yard. The semi-automatic jog control means one operator runs the cycle while a second handles the mixer feed — labour allocation you can plan before the crew arrives.
The Cost of Skipping the Voltage Conversation
One site I worked on outside Jeddah had a QMJ4-45 class machine arrive with a 380 V motor wired for 50 Hz, but the project generator was set to 60 Hz. The motor ran, but the vibration frequency was wrong for the local sand’s moisture content — blocks crumbled at demoulding for three days before we traced the issue back to the frequency mismatch. Confirming voltage and frequency before the machine leaves the factory avoids this entirely. [NEED_CITE: voltage and frequency standards by export market]
Why Buyers Source This Machine Here
Block machinery is the single product focus, which means the QMJ4-45 is specified alongside its moulds, spare seals, and electrical components as one matched package rather than assembled from separate vendors. Dispatch lead time and container loading plans are quoted at inquiry, giving buyers a realistic arrival estimate before committing. Factory test records document the machine running with the buyer’s chosen mould installed, not a generic test block. Mould design covers the formats the buyer’s market actually sells — hollow blocks, interlocking pavers, curb stones — and custom drawings are accepted when standard moulds do not match local demand.
Documentation & Verification
- Capacity calculation sheet stating the exact block format and mould count behind each output figure
- Factory test record with the buyer’s selected mould installed before dispatch
- Voltage and frequency confirmation sheet signed before production begins
- Packing photographs showing machine dismantling and container loading arrangement
- Electrical schematic matching the installed imported components
- Customs documentation support for destination-country import requirements
Installation, Commissioning & Support
- The 1550 × 1335 mm footprint requires a flat, compacted ground area — no poured foundation needed for egg-laying operation
- 7.4 kW power draw demands a dedicated circuit or generator rated above 10 kVA to prevent voltage sag during vibration cycles
- Machine ships dismantled for container loading; reassembly on site covers orientation bearing check and mould alignment
- First-run commissioning includes jog control calibration and vibration timing matched to local aggregate moisture
- Operator training covers mould change procedure across hollow block, interlocking, and curb stone formats
- Hydraulic wear parts and spare electrical seals shipped with the unit to cover initial replacement intervals
What to Include in Your Inquiry
Tell us the block format you plan to produce and the daily volume your project requires, so the capacity calculation reflects your actual output rather than a catalogue default. Share your site voltage, frequency, and the local aggregate you intend to use — sand salinity and moisture content affect both the mix and the vibration setting. If you have a project deadline, state it upfront so dispatch timing can be confirmed against current stock.
Frequently Asked Questions
Q: Which QMJ4-45 units and standard moulds are currently available for immediate dispatch?
A: Stock levels change as orders are booked, so we confirm available units and standard mould inventory at the point of inquiry. The standard mould range covers 400×200×200 mm hollow blocks, 400×150×200 mm blocks, and common interlocking paver formats. Custom moulds are produced to buyer drawings with a separate lead time.
Q: What is the dispatch lead time and estimated arrival at my destination port?
A: Dispatch timing depends on current stock position and container availability, both quoted at inquiry. Sea freight transit time varies by destination port. We provide an arrival estimate before order confirmation so your project schedule can account for the shipping window.
Q: How is the QMJ4-45 dismantled and loaded into a container for shipment?
A: The machine is dismantled into main assemblies — frame, mould box, vibration unit, and electrical panel — to fit within a standard 20-foot container alongside the mould set and spare parts. Packing photographs document the loading arrangement before the container is sealed.
Q: Can the voltage and frequency be matched to my country’s electrical standard before shipping?
A: Yes. Voltage and frequency are confirmed during the inquiry stage and matched before the machine enters final assembly. This step prevents the commissioning delays that occur when a motor arrives wired for the wrong frequency, which alters vibration timing and block density.
Q: Are spare moulds and hydraulic wear parts included in the shipment?
A: Hydraulic seals, electrical components, and wearing parts are shipped with the machine so replacements are available from the first production run. Additional moulds ordered at the same time load into the same container, reducing freight cost per unit.
