Description
Stocked Configuration — the QTJ4-40 block machine is assembled and factory-tested before your inquiry, not built after, so lead time is measured in days to container loading rather than weeks of production queue.

Why "2400 Blocks per Hour" Means Nothing Without the Format Attached
Every capacity figure on this page is tied to a specific block dimension and mould cavity count — no standalone throughput claims.
I once watched a contractor in the Levant take delivery of a small block machine whose brochure promised impressive hourly numbers. The machine arrived, the crew started running, and the daily tally came in at barely half the expected volume. The reason was simple: the quoted capacity assumed a solid paver format with a short cycle, but the contractor needed hollow blocks with a longer vibration sequence to achieve target strength. The QTJ4-40 block machine in stock fast delivery listing here states its capacity at 2400 pieces per hour based on a 400×200×200 mm hollow block with five cavities per mould and a 40-second cycle. Change the format, and the cycle changes with it. [NEED_CITE: block format impact on cycle time and daily output]
Dispatch Timing That Matches Your Project Calendar
The QTJ4-40 block machine in stock fast delivery is not a build-to-order proposition. The unit is assembled, electrically wired, and run through a factory cycle test before it is listed as available. For buyers working against a construction deadline — a housing phase that needs walls going up, a road project that needs kerbstone on the ground — the difference between a machine that ships next week and one that enters a production queue is the difference between meeting the schedule and explaining delays to a project owner.
Container Loading and Dismantling Clarity
Shipping a stationary block machine means managing weight distribution inside a standard container and planning how the host frame, mixer, and pallets are secured for ocean transit. The QTJ4-40 weighs 1200 kg without the mixer, and the JQ350 vertical mixer ships alongside it as part of the same configuration. Dismantling scope and packing photographs are confirmed at inquiry so the buyer knows exactly what arrives at the port and how it comes out of the container.

Reading the Specifications That Actually Matter on Site
The vibration frequency of 2800 r/min drives the table vibration that settles the concrete mix into the mould cavity. This frequency, combined with the mechanical pressure applied during the 40-second cycle, determines whether the block leaves the pallet with enough green strength to survive handling before curing. The pallet size of 850 × 450 × 20 mm must match the curing rack spacing and the forklift fork width already on site — a mismatch means the buyer either replaces the curing racks or hand-stacks blocks off the pallets. The electrical requirement calls for a 100 A leakage protector with 16 mm² external cabling, which is straightforward for any licensed electrician but must be confirmed against local supply standards before the machine leaves the factory. Voltage and frequency are configurable, and that confirmation is part of the pre-dispatch checklist, not an afterthought at commissioning.
What Happens When Stock Means Unchecked
A machine labeled "in stock" can still ship with the wrong voltage, a mould that does not match the buyer’s target format, or a pallet size that conflicts with the curing yard. The hidden cost is not the machine itself — it is the two weeks of idle crew wages while an electrician rewires the control panel, or the extra pallets ordered at a premium because the originals do not fit the existing rack system. Buyers working to a deadline absorb these delays directly into their project penalties. [NEED_CITE: consequences of unconfirmed voltage and pallet sizing in block machine procurement]
Why Procurement Through This Channel
Block machinery is the single focus here, which means the host machine, mould, pallet, and mixer are specified as one matched set rather than sourced from separate vendors and assembled by the buyer. Configuration is checked against the buyer’s actual block format and local aggregate, not pulled from a catalogue default. Mould design and supply extend to custom drawings when the local market demands a format outside the standard range. Automation level is selectable, so a buyer starting with the QTJ4-40 manual setup has a documented upgrade path to semi-automatic or automatic operation as output requirements grow. Factory test records and packing photographs are provided before shipment, not offered reluctantly after a dispute.

What to Include in Your Inquiry
Provide the block format your market actually sells, the daily volume you need to hit, and the aggregate available locally so the mould and vibration settings can be confirmed before dispatch. State your site voltage and frequency, the control panel language preference, and the curing rack dimensions you already have on the ground. If you are working to a specific project milestone, share the deadline so the QTJ4-40 block machine in stock fast delivery schedule can be mapped against your timeline.
Frequently Asked Questions
Q: Is the QTJ4-40 currently in stock, and what is the dispatch lead time?
A: Availability and lead time are confirmed at the point of inquiry, not assumed from a static listing. The unit is assembled and factory-tested before being offered, so the timeline from order to container loading is measured in days rather than production weeks. You receive a written dispatch estimate before payment is requested.
Q: How is the machine packed and loaded for container shipment?
A: The host machine, JQ350 mixer, and one mould set ship together as a single configuration. Dismantling scope is confirmed at inquiry, and packing photographs are shared before the container is sealed so you know exactly how the equipment is secured for ocean transit and what condition to expect at the port.
Q: Can voltage and frequency be confirmed to my country’s standard before dispatch?
A: The three-phase four-wire electrical system is configurable, and the exact voltage and frequency for your site are verified as part of the pre-dispatch checklist. This avoids the situation where a machine arrives and sits idle while a local electrician reconfigures the control panel and motor wiring.
Q: What mould formats are available besides the included hollow block mould?
A: The standard configuration includes a 400×200×200 mm hollow block mould with five cavities. Additional formats such as solid blocks and pavers are available through mould changes, and custom mould design to buyer drawings is supported when the local market demands a non-standard format.
Q: How long from order confirmation to arrival at my port?
A: The timeline depends on the shipping route and current vessel schedules, but an arrival estimate is quoted at inquiry based on the confirmed dispatch date. You receive the dispatch date and estimated transit duration in writing before committing to the order.
