Description
Configuration match over catalogue default — The QTJ4-24 semi automatic block machine in stock ships with JQ350 mixer, 6m conveyor, pallets and trolley as one matched set, not as separate line items sourced from different suppliers.

Why the Pallet Question Matters More Than the Price Tag
A semi automatic block machine in stock only delivers value when the pallet size matches your curing yard and the forklift you already own.
Quotations that leave pallet dimensions until after payment force buyers into curing layouts that waste space or require equipment they do not have. I have seen container loads arrive at port with pallets sized for a forklift the buyer sold the previous year [NEED_CITE: pallet and curing yard compatibility in block production]. The QTJ4-24 runs on 850mm × 450mm pallets — a size we confirm against your yard area and handling equipment before the order is finalized, so nothing arrives mismatched.
Dispatch From Linyi — What "In Stock" Actually Means
When we say a semi automatic block machine in stock is available, it means the QTJ4-24 is assembled, tested and standing in our Linyi yard — not sitting in component form waiting for a build slot. Dispatch lead time is quoted at the inquiry stage, with stocked versus built-to-order status confirmed before you commit payment. This removes the uncertainty that stretches project timelines when a contractor’s foundation work finishes and the machine has not left the factory.
Container Loading and Dismantling Clarity
The QTJ4-24 at 1750 kg total mass fits standard container loading with a defined dismantling plan. We provide packing photographs and a container loading plan before the seal is applied. Machine dismantling points are documented so your team knows exactly which bolts to undo on arrival and in what order to reassemble. Arrival estimates are quoted upfront based on destination port [NEED_CITE: container shipping routes from Linyi to major African and Southeast Asian ports].
How 14.25 kW Shapes Your Electrical Plan
The overall power draw of 14.25 kW keeps this machine within the reach of workshop-level electrical supplies without demanding transformer upgrades or dedicated high-capacity feeders. The two 3 kW lower vibration motors, the 1.5 kW upper vibration device, and the cone-shape elevating motor together stay within a load that most small plants can accommodate. Voltage and frequency are confirmed against your site supply before production begins — a step that prevents the costly delay of commissioning a machine wired for a grid it cannot run on [NEED_CITE: voltage and frequency standards by export market].
When Mould Alignment Fails — The Frame Takes the Load
The dragon gate frame with four wear-resisting vertical shafts is not a cosmetic choice. Platform vibration, driven by two 3 kW motors from below and a 1.5 kW device from above, generates cyclical lateral force on every cycle. A lighter frame allows the mould box to drift from vertical alignment over weeks of production, producing blocks with uneven walls and inconsistent density. The super steel construction and vertical shaft system hold the mould in register across thousands of cycles, keeping hollow block wall thickness and solid brick face dimensions within tolerance without constant manual adjustment. The JZQ250 speed reducer paired with the cone-shape motor controls the elevating stroke with the repeatability that vibration molding demands.
The Cost of Arriving Short
A machine quotation that lists the press but omits the mixer, conveyor, pallets and trolley leaves you sourcing five separate items across different suppliers — each with its own lead time, payment terms and shipping schedule. I have watched block plants sit idle because the 6m belt conveyor was three weeks behind the machine it feeds. Our standard scope includes the QTJ4-24, JQ350 pan mixer, 6m belt conveyor, pallets and trolley as one shipment. The optional auto stacker for 3 to 6 layers can be added at order stage and ships in the same container [NEED_CITE: block production line equipment integration delays].
Why Buyers Source This Machine Through Linyi
The QTJ4-24 is specified and shipped as a single matched system — machine, mould, pallet and handling equipment are not assembled from separate suppliers and hoped to fit together on site. Configuration is set against your target block format and local raw material, not pulled from a catalogue default. Mould design covers the formats your market actually sells, with hollow block and solid brick included as standard. The automation level is selectable: start with manual pallet handling and add the auto stacker when volume justifies it. Installation support with operator training covers reassembly, first-cycle parameter setting and mould change procedure.

What We Need From You to Quote
Send us your target block format and the daily volume you need from the QTJ4-24. Include your local raw material type — whether that is crushed stone, river sand, fly ash or a blend — so we can match vibration parameters to your mix. Confirm your site voltage and frequency, and tell us the pallet size and forklift capacity you already have on site so we size the curing layout correctly.
Frequently Asked Questions
Q: Is the QTJ4-24 currently in stock, or what is the build lead time if I order today?
A: The QTJ4-24 is stocked as a standard model at our Linyi facility. Stocked versus built-to-order status is confirmed at the inquiry stage before payment, and dispatch lead time is quoted based on current availability. If your order requires a non-standard mould or voltage configuration, the build schedule will be stated upfront in the quotation.
Q: What is included in the shipment — does the quote cover mixer, conveyor, pallets and trolley?
A: The standard scope covers the QTJ4-24, JQ350 pan mixer, 6m belt conveyor, pallets and trolley as one matched set. Nothing arrives missing because the quotation lists every included item and every optional item such as the auto stacker or block clamper separately, so you know exactly what is in the container before it ships.
Q: Which container type does the QTJ4-24 ship in, and is dismantling required?
A: The machine at 3600mm × 1700mm × 2560mm in working state requires dismantling at defined points for container loading. A dismantling plan and packing photographs are provided before the container is sealed, and the reassembly sequence is documented so your team can put the machine together on arrival without guesswork.
Q: How long from order to arrival at my port?
A: Arrival estimates are quoted upfront based on your destination port and the current shipping schedule from Linyi. Lead time covers dispatch preparation, container loading, and ocean transit. The estimate is stated in your quotation so you can align machine arrival with your site preparation and foundation work.
Q: If I need the auto stacker, does it ship in the same container?
A: The optional auto stacker for 3 to 6 layers is added at the order stage and typically ships in the same container as the QTJ4-24 and supporting line equipment. If stacking equipment extends the container volume beyond a single unit, the loading plan and any impact on dispatch timing are confirmed in the quotation before you commit.
