Used QGM / Zenith block machines: what overseas buyers should confirm

Published 5 November 2026 · Gaotang, Shandong, China

Overseas buyers often shortlist QGM and Zenith equipment because the names appear frequently in used block-machine discussions. Before you compare offers, confirm the model, the real scope of supply, what condition evidence is available, and whether the line will fit your plant. JACK ZHANG Machinery is an independent used machinery trader in Gaotang County, Liaocheng City, Shandong, China — not a manufacturer or authorised dealer.

Why buyers look at QGM and Zenith

QGM and Zenith appear on many overseas enquiry lists for concrete block and brick production. Buyers usually care about mould flexibility, supporting equipment, and whether a used main machine can be matched to their power supply and layout. Brand names alone do not define an offer. On this website, the English equipment card titled “QGM / Zenith equipment” is tagged PHOTO REFERENCE · G01. Its card text is clear: main machines and supporting equipment — confirm the model, condition and scope of supply with Jack.

The photo library for that card includes images labelled Zenith 940, QGM 12-15, QGM ZN900C, QGM 6-15, and generic QGM. Those labels describe photographs in the media library. They do not mean each labelled model is currently for sale. Availability and specifications must be confirmed for each offer.

Confirm the model against photo reference G01

Start by naming the model you want and asking how it relates to the G01 photo set. Useful questions include:

• Which exact model is being discussed for your enquiry?
• Do recent photographs match the machine you are quoting, or are they library reference images?
• Can nameplate details be shared so the year and configuration are verified for that machine?

Brand names on this site identify equipment in the photo library. No manufacturer affiliation is implied. If you want to review the equipment section after reading this article, open the home page equipment cards and use Ask about QGM when you are ready to talk about a specific line.

Scope of supply: machine versus the rest of the line

A second-hand concrete block machine is more than a model name. The site buying guide asks buyers to confirm what is actually included. Treat each item separately:

• Main machine
• Mixer
• Batching equipment
• Conveyors and handling equipment
• Moulds
• Pallets

A photograph does not define the scope of supply. Tell Jack what you will produce — block type, dimensions and target output — because mould compatibility and realistic production depend on the specific machine and your production conditions. If you only need the press, say so. If you need a wider configuration, list the supporting equipment you expect.

Condition checks without guessing

Do not rely on memory of an old listing. Request recent photographs, nameplate details and any available operating footage. Discuss the inspection needed for the frame, vibration, hydraulics and controls. The website FAQ is direct on this point: year, capacity and price are specific to each machine and offer; ask for verified nameplate information and a quotation. Output depends on the product, mould, concrete mix and operating conditions — so avoid treating a brochure figure as a promise for your plant.

These are reference photographs on the website, not a live inventory list. Contact Jack to confirm current availability and request up-to-date information before making a decision.

Site fit, power, shipping and responsibilities

Check whether the equipment will fit your site: power requirements, layout, foundations, access and loading arrangements. Agree on dismantling, transport and responsibilities before an order. For overseas shipments, clarify what is included in packing and freight discussion, who handles export documents, and what remains your responsibility at destination. Keep the conversation tied to one machine offer so the answers stay specific.
