QTM4-40 Diesel Moving Block Machine

The QTM4-40 is a heavy‑duty concrete block making machine driven by a diesel engine and hydraulic system. It’s designed for commercial production of a variety of cement blocks and is suitable for both small and large construction projects.

It is a multi‑function machine capable of making hollow blocks, solid blocks, paving blocks, curbstones and AAC (autoclaved aerated concrete) blocks, depending on the mold and mix used.

The machine can produce up to 12,000 blocks in an 8‑hour shift. Actual output varies according to block type, size, mold configuration and operator efficiency.

Common sizes supported include 400×100×200 mm and 240×115×90 mm, among other dimensions. Different molds can be used to produce additional sizes and shapes.

The machine works with typical concrete mixes using materials such as cement, sand and fly ash. It can also produce AAC blocks when the appropriate aerated concrete mix and processing are used.

As indicated by the product name and spec sheet, it uses a diesel engine together with a hydraulic pressure system (pump, pressure vessel) to deliver compression and vibration for block forming. A PLC handles control functions.

The QTM4-40 is semi‑automatic — it reduces manual labor and is designed for easy control, but some operator interaction is required for feeding, mold changes and production management.

Key components include the diesel engine, hydraulic pump, gearbox, pressure vessel, vibration system, PLC controller and forming molds. The unit is built with tested parts and inspected with video and reports.

The machine nominally weighs 3,000 kg and is described as a heavy and stable unit. The documented packing size is 200×200×200 cm with a listed gross weight of 1,000 kg; this packing weight appears inconsistent with the machine weight, so confirm packing and shipping weights with the supplier prior to shipment.

Because the machine is heavy and produces vibration, it should be placed on a stable, level surface or reinforced concrete pad. Final installation and alignment are recommended to be performed by qualified technicians; consult the supplier for site preparation guidelines.

Typical maintenance includes regular hydraulic oil checks and changes, inspection and replacement of filters, lubrication of moving parts, checking bolts and mounting points, monitoring the diesel engine service items, and routine PLC/electrical inspections. Follow the supplier’s maintenance schedule for best results.

The machine is described as easy to operate with basic training. Most suppliers provide basic operator training, commissioning support and machine reports; confirm the exact training and after‑sales services with your vendor.

It is suitable for road and pavement construction, building projects, landscaping, precast block manufacturing and other construction jobs requiring high volumes of concrete blocks.

The product description notes tested parts and machine reports, but spare part availability varies by supplier and region. Ask the vendor for a spare parts list, lead times, and recommended consumables before purchase.

Contact the supplier or distributor to confirm price, lead time, shipping terms (FOB/CIF), exact machine weight and packed dimensions, warranty, training and after‑sales support, and spare parts availability. Request video inspection, machine reports and a detailed quotation prior to placing an order.
