The Dispatch Reality Behind "In Stock"
When you need a QTJ4-24 block machine in stock fast delivery is the only metric that matters. A machine is only truly "in stock" when the specific mould format you require is mounted, tested, and crated.
Many quotations state "ready for dispatch" while the required hollow block mould is still in machining. The press frame might be assembled, but without the matched JQ350 mixer and the correct pallet size, the line cannot run upon arrival. We clarify the exact configuration — including the 850mm × 450mm pallet specification and the trolley — before confirming the dispatch date, so your project timeline remains intact [NEED_CITE: container loading schedules and port congestion].
Container Loading and Shipment Integrity
The 1750 kg mass and 3600mm length of this QTJ4-24 block machine in stock fast delivery require precise dismantling planning. The dragon gate frame and vibration box must be secured to prevent shifting during ocean transit. We provide packing photographs and a container loading plan before the doors are sealed.
Matching the Line to Your Curing Yard
A stocked unit must match your existing infrastructure. The 850mm × 450mm pallet size dictates your curing rack dimensions and forklift tine width. Adding the optional auto stacker (3–6 layers) changes the pallet handling flow. We verify these details before release [NEED_CITE: curing yard layout standards for small block plants].
Decoding the Vibration and Power Specs
The 14.25 kW overall power drives a dual-vibration setup: two 3kW motors for the lower platform and a 1.5kW device on the upper platform. This mechanical and electronic combination compacts the concrete mix against the mould walls. The cone-shape motor and JZQ250 speed reducer control the elevating system, ensuring the mould box lifts cleanly without cracking the green block. The 4 pcs hollow block per mould cycle output assumes the 390×190×190mm format; different formats change the cycle dynamics entirely.
The Cost of Unconfirmed Voltage
Shipping a 14.25 kW machine with the wrong frequency rating leads to immediate motor burnout or reduced vibration force. If the PLC display language is not confirmed, operators cannot adjust the cycle time or diagnose faults. These delays occur after the machine has already crossed the ocean [NEED_CITE: voltage and frequency standards by export market].
Why Source This Configuration Here
We treat the QTJ4-24, the JQ350 pan mixer, and the 6m belt conveyor as one matched system, not separate line items. Our stock includes the standard moulds and the trolley required for pallet transport. We confirm the dispatch lead time and arrival estimate at the point of inquiry, allowing you to plan your construction milestone with certainty.

Preparing Your Inquiry
To ensure the QTJ4-24 block machine in stock fast delivery meets your site conditions, specify the block format you intend to produce and the daily volume required. Confirm your local voltage, frequency, and the language required for the electronic control display. If you have an existing curing yard, provide the pallet dimensions and forklift specifications you currently use so we can verify the 850×450mm compatibility.
Frequently Asked Questions
Q: Is the QTJ4-24 currently in stock, and what is the realistic dispatch date?
A: We maintain the QTJ4-24 frame and standard moulds (390×190×190mm and 240×115×53mm) in inventory. However, the realistic dispatch date depends on confirming your voltage and control language requirements. Once these are locked, the machine is tested, dismantled, and crated for container loading. We quote the lead time and arrival estimate upfront at the point of inquiry.
Q: How is the machine dismantled and loaded into a container?
A: The 3600mm × 1700mm × 2560mm frame requires partial dismantling of the dragon gate structure and elevating system to fit securely. We provide a container loading plan and packing photographs before the doors are sealed. The JQ350 mixer and 6m belt conveyor are loaded alongside the main press to ensure the complete line arrives together.
Q: What voltage and frequency configurations are available from stock?
A: The 14.25 kW system, including the 3kW vibration motors and 1.5kW upper device, must be configured for your destination market. Standard configurations are available, but specific frequency requirements may require motor adjustments before dispatch. We confirm this in writing before the machine is released for loading to avoid commissioning delays.
Q: Are moulds and wear parts shipped with the machine?
A: The specific mould format you order is included in the shipment and tested at our facility. Wear parts for the vertical guide shafts and vibration system are listed in the documentation. We clarify whether additional spare moulds are required for your production schedule and include them in the same container to avoid separate lead times.
